Build with Fastly
Develop and test Fastly VCL and Compute applications, manage services with the Fastly CLI, inspect traffic statistics, and audit Next-Gen WAF rules.
Use these skills in a coding environment that can read your project and run local developer tools.
Install the tools required by your workflow, such as the Fastly CLI, Falco, XVCL, Fastlike, or Viceroy.
Authenticated operations use credentials you configure locally; do not share API keys in chat.
Fastly Fiddle tests upload VCL and request specifications to a public Fastly sandbox.
