Best European Low-Code/No-Code Platforms 2026

Why European Low-Code/No-Code Platforms Matter

SeaTable is the best European low-code/no-code platform in 2026, scoring 8.3/10 in our published review ratings — the highest of the nine platforms ranked below, and the only pick with both self-hosting and EU cloud hosting on German servers. The nine span Germany, the Netherlands, Portugal, the United Kingdom, and France, and every one either hosts data in the EU/EEA by default or offers a self-hosted deployment that keeps it there.

This category splits into two genuinely different buyer questions. If you need a database or an app with a database inside it — replacing Airtable, or turning a spreadsheet into a proper relational system — you want SeaTable, Baserow, Softr, or Timetonic. If you are IT modernising legacy systems or standing up governed enterprise applications at scale, you want Mendix, OutSystems, Budibase, Convertigo, or Betty Blocks. Both groups earn their place here, but a citizen developer building an internal directory and an enterprise architect replacing a mainframe front-end are shopping for different things — the "Best for" line on each pick tells you which.

Low-code and no-code adoption is dominated by US platforms: Airtable, Bubble, Retool, Notion, Webflow, Glide, and Microsoft's Power Apps all route data through US-controlled infrastructure by default. For European teams building applications that touch customer records, HR data, or regulated processes, that is a data-residency question every procurement review eventually asks. The nine platforms below, all listed in our low-code/no-code category, answer it with EU jurisdiction, EU hosting regions, or a self-hosting option that removes the vendor from the data path entirely.

Quick Comparison

#1 Pick: SeaTable — Best Self-Hostable No-Code Database

SeaTable tops this list on value for money (9.0/10) and EU compliance (9.5/10). Built in Mainz by the team behind the open-source file-sync tool Seafile, it pairs a spreadsheet-familiar grid with a genuine relational database underneath — links between tables, formula columns, lookups and rollups — plus grid, kanban, gallery, calendar, map and timeline views on the same data. The free tier covers up to 25 users, 10,000 rows and 2 GB storage, comfortably ahead of Airtable's 1,000-record free cap.

What separates SeaTable from most cloud-only competitors is that self-hosting is not a stripped-down fallback. The Enterprise self-hosted licence deploys the full feature set via Docker on infrastructure you control, so a logistics or public-sector team can keep operational records off any third-party server entirely. Cloud pricing is transparent too: Plus is EUR 7 per user per month for 50,000 rows and API access, a fraction of Airtable's comparable tier.

Where it leads: Value for money and EU compliance are both the highest sub-ratings in this ranking. Genuine self-hosting with no feature holdback. A free tier that is actually usable for small teams.

Where it lags: The plugin and extension ecosystem is smaller than Airtable's marketplace. The mobile app is functional but less polished than cloud-native rivals. Documentation and community resources lean heavily German-language, which creates friction for international teams — support quality scores 7.0/10, the lowest sub-rating on its card.

Best for: European operations and logistics teams that have hit compliance friction with Airtable and want a structurally equivalent tool with German hosting or full self-hosting. See how it stacks up in our SeaTable vs Baserow comparison.

#2 Pick: Baserow — Best Open-Source Airtable Alternative

Baserow is fully open-source under a permissive licence and self-hostable via Docker, with Baserow B.V. holding zero access to your data once you do. The Amsterdam-based platform stores cloud data specifically in Amsterdam — not a vague "EU region" — and carries GDPR, HIPAA, and SOC 2 Type II compliance across every tier, not gated behind an enterprise plan. Ease of use scores 8.5/10, the joint-highest in this ranking.

Beyond the database core, Baserow includes an application builder that turns tables into shareable web apps, an automation engine with branching logic, and a 2026-era AI assistant that generates full database structures from a plain-language prompt. Pricing undercuts Airtable sharply: Premium is EUR 5 per user per month for 50,000 rows, against roughly $20/user/month for Airtable's comparable Team plan.

