Code Analyzers

Smart code analysis

Deep analysis helps track down hard-to-find bugs and quality issues. Advanced, highly accurate techniques such as data flow analysis maximize productivity by reducing false positives.

Unique, Industry-Leading Quality Methodology

Leak approach

Get the developers to focus on the code they add or change, instead of looking at the debt that is already in the system. New issues are spotted quickly and can be fixed early, leading to automatic and organic increase in code quality.

Leak approach

Quality gates

Set a policy for shipping code to production, based on a leak approach. This will guarantee that code added and changed will meet the quality requirement and that overall quality of the application increases from version to version.

Quality Gates

Short feedback loop

Increase development team speed and efficiency, reduce team friction and empower developers through rapid issue identification and short resolution timeframes.
