Free AI tools for social media posts
Postiz is the strongest tool for social media posts you can use without paying, at 53/100. What you get for nothing: AGPL; self-host free, or pay for their hosting. 4 of the 8 tools tracked for this job have a free tier, an open-source licence, or are free outright. The highest-scoring tool overall is Later (60), which does not qualify: The grid preview is the right interface for anything visual-first.
Same evidence score as the ranking — GitHub stars, Hacker News mentions, Wikipedia readership, release activity, free access — recomputed nightly, never sold. See all 8 tools for social media posts.
Top 3
evidence / 100
+ Your own instance, your own API keys, no per-channel pricing.
− Self-hosting means you own the OAuth app approvals each network demands.
+ 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.
+ Writes the copy and schedules the post from the same place.
− Jack of all trades - the design side is thinner than Canva.
All 4, side by side
| Tool | Score | Pricing | What you get free | Platforms |
|---|---|---|---|---|
| Postiz | 53 | Open source | AGPL; self-host free, or pay for their hosting | web, linux, api |
| Buffer | 52 | Free tier | Free plan for three channels; paid per channel | web, ios, android, chrome-extension |
| Simplified | 49 | Free tier | Free tier with limits; paid per seat | web, ios, android |
 Predis.ai | 9 | Free tier | A few free posts a month; paid by post volume | web, api |
A free tier counts, and so does an open-source licence you can self-host — both are in the table, so a tool that is only free for a trial is not here.
