Our verdict on haml-lint
haml-lint is an open-source Ruby tool that analyzes Haml templates and reports style and quality issues. It is aimed at solo developers and small Ruby teams maintaining Haml-based projects, particularly those that want template checks during development. Distributed as a Ruby gem, it can run locally across Linux, macOS, and Windows environments, with self-hosted deployment for teams that keep development tooling in-house.
Its main strength is focused, configurable linting rather than template rendering. Teams can adjust linters to match project conventions, then invoke checks from the command line or add them to Ruby development workflows. That makes haml-lint a practical fit for repositories where Haml quality checks need to be repeatable and close to the code. The narrow scope can also make adoption clearer: teams are evaluating template style and quality rules, not adopting a broader rendering or application platform.
The trade-off is its deliberately limited focus. Haml is the supported template language, and the published feature set does not include security analysis or AI capabilities. Deployment is self-hosted, so teams manage how the Ruby gem and command-line checks fit into their own development process. Choose haml-lint when a Ruby project needs configurable Haml linting without a license cost. Consider a broader template-engine or code-analysis product when one tool must cover multiple template languages, hosted administration, or security-focused analysis.
