What happened
Visma's R&D unit uses CodeRabbit to review pull requests on a large, 20-year-old ASP.NET ERP codebase. It flags bugs and edge cases that human reviewers miss and generates summaries and sequence diagrams that make changes easier to understand.
Summary written by usedby from the source page, in English. The figures are those of CodeRabbit and Visma, not ours.
- 600“Human reviewers carefully examined their team’s 600 monthly pull requests (a process still central to their workflow).”
- 3 million“The application's central repository contains more than 3 million lines of mostly legacy code dating back to the early 2000s.”
Since they implemented CodeRabbit, it has caught several critical bugs during Visma’s pull request stage, significantly reducing the number of incidents they have.
It's the edge scenarios that are usually difficult to catch. It's a good tool to get these edge scenarios.
