A lightweight browser toolkit for REST, GraphQL and WebSocket testing, local collection runs, response-variable chaining, Postman/OpenAPI imports, PDF optimization, JSON-to-TypeScript/Go/Python generation and everyday converters. PDFs stay local. API credentials are not stored or team-synchronized.
Hi Product Hunt! I built 101Tool because routine development work kept sending me between a heavy API client and many single-purpose converter sites. I wanted one fast place that opens instantly, works without an account, and is transparent about data handling.
The API Studio now supports REST, GraphQL and WebSocket workflows, multiple request tabs, local collection runs, variables and imports. The same site includes local-first PDF optimization, typed-code generation and common converters.
I would love feedback on the request workflow, collection runner and which missing feature would make you return regularly. Thanks for trying it!
Report
Love the local-first stance on PDFs and credentials, that alone makes me want to try it. One thing I'd love to see is a way to save environment-specific variables (like staging vs prod base URLs and tokens) and switch between them with a dropdown, so I don't have to manually edit values when moving between clients. Would make the collection runs feel much closer to Postman without giving up the privacy angle.
