Advertiser disclosure: iTechGuides is reader-supported. Vendors can pay for top positions in our rankings and for a place on other products' pages, and we may earn a commission when you click some links. Bought places stand at the number bought; this page and our disclosure say so. Paying vendors may get a fuller, more detailed review from our editors, and that review can change their score.

Our review
Pros
  • WebAssembly isolation with Rust, JavaScript, Go, C++, and Python support
  • Streaming request and response bodies for edge-native applications
  • Fastly CLI, Terraform, GitHub Actions, logs, metrics, and KV Store integration
  • Automatic scaling from zero to peak demand
  • Extensive integrations with AWS services and Apache Kafka
  • ZIP, container image, and custom runtime deployment options
Cons
  • Usage-based billing can require separate request and vCPU tracking
  • Runtime support depends on WebAssembly and WASI-compatible languages
  • Designed for edge execution rather than a conventional fixed monthly plan
  • Broader serverless focus than explicitly edge-focused execution
  • Execution duration and other AWS services can add charges
  • Custom domains require API Gateway rather than direct function URLs
