Developer tool names that are actually free to take

25 names, checked against the live registries on 2026-08-08. 21 still have at least one of .com / .ai / .io / .dev open. ✓ click-to-copy.

Dev tools live and die by a memorable name — and .dev exists precisely for them, with far more room than .com. Each name below carries the registry's own answer for four TLDs. Note the pattern: almost every strong name has lost its .com, but .ai / .io / .dev are still open country.
