Postiz
An open-source social scheduler you can self-host for free or pay for as a hosted cloud service.
What it actually does
Postiz is an AGPL open-source scheduler covering 20+ platforms. You can run it yourself with Docker on a cheap VPS at no software cost, or subscribe to the hosted cloud tiers to skip the setup.
Every paid tier includes an API, webhooks, analytics and an AI copilot; post volume is capped on the entry Standard tier (about 400 posts/month) and only becomes unlimited from the Team tier up. Cloud tiers scale by channel count from 5 up to 100 channels.
The tradeoff for self-hosting is operational: you must register and maintain your own OAuth app credentials for every social platform, which is a meaningful one-time setup effort.

- Open source (AGPL): self-host for $0 software cost on a cheap VPS if you know Docker
- API, webhooks and analytics on every paid tier (posts capped at ~400/mo on Standard, unlimited from Team up)
- AI copilot, AI media generation and 20+ supported platforms
- Cloud Standard at $29/mo covers only 5 channels and caps posts at ~400/mo, and AI image-generation allowances are limited on that tier
- Self-hosting means registering and maintaining OAuth credentials for every platform yourself
- Younger project than incumbents, so team-collaboration depth is thinner than Mixpost or Buffer
Pay less for it
4 ways foundAGPL open source is $0 software cost; you pay only for a ~$5/mo VPS
Cloud tiers offer roughly 20% off with a yearly discount over monthly
Stay on Standard if you have 5 or fewer channels rather than jumping to Team/Pro
Mixpost — Also open source and self-hostable, with a one-time Pro license instead of a monthly cloud fee if you want to avoid subscriptions

Is it the right tool for you
- You are technical and will self-host for a full scheduler at VPS cost
- You want an API and webhooks on paid tiers
- You post across many niche platforms (20+ supported)
- You do not want to maintain OAuth apps or a server → use Buffer or Post Bridge
- You only need 5 channels and dislike the Standard post cap → use Buffer per-channel
