Bryan Blair Toosli

As a developer, I keep a handful of utilities bookmarked for daily debugging and quick tasks. Toosli replaced most of them with one clean site. Dev tools I use regularly: ⚡ JSON Formatter & Validator — format, minify, fix broken JSON ⚡ Base64 Encoder/Decoder — encode/decode text and data ⚡ URL Encoder/Decoder — percent-encoding made easy ⚡ Regex Tester — live match highlighting ⚡ JWT Decoder — inspect header, payload & expiry ⚡ Hash Generator — MD5, SHA-1, SHA-256, SHA-512 ⚡ Timestamp Converter — Unix epoch ↔ human date ⚡ UUID Generator — instant v4 UUIDs ⚡ CSV to JSON Converter — both directions ⚡ Text Diff Checker — compare two snippets side by side Everything runs client-side in JavaScript. No API keys, no rate limits, no sending sensitive tokens to a third-party server. Bookmark it for your next debugging session: https://toosli.com
