The open-source Postiz alternative
GrowSocialelion and Postiz are both AGPL-3.0, self-hostable, and built for AI agents over MCP. The practical differences: Postiz has a wider network list today and metered AI media; GrowSocialelion ships an engagement inbox, per-action approval modes, and free tools whose every number carries a source. Postiz's cloud starts at $29 a month after a 7-day trial.

Postiz vs GrowSocialelion, on the record
| Postiz | GrowSocialelion | |
|---|---|---|
| AI content | AI copilot, AI images and videos, metered per plan | The agent drafts per network, in your voice, from live research |
| Approvals | Share-for-approval preview links with comments | Every agent action is approval-gated: human, semi-auto or autopilot, per action type |
| Inbox / engagement | Not documented | Inbox for replies and mentions on connected networks, in the open-source app today |
| Agent access | API, CLI and MCP server | MCP from day 0; the same publish tool the UI uses |
| Free tools | 243 tool pages, no sourced limits | 500+ free tools; every character limit carries a source and date |
We build GrowSocialelion, so read the table knowing that. Every Postiz fact on this page comes from Postiz's own pages, checked 2026-08-27. If a price changed since, their page wins.
Both sides of the ledger
What Postiz does well
The network list is wide: their docs cover 30+ providers, from the big platforms down to Nostr, Lemmy and WordPress. (source, 2026-08-27)
Agent support is real, not a badge. Public API, a CLI, and a documented MCP server with a tools reference. (source, 2026-08-27)
A large, active open-source project: about 35,000 GitHub stars, with the repo claiming feature parity between self-hosted and cloud. (source, 2026-08-27)
Where Postiz stops
There is no permanent free cloud tier. The trial runs 7 days, then the cheapest plan is $29 a month, and that plan excludes team members. (source, 2026-08-27)
No unified inbox. Neither the homepage nor the docs index documents engagement or reply management from inside the product. (source, 2026-08-27)
Self-hosting means bringing your own provider API credentials for every network, each with its own app-approval process. (source, 2026-08-27)
Who should stay with Postiz
If you need TikTok, Instagram or YouTube publishing this week, stay with Postiz. Those networks are in their connected list now and in our catalog as planned, and a roadmap does not publish posts.
If AI video generation matters to your workflow, Postiz meters it into every cloud plan and we do not generate video at all.
If you want a hosted product today with a credit card and no server, Postiz's cloud is live and ours is still pre-launch. Our honest offer right now is the self-hosted app and the free tools.
This is the comparison we can write with the least spin, because Postiz made the same two big choices we did: open source under the AGPL, and agent access as a first-class interface rather than an afterthought. If you are choosing between the two, you are choosing between two implementations of the same philosophy, and the differences worth your time are concrete.
Postiz went wide: more networks connected today, AI image and video generation metered into each plan, and a mature cloud. We went deep on trust: an inbox so engagement happens where drafting happens, an approval gate on every single agent action rather than a shareable preview link, and a rule that a number the network does not report renders as 'not reported' instead of zero.
Asked before switching
Is Postiz open source?
Yes. Postiz is licensed AGPL-3.0 with the code on GitHub, and self-hosting is free. GrowSocialelion uses the same license, so on openness the two are equals.
Does Postiz have a free plan?
Not a permanent one on the cloud. As of 2026-08-27 their pricing page offers a 7-day trial, then plans from $29 a month. Self-hosting Postiz is free. GrowSocialelion is free to self-host too, and its 500+ online tools are free without an account.
Which supports more social networks?
Postiz, today. Their docs cover 30+ providers. GrowSocialelion publishes to 8 networks now (X, Bluesky, Mastodon, Telegram, Tumblr, Nostr, Lemmy, DEV) with 30 more researched and planned in the catalog.
Do both work with AI agents over MCP?
Yes. Postiz documents an MCP server, CLI and public API. GrowSocialelion shipped its MCP facade from day 0, and the agent's publish tool is the same one the UI calls, behind the same approval gate.
Other alternatives
Try the part that is already free
The hosted app is still pre-launch, so we will not pretend there is a signup. What runs today: the open-source app on your own server, and 500+ free tools that need no account, including character counters whose every limit carries a source, something Postiz's tools do not offer.
