Rails Best Practices review
A free, open-source Rails analyzer for configurable code-practice checks and reports.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Rails Best Practices is an open-source command-line tool for analyzing Rails application code and reporting code-quality issues. It is aimed at Rails teams that want to check common practices in models, controllers, views, migrations, mailers, routes, and deployment. Distributed as a Ruby gem, it runs from a Rails app directory and is available for Linux, macOS, and Windows. Its Rails focus makes it more relevant to projects using Rails conventions than to Ruby teams seeking a general-purpose analyzer.
The checks cover Active Record, Mongoid, and MongoMapper, and the tool supports ERB, Haml, Slim, and RABL templates. Teams can choose files and directories for analysis or exclude them, then produce text or HTML reports. A generated YAML configuration allows checks to be selected and some settings customized. In HTML output, editor links are supported for TextMate, Visual Studio Code, Sublime Text, and MacVim; GitHub is also listed as an integration. This combination suits teams that want inspectable findings and control over analysis scope, rather than an automated fix workflow.
Rails Best Practices is free and open source, with self-hosted use through the command line; it has no hosted option. It does not provide security analysis, type checking, or autofix, so it is not a fit for teams that need those capabilities from their Ruby analysis tool. Choose it for Rails-specific practice checks and configurable reports; consider another tool if security-focused scanning or type checking is central to the review process.
