Open source Instagram alternatives

Short answerThe open source Instagram alternatives are Pixelfed (AGPL-3.0, fediverse, chronological timelines), Bluesky and the photo apps built on it such as Flashes (open protocol, MIT-licensed Bluesky app), and Emera (open-source code, nonprofit, signed posts). Here is what each is like to use.

Side by side

	Emera	Pixelfed	Bluesky and Flashes
Code	Open source	AGPL-3.0	Bluesky app under MIT; Flashes codebase not found
Run by	Nonprofit	Open-source project; servers run by many communities	Bluesky: public benefit corporation; Flashes: Birdsong Apps GmbH
Protocol	AT Protocol	ActivityPub (fediverse)	AT Protocol
Feeds	Pick your feeds, with a 'Why you are seeing this' reason	Chronological timelines	Over 40,000 feeds to choose from
Provenance on posts	Signed C2PA record on every post	Not described on its repository	Not described on its FAQ
Moving your account	Move it with your followers to another host	Federated; confirm migration on pixelfed.org	Change servers, keep username, friends and posts
Apps	New network	Official and third-party iOS and Android apps	Bluesky on web, iOS, Android; Flashes on Apple devices

Where the others are the better pick

Pixelfed has a license you can read today, a federated network and chronological timelines, plus official iOS and Android apps.
Bluesky is live with a mature app, web, iOS and Android clients and a large feed ecosystem.
Flashes gives Bluesky a photo-first look with filters and portfolios on Apple devices today.

What open source means here

For a social app, open source can mean three different things: the app's code is public, the server's code is public, or the protocol underneath is an open standard anyone can build on. It helps to know which one you are getting, because it decides how much you can move, inspect and self-host.

Pixelfed

Pixelfed is a photo-sharing platform released under the AGPL-3.0 license. Its repository describes it as photo sharing for everyone, without algorithmic gatekeeping. It speaks ActivityPub, so you can follow and be followed across Mastodon and other fediverse apps. Timelines are chronological, with Local, Global and Home feeds. Official apps for iOS and Android launched in January 2025, and third-party apps exist too.

Because Pixelfed is federated, anyone can run a server, and each server sets its own rules. That is the strength of it and also the thing to check before you sign up.

Bluesky and photo apps built on it

Bluesky's app source is published under the MIT license, and AT Protocol is described as an open-source framework for building social apps. Bluesky's FAQ says you can change servers without losing your username, friends or posts. Anyone can build a feed, and its FAQ says there are over 40,000 to choose from.

Because the protocol is open, other apps can read and write the same network. Flashes, from Birdsong Apps GmbH, is a native Bluesky photo and video app for Apple devices with photo filters and portfolio building. We did not find a published Flashes codebase, so treat it as an app on an open protocol rather than an open-source app.

Emera

Emera is a nonprofit network on AT Protocol with open-source code. Each post carries a signed record (C2PA content credentials) of who shared it and when it went up, people are marked while automated accounts are labeled as automated, and reposts point back to the original post. You can pick feeds, and posts show a 'Why you are seeing this' reason. You own your account and can move it with your followers to another host.

Emera is new, so it has a small footprint compared with the options above.
