API & Dev Tools
The picks and shovels of software: API platforms, SDKs, testing utilities, CI helpers, and everything that makes shipping code faster or less painful. Developers are ruthless customers, so the tools that survive in this category tend to be genuinely good. Look for generous free tiers and docs that respect your time.
