Best developer tools by category
55 lists, one per category with at least four reviewed tools. Each pick shows its verdict and the Catch.
Order: free and open source first, then hosted products with a real free tier, then paid-led; catalog order inside each group, with quiet or archived repos last. Not a score, and no tool pays for its place.
