Self-hosted cross-posting / multi-posting for social networks — compose once, publish (or schedule) the same content to many channels at once, with a scheduling calendar and isolated client workspaces.
Built on top of Postiz (AGPL-3.0), extended with first-class support for VK and MAX — Russian networks that no mainstream scheduler covers.
The implementation lives in a fork of Postiz:
github.com/wiliam/postiz-app, branch
pubmeboss. Self-host
deployment files (Docker Compose + setup notes) live in deploy/.
Status: VK and MAX providers implemented (customFields paste-token connect flow, no OAuth for either); live end-to-end verification against real accounts is still pending. See docs/PRD.md for the full product spec and docs/providers/ for per-provider detail.
Mainstream schedulers (Buffer, Publer, Publora, Postiz) cover Western platforms well but ignore VK and the new MAX messenger. pubmeboss keeps the polished Western workflow (Instagram, Threads, YouTube, Telegram, …) and adds VK/MAX as publish targets, so one piece of content can be mirrored across all of them.
| Platform | Status |
|---|---|
| Instagram, Threads, YouTube, Telegram | Core — publish from day one |
| VK | Mirror target — provider reworked (community token paste flow); media E2E pending |
| MAX | Mirror target — new provider (MAX Bot API, platform-api2.max.ru); E2E pending |
| X/Twitter, LinkedIn, Facebook, TikTok | Fast-follow (already in Postiz) |
- Cross-post one composition to many channels, with per-channel text overrides
- Scheduling calendar with a job queue, retries, and per-channel status
- Multiple accounts per platform
- Isolated client workspaces
- Public REST API + MCP server (publish from AI assistants)
Analytics and AI assistance (editor / idea generation) are planned for a later phase.
pubmeboss is a light fork of Postiz. New platforms are added as self-contained provider modules on Postiz's provider interface; the rest of the stack (calendar, queue, media, workspaces, MCP) is reused. See docs/PRD.md and docs/providers/.
Self-hosted via Docker Compose (e.g. Dokploy / Coolify). See deploy/README.md and deploy/docker-compose.yaml for the compose stack (Postiz + Temporal), env vars, and the first-user / invite-only bootstrap flow.
