Buffer alternatives: 8 free & open-source picks
Curated, verified, and actually free. No trials, no crippled tiers. Star counts and last-activity dates checked by hand, not scraped and forgotten.
ZombieThe broadest open scheduler here; free means running PostgreSQL, Redis, Temporal and your own platform credentials.
licenseAGPL-3.0+
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.
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.

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.
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.
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.

Six networks, a visual editor and a thousand scheduled posts a month; analytics and team workflow are not invited.

enginesAdobe Firefly powers generative text and image features; Adobe does not publish a complete backend-model list.
dataDesigns, media, drafts, and scheduled-post metadata live in Adobe's cloud; connected social networks receive the published content, and the internal storage format is not disclosed.
vs BufferIt does not replace Buffer's dedicated community inbox or channel-focused advanced analytics, so engagement and performance review remain shallower.
setupEach social profile needs OAuth authorization, and Adobe says scheduler connections expire after 60 days and must be reconnected.

They pay because social APIs break and scheduling must be reliable. If none of that applies to you, any pick above saves $72 a year.
Is there a free alternative to Buffer?
Yes: Postiz, Mixpost Lite, BrightBean Studio and 5 more. Every tool on this page is either open source or genuinely free to use long-term: no trials, no crippled tiers.
Should I just build my own Buffer?
Our verdict is KINDA. Posting to one or two APIs is easy, but maintaining social platform auth, queues, previews, analytics, and API-policy compliance is real ongoing work. If you'd rather build, the exact one-shot prompt is free at canivibecodeit.com/buffer.
