Decentralized, open-source photo sharing platform built on ActivityPub
Pixelfed is a free, open-source photo sharing platform built on ActivityPub, offering a decentralized and privacy-respecting alternative to Instagram. With strong EU community infrastructure and NLnet funding, it federates with Mastodon and the wider Fediverse.

Consider a photographer who has spent years building an audience on Instagram. Their account represents thousands of hours of work — careful composition, consistent editing, community engagement. Then Instagram changes its algorithm. Reach drops by half overnight. Reels get pushed; photo posts are deprioritised. Their audience is still there, but the platform has decided they should see less of what they chose to follow.
Pixelfed is the structural alternative to that situation. A free, open-source photo sharing platform built on ActivityPub — the same protocol that powers Mastodon and PeerTube — it gives photographers and visual creators a platform where the feed is always chronological, where there is no algorithm deciding what gets shown to whom, and where neither the platform owner nor an advertising system has any stake in what gets promoted.
Founded in 2018 and developed primarily by Daniel Supernault with support from NLnet (a Dutch foundation backed by the European Commission's Next Generation Internet programme), Pixelfed federates across a network of independently operated instances. Users join an instance — many of them EU-based — and connect to anyone on any other Pixelfed instance, or to followers on Mastodon, Lemmy, PeerTube, and the broader Fediverse.
Official native apps for Android and iOS launched in January 2025, marking a significant maturation of the platform from a primarily browser-based experience to a fully native mobile product.
Instagram's feed is sorted by an algorithm that factors in engagement bait, advertising revenue potential, and the amount of time Meta calculates you'll spend if shown a particular piece of content. Pixelfed's feed is sorted by time. The most recent post from someone you follow appears first. Nothing is deprioritised because it is not monetisable. Nothing is promoted because an account paid for reach.
This sounds simple, but it is practically unusual. Twitter/X removed its chronological option and restored it only partially. TikTok's entire model is algorithm-first. Instagram has made the chronological option progressively harder to find. Pixelfed's chronological timeline is not a feature that might be removed — it is the architecture.
A Pixelfed account interoperates with the entire ActivityPub ecosystem. A Mastodon user can follow a Pixelfed photographer directly from their Mastodon account. PeerTube and Lemmy users can interact with Pixelfed content through their own platforms. This means a Pixelfed creator's audience is not limited to Pixelfed users — it extends to anyone on any ActivityPub-compatible platform.
Instance federation is configurable: administrators can block specific instances (for content policy reasons) while federating freely with the rest of the network.
Pixelfed supports posts with up to 10 photos or videos, mirroring Instagram's carousel format. Video support extends to clips up to 5 minutes in length and 200 MB in file size. The platform automatically transcodes uploads to WebM/AV1, improving accessibility and reducing bandwidth requirements for viewers on slower connections.
The official Pixelfed apps for Android and iOS — launched in January 2025 — collect no user data. They are available through the Google Play Store and Apple App Store and provide native photo upload, timeline browsing, notifications, and profile management. Before these apps, Pixelfed mobile users relied on third-party clients with variable quality and inconsistent feature support.
Organisations or advanced users can run their own Pixelfed instance. Self-hosting means all photos, user data, and interaction history stay on infrastructure the operator controls. EU-based operators can host on EU servers, apply their own data retention policies, and maintain full GDPR accountability without accepting any third-party platform terms.
Pixelfed is free. The software is open source under AGPL-3.0, and joining any public instance costs nothing — no subscription, no premium tier, no upload limits imposed by the project itself (instance operators set their own limits).
For self-hosting, costs are limited to server infrastructure. A basic VPS with enough storage for a personal photo library starts at around EUR 5-10 per month from European providers. EU-based instances like pixelfed.de and pixelfed.social accept free registrations with their own storage and moderation policies.
Third-party managed hosting providers exist for users who want their own Pixelfed instance without managing server administration. Pricing varies by storage allocation and user count.
The absence of a subscription model means there is no pressure to compromise the product to convert free users to paid tiers. NLnet funding and community donations sustain development without requiring Pixelfed to become a commercial product.
Pixelfed's compliance story has nuance. The project was founded in Canada and the primary developer is Canadian, so there is no EU legal entity behind the software itself. However, the development has received NLnet/NGI0 funding — European Commission money — and the platform has a strong European user base and a significant number of EU-based instances.
For EU users, the relevant compliance question is the instance they join. EU-based Pixelfed instances operate under EU law, store data on EU servers, and are subject to GDPR. Operators of EU instances are the data controllers for their users. The software itself contains no advertising infrastructure, no cross-site tracking, and no profiling mechanism.
The official mobile apps explicitly collect no user data — this is stated in both app store listings and can be verified through the open-source codebase.
Users in the EU who are concerned about data residency should join an EU-hosted instance (pixelfed.de is based in Germany; several others are hosted in the Netherlands, France, and other EU countries) rather than instances operated in North America or elsewhere.
Photographers and visual creators who want to share their work without algorithmic suppression, advertising intrusion, or platform policies that deprioritise still photography in favour of video.
Privacy-conscious users migrating from Instagram who want a familiar format — photo posts, followers, likes, comments — without Meta's data infrastructure.
Fediverse participants already on Mastodon who want to extend their presence to photo sharing through the same social graph without creating a second account on a different network.
Organisations with data requirements that preclude using US-controlled platforms. A self-hosted EU instance keeps all visual content and user data within EU jurisdiction, under GDPR.
Pixelfed is the most direct Instagram replacement available without accepting corporate surveillance. The chronological feed, the absence of advertising, and the ActivityPub federation are genuine structural advantages over any commercial photo platform. The limitations — smaller audience, no Stories or Reels equivalent, and variable discovery — are real. Pixelfed suits creators who have accepted that reach on commercial platforms comes at the cost of platform dependence, and who have decided that trade-off is no longer worth making.
Yes. Pixelfed is free and open source under AGPL-3.0. Joining any public instance is free. Self-hosting an instance costs only server infrastructure. There are no paid tiers or premium features.
Yes. Official native apps for Android and iOS launched in January 2025. The apps are free, collect no user data, and are available through the Google Play Store and Apple App Store.
Pixelfed offers a similar photo-sharing format — posts, follows, likes, comments, direct messages — without advertising, algorithmic feeds, or data harvesting. It lacks Stories, Reels, and Instagram's content discovery network. It suits users who prioritise privacy and platform independence over reach.
Compliance depends on the instance operator. The Pixelfed software contains no tracking or advertising infrastructure. EU-based instance operators are the data controllers and must implement appropriate GDPR policies. Many EU instances maintain strong privacy standards — check the instance's privacy policy before registering.
Yes. Because both platforms use ActivityPub, Mastodon users can follow Pixelfed accounts directly from their Mastodon client. Photos appear in the Mastodon timeline and can be liked and commented on without a separate Pixelfed account.
