About trysandbox.io

trysandbox.io is a free collection of everyday generators and developer utilities — QR codes, barcodes, passwords, hashes, CSS effects, JSON and config file builders, fake data and much more. Everything is one click away, with no signup wall and no paywall.

Every tool is written in JavaScript and executed locally on your device. When you generate a password or paste a JWT, that value never leaves the page: there is no upload, no server-side processing and no database. You can even disconnect from the internet after the page loads and most tools keep working.

trysandbox.io is built and maintained by Ambitionmarketing.io. The site is supported by unobtrusive advertising so the tools can stay free for everyone.
