About Scratchpad
A local snippet store for the throwaway text every developer accumulates — JSON samples, regex patterns, JWT examples, code one-liners. Stored in IndexedDB on this device only; nothing syncs, nothing uploads. The Smart Paste chip auto-detects JSON, JWT, Base64, hash, URL and offers to open the matching tool with the content pre-populated.
- No uploads
- Browser-only
- Works offline
- 100% free
How it works
- 1
Create a snippet
Click New (or press Alt + N). Give it a name and start typing.
- 2
Auto-save
Drafts persist after 800 ms of idle typing, on blur, and on tab close — you never lose work.

Smart route
Paste JSON? Paste a JWT? A Smart Paste chip surfaces above the editor with a one-click jump to the right SnapToolz tool.

Browse allFrequently asked questions
Are my files uploaded to a server?
No. Every tool on SnapToolz runs entirely inside your browser using JavaScript and WebAssembly. Your file is read locally, processed in memory, and the result is offered as a download. Nothing is sent to a server — there isn't one to send to.
Do snippets sync between my devices?
No. Everything lives in this browser's IndexedDB. Use Export → save the JSON file → Import on another browser if you want to move snippets manually. We don't run any sync server.
Can I store passwords or API keys here?
You CAN — the data never leaves your device — but a password manager is still the right tool for credentials. The scratchpad is meant for code shape and structure, not secrets.
What happens when I clear my browser data?
Snippets are wiped along with everything else (this is the same risk that applies to localStorage and cookies). For long-term storage of important snippets, use the Export button to keep a JSON backup.
Does it work offline?
Yes. SnapToolz is a Progressive Web App. After your first visit, the app is cached on your device and every tool keeps working without an internet connection.
Is SnapToolz free?
Yes — every tool is 100% free with no sign-up, no watermark, no hidden tier. The whole platform is open source and we have no plan to gate features.
