Learn to build on the Fastly platform

Start here

Our documentation provides a range of tutorials and guides to help you get the most out of the Fastly edge cloud platform. If you're new, check out our "start here" page for guided onboarding:

Service types

Fastly offers two types of edge service: highly performant and configurable services powered by Fastly VCL, and next generation Wasm-powered compute@edge services currently in private beta:

Domains and origins

Domains are web addresses that point to your services on Fastly. Origins are web addresses that point to the servers hosting your application.

HTTP and caching

Fastly respects the instructions you provide via HTTP headers such as Cache-Control. But you can also exert much finer-grained control over the way we load and cache your resources.

Content delivery and transformation

As well as serving content loaded from your origin, Fastly can also manipulate that content in useful ways, or even generate content from scratch without loading anything from your origin.

Data storage

Fastly provides key-value stores at the edge that are highly optimized for reads.

Logging and debugging

Observability and debugging tools to help fix problems, test and monitor your Fastly services.
