Open Source Social Media Scheduler: 7 Options for 2026

These are the projects with a real license, a public repository and commits in 2026. Networks are what each README lists as supported for publishing, not roadmap items.

Two things the table makes obvious. AGPL-3.0 (Postiz, BrightBean, TryPost) is fine for internal use, but if you modify the code and offer it to users over a network, you have to publish your changes. MIT and Apache-2.0 (Mixpost Lite, Shoutrrr) do not ask for that. And network count varies a lot: Mixpost Lite publishes to three networks, Postiz to more than a dozen.

Yes, by a wide margin. gitroomhq/postiz-app had more than 41,000 stars and 7,800 forks when we checked, with pushes every day. It is a TypeScript monorepo (Next.js, NestJS, Prisma on PostgreSQL, Temporal for workflows) and the README lists X, LinkedIn, Instagram, Facebook, TikTok, YouTube, Pinterest, Threads, Bluesky, Mastodon, Reddit, Discord, Slack and Dribbble, among others.

Postiz says the self-hosted edition and Postiz Cloud share the same core and that it does not gate features behind the license. The difference is operational. Its own README table puts it plainly: self-hosted, you configure Postgres, Redis, storage and environment variables, and you create your own developer app on each platform, where approval from Meta, YouTube or TikTok "can take weeks". Postiz also ships an MCP endpoint and an agent CLI, so tools like Claude can schedule through your instance. If Postiz is on your shortlist, our PostGate vs. Postiz comparison goes feature by feature.

inovector/mixpost is the MIT-licensed Lite edition of a commercial product, built on Laravel and Vue, with about 3,900 stars. The catch is the network list. According to the Mixpost pricing page, Lite publishes to Facebook Pages, X and Mastodon only. Instagram, LinkedIn, YouTube, TikTok, Pinterest, Threads, Bluesky and Google Business Profile are in Pro ($299 one-time) and Enterprise ($1,199 one-time, which adds subscription billing so you can resell it as a SaaS).

Paid licenses include one year of updates and are source-available rather than open source. The public Lite repository had its last push in March 2026, so most active development now happens in the paid editions. Mixpost is a good fit if you already run Laravel and expect to pay for Pro; it is a weak fit if you want a free scheduler for Instagram or LinkedIn.

BrightBean Studio is the newcomer of 2026: the repository was created in March and passed 2,600 stars by November. It is Django on PostgreSQL, AGPL-3.0, and aimed squarely at agencies, with workspaces per client, custom roles, approval stages, a passwordless client portal for sign-off and a unified inbox for comments and DMs. The README says every feature is available to every user, with no paid tier, and there is also a free hosted version.

It publishes to 12 networks, including LinkedIn company pages, Google Business Profile and DEV.to, which few open source tools cover. One practical detail from its setup docs: with local storage, uploaded media is served publicly because Instagram, Threads, Facebook and Pinterest fetch media URLs from your server when publishing. Any self-hosted scheduler has the same requirement, and it is easy to miss behind a firewall.

TryPost (AGPL-3.0, PHP, about 800 stars) positions itself as a scheduler built for AI agents. It exposes an MCP server with more than 80 tools plus a REST API, and lists 13 networks, including Telegram, Discord and Google Business. There is a hosted TryPost Cloud as well.

Shoutrrr comes from the team behind Coolify and is Apache-2.0. It runs the web app, queue worker and scheduler in a single Docker image and defaults to SQLite, so it is the easiest project here to run on a cheap VPS. It covers seven networks (X, Bluesky, LinkedIn, Facebook Pages, Instagram, Threads, Discord), with no TikTok or YouTube, and supports TOTP and passkeys for sign-in.

postiz-cheap (MIT, 1,300+ stars) is an independent Next.js scheduler with an AI writer, unrelated to Postiz despite the name. Read the README before you count it as self-hosted publishing: accounts connect through MuAPI, a third-party service, so your app runs on your server but the posting goes through someone else.

Post4U (MIT, about 120 stars, Python) cross-posts to X, Reddit, Telegram, Discord and Bluesky and only retries the platforms that failed. It is a single-maintainer project with its last push in March 2026, so treat it as a base to fork rather than something to depend on.

• You need TikTok, YouTube and Reddit in one place: Postiz.
• You run an agency with client approvals: BrightBean Studio, or Postiz if you need more networks.
• You want one small container and the main text networks: Shoutrrr.
• Posts will come mostly from AI agents: TryPost or Postiz, both with MCP. Our n8n alternatives for social media post covers the automation side.
• Your team is on Laravel and has budget for a license: Mixpost Pro.

We left out projects we could not verify as maintained. Shoutify (Apache-2.0, about 400 stars) still ranks in roundups, but its last commit was in January 2023. The Free-AI-Social-Media-Scheduler repo this page listed in August no longer resolves on GitHub.

The license is free; the work is not. Every project above leaves the same jobs with you: a database and a background worker that has to wake up on time, a developer app on each network with its own review (Meta, TikTok and YouTube are the slow ones), OAuth token refresh, public media URLs, and fixing the integration when a platform changes its API. Our explainer on how social media schedulers work walks through each of those pieces, which is a good way to estimate the effort before you deploy.

For one person or a small team with the appetite for it, that is a good trade: full control, no per-seat fees and code you can read. LinkedIn is a typical example of where it gets fiddly, since its API has no native scheduling, as we explain in how to schedule LinkedIn posts.

The trigger is usually that you are building a product on top of social publishing rather than running a scheduler for your own accounts. Then the open source app is not the part you need; the publishing layer is. PostGate is that layer as a hosted API: you create a hosted connection URL for each customer, token health is monitored for you, and every post returns delivery evidence per destination. The open source vs. managed comparison lays out the tradeoff in more detail.
