What is technical debt?+
Technical debt is the implied cost of rework caused by choosing an easy solution now instead of a better approach that would take longer. LegacyCode MRI measures and quantifies technical debt in your codebase automatically.
How does LegacyCode MRI differ from SonarQube?+
SonarQube gives you raw code quality metrics. LegacyCode MRI translates those metrics into business risk — which modules will cause your next outage, how much refactoring will cost, and who on your team is a single point of failure.
Does LegacyCode MRI store my source code?+
No. We use read-only GitHub access and never store your source code. Only metadata and risk metrics are retained.
What programming languages does LegacyCode MRI support?+
JavaScript, TypeScript, Python, Go, Java, Ruby, Rust, C/C++, PHP, and more.
How long does a scan take?+
Most repositories complete in 3–5 minutes. Large monorepos with 1M+ lines of code complete within 15 minutes.
What is bus factor in software development?+
Bus factor is the number of team members who need to be hit by a bus before a project becomes impossible to maintain. A bus factor of 1 means only one person understands a critical part of the codebase. LegacyCode MRI detects these single points of failure automatically.
Is LegacyCode MRI free?+
Yes. LegacyCode MRI has a free tier that includes 3 repositories and 1 scan per month. No credit card required.
What is the best alternative to SonarQube?+
LegacyCode MRI is a modern alternative to SonarQube that adds AI-powered risk prioritization, business impact scoring, and executive-ready reports. Setup takes 2 minutes vs 2 hours for SonarQube.