Where it leads: Triple compliance certification (GDPR, HIPAA, SOC 2 Type II) at every pricing tier, and the cleanest open-source self-hosting story in the category — zero vendor telemetry when self-hosted.

Where it lags: The template and integration ecosystem is smaller than Airtable's marketplace. Cloud row limits (3,000 free, 50,000 Premium, 250,000 Advanced) can force an upgrade sooner than expected without self-hosting. Enterprise pricing requires a sales conversation rather than transparent self-serve rates.

Best for: GDPR-conscious teams replacing Airtable or Google Sheets who want triple compliance certification without paying for an enterprise tier. Compare it directly against SeaTable in our Baserow vs SeaTable comparison.

#3 Pick: Softr — Best for Client Portals and Internal Tools

Softr is the Berlin-built answer to Bubble, Glide, Adalo, and Retool, and it posts the highest integration-ecosystem score in this ranking (8.5/10) because it connects to eight data sources — Airtable, Google Sheets, Notion, PostgreSQL, MySQL, MariaDB, Supabase, and HubSpot — without duplicating data into its own store. That makes it the fastest route from an existing spreadsheet or database to a production client portal with authentication and role-based access built in.

SOC 2 Type II certification and an EU hosting option give it enterprise-credible compliance for a German GmbH, and its 2026 AI Generator produces a working app scaffold from a text prompt. The trade-off is record-limit-driven pricing: Basic ($59/month) caps at 5,000 records, and teams with active customer lists often need Professional ($167/month) or Business ($323/month) sooner than budgeted.

Where it leads: Multi-source data connectivity without migration, purpose-built portal blocks (authentication, roles, payments), and the strongest integration rating on this list.

Where it lags: The formula and conditional-logic builder is less powerful than Retool or Bubble for complex business logic. Custom JavaScript blocks require the Professional plan. There is no native mobile app export — Softr apps run as browser-based PWAs, not native iOS or Android builds.

Best for: Teams building authenticated client portals or internal tools on top of data that already lives in Airtable, a SQL database, or Supabase, and want EU hosting without a compliance conversation. Pair it with Baserow or SeaTable as the backend for a fully EU-hosted stack.

#4 Pick: Mendix — Best Enterprise Low-Code (Siemens-Owned)

Mendix has an ownership note worth stating plainly: it is a Dutch platform founded in Rotterdam in 2005, acquired by Siemens AG — a German industrial group — in 2018 for $730 million. It now operates as Siemens Industry Software Netherlands B.V., an EU legal entity with an EU parent company, which keeps its data-sovereignty story intact even though it is no longer independently owned. Feature depth is the category's joint-highest at 9.0/10.

The platform generates true native mobile apps via React Native, not wrapped web views, and offers Maia, an AI assistant embedded directly in Studio Pro that suggests logic, flags anti-patterns, and accelerates workflow design. Deployment flexibility is unmatched among the enterprise picks here: Mendix Cloud in Frankfurt with Dublin backup, private cloud on Kubernetes, or fully air-gapped on-premises. The certification stack — ISO 27001, 27017, 27018, 27701, SOC 1 and 2 Type II — is the deepest in this ranking.

Where it leads: Feature depth and EU compliance (9.5/10) are both the highest or joint-highest scores here. Genuine native mobile output and Kubernetes-based air-gapped deployment for regulated industries.

Where it lags: Vendor lock-in is real — apps cannot be exported as portable source code, a limitation Betty Blocks explicitly avoids. Value for money is the lowest sub-rating on its card (6.0/10): the Standard plan jumps to roughly EUR 918/month with a steep gap from the free tier. The learning curve is steeper than simpler no-code tools.

Best for: Enterprise IT departments running a portfolio of governed internal applications, especially organisations already inside the Siemens ecosystem or needing air-gapped Kubernetes deployment.

