Automatically scales-to-zero
Requests are so fast, services can shut back down seamlessly between requests — minimizing compute consumption.
Secure by
default
Every Wasm application runs in a secure sandbox — eliminating cross contamination.
Compute less, save more
A lighter, faster, and more efficient model means lower cost and more sustainable for your business and our planet.
We've got you covered.
Not just JavaScript — compile almost any language to Wasm.
Fermyon’s Spin works with mainstream languages like JS/TS, Python, .NET, Rust, and Go. We adhere to the WASI standard, which means dozens of languages that have support for Wasm can be compiled, built and deployed.
Deploy and run for free
No tricks. You can run apps on Fermyon Cloud without having to worry about an expiration date. You can opt into future, paid upgrades later on if you need to.
