nginx-lint

nginx-lint is a linter for nginx configuration files that catches security issues, best practices violations, and syntax errors. It includes over 30 built-in rules, an autofix feature to correct problems automatically, and a browser-based Web UI for interactive linting. The tool supports partial config files with context awareness, customizable rules via .nginx-lint.toml, and a WASM plugin system for extending functionality with custom rules written in Rust.

Designed for DevOps engineers and teams managing nginx deployments, nginx-lint integrates into CI/CD pipelines with JSON output and GitHub Actions support. It's available as a command-line tool, Docker image, and interactive web interface. The maker says it was built with Claude Code.
