What SonarQube does well
- • Tech debt focus — historical quality measurement, code smells, duplications.
- • 30+ languages in Sonar's flagship server edition.
- • Pull request decoration in GitHub/GitLab/Bitbucket.
- • Quality gates for blocking deploys based on metrics.
- • Large, active OSS community (SonarQube Community Edition is free) and an engineering blog covering rule design and analyzer internals.
Where the choice differs
| StaticCodeAudit | SonarQube self-hosted | SonarCloud | |
|---|---|---|---|
| Deployment | Single binary, no server | Server + DB to deploy & maintain | SaaS |
| Source code uploaded? | No | No (on-prem) | Yes |
| Primary focus | Security + compliance | Tech debt + quality | Tech debt + quality |
| Compliance matrices | CWE, WCAG, ISO 27001, ASVS, NIST CSF — built-in | Limited | Limited |
| Pricing | €990 → €30 K+/year (flat) | CE free; Developer/Enterprise per LOC | Per LOC + per private project |
| Maintenance burden | None (single CLI) | DBA + ops engineer | None (SaaS) |
| Self-contained HTML report | Yes — single .html file | No (web UI) | No (web UI) |

They're not always substitutes
SonarQube's strength is tech debt and quality metrics over time — code smells, duplications, cognitive complexity. StaticCodeAudit's strength is security findings and compliance reporting — CWE traceability, ISO/ASVS matrices, GDPR/RGPD detection, OWASP CI/CD.
Many teams run both: SonarQube for the dev team's quality gates, StaticCodeAudit for the audit binder. They are not a 1:1 swap.
Pick StaticCodeAudit if…
- ✅ You don't want to operate a SonarQube server (DB, JVM, upgrades, scaling).
- ✅ Your priority is security & compliance reporting, not tech debt.
- ✅ You need a self-contained HTML report for an audit, an investor, a regulator.
- ✅ You want predictable flat-fee pricing regardless of LOC growth.
Architecture in one sentence each
StaticCodeAudit
A single binary you launch from a terminal. No server to deploy, no database to back up, no JVM to upgrade. Drop it in a directory, run it, get an HTML report. Suitable for an air-gapped laptop or a CI runner with the binary cached.
SonarQube
A server you self-host: Java application + PostgreSQL (or MySQL/SQL Server) database. Code analysers (sonar-scanner) push results to the server. A web UI displays projects, Quality Gates, history. Operations include backups, JVM tuning, upgrade migrations across major versions, and DB scaling for large orgs. SonarCloud is the SaaS variant (managed by SonarSource).
SonarQube's deeper feature set (Quality Gates, baseline diff, pull-request decoration, project dashboards) comes from being a long-running server with a database. StaticCodeAudit deliberately ships zero server — the trade-off is fewer team-level features in exchange for zero infrastructure burden.
Concrete pricing scenarios (annual)
SonarQube Community Edition is free but self-hosted (you pay for the server, the DB, the ops). Developer/Enterprise/Data Center editions are commercial, priced per lines of analysed code (sliced into tiers). SonarCloud is per-developer SaaS. StaticCodeAudit is a flat annual fee per capacity tier — no infra cost, no LOC counting per se.
| Scenario | StaticCodeAudit | SonarQube |
|---|---|---|
| Solo / freelance 1 developer, ~50 K SLOC |
990 €/year, zero infra | SonarQube CE free + a self-hosted server (small VPS ~€5-10/mo) or SonarCloud free for public repos |
| Startup / small team 10 developers, ~500 K SLOC |
3 990 €/year, zero infra | SonarQube Developer Ed. starts around 150 €/year/100 K LOC tier (≈ 1 500 €/year for 1 M LOC) + server + ops |
| Mid-market / regulated 30 developers, ~2 M SLOC |
11 990 €/year, zero infra | SonarQube Enterprise Ed. starts around 20 000 €/year for 2 M LOC band + production-grade server + DBA budget |
SonarQube editions and tiered pricing source: sonarsource.com/plans-and-pricing. Server/infra costs are additional and depend on your hosting choice. StaticCodeAudit needs no server.
Frequently asked questions
Can I run SonarQube without a database server?
No. Every SonarQube edition (Community to Data Center) requires a relational database (PostgreSQL recommended). The default H2 database is documented as evaluation-only, not production. So « self-hosted SonarQube » always includes server + DB to operate. StaticCodeAudit, by contrast, runs as a CLI with file I/O only — no DB anywhere.
Does StaticCodeAudit cover the same set of issues as SonarQube?
Partial overlap. SonarQube covers code quality (code smells, duplications, maintainability) and security. StaticCodeAudit is security-focused (8 categories: security, code quality, architecture, maintenance, dependencies, CI/CD, database, accessibility) with explicit compliance metadata. If your top need is « clean code metrics + tech-debt tracking », SonarQube has more there. If your top need is « security findings ready for audit », StaticCodeAudit is more direct.
What about Quality Gates and PR decoration?
SonarQube's Quality Gates (configurable thresholds blocking PRs) and pull-request decoration are server-side features valued by mid/large engineering orgs. StaticCodeAudit ships threshold checks in audit.config.json (thresholds.max_high, thresholds.min_health) which a CI job can read to fail a build — no server needed — but the visual integration into PR pages is not native.
How does each handle multi-language repos?
Both scan multiple languages in one invocation. SonarQube covers 30+ languages, StaticCodeAudit covers 8 (Python, JavaScript/TypeScript, HTML, Java, C#, PHP, YAML, Dockerfile). If you have Go, Rust, Ruby, Kotlin or Swift, SonarQube has the coverage today.
Can StaticCodeAudit replace SonarQube?
Depends on what you use SonarQube for. If you use it mainly for « security findings + audit evidence », StaticCodeAudit can replace it with much lower ops cost. If you use it for « engineering dashboards, project metrics, tech-debt management across years », SonarQube remains the broader platform. Many teams run StaticCodeAudit pre-commit / per-release for security + audit and keep SonarQube for engineering metrics.
