Finally the promise of true sustainable serverless cloud computing is here with Fermyon’s Cloud offering — a platform that allows me to use almost any language, is incredibly easy to use and blazingly fast.”
— Federico Dionisi
Develop serverless WebAssembly apps with Spin
Create, build, test, and deploy an app in just a few minutes.
Spin is the developer tool for building WebAssembly microservices and web applications
Do more, faster. Pick your favorite language and dive into the important part using Spin's serverless framework. Connect your application to Redis, PostgreSQL, and other data services. And skip the boilerplate.
Three commands are all you need
Keep the development loop simple. Create a project with 'spin new'. Build it with 'spin build'. And test it locally with 'spin up'.
See it in action on the Cloud
Ready for production? Pushing to the Fermyon Cloud is only a 'spin deploy' away.

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.
