Looking for a SonarQube alternative?
SonarQube is a mature, broad platform: code quality, code smells, coverage, and security across dozens of languages, self-hosted if you want it. That depth is the right call for a large polyglot org with a platform team to run it. It's a lot of machine if you're a solo dev or a small team shipping JS/TS/Python out of Cursor, Bolt, or Lovable and you just want to know what's exploitable before you deploy. Here's the honest comparison.
We measure detection, and we publish the numbers
On a held-out third-party benchmark (OWASP NodeGoat, Juice Shop, DVNA, lodash, and others, with the hint comments stripped so no scanner can pattern-match the answer), XploitScan caught 15 of 15 vulnerabilities. Bearer caught 9. Semgrep caught 8. We don't run SonarQube on that held-out set, so we don't claim a head-to-head number against it. What we will say is that XploitScan's detection quality is measured in public, on code the rules never trained on.
On our own labeled corpus of 230+ fixtures, XploitScan scores 100% precision (zero false positives) and about 98.7% recall. The corpus, the runners, and the scoring code are public, and the benchmark regenerates on every commit at the benchmark page. You don't have to take detection quality on faith from either of us.
When each one fits
SonarQube is great when
- → You're a larger org with a platform or security team to run and tune it
- → You need quality gates: code smells, duplication, test coverage, maintainability, not just security
- → You ship in many languages (Java, C#, C/C++, Go, PHP, plus JS/TS/Python) and want one tool across all of them
- → You want it self-hosted inside your own infrastructure (SonarQube Server / Community Edition)
- → You already have CI pipelines and a SonarQube server wired into them
XploitScan is great when
- → You're a solo dev or small team, and a platform to install and maintain is overkill
- → You're shipping AI-generated code from Cursor, Lovable, Bolt, Replit, or Claude Code and want rules tuned for what those tools ship by default
- → Your stack is JavaScript, TypeScript, or Python
- → You want to start in one command with no server to stand up:
npx xploitscan scan . - → Flat pricing ($9–$99/mo) fits the budget, and you want every finding to come with a copy-paste fix
Side-by-side
| Dimension | SonarQube | XploitScan |
|---|---|---|
| Setup | Self-hosted server (or SonarCloud account) + scanner config wired into CI | npx xploitscan scan . — no signup, runs locally, code never leaves your machine |
| Scope | Broad: code quality, code smells, duplication, coverage, plus security | Focused: SAST-style security findings, tuned for AI-generated code |
| Pricing model | Free Community Edition (self-host); paid editions and SonarCloud scale by lines of code | Flat: Free $0 / Indie $9 / Pro $19 / Team $99 per month |
| AI-code tuning | General-purpose rules for hand-written code across many languages | 210 rules (30 free, 180 Pro) targeting patterns AI tools ship by default |
| Plain-English fixes | Rule description + remediation guidance | Plain-English explanation + copy-paste fix on every finding |
| Public benchmark | None disclosed | Live, reproducible — 100% precision, ~98.7% recall on 230+ fixtures, plus a held-out third-party set (15/15) |
| CI integration | Native, via SonarScanner in your pipeline | GitHub Action (SARIF output), GitHub App (auto PR Check Runs), MCP server, any CI via the CLI |
Where SonarQube legitimately wins
- Breadth of languages. SonarQube covers dozens of languages with active rule development. XploitScan's coverage is JavaScript, TypeScript, and Python. If your codebase is Java, C#, C/C++, Go, or a polyglot mix, SonarQube covers ground XploitScan doesn't.
- Code quality, not just security. SonarQube is a code-quality platform first: code smells, duplication, complexity, test coverage, and maintainability ratings, with quality gates that block a merge on any of them. XploitScan is a security scanner. It does not measure coverage or code smells and doesn't try to.
- Self-hosted and enterprise-ready. SonarQube Server runs entirely inside your own infrastructure, with the SAML/SSO, role management, and project portfolios a large org needs. XploitScan runs the CLI locally (your code never leaves the machine) and runs web scans in memory without storing them, but it is not a self-hosted platform you operate.
Try XploitScan on your code
Free, 5 scans/day, no account required. One command, your stack, plain-English fixes you can paste straight back into the editor. SARIF output and a GitHub App for PR checks are built in.
XploitScan maps findings to SOC 2, ISO 27001, OWASP Top 10, and CWE for reference. That's informational mapping to help you organize remediation, not a certification. XploitScan is built by Cipherline LLC, Fairfield CT.
