Case Study: Visma improves code quality and speeds up reviews with CodeRabbit

How Visma enhanced code quality and streamlined reviews

Visma, a major European ERP provider, faced significant challenges maintaining its large, mission-critical legacy codebase, which contained over 3 million lines of code and intricate cross-dependencies. This complexity made it difficult for developers to navigate changes safely and for new team members to onboard without introducing errors. To address this, Visma adopted CodeRabbit's AI-powered code review tool to enhance their quality assurance process.

By implementing CodeRabbit, Visma's developers received AI-generated summaries, sequence diagrams, and critical feedback that caught bugs and edge cases human reviewers often missed. This solution from CodeRabbit accelerated the code review cycle, reduced the number of incidents reaching production, and freed up human reviewers to focus on complex business logic. The success led to a marked increase in code quality and prompted other internal teams at Visma to adopt CodeRabbit as well.
