What does Sider Scan do?

By running Sider Scan, you can detect, fix and monitor risks to your code that happen due to code duplication.

Locates hidden duplicates

Sider Scan uses a proprietary algorithm developed in-house to find duplicate code with maximum speed. It then uses its comparison engine to quickly determine the quality of duplicates.

Organises and assesses risk

Sider Scan organises found issues and duplicates, and then provides prioritisation based on the risk of each issue.

Reports new duplicates

When Sider Scan analyzes code over an extended period of time, any changes made in the code will be tracked, and problematic changes will be part of the analysis results. Any new issues found will be reported on a daily basis via desktop notifications.
