HitboxSmith

HitboxSmith is a hitbox and hurtbox editor for 2D game developers. Paint hitboxes and hurtboxes directly on your sprite frames, scrub the timeline with onion skinning, and get a live frame-data table built on real fighting-game conventions: startup, active, and recovery frames, advantage on hit and on block, plus meaty values for late hits.

This free demo is a great way to try the workflow before you buy. Demo limits: up to 8 frames, 1 move, and JSON export only.
