DebtLens vs SonarQube
They solve different problems. The honest answer: use both.
The short version
SonarQube tells developers which lines of code have smells, bugs, and vulnerabilities. It reads your source code.
DebtLens tells leadership how much those smells cost and what to fix first. It reads your git history.
Different inputs. Different audiences. Different outputs. Use both.
| Dimension | DebtLens | SonarQube |
|---|---|---|
| What it reads | Git history (commits, authors, file changes) | Source code (syntax, AST, rules) |
| Audience | CTOs, tech leads, CFOs | Developers, code reviewers |
| Main output | Cost in euros, team-level signals | Line-level issues, quality gates |
| Sample finding | "This file costs you €450/month in bug-fix time" | "Line 42 has a code smell: cognitive complexity 18" |
| Team velocity analysis | ✅ Bug-fix ratio, velocity trend, AI governance | ❌ Not analyzed |
| Knowledge silos | ✅ Per-file author concentration | ❌ Not analyzed |
| Merge discipline | ✅ Self-merge detection | ❌ Not analyzed |
| Code smells / bugs | ❌ Not analyzed | ✅ Core feature |
| Security vulnerabilities | ❌ Not analyzed | ✅ SAST rules |
| Coverage integration | ❌ Not analyzed | ✅ Core feature |
| Setup | 5 min (single binary, local) | Server install + scanner config |
| Privacy | Code stays local | Code read by scanner, stored in server |
Using them together
In most mature teams, SonarQube fires during CI to block obvious quality regressions at the pull-request level. DebtLens runs weekly on main to surface the strategic picture: where time is leaking, which parts of the codebase to prioritize, how to explain it to finance.
SonarQube handles
- • PR-level gates (fail the build on new smells)
- • Security vulnerabilities (SAST rules)
- • Coverage tracking
- • Per-line issue list for developers
DebtLens handles
- • Cost translation (euros/month, euros one-time)
- • Hotspot prioritization (behavior-based)
- • Knowledge-silo and bus-factor visibility
- • AI governance and merge discipline
- • CFO-ready PDF narrative
Keep SonarQube running. Add DebtLens to the stack.
