Serverless Compute Environment


Application Programming Interface (API) 

Programmatically interact with Compute@Edge and integrate Fastly into your existing workflows.

Terraform support

Treat Fastly infrastructure as code. Since our product and platform design allows us to act as an integrated part of your tech stack, you benefit from being able to rapidly program, configure, and provision infrastructure.

Command Line Interface (CLI) 

Program, build, and deploy apps with a workflow so seamless that we use it ourselves.

WebAssembly System Interface (WASI)

Write to a standard format across operating systems so you don’t have to rely solely on working through browsers. WASI delivers the benefits of WebAssembly and the web to more users, more places, and on more devices.


Free yourself from the constraints of serverless computing by using WebAssembly supported languages. Compute@Edge supports two languages today, Rust and AssemblyScript (beta), with more to come in the future.

Edge data

Caching platform 

Cache the output of commonly executed logic so you can fulfill future requests for the same information faster. 


Store and use key value pairs at the edge of our network, for quick access to data compared to fetching it from the core cloud.



Get a real-time and customizable view into your services so you can find and fix issues faster. Stream this data to more than 27 logging supported endpoints right from the Compute@Edge CLI. 


We offer real-time, historical, and customizable observability via stats that you can tailor to your specific needs. Leverage stats like CPU and RAM utilization to simplify your workflows and streamline the way you work with Compute@Edge. 


Export performance and tracing data to a third-party system using industry standard tools. And since you can use this data to enhance your business processes, like assigning arbitrary values to metrics, you can do things like measure the revenue impact of an outage or error.
