“"Gitroom before, will be renamed to Postiz soon." — gitroom/creator (https://news.ycombinator.com/item?id=41402138)”
You know that feeling when you're juggling five browser tabs to post the same content to Instagram, LinkedIn, TikTok, and Discord on a schedule, while paying $99/month for a tool that caps your channel count or locks analytics behind a higher tier? Buffer and Hootsuite solve the multi-platform problem but charge per seat, per channel, and keep all your data on their servers. Building your own scheduler means recreating OAuth flows for 30 platforms. Postiz tries to collapse all of that into one Docker Compose command.
You deploy Postiz via Docker Compose, which spins up PostgreSQL, Redis, and a Temporal workflow server alongside the app. Temporal handles all async operations — scheduling posts, refreshing OAuth tokens, sending email notifications — as durable workflows that survive crashes and are inspectable via a web UI at port 8080. You connect each social platform via OAuth, then schedule posts through a unified calendar. The 'agentic' layer exposes an MCP server and CLI so external AI agents (Claude, ChatGPT) can drive posting workflows without a browser. Self-hosted and cloud versions share the same codebase per the README — no feature disparity.
If you're a developer or technical founder who manages social media across multiple platforms and won't pay $99/month for Hootsuite, Postiz is built for you — especially if you're comfortable running Docker Compose and want full data control under AGPL-3.0. It also fits agencies self-hosting for clients who want the full feature set without per-seat pricing. It's not a good fit if LinkedIn is a core channel right now (the API integration broke in January 2026 and maintainers closed the fix as 'not planned'), or if you need a single-container deployment — Postiz requires PostgreSQL, Redis, and...
Postiz is worth exploring if you're self-hosting and need feature parity with Buffer/Hootsuite at zero software cost — the 30k stars and sold-out AppSumo lifetime deals signal real community demand. The Temporal-based workflow engine is a genuinely better architecture than cron-based schedulers for reliability. Hold off if LinkedIn is a critical channel: issue #1187 (LinkedIn API deprecated, closed as 'not planned') is an unresolved regression that signals what a 1–10 person bootstrapped team prioritizes when platform APIs break. The AGPL-3.0 license also requires a legal review before you build a commercial product on top of it.
