How to evaluate this category

Choose tools that remove friction more than they add surface area

Developer tools earn their place when they reduce context switching, make debugging clearer, or shorten repeated setup. Extra capability only matters if the team can absorb it without slowing down.

Test whether the tool improves the second and third use, not just the first run.
Look for dependable output, clear docs, and low adoption friction.
Compare collaboration and review impact, especially for shared engineering workflows.

The best developer tools often feel quiet: they disappear into the work instead of demanding a new ritual around every task.
