Post Bridge alternatives: 3 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.
Más de veintiocho canales, API, MCP y CLI; cobertura amplia a cambio de un stack de implementación amplio.
licenseAGPL-3.0+
runsyour machine or their cloud
installHosted signup, or Docker Compose for self-hosting.
enginesOptional AI/media features connect to OpenAI, ElevenLabs, fal.ai, Tavily, KieAI and Transloadit.
dataPostgreSQL holds application data; Redis and Temporal support jobs; media is stored locally or in Cloudflare R2/S3-compatible storage.
the catch vs Post BridgePostiz's broad API and MCP coverage comes with PostgreSQL, Redis, Temporal, storage and social credentials to operate.
setupHosted use is straightforward; self-hosting requires Docker, social OAuth apps, and a PostgreSQL, Redis and Temporal stack.

Publicación amplia, REST, MCP y conveniencia alojada sin complicaciones; la respuesta más cercana que no te entrega una base de datos.
licenseAGPL-3.0
runsyour machine or their cloud
installHosted signup, or clone the repository and deploy with Docker Compose or a supported PaaS.
enginesNo model is bundled; its REST API and MCP server connect external agents such as Claude Desktop/Code, Cursor or custom clients.
dataHosted data lives in BrightBean's cloud; self-hosted data uses PostgreSQL 16+ with media on local disk or S3-compatible storage.
the catch vs Post BridgeBrightBean does not document the same exact network coverage or managed API/MCP reliability guarantees as Post Bridge.
setupConnecting social networks requires first-party platform developer/OAuth credentials; self-hosting also requires Docker or a PaaS.

Publicación cruzada en doce redes con REST y MCP; opera el servidor y aporta tus propias credenciales de plataforma.
licenseAGPL-3.0
runsyour machine or their cloud
installHosted signup, or production Docker Compose; a bare-metal installation is also documented.
enginesAI writing can use OpenAI or an OpenAI-compatible endpoint; the deployment template also exposes Anthropic and Gemini keys.
dataPostgreSQL or MySQL stores app data, Redis handles queues/cache, and media is local or S3-compatible storage.
the catch vs Post BridgeTryPost covers twelve networks rather than every major Post Bridge destination and makes you run the API, jobs and storage yourself.
setupSelf-hosting needs a SQL database, Redis, media storage, and separate developer credentials for each social platform.

The hosted product ships with OAuth apps that Meta, TikTok, YouTube, Pinterest, and Google have already put through business verification and app review, so connecting Instagram or TikTok is a click instead of a multi-week developer-app process you may not qualify for solo. It also absorbs constant API and policy churn, per-platform video specs, and token expiry, and exposes an API plus MCP server so your coding agent can schedule posts through it rather than you rebuilding and maintaining the poster yourself. If none of that applies to you, any pick above saves $348 a year.
Is there a free alternative to Post Bridge?
Yes: Postiz, BrightBean Studio, TryPost. 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 Post Bridge?
Our verdict is PARCIAL. The core loop (compose, queue, cron tick, publish) is one-shottable for networks with open APIs like Bluesky, Mastodon, and Telegram. What you cannot one-shot is the reason Post Bridge exists: one-click posting to TikTok, Instagram, YouTube, Facebook, Threads, Pinterest, LinkedIn, and Google Business Profile. Those APIs are approval-gated behind Meta App Review, TikTok's Content Posting API, YouTube quota, and business verification, which as an individual you often can't even qualify for. On top of that sits per-platform video transcoding, constant token-refresh babysitting, and an API plus MCP server so an agent can post for you. You can vibecode a personal cross-poster for the open networks in a sitting; you cannot vibecode the approvals. If you'd rather build, the exact one-shot prompt is free at puedovibecodearlo.app/post-bridge.
