A secure, user-scoped backend for your CodePens, micro-apps, and widgets. AES-256 encryption at rest, no configuration, instant availability.
I loved using CodePen to build small utilities and quick tools for myself. It was the fastest way to turn an idea into something usable. But every time I built something useful, I ran into the same problem.
None of my tools could store data permanently. As soon as I switched browsers, cleared storage, or opened the tool on another device, everything was gone. There was no simple way to save data or make it accessible across browsers without setting up a full backend, which felt heavy and unnecessary for small projects.
I didn’t need a complex system. I just needed a simple, secure way to store some data.
That’s why I built Stashlet. It’s a lightweight JSON storage service designed for builders who build small utilities and demos. It provides persistent storage without the overhead of managing servers, making it easy to give even the smallest projects a reliable backend.
Data is encrypted at-rest using AES-256. We store it securely, and only those with the user's secret can decrypt it.
Register in seconds. No email, no auth, just a unique App ID and Secret. Perfect for prototypes and hackathons.
Store up to 64KB per user and 1,024 users per app. Perfect for state-heavy micro-apps and complex configurations.
