Not ideal for

OpenHack delivers real, verified vulnerabilities with PoC exploits, not noise. Its open-source model approach cuts costs dramatically, and its benchmark performance on CVE-Bench is impressive. However, it primarily targets web application logic flaws, so teams needing comprehensive SAST/DAST for infrastructure or mobile code should supplement with other tools. The free tier is generous for solo devs, but the free plan has a 3-project limit. A strong choice for budget-conscious security teams and open-source maintainers who value verified findings.
Skip OpenHack if Skip OpenHack if you need infrastructure or mobile code scanning, a plug-and-play GUI-only tool, or a dedicated DAST/IAST suite without CLI usage.

About OpenHack
FreemiumIntermediateAPI availableCLI · Web
OpenHack is an open-source AI security agent designed to hunt, validate, and verify logic-based vulnerabilities in code. It uses open-source reasoning models to understand code semantically, producing working proof-of-concept exploits for every finding, eliminating false positives. Unlike traditional pattern-matching scanners, OpenHack can find authentication bypasses, IDORs, and open redirects that others miss. It runs via CLI (install with pipx or uv) or through a hosted platform, and works with JavaScript, TypeScript, Python, Go, Java, Ruby, and frameworks like Next.js, Django, Flask, Rails, Express, and FastAPI. On CVE-Bench, OpenHack achieves a 31.25% one-day pass@1 and 27.5% zero-day pass@1 using a fully open-source model, at up to 40× lower cost than frontier-model agents. The tool is free for solo developers (3 projects, 1 user) and offers paid Pro ($50/month flat for up to 10 users) and Enterprise plans with AI Autofix, compliance reports, and SSO. OpenHack is built by Titan Security Labs and launched in June 2026.
Behind the Verdict
OpenHack stands out in the crowded security scanning space by focusing on what matters most: verified findings. Instead of drowning you in false positives, it only reports issues it can exploit — each comes with a PoC. This is a game-changer for developers who waste hours triaging noise from traditional SAST tools like Semgrep or Snyk Code. The benchmark results speak for themselves: 265 real vulnerabilities found (vs Bearer's 69, Semgrep's 36, Snyk Code's 13) and 59% accuracy (vs Bearer's 17%, Semgrep's 12%, Snyk Code's 5%). The cost advantage is real — using open-source models makes scans up to 40× cheaper than Claude Opus 4.6 or Kimi K2.5 agents. This allows you to run more scans more frequently. The CLI is dead simple: pipx install, then 'openhack scan .' No YAML or config needed. For teams, the Pro plan at $50/month flat (not per seat) is refreshingly simple, especially compared to per-user pricing from competitors. Where OpenHack falls short: it's focused on logic-based web vulnerabilities — not infrastructure scanning, mobile code, or deep dependency analysis (though it has basic SCA). The free tier limits you to 3 projects and 1 user, which may be tight for active solo devs with many repos. Also, its effectiveness relies on the open-source model you use; while evaluations show strong performance, you may get inconsistent results with weaker models. Overall, if you're a solo developer, a small security team, or an open-source maintainer wanting to catch real bugs without breaking the bank, OpenHack is an excellent addition to your toolbox. For larger enterprises needing a full DAST/IAST suite, it's a complement, not a replacement.

Real-world workflow fit
Concrete scenarios for the personas OpenHack actually fits — and what changes day-one when you adopt it.
Solo developer maintaining a side project on GitHub
Install OpenHack via pipx, run 'openhack scan .' in your project directory, review the validated findings with PoC exploits, and apply one-click fix PRs.
Outcome: You find and fix an authentication bypass and an IDOR in under 10 minutes, with zero false positives.
Small security team in a startup
Integrate OpenHack CLI into CI/CD pipeline to scan every pull request automatically. Set up Slack notifications for new verified vulnerabilities.
Outcome: Your team catches a critical open redirect before production, reducing mean-time-to-fix from days to hours.
Open-source maintainer with multiple public repos
Run OpenHack on each repo weekly via cron. Use the platform to get compliance reports for funding requirements.
Outcome: You ship two CVEs with full PoCs, earning trust from your community and maintainers.
Use Cases
- Scan your codebase for authentication bypasses and authorization flaws before release.
- Automatically verify each security finding with a working exploit to prioritize true positives.
- Integrate into CI/CD pipeline for continuous vulnerability detection on pull requests.
- Generate compliance-ready reports for audits or internal security reviews.
- Reduce security tooling costs by using open-source models instead of per-scan proprietary fees.

Limitations
- OpenHack primarily targets logic-based vulnerabilities in web applications; it may not replace comprehensive SAST/DAST for infrastructure or mobile code.
- Free tier is limited to 3 projects and 1 user.
- The tool's effectiveness depends on the underlying open-source model's capability, and while cost-effective, very large codebases may require custom inference budgets.

Integrations
Where the pricing makes sense
The company stage and team size where OpenHack's pricing actually pencils out — and where peers do it cheaper.
OpenHack's freemium model is ideal for solo devs and small teams. The Free Solo tier is genuinely free (no time limit), while the Pro Team plan at $50/month flat (up to 10 users) is much cheaper than per-seat competitors like Snyk Code ($25/user/month) or Semgrep ($40/user/month). Enterprise pricing is custom but likely cost-effective given open-source models. For larger orgs with compliance needs, the Enterprise plan adds SSO, audit logs, and on-prem deployment.
Setup time & first value
How long it actually takes to get something useful out of OpenHack — broken out by persona, not the marketing-page minute.
For solo devs: ~5 minutes (install CLI, run first scan). For team integration: ~30 minutes (install CLI, set up CI/CD integration, configure Slack/Jira webhooks). Enterprise onboarding with SSO and on-prem may take 1–2 days.
Switching to or from OpenHack
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
Migrating in
- →From Semgrep: Export your Semgrep config rules (optional), then point OpenHack at the same repos — rerun scans to get verified findings with PoCs.
- →From Snyk Code: Deactivate Snyk Code in your CI pipeline, add OpenHack step, and start getting validated exploits instead of false positives.
- →From Bearer: Bearer's SARIF output can be imported, but you'll likely re-scan with OpenHack to get verification.
Migrating out
- ↗To Semgrep: If you need broader SAST rule coverage, switch to Semgrep's community rules; note you'll lose verification and may get more false positives.
- ↗To Snyk Code: For proprietary model compliance and broader language support, migrate to Snyk Code — expect higher per-seat costs.
- ↗To GitHub CodeQL: If you prefer a native GitHub integrated SAST with community queries, use CodeQL — but it lacks exploit verification.