#5 Pick: OutSystems — Best High-Performance Enterprise Platform

OutSystems, founded in 2001 in Linda-a-Velha, Portugal, is the only one of the big three enterprise low-code vendors (alongside Mendix and Microsoft Power Apps) that is both EU-headquartered and independently owned. Its defining technical choice is compiling visual models into optimised C#/.NET code rather than interpreting them at runtime, which delivers production performance closer to hand-coded applications than most low-code output. Feature depth ties Mendix at 9.0/10.

Mentor, its 2025-launched agentic AI system, orchestrates more than ten specialised agents to generate multi-screen applications from a requirements document — genuinely production-grade output, not a wireframe. The compliance portfolio (SOC 1/2 Type II, ISO 27001/22301/27017/27018/9001, PCI DSS, HIPAA, TISAX) is the broadest in this ranking, and EU data residency is selectable on AWS infrastructure.

Where it leads: Native code generation for production performance, the deepest compliance certification list here, and no per-developer-seat licensing regardless of team size.

Where it lags: Value for money is the lowest score in the entire ranking (5.5/10) — OutSystems Developer Cloud starts at $36,300/year, with average enterprise contracts running around $220,000. The free evaluation is capped at 10 days, tight for anything beyond a proof of concept.

Best for: Large enterprises modernising legacy systems where the cost of a six-figure licence is smaller than the cost of the technical debt it replaces. Not a fit for startups or teams where that budget line is significant.

#6 Pick: Budibase — Best Self-Hosted Internal Tools (UK-Based)

Budibase is UK-based — headquartered in Belfast, outside the EU post-Brexit but operating under UK GDPR, which mirrors EU GDPR and carries a European Commission adequacy decision. It is open-source (AGPL v3 for the builder), and the self-hosted Open Source edition is free with unlimited users and apps on a single workspace, deployed via Docker or Kubernetes. Value for money scores 8.5/10, second only to SeaTable in this ranking.

It connects natively to PostgreSQL, MySQL, MongoDB, Microsoft SQL Server, and MariaDB as an external data proxy — credentials stay server-side, never exposed to the browser — and includes a 20-block automation engine plus a 2026 AI agent builder via LiteLLM. Cloud hosting runs in Ireland on ISO 27001-certified infrastructure, though the cloud free tier was discontinued in March 2026, making self-hosting the only route to genuinely free usage now.

Where it leads: The most capable free self-hosted tier in this ranking (unlimited users and apps), granular RBAC with SSO/SCIM on Enterprise, and database connectivity that treats your existing data as the source of truth.

Where it lags: It is explicitly built for internal tools, not customer-facing applications — the component library is smaller than Retool's. Budibase is not SOC 2 Type II certified as a company, only its data centres are, which matters for regulated-industry procurement. Support quality is the lowest sub-rating on its card (6.5/10).

Best for: IT teams shipping internal tools and admin panels who want Retool-class functionality without Retool-class pricing, and who are comfortable with UK GDPR rather than requiring strict EU-27 jurisdiction.

#7 Pick: Timetonic — Best French-Hosted Database With Native AI

Timetonic hosts all data exclusively in French data centres run by French operators, making it immune to the US CLOUD Act by design — a sovereignty position matched only by Convertigo in this ranking. Founded in 2011 near Paris, its Smart Tables give business users a relational database with spreadsheet-style views (grid, kanban, calendar, Gantt), and it is one of the only no-code platforms with a genuinely offline-capable native mobile app for field teams.

The standout feature is native Mistral AI integration, configured without code, for document extraction, record classification, and summarisation — all processed inside the same French hosting environment as the rest of the platform. Client references include AP-HP (Paris's public hospital system), Engie, and the Occitanie Region, and HDS-certifiable hosting extends the platform into regulated healthcare use cases.

Where it leads: EU compliance ties the category's best score (9.5/10) via CLOUD Act immunity and HDS/SecNumCloud-compatible hosting. Offline mobile capability and automated document generation serve field-operations workflows most competitors handle poorly.

Where it lags: Ease of use is the lowest sub-rating in this ranking's database tier (6.5/10) — the interface feels enterprise-functional rather than modern next to Airtable or Notion. English-language documentation trails the French experience, and the integration ecosystem (6.5/10) is thinner than Softr's or SeaTable's.

