About:
Falco is a specialized VCL parser and linter designed specifically for Fastly's edge computing platform. It validates VCL syntax and configuration against Fastly's unique requirements and best practices. The tool helps developers catch errors early and ensure their edge configurations are optimized for performance and reliability.
Key Features:
  • Fastly-specific VCL validation and linting
  • Real-time syntax error detection
  • Best practice enforcement for edge configurations
  • Fast parsing with clear error messages
Use Cases:
  • Validating VCL configurations before deploying to Fastly
  • CI/CD pipeline integration for edge configuration testing
  • Learning Fastly VCL syntax and best practices
Alternatives:
  • vcl-validate – Generic VCL validator without Fastly-specific optimizations
  • standard-vcl-parser – Basic parser lacking Fastly edge-specific rules
