The toolkit your AI can't build for you
When Cursor generates a 500-line JSON response and something breaks, you need tools that work instantly. No install, no config — just paste and debug.
Sound familiar?
You're vibe coding with Cursor, Copilot, or Claude and something doesn't work. Here's what happens next.
Your AI generated JSON but it’s invalid
JSON Formatter catches the syntax error in seconds. Paste the output, see exactly where the bracket is missing.
Open JSON Formatter→The API token isn’t working
JWT Decoder shows it expired 3 hours ago. No more guessing why your auth calls return 401.
Open JWT Decoder→Two config versions and something broke
Diff Checker shows exactly what changed between the working version and the broken one.
Open Diff Checker→Works alongside your AI workflow
These tools don't replace Cursor, Copilot, Claude, or ChatGPT. They fill the gaps your AI can't.
No context-switching
Keep your AI chat open. Open a tool in another tab. Paste, debug, go back. Your flow stays intact.
Browser-based, zero install
No npm packages to add, no VS Code extensions to configure, no CLI tools to learn. Just open and use.
Instant results
Every tool runs client-side in your browser. No server round-trips, no loading spinners, no waiting.
