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 benchmark built from third-party code (OWASP NodeGoat, Juice Shop, DVNA, and a lodash prototype-pollution example, with the hint comments stripped so no scanner can pattern-match the answer), XploitScan caught 8 of 16 vulnerabilities when each case was first added. We then fixed the rules behind every miss, and it now catches 16 of 16, so that is no longer a blind score. Bearer CLI1.50.0 catches 9 and Semgrep 1.86.0 catches 8. We don't run SonarQube on that 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 third-party code.
On our own labeled corpus of 615 fixtures, XploitScan scores 97.0% recall. The corpus, the runners, and the scoring code are public. Checked daily and rerun when rules or fixtures change (at least weekly); updates go live with the next deploy. Live figures are 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 Build)
- → 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@latest scan . - → Flat pricing (Pro $19/mo; Team $99/mo self-serve) fits the budget, and you want every finding to come with plain-English fix guidance
Side-by-side
| Dimension | SonarQube | XploitScan |
|---|---|---|
| Setup | Self-hosted server with a scanner in CI, or SonarQube Cloud (automatic analysis for GitHub, gitlab.com, and Azure DevOps repos, no CI setup) | npx xploitscan@latest scan . — no signup, runs locally; code is sent off-machine only if ANTHROPIC_API_KEY is set or you sign in |
| Scope | Broad: code quality, code smells, duplication, coverage, plus security | Focused: SAST-style security findings, tuned for AI-generated code |
| Pricing model | Free Community Build (self-host) and SonarQube Cloud free tier (up to 50k LoC); paid Server editions and Cloud plans priced by lines of code (as of October 2026) | Flat: Free $0 / Pro $19/mo / Team $99/mo |
| AI-code tuning | General-purpose rules plus AI Code Assurance (a stricter quality gate for AI-generated code) | 223 rules (30 free) targeting patterns AI tools ship by default |
| Plain-English fixes | Rule description + remediation guidance; AI CodeFix suggestions on supported editions | Plain-English explanation + suggested fix on every finding, often a code change you can paste |
| Public benchmark | Publishes TPR/FDR on OWASP Benchmark and others, with ground truth (SonarSource/sonar-benchmarks-scores) | Live, reproducible — 97.0% recall on 615 fixtures, plus a third-party set (16/16 after rule fixes; 8/16 when each case was first added) |
| CI integration | Native, via SonarScanner in your pipeline | GitHub Action (SARIF output), GitHub App (auto PR Check Runs), VS Code extension, 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's CLI runs locally (your code leaves the machine only if ANTHROPIC_API_KEY is set or you sign in to sync results), and web scans never store your code (excerpts around findings go to Anthropic for false-positive filtering; signed-in users can switch this off), but it is not a self-hosted platform you operate.
Try XploitScan on your code
Free: the CLI needs no account, and a free account adds 5 web scans a day. One command, your stack, plain-English fix guidance, often a code change 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.
