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.
Rust, Go, Python, JavaScript, .NET, Ruby, C#
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.
Quotes
“We've been able to take a Kubernetes batch process of tens of thousands of orders and cut the compute cost by 60%, without trading off performance”
Kai Walter
Distinguished Architect, ZEISS Group
“It enabled us to build holistic service components, including smart contracts, and integrated a zero trust architecture with confidence that third-party code wouldn't introduce risk in such a critical environment”
PJ Łaszkowicz
Technical Director, Omnijar
“Fermyon not only reduces complexity but also continues to address enterprise cloud computing pain points head-on while also considering the growing demand for increased profitability and productivity.”
Paul Nashawaty
Principal Analyst at The Futurum Group
“It took me 13 lines of code and 2 commands (spin build, spin cloud deploy) to build and deploy a simple 'chatGPT like' app with Fermyon”
Sébastien Blanc
