Self-hostable social media scheduling tool with analytics, team collaboration and an API, covering platforms like X, Bluesky, Mastodon and Discord.
Postiz schedules social media posts across accounts and gives a team one place to plan them. It positions itself against Buffer, Hypefury and similar hosted schedulers, with the difference that the self-hosted version currently holds nothing back from the hosted one.
The stack is a pnpm monorepo with Next.js on the front, NestJS behind it, Prisma over PostgreSQL by default, Temporal driving scheduled work and Resend for email notifications.
What you get once it is running is fairly direct.
- Scheduling: queue posts for X, Bluesky, Mastodon, Discord and other platforms, with AI assistance in several places.
- Analytics: measure how published work actually performed.
- Team collaboration: invite members to comment, schedule and exchange posts.
- Automation: a public API, a NodeJS SDK, a custom N8N node, a Make.com integration and an agent CLI.
- Compliance: authentication runs through official platform OAuth flows, and the product never collects, stores or proxies user API keys.
A quick start guide in the documentation covers bringing the project up. Nothing is scraped or automated against a platform's wishes, since users authenticate directly with each service. For anyone running scheduling as one step in a wider automation chain, the API and the N8N, Make.com and Zapier paths matter more than the interface itself.
A self-hosted social media scheduler for agencies, small businesses and creators who want publishing and analytics without per-seat pricing.
Mixpost is a social media management platform you host yourself, built to compose content, schedule it, measure how it performed and coordinate a team around all three. This repository holds Mixpost Lite, the free edition of a product that also sells Pro and Enterprise tiers.
It is distributed as a Laravel package on Packagist and installed into a Laravel application. Contributions follow the PSR-12 coding standard, and the Lite edition is released under the MIT license.
The feature set is aimed at people running several accounts at once.
- Account management: every connected social account is administered from one place rather than a row of browser tabs.
- Queue and calendar: a posting schedule is built once and then visualized on a calendar.
- Post versions: content is tailored per network, with automated follow-up comments on posts that perform well.
- Media library: images, GIFs and videos are stored for reuse, with stock image sources wired in.
- Workspaces: teams get shared spaces for discussing ideas, assigning tasks and watching performance.
- Templates and variables: reusable templates, dynamic text and hashtag groups cut the repetitive typing.
Analytics are reported per platform and limited to whatever each network's API shares, which the project keeps current as those APIs change. Mixpost suits bloggers, solo founders, marketing agencies and in-house teams who would rather pay for a server than a seat. Installation instructions for the Lite edition live in the project documentation.
A self-hosted social media scheduler that publishes natively to twelve networks from one calendar, with an AI copilot and MCP server.
Running several brand accounts usually means a spreadsheet, a pile of native apps, and a scheduler that hands you back to the mobile app for the last step. TryPost puts the whole presence on one calendar and publishes through each platform's official API, so nothing has to be finished somewhere else.
Posts are written once in a multi-platform composer, tailored per network with previews side by side, and dragged around month, week, or day views to reschedule. An AI copilot reads a brand profile of tone, voice, language, and colors on every generation, drafting captions, hooks, full posts, and multi-slide carousels with images.
Supported networks are Instagram, Facebook, LinkedIn, X, TikTok, YouTube, Pinterest, Threads, Bluesky, Mastodon, Telegram, and Discord, and the workspace around them is shaped for agencies.
- Workspaces: each brand, client, or project stays isolated in its own space.
- Collaboration: owner, admin, and member roles, approval flows, and comments with mentions on drafts.
- Asset library: reusable workspace media plus Unsplash and Giphy search built in.
- Repurpose: videos you post outside TryPost replicate automatically to your other networks.
- Analytics: reach and engagement per connected account across every platform.
- API and MCP: a REST API and a first-class MCP server let Claude, Cursor, or ChatGPT draft, schedule, and publish for you.
Self-hosting is free and keeps posts, drafts, and metrics on your own infrastructure under AGPL 3.0, which allows commercial use provided changes to a network service reach its users. A hosted version runs the same product. The interface ships in sixteen languages.
