Free developer tools that respect your privacy
Small, fast utilities that run entirely in your browser. No accounts, no ads tracking you, and your data is never uploaded to a server.
Unix Timestamp Converter
Convert epoch ↔ human-readable dates, in any timezone, seconds or milliseconds.
JWT Decoder
Decode a JSON Web Token's header and payload. Inspect claims and expiry — locally.
UUID Generator
Generate v4 (random) and v7 (time-ordered) UUIDs in bulk. Copy in one click.
Why Toolbit?
Private by design. Many online tools quietly send your tokens, timestamps, or data to a server. Toolbit does the computation in your browser with JavaScript — open the network tab and you'll see nothing leaves the page.
Fast and focused. Each tool is a single, lightweight page that loads instantly. No bloated frameworks, no pop-ups, no login walls.
Correct. These are the kinds of tools where details matter — timezones, leading zeros, token expiry. We sweat them.
