+                MyDevTools is the unified developer toolkit that brings together everything you need: a powerful SQL, NoSQL (MongoDB), and Redis database client alongside 60+ utility tools. Stop switching between tabs and apps—format JSON, test APIs, decode JWTs, build regexes, generate UUIDs, and manage databases all in one workspace.

+                Privacy-first architecture means your data is processed in your browser whenever possible. Sensitive credentials are AES-256 encrypted before sync. Whether you're testing REST endpoints, debugging database queries, or working with cryptographic tools, everything runs with zero-knowledge encryption. Self-host for free or use our managed cloud with paid subscription.

Compare MyDevTools to Postman (API client alternative), DBeaver (database GUI), single-purpose online tools, and other dev tool platforms—we unify what others scatter across 20 tabs.
