Why Boring?
Because the best tools are the ones that get out of your way
Your Data Stays Yours
Everything runs locally in your browser. No server uploads, no logging, no tracking. Perfect for handling sensitive tokens, API keys, and production data.
Zero Friction
No accounts, no API keys, no rate limits. Just open and use. Bookmark it, add it to your dev toolbar, and access it instantly whenever you need it.
Built for Developers
No bloated features, no unnecessary complexity. Each tool does one thing well. Clean interfaces that focus on your workflow, not on advertising or upsells.
