5 Reasons to choose DeepSource over Code Climate
Simpler configuration and smoother workflow integration
Our native integration with GitHub and GitLab requires zero technical support and less than 5 minutes to get started. Simply add a .deepsource.toml file to your repository's root. The quality checks run as part of the code review workflow helping you identify issues directly during pull request and resolve them early, before the code is merged.
Accurate results with fewer false positives
DeepSource’s first class support for Python, Go and Ruby is engineered for less than 5% false positives. You can also customize rules via the dashboard to get better analysis, filter out the noise and focus only on issues that matter.
In-depth analysis to detect complex issues
DeepSource is built to detect potential flaws that can go unchecked during manual reviews along with the usual style and syntax errors. Identify the source of such flaws and fix them during code review to prevent the risk of your code breaking in production.
Informative issue reporting
Every issue flagged by DeepSource is clearly categorized into— security risk, bug risk, anti-pattern, performance issue, style and documentation issue. Each occurrence then is further tagged with issue category (ones mentioned above), location (line number), title and clear description for you to resolve it real quick.
Actively maintained analyzers
We have an in-house team to maintain all our analyzers with new rules, and continuously improve the accuracy of existing rules. All these updates are made available to you by default, without any action from your end.
Developer experience focused UI
Developers use the tool they love, and providing a great experience to them is at the heart of everything we do. The lightweight, easy to use interface provides clear visibility into every essential information— issues detected with detailed description, key metrics such as test coverage, internal & external dependencies as well as the history of analysis runs. All are further complemented with powerful search, sort and filter functionalities to enable you to find, prioritize and fix more issues.
