About

DevLens is a fast, offline developer multi-tool in your toolbar. Every tool runs 100% in your browser — your data never leaves your machine and the core tools make no network calls.

Tools:
• JSON — beautify, minify, validate (with error position)
• JWT — decode header & payload, see expiry at a glance
• Base64 — encode/decode (standard & URL-safe)
• URL — encode/decode + parse query strings
• Hash — SHA-1, SHA-256, SHA-512
• UUID — generate v4 identifiers
• Timestamp — convert Unix ⇄ ISO 8601
• Diff — quick line-by-line comparison

No accounts, no content tracking. Free to use, with an optional one-time Pro upgrade that unlocks JWT, hashing, and diff. Built for developers who want everyday encode/decode/format utilities one click away — without pasting sensitive data into random websites.
