Benefits

Execute code faster

Compute@Edge provides a 100x faster code execution startup time than other serverless solutions. Run your code on hundreds of servers located around the world simultaneously. There are no cold starts or roundtrip delays — just fast, always-on computing.

Enhance security and reliability

Operating within microseconds, our isolation technology helps protect you from side-channel attacks and diminishes resource contention while offering consistent performance you can count on. By creating and destroying a sandbox for each request that comes through the platform, we limit the blast radius of buggy code or configuration mistakes from other users and can reduce the attack surface area.

Build exceptional user experiences

Better end user experiences are at the forefront of digital transformation. Write, deploy, and test your code on the Fastly edge using a powerful local development and debugging environment. From there, we manage everything required to scale it instantly and globally, as close to your end users as possible.

Leverage familiar tools and languages

Developer experience and intuitive tool sets matter. With Compute@Edge, you can program in familiar languages, like Rust and JavaScript, port your code across cloud providers, and get an up-to-the-second view of your services. Plus, Compute@Edge seamlessly integrates into your existing tech stack.

A Forrester New Wave™ Leader 2021

With an execution speed 100 times faster than other solutions and unmatched isolation technology security, Compute@Edge was named a Leader in the Forrester New Wave: Edge Development Platforms report.

Tooling

Debug quickly with live log tailing

Stream custom log messages within a terminal or test applications running on Compute@Edge to identify program errors and quickly debug your code without having to use a third-party service.

Trace individual end-user requests

For customers building with Compute@Edge we tag individual end-user requests with unique identifiers and maintain request tracing parameters by tracking when users enter and exit our serverless platform.
