An open-source API client that stores collections as plain-text files in your repository, designed as a privacy-focused alternative to Postman.
Why it is useful
Stores API collections as readable files in your git repository rather than in a cloud account — meaning your API definitions are version-controlled alongside your code and never uploaded to a third-party server. The UI is clean and modern enough to be competitive with Postman for daily use. For teams concerned about API secrets being stored in Postman's cloud sync, it is the most practical alternative.
