Open-source Postiz alternatives

TrackMedia is a hosted content distribution tool for creators, in-house marketing teams and agencies. You write one master draft and it prepares a version for each connected network, checking limits such as character counts and image aspect ratios before the post goes out. The goal is to cut the effort of posting the same material to many platforms.

Beyond scheduling with timezone support, it handles threads, carousels, first comments and alt text, and can crosspost from one account to others with platform-specific adjustments and deduplication. Every link becomes a short tracked link with UTM tags, so analytics show which post on which network drove clicks, alongside impressions, saves, shares and followers. A REST API with a TypeScript SDK, a CLI and an MCP server support automation and use from AI assistants.

Supported networks include LinkedIn, X, Instagram, Threads, Bluesky, TikTok, YouTube, Facebook, Pinterest, Reddit, Mastodon, Telegram and Discord, among others. TrackMedia is a proprietary SaaS product with a free tier; its site states that every network is included in every plan and that no card is needed to sign up.

n8n is a workflow automation platform for connecting apps, moving data between them and triggering actions without writing a full integration from scratch. Workflows are built on a visual canvas, and when a step needs more logic you can drop in JavaScript or Python and use npm packages. It is often compared with Zapier and Make, but the source is public and it can run on your own infrastructure.

Recent versions put a lot of weight on AI. You can build multi-step agents and LLM workflows that call OpenAI, Anthropic, Google or open-source models, add human approval steps, and inspect what happened afterward. The project advertises over a thousand integrations and a large library of ready-made workflow templates, and you can extend it with your own nodes.

n8n is distributed under a fair-code model: the Sustainable Use License, plus a separate enterprise license for additional features. The code is always visible and can be self-hosted, for example with Docker, but it is not an OSI-approved open-source license, so commercial redistribution is restricted. A managed cloud edition is available if you would rather not run it yourself.

BrightBean Studio is an open-source social media management platform for creators, agencies, and small businesses. It covers what tools like Buffer, Sendible, and SocialPilot do, planning, composing, scheduling, approving, and publishing posts, but without per-seat, per-channel, or per-workspace limits. It is built with Django, HTMX, and Tailwind CSS and released under the AGPL-3.0 license.

A single multi-workspace dashboard connects to Facebook, Instagram, LinkedIn, TikTok, YouTube, Pinterest, Threads, Bluesky, Google Business Profile, Mastodon, and DEV.to. Features include unlimited organizations, workspaces, and members with role-based access and a client role for outside collaborators, and a content composer with per-platform overrides, version history, templates, and categories. All integrations use the official first-party APIs with your own developer credentials.

The README says every feature is available to every user, with no paid tier. You can deploy it with one-click buttons on Heroku, Render, or Railway, run it with Docker on your own VPS, or use a free hosted version at brightbean.xyz/studio. It suits agencies that manage many client accounts and want to own their social stack.

Mixpost is a social media management platform that you run on your own server, positioned as an open-source alternative to Buffer. It helps brands, agencies and small businesses plan, schedule and publish content from a single place, without a per-seat subscription.

You can bring all your social accounts together, build a content calendar and schedule posts for the times your audience is most active. Team features let you assign tasks, manage permissions and watch team performance. Analytics show audience behavior for each platform based on the data that the networks provide.

Mixpost is built with Laravel, PHP and Vue and is licensed under MIT. The project says it targets enterprises, small and medium businesses, marketing agencies, solopreneurs and e-commerce stores. Its description promises no subscriptions and no limits, since you host it and control the data yourself.

Shoutrrr is a social media scheduling tool that you run yourself. You connect your accounts, draft a post once and send it to several networks at the same time or queue it to go out on a recurring schedule. It is presented as an open-source alternative to Buffer, Typefully and Hootsuite, with no monthly seat fees and no third party holding your tokens or data.

Supported platforms include X, Bluesky, LinkedIn, Facebook, Instagram, Threads and Discord, and the text can be adjusted per network. A posting queue with recurring time slots and a month calendar keeps the feed consistent, and analytics show how posts perform. Teams get workspaces, roles and email invites, so clients or brands can be kept separate.

It is written in PHP, runs anywhere Docker does and is released under the Apache 2.0 licence. The project comes from the coollabsio organization and is relatively new, with its first release in mid-2026.