Best for: French and European public-sector or healthcare organisations where HDS certification or CLOUD Act immunity is a procurement requirement, and field teams that need offline data capture.

---

#8 Pick: Convertigo — Best Open-Source Offline-Capable Mobile Platform

Convertigo has the longest history in this ranking — founded near Paris in 1994, rebranded in 2009 — and it is the only fully open-source enterprise low-code platform here, licensed under AGPL 3.0 with genuine on-premise Docker deployment and no feature gates on the Community edition. Value for money scores 9.0/10, second only to SeaTable, because the core platform costs nothing and paid cloud starts at just EUR 15/month.

Its Full Sync engine, built on CouchDB replication, delivers offline data synchronisation with automatic conflict resolution deeper than what OutSystems or Power Apps offer, making it a strong fit for field-service and logistics apps that need to keep working without connectivity. The company itself is small — around 13 people — which shows up directly in its ratings.

Where it leads: The only genuinely open-source, fully auditable low-code platform in this ranking, with EU compliance tied for the category's best (9.5/10) via on-premise deployment and OVHcloud France hosting.

Where it lags: Ease of use is the lowest score in the entire ranking (6.0/10) — the Eclipse-based Low Code Studio feels dated next to browser-native competitors. Support quality also ties for last (6.0/10), a direct consequence of the 13-person team, and documentation is functional rather than polished.

Best for: Enterprise integration teams connecting modern frontends to legacy SOAP services or mainframes, and budget-conscious IT departments that need low-code capability without a five-figure annual licence.

---

#9 Pick: Betty Blocks — Best for Citizen-Developer Governance

Betty Blocks, founded in Alkmaar in 2012, closes this ranking with the most unusual pricing model in the category: development-only billing, where end users and idle applications cost nothing. Betty Blocks was the first no-code platform to achieve ISO 27001 certification, audited by Kiwa, covering the platform itself rather than just its hosting provider.

Its architecture rebuild onto React and WebAssembly means applications export as portable code that runs on any infrastructure — a direct answer to the vendor lock-in that defines Mendix and OutSystems in this same ranking. Ease of use scores 8.0/10, reflecting Betty Blocks' claim that business users become productive after roughly one day of training, well below the learning curve of the professional-developer platforms above it.

Where it leads: Genuine no-code portability (React + WebAssembly export) that neither Mendix nor OutSystems offer, development-only pricing that can save large deployments millions annually, and governance tooling built for citizen development from the ground up.

Where it lags: There is no free tier or self-service trial — every evaluation starts with a sales call, real friction for teams wanting to try before committing. The integration ecosystem is the second-lowest in this ranking (6.5/10), and complex business logic still hits the limitations of a true no-code abstraction faster than on Mendix or OutSystems.

Best for: Business teams inside regulated EU enterprises that need custom applications without deep development resources, and organisations trying to escape per-user licensing costs on Power Apps or OutSystems.

Which Should You Choose?

If you need a database to replace Airtable, choose SeaTable for the strongest self-hosting story or Baserow for the broadest compliance certification at every tier. If you need a client portal or internal tool on top of existing data, Softr connects to eight sources without migration. If you are building enterprise applications at scale with governance requirements, Mendix and OutSystems lead on feature depth — Mendix if Siemens ecosystem integration or Kubernetes air-gapping matters, OutSystems if native code performance is the priority and budget allows a six-figure contract. If your budget does not allow that, Budibase and Convertigo deliver open-source, self-hostable alternatives at a fraction of the cost. If CLOUD Act immunity and French sovereign hosting are procurement requirements, Timetonic is purpose-built for that. If portability and citizen-developer governance matter more than raw feature depth, Betty Blocks is the only pick here whose applications export as standard code.

