Why it ranks #1
The clear open-source category leader at roughly 34k GitHub stars, an order of magnitude ahead of alternatives and the most frequently cited self-hosted Buffer/Hootsuite replacement.Here is the catch
self-hosting and OAuth app setup are operationally demanding
social-network API changes can break connectors
AGPL licensing may constrain proprietary redistribution
Does this well
widest network coverage among actively maintained open schedulers
modern interface and strong development momentum
self-hosting avoids per-channel SaaS fees

- 3Socioboard 5.0A veteran open-source social platform (~1.5k stars) with CRM, analytics and approval flows across ~9 networks. Stars accrued over many years but the codebase is older and recent maintenance is unclear — treat as legacy.
- 4TryPostA newer full self-hosted app (~424 stars, AGPL-3.0) with an AI copilot and native publishing to 12 networks, positioned as a Postiz-style alternative. Small but active; a genuine functional app rather than a plugin.
