Look what you can build for free.
This whole site is a Therapy app — interactive, with real data and live notebooks — built in GitHub and hosted on the edge by Snapshot. No server. No bill.
Interactive (WASM)
Real Julia notebooks compiled to WebAssembly, running entirely in the visitor's browser.
Real data, free
A live database with sign-in and persistence — straight from a static site, no backend to run.
On the edge
Served from Cloudflare's global edge. Fast everywhere, scales to zero, costs nothing.
Just a GitHub repo
Push your code; Snapshot builds and publishes it. The exact stack that powers Snapshot itself.
Everything here is static — and yet…
There's no application server anywhere. The pages are plain HTML built by Therapy. The interactivity is WebAssembly. The database calls go straight from your browser to a free edge database, protected by row-level security. That's the whole trick — and it's the same way the Snapshot dashboard works.