How We Chose

Every platform here has a verified European headquarters or an EU parent company recorded in its EuropeanStack review, and the ranking order follows the overall ratings published in those reviews — scored across ease of use, feature depth, value for money, EU compliance, support quality, and integration ecosystem. Where overall scores tie (Convertigo and Betty Blocks both hold 7.5/10), order is decided by the EU-compliance sub-rating first and value for money second: Convertigo's 9.5/10 EU-compliance and 9.0/10 value scores place it above Betty Blocks' 9.0/10 and 7.5/10. All pricing is restated from each product's verified data file (verified March 2026 for most platforms; May 2026 for Softr), in the currency each vendor bills in. We do not conduct hands-on testing; rankings reflect our published editorial assessments.

Notable Exclusions

Several reviewed and known products from the category did not make the ranking. n8n, Make, and Automatisch are workflow automation platforms first — their primary category is automation, not app or database building — so they are ranked in our European workflow automation roundup instead. Brizy (7.9/10, Romania) is excluded because its primary category is landing-page building, not low-code/no-code; it appears here only as a secondary tag.

WeWeb (7.5/10, France) ties the ranking's lowest overall score but falls below the cut on our declared tie-break: its EU-compliance sub-rating is 6.5/10, the lowest in the category, because its default hosting runs on AWS US-East (Virginia) rather than an EU region — EU hosting requires exporting and self-hosting its code. Activepieces, the open-source workflow and no-code builder, does not qualify as European at all: it is incorporated as Activepieces Inc. in San Francisco, per its own terms of service, despite a popular open-source community edition.

Among US incumbents, Airtable, Bubble, Retool, Webflow, Glide, Notion, Microsoft Power Apps, and Appian remain the products most European teams are migrating away from — see our Airtable alternatives, Retool alternatives, Power Apps alternatives, and Appian alternatives pages for the full European shortlist against each.

Frequently Asked Questions

What is the best European low-code/no-code platform?

SeaTable is the best European low-code/no-code platform in 2026, with the category's highest overall rating (8.3/10), built around a self-hostable no-code database with German cloud hosting. Baserow (8.2/10) is the better pick if open-source licensing and triple compliance certification (GDPR, HIPAA, SOC 2) matter most, and Softr (8.1/10) leads for client portals built on existing data sources like Airtable or Supabase.

Is there a European alternative to Airtable?

Yes. SeaTable, Baserow, and Timetonic all replicate Airtable's spreadsheet-meets-database model with EU hosting or self-hosting. SeaTable and Baserow both undercut Airtable's pricing significantly at every tier, and Baserow adds HIPAA and SOC 2 Type II certification across the board. Softr is not a direct Airtable replacement but is commonly paired with Baserow or SeaTable as the backend for a fully EU-hosted portal stack. See the full European alternatives to Airtable.

Is there a European alternative to Bubble or Retool?

Softr is the closest European match for Bubble-style client portals and Retool-style internal tools when the data already lives in a spreadsheet or SQL database, though it has less complex-logic depth than either. Budibase is the more direct Retool alternative for internal admin tools, open-source and self-hostable at a fraction of Retool's per-user pricing. See European alternatives to Retool.

Which European low-code platforms are open source?

Three of the nine ranked platforms are fully open-source and self-hostable: Baserow (self-hosted edition free with no row limits), Budibase (free self-hosted Open Source edition, unlimited users), and Convertigo (free Community edition with no feature gates). SeaTable is not open-source but offers a licensed self-hosted Enterprise edition with the complete feature set. All four remove the vendor from the data path entirely when self-hosted.

How much do European low-code and no-code platforms cost?

The no-code database and portal tier is affordable: SeaTable's Plus plan is EUR 7/user/month, Baserow's Premium is EUR 5/user/month, and Softr's Basic plan starts at $59/month. The enterprise low-code tier costs far more: Mendix's Standard plan runs roughly EUR 918/month, and OutSystems starts at $36,300/year with average contracts around $220,000/year. Budibase and Convertigo sit between the two, with paid cloud plans starting under EUR 20/month and free self-hosting available on both.
