Pollinations
The cheapest way to bolt generation onto a hobby project, a Discord bot or a classroom demo — a URL is the entire SDK, no key required to start. Do not put anything with an uptime promise on top of it.
Pros
- endpoints are plain GET URLs, callable from any language or a no-code tool
- covers image, text, speech, video, 3D and embeddings from one origin
- MIT licence and a public repository, so the exit path is real
- an MCP server exposes generation directly to Claude and similar assistants
Cons
- the anonymous free API allows one image every 45 seconds and one text answer every 30 seconds per IP
- free-API images carry a small Pollinations logo and use a single model
- support is GitHub issues and Discord, not a company inbox
- the model roster shifts, so outputs are not reproducible over time
