Every tool1783 tools
Built like a real tool
Not a form you fill out once. The parts you'd expect from something you keep open in a tab.
Nothing leaves your browser
Every tool runs client-side against a static export with zero backend. Open the network tab while you use one, there's nothing to watch.
Chain tools together
Send one tool's output straight into the next, JSON Formatter into JSON to CSV, no copy-paste round trip required.
Updates as you type
No convert button to hunt for. Results recompute live while you type, every time.
Favorites, remembered
Star the tools you reach for daily and jump back into your last few. Saved locally on your device, never synced to a server.
Building a SaaS?
Skip the boilerplate these tools are built with.
Staaarter is the same production-ready Next.js stack, auth, billing, admin, SEO, and security, wired together so you can ship this weekend instead of next quarter.
