Buffer alternatives: 3 open-source picks
Buffer costs $6/mo — $72 a year. These 3 alternatives replace it for $0, led by Postiz, Mixpost Lite and BrightBean Studio. All 3 are open source. License, stars and last commit checked by hand on 2026-08-10. No trials, no crippled tiers.
The broadest open scheduler here; free means running PostgreSQL, Redis, Temporal and your own platform credentials.

runsyour machine or their cloud
installHosted signup, or the official Docker Compose stack
dataSelf-hosted data spans PostgreSQL, Redis, and Temporal; uploads use local persistent storage or configured object storage such as Cloudflare R2. Hosted data lives in Postiz's cloud.
the catch vs BufferThe software is broad, but self-hosting its PostgreSQL, Redis, Temporal, storage, and OAuth stack is far more operational work than paying Buffer.
setupSelf-hosting is a substantial stack: the docs call for PostgreSQL, Redis, Temporal, persistent storage, a public domain, and each network's OAuth credentials, with 4 vCPU and 8 GB RAM recommended.

A polished single-user scheduler with queues and basic analytics; the serious team features live in the paid edition.
licenseMIT
runsyour server
installDocker Compose; manual Laravel installation is also documented
dataApplication data lives in MySQL or MariaDB, queues and cache in Redis, and media on local disk or configured S3-compatible storage.
the catch vs BufferMixpost Lite replaces Buffer's managed service with a server you must secure, back up, update, and keep connected to changing social APIs.
setupA non-expert needs a server, Docker, a domain with TLS, cron/queue workers, and social-platform application credentials.

A startlingly complete free scheduler: approvals, inbox, analytics, clients, API and MCP, with someone else running the servers.
licenseAGPL-3.0
runsyour machine or their cloud
installHosted signup, or Docker Compose for self-hosting
dataThe hosted service stores application data in BrightBean's infrastructure; self-hosting uses PostgreSQL for application data and server-controlled storage for media, while local development can use SQLite.
the catch vs BufferIts biggest weakness is maturity: a much smaller project and hosted service have less established platform-change coverage and support history than Buffer.
setupThe hosted version is straightforward; self-hosting needs Docker, a public domain, and developer credentials or OAuth apps for the social networks.
