About DevTools Box | Browser-Based Developer Tools

Why this exists

Developers reach for small tools throughout the day: formatting JSON, decoding Base64, generating UUIDs, computing hashes, testing regexes, and comparing text. DevTools Box keeps those tasks in one focused workspace.

The goal is simple: open a tool, paste input, get a result, copy it, and move on. No account setup, no dashboard, and no extra steps around the task.
