About
Why We Built ToolMight
As developers, we constantly paste sensitive data—API keys, JWT tokens, JSON payloads, config files—into random online tools. Most of them silently upload your input to remote servers. That's a real security risk.
Every tool, builder, and visualizer on ToolMight runs 100% inside your browser. Nothing is uploaded, logged, or transmitted. It's as private as running software on your own machine.
Is my data secure?
All processing runs locally via client-side JavaScript. No server, database, or cloud service ever sees your input—not even ToolMight's.
Does it work offline?
Yes. ToolMight is a PWA. Once loaded, the entire suite is cached in your browser and works without an internet connection.
Why is it free?
No backend servers means near-zero operating costs. We cover them with non-intrusive ads and pass the savings to you.
Are my settings saved?
Yes. Editor themes, layout preferences, and slider positions persist in localStorage across sessions with no account required.
