Betty Blocks

What Is Betty Blocks?

Most enterprise no-code platforms make a promise they cannot keep: build anything, no coding required. Betty Blocks, founded in Alkmaar in 2012, makes a narrower and more honest claim — it lets citizen developers build business applications fast, with IT keeping the guardrails in place.

The company sits in a peculiar niche. It is not Mendix or OutSystems, which are low-code platforms targeting professional developers who happen to want visual tooling. Betty Blocks is aimed squarely at business users — operations managers, process analysts, department leads — who need custom applications but lack the budget or patience to wait for IT to build them. The platform provides a visual drag-and-drop builder, a Block Store of pre-built modules, and workflow automation tools that let non-technical teams go from prototype to production in weeks rather than months.

What changed in 2025 is the architecture. Betty Blocks rebuilt its platform on open standards: React for the frontend, WebAssembly for the backend. Applications export as portable code that runs on any infrastructure — Azure, AWS, on-premise, wherever. This is a direct attack on the vendor lock-in that plagues competitors like OutSystems and Appian, where leaving the platform means rebuilding from scratch. For a no-code tool, that level of portability is genuinely unusual.

The company has raised approximately $36 million across two funding rounds, employs around 150-200 people, and counts enterprise customers across finance, government, and logistics. It is profitable enough to operate without chasing hypergrowth capital, which gives it a stability that matters when you are building business-critical applications on someone else's platform.

Key Features

Visual Application Builder

Betty Blocks' core builder is a drag-and-drop environment where users assemble applications from pre-configured blocks. Data models, forms, pages, and workflows are all created visually. The learning curve is genuine — Betty Blocks estimates one day of training for business users to become productive — but it is far shorter than OutSystems or Mendix, which assume developers as the primary audience. The interface is clean and logically structured, though power users will occasionally hit walls when trying to implement edge-case business logic that falls outside the platform's visual abstractions.

Betty Genius AI

The platform's generative AI feature, Betty Genius, lets users describe an application in natural language and receive a working prototype. It accelerates the earliest phase of development — going from idea to clickable mockup — but should not be mistaken for a finished product. The AI-generated scaffolding still requires manual refinement of data models, permissions, and integrations. It is useful, not magic.

Block Store

Think of it as an app store for building blocks. The Block Store offers pre-built modules, UI components, functions, and themes — including integrations with Google Maps, Salesforce, and common enterprise APIs. This is where Betty Blocks compensates for its no-code limitations: if the block exists, implementation is fast. If it does not, you are waiting for Betty Blocks or the community to build it.

Governance and Access Control

Enterprise IT departments will appreciate the governance layer. Betty Blocks provides role-based access control, project versioning, and audit logging. IT teams can define what citizen developers are allowed to build, which data they can access, and enforce approval workflows before applications go live. This is the feature that separates Betty Blocks from consumer no-code tools like Bubble — it is designed for environments where compliance and oversight are non-negotiable.

Open-Standards Architecture

The most significant technical differentiator. Applications built on Betty Blocks compile to standard React (frontend) and WebAssembly (backend), with support for Rust, TypeScript, Python, and .NET on the server side. You can export your application and run it independently. No other major no-code platform offers this level of portability. Whether enterprises will actually exercise this exit option is debatable, but having it fundamentally changes the power dynamic with the vendor.

Pricing

Betty Blocks overhauled its pricing model in 2025, and the result is genuinely different from the industry norm. The platform charges only for active development work. End users pay nothing. Applications that are live but no longer being modified carry no platform costs.

Compare this to Microsoft Power Apps, where 400 users needing premium connectors costs roughly EUR 90,000 per year. A comparable Betty Blocks deployment runs around EUR 10,000. For enterprises operating 30 or more applications, Betty Blocks claims savings of EUR 3-5 million annually over traditional per-user licensing.

The catch: pricing is entirely custom. There is no self-service signup, no public price list, and no free trial without talking to sales. For a platform that markets to citizen developers, this enterprise-sales-only approach creates real friction. You cannot kick the tyres before committing, and that is a significant barrier for smaller organisations or teams exploring no-code for the first time. Contracts are annual.

