Postiz
Self-hosted social scheduler for 30+ networks with a public API, an in-repo MCP server, and an agent CLI.
Self-hosted · Standard: $29 per month · Team: $39 per month · Pro: $49 per month · Ultimate: $99 per month
- I run social for a few brands and want a Buffer I own, with my agent posting through an API
- I need one calendar that publishes to a dozen networks and I do not want per-channel pricing
- Pull analytics
- Team comments and collaboration
- Buy or exchange posts in the marketplace
1 more job is undetermined.
- AGPL-3.0: network use of a modified copy triggers source disclosure
- Every network needs your own developer app; Meta and TikTok apps require platform review before you can post for other accounts
- Public API is rate limited to 90 create-post calls per hour by default; self-hosters raise it with API_LIMIT
- On the hosted service the API is on paid plans only
- Requires PostgreSQL, Redis, and Temporal; the stack is heavier than a single container
TryPost
Open-source social scheduler for 12 networks with a first-class MCP server and REST API.
Self-hosted · Cloud: $12 per month
- I want Claude or Cursor to draft and schedule my week of posts through MCP, on a scheduler I host
- I run several client brands and need workspaces and approvals without per-seat pricing
- Run approval workflows and comments
- Build automations (RSS, webhooks, AI generation)
- AGPL-3.0
- MCP accepts only OAuth 2.1 tokens with the mcp:use scope; dashboard API keys do not work against the MCP endpoint
- Each network needs your own developer app and, for Meta and TikTok, platform review
- 579 stars and a 2026 launch: younger and less battle-tested than Postiz
- Needs Redis and a websocket server (Reverb) in addition to PHP and a database
BrightBean Studio
Free, no-tier social media manager for agencies, with an in-repo MCP app, API, and agent skill.
Free
- I run social for many clients and want approvals and a client portal without paying per workspace
- I want a free hosted scheduler my agent can post through today, with the option to self-host later
- Client approves through a magic-link portal
5 more jobs are undetermined.
- AGPL-3.0
- INTELLIGENCE_INTERNAL_URL and STUDIO_SHARED_SECRET point at a separate intelligence service; check whether self-hosters get sentiment analysis without it
- Bring your own developer credentials for every platform; Meta and TikTok apps need review
- 2FA is on the roadmap, not shipped
- MCP tool list was not read; Reach for approvals, inbox, analytics, and media is unverified
Mixpost
MIT Laravel social scheduler; the free Lite edition has no API, so agents can only reach the paid tiers.
Lite · Pro: $299 once · Enterprise: $1,199 once
- I only post to a Facebook Page, X, and Mastodon and want a clean scheduler I own under MIT
- I already run Laravel and want scheduling inside my own app rather than a separate service
- Schedule posts to Facebook Pages, X, and Mastodon (Lite networks)
- Publish to Instagram
- Publish to TikTok
- Publish to YouTube
- Manage the media library
- Use post templates, variables, and hashtag groups
- Read analytics
- Run team workspaces
- The free edition has no API, so there is no agent path into Lite short of screen control; the wrapper only works against Pro or Enterprise
- Lite supports only Facebook Pages, X, and Mastodon; Instagram, TikTok, YouTube, LinkedIn, and the rest are paid
- Last push to the Lite repo was 2026-03-16, two weeks inside the activity window; Pro moves faster
- Pro and Enterprise source may be modified for internal use only; they are not open
- Requires a public domain before install
