access to auth cloud storage databases and ai claude gpt gemini and 500 other models with no api keys and no infrastructure setup the entire library is a single script tag or the heyputer puter js npm module this is also what makes puter js work so well as the backend for ai generated apps there is nothing to configure no keys to obtain no servers to provision no sdk to initialize ai coding tools and platforms like claude code codex opencode lovable and replit can generate complete working apps in a single shot with puter js the api is small and consistent enough for language models to use correctly and the full reference is published as llms txt so ai tools can read it in one request https super magical website com openai cloud storage claude gemini nosql script src https js puter com v2 script hosting api auth ocr networking text to speech additionally with puter js you as the developer pay nothing since each user of your app covers their own cloud and ai usage whether your app has 1 user or 1 million users it costs you zero to run puter js gives you infinitely scalable infrastructure completely free puter js is powered by puter the open source cloud operating system with a