EU Compliance & Privacy

Betty Blocks holds ISO 27001 certification — audited by Kiwa — making it the first no-code platform to achieve this standard. The certification covers the platform itself, not just the hosting provider, which is a meaningful distinction.

The public cloud runs on Microsoft Azure within EU regions. For organisations needing stricter data sovereignty, Betty Blocks supports on-premise and private cloud deployments, meaning data never has to leave your own infrastructure. A GDPR-compliant data processing agreement is standard. The Dutch headquarters (Betty Blocks B.V., Alkmaar) means the company falls under EU jurisdiction by default — no Privacy Shield workarounds, no adequacy decision dependencies.

For regulated industries — finance, healthcare, government — the combination of ISO 27001, EU hosting, and on-premise option covers most compliance checklists. It is not as certification-heavy as some competitors (no SOC 2 Type II, for example), but the ISO 27001 scope is broad and the deployment flexibility compensates.

Who It's Best For

Business teams in regulated EU enterprises that need custom applications but lack development resources. The governance layer and ISO 27001 certification satisfy compliance requirements that rule out consumer-grade no-code tools.

Organisations escaping per-user licensing costs. If you are running dozens of applications with hundreds of end users, the development-only pricing model delivers measurable savings over PowerApps, Mendix, or OutSystems.

IT departments enabling citizen development. Betty Blocks' governance controls let IT maintain oversight without becoming a bottleneck. The open-standards export provides a credible exit strategy if the platform no longer fits.

European organisations prioritising data sovereignty. Dutch HQ, EU hosting, on-premise option — the full stack for organisations that need to demonstrate data stays within EU borders.

The Verdict

Betty Blocks occupies a defensible position in the enterprise no-code market. The open-standards architecture is genuinely differentiated. The development-only pricing is bold and, for the right organisation, dramatically cheaper than alternatives. The EU compliance story is strong. But the lack of a free tier, the sales-gated evaluation process, and the inherent limitations of no-code for complex logic mean it is not for everyone. If your use case fits — business applications, citizen developers, enterprise governance — Betty Blocks is one of the strongest European options available. If you need deep customisation or developer-grade flexibility, look at Mendix or OutSystems instead.

Frequently Asked Questions

Is Betty Blocks GDPR compliant?

Yes. Betty Blocks is a Dutch company (Betty Blocks B.V.) headquartered in Alkmaar, fully subject to EU jurisdiction. The cloud platform runs on Microsoft Azure within EU regions, and the company offers on-premise deployment for organisations requiring complete data sovereignty. ISO 27001 certification covers the platform end-to-end.

How does Betty Blocks pricing compare to PowerApps?

Betty Blocks charges only for active development — end users pay nothing. Microsoft Power Apps charges per user per month, which scales linearly with adoption. For a deployment with 400 users needing premium connectors, PowerApps costs roughly EUR 90,000 per year versus approximately EUR 10,000 on Betty Blocks. The gap widens with more applications and users.

Can I export applications built on Betty Blocks?

Yes. Applications compile to standard React (frontend) and WebAssembly (backend). You can export and deploy them independently on any infrastructure. This is a significant differentiator — most no-code and low-code platforms create proprietary artifacts that cannot run outside the platform.

Is Betty Blocks suitable for complex enterprise applications?

For workflow-driven business applications — portals, forms, approval processes, internal tools — yes. For applications requiring highly custom UI, complex algorithmic logic, or deep system integrations, you will likely hit the boundaries of what no-code can express. In those cases, a low-code platform like Mendix or OutSystems provides more flexibility at the cost of requiring developer skills.

Does Betty Blocks offer on-premise deployment?

Yes. Betty Blocks supports on-premise, private cloud, and multi-cloud deployment. Applications built on the platform are portable thanks to the open-standards architecture, so you are not locked into Betty Blocks' own cloud infrastructure.
