Check the pricing path
Look for a free plan or a free trial before committing. Free, freemium and paid pricing models appear among these tools.
Published starting prices for paid plans include $18 per user per month for Codacy with annual billing and €18 per month for CodeScene with annual billing.
Match your working platform
These tools are available via Linux, Windows, macOS, APIs, extensions or the web. Choose a delivery method that fits your development setup.
An API or extension may suit an existing workflow, while a web tool can provide browser access. Check the platform information for the tool you are considering.
Compare the measurements
The directory compares complexity metrics and hotspot detection. Review which measurements matter for the codebase you need to understand.
Historical trends can reveal changes in complexity over time. Pull-request gates can check proposed changes during review.
