Buffer is published by Buffer. This page compares only projects with an explicit relationship to it; shared categories alone never create an alternative claim.
Recommended order uses OpenAlternative organic alternatives v4 (version 4). Relationship confidence, category fit, logarithmic popularity, as-of maintenance and freshness, bounded anomaly quarantine, and known-data penalties. Payment is fixed at zero.
A hard constraint removes a Project only when its stored fact is known and conflicts. Unknown facts remain visible, are called out below, and never become a negative claim.

Postiz is a self-hostable scheduler for teams that publish to many networks and do not want to pay per seat for the privilege. It covers planning, drafting, approval, and publishing, with AI assistance for turning one post into per-network variants.
