Postiz vs Buffer
Postiz scores 53 to Buffer's 52 on public evidence for social media posts, and they rank #2 and #3 there. Both are free to start. Numbers below are the same public signals the ranking uses, recomputed nightly — nothing here is sponsored.
Postiz
Self-hostable scheduler for a dozen networks, with AI drafts and a team calendar.
+ Your own instance, your own API keys, no per-channel pricing.
− Self-hosting means you own the OAuth app approvals each network demands.
Buffer
Schedules posts across every network and drafts them from a note with an AI assistant.
+ The free plan is genuinely usable, and the AI drafts read like the account's own voice once fed a few posts.
− Analytics and engagement sit behind the paid tiers.

Which one?
Pick Postiz if

- you want open source — self-host it, read it, fork it
- you need it on api, linux
- a bigger GitHub community matters (39,186 vs 0 stars)
Best for agencies that would rather host than pay per seat.
Pick Buffer if
- you need it on android, chrome-extension, ios
Best for one person keeping several accounts alive.
