We hash the visible text on every check, so a redesign registers and a rotating advert does not. An app that has not changed in a long time is not necessarily abandoned — but it is a fact worth knowing before you depend on it.

What it does

Puter.js is a JavaScript backend for AI-built apps covering auth, cloud storage, a NoSQL database, an AI gateway, serverless workers, peer communication, and static hosting. It is described as serverless and keyless, with 500+ models from OpenAI, Claude, Gemini, Grok, and others. A code playground and copy-paste prompts are on the site.
