APIs
APIs tools are for building, testing, and documenting APIs — the kind of work every indie hacker eventually hits and would rather not build from scratch. 6 tools are listed here, each picked and written up individually rather than pulled from an affiliate feed. Apidog is usually the first one people try: design, mock, test, and document your API in one tool instead of stitching together five. Hoppscotch takes a different angle — open-source, runs in a browser tab, and loads instantly — great when you just need to fire a request. And Insomnia is worth a look too: a cleaner, faster API client than Postman if you don't need the enterprise bloat. Every listing below includes the actual tradeoff, not marketing copy, so you can pick based on what you're building instead of what ranks highest in a sponsored roundup elsewhere.
