GateTest
110 QA checks in one scan, auto-fix PR for what it finds

What is GateTest?
GateTest is an AI-powered codebase scanning and auto-fix tool that runs 110 modules to scan your entire codebase for security issues, accessibility problems, performance bugs, CI rot, and more. Unlike tools that only report problems, GateTest finds bugs AND automatically opens a pull request with a tested fix, regression test, and pair-review by a second AI. The tool is built on Claude Sonnet 4 (the SWE-bench Verified winner) and uses a four-layer flywheel architecture: AST fixes, rule-based codemods, cached recipe lookup, and finally Claude for genuinely novel cases.
Key features include: auto-fix PRs delivered in ~60 seconds, pair-review on $199+ tiers, architecture reports, cross-finding attack-chain correlation on $399 tier, mutation testing, chaos/fuzz passes, SARIF output, WCAG 2.2 automated auditing (AA+AAA-aligned), OWASP security scanning, IaC security for Dockerfile/Kubernetes/Terraform, CI/CD hardening, flaky test detection, and AI code review. The GitHub App installs in one click and scans every push and PR automatically with results posted directly on pull requests.
GateTest is designed for engineering teams, developers, CTOs, and security teams who want self-healing CI. It replaces 30+ QA tools including Snyk, SonarQube, ESLint, Cypress, BrowserStack, Lighthouse, axe-core, Renovate, Dependabot, hadolint, tfsec, and actionlint. It works with Next.js, React, Vue, Express, Fastify, Nest, Prisma, Drizzle, MongoDB, Postgres, Docker, Kubernetes, Terraform, AWS, GCP, Azure, Python, Go, Rust, Java, Ruby, PHP, C#, Kotlin, and Swift.

Frequently asked questions about GateTest
Is this just another AI tool?
No. The static engine ships first with 91 deterministic modules using AST, regex, and file walkers with zero LLM calls. Claude only enters when deterministic layers can't resolve a finding, roughly 5% of fixes. The 4-layer flywheel architecture is the moat.
Is my code stored anywhere?
No. Scans are ephemeral. GateTest clones the repo, runs the engine, posts the report, then deletes the clone. The repo never leaves your CI environment when you install the GitHub Action. For paid scans from their infra, the working copy lives on a Vercel function for the scan duration and is gone when the response returns.
Why not just use ESLint + Snyk + other tools?
You can, but most teams do and then someone must maintain the compose-of-ten and pay the per-seat tax across all tools. GateTest replaces 30+ tools with one CLI, one config, and one bill.
Per-scan pricing - what's the catch?
None. You pay once via Stripe at checkout, GateTest runs the scan, and you get the report. No subscription, no auto-renew, no per-seat billing. If the scan fails to start or crashes mid-way, contact [email protected] for a re-run or credit. Scan-finish rate is above 99% on real repos.
Is the gate actually strict?
Yes. Bible Forbidden #24 bans continue-on-error: true on the gate step. GateTest dog-foods this with their own self-scan as a hard gate on every push to main. If a competitor lets you silently skip a failing check, that's how QA-platform wins slip into prod.
Can I trust an AI to repair my CI?
The fix-flow is layered for that reason: AST to rule recipe to cached pattern to Claude. Each layer's output passes a syntax gate and scanner re-validation before the PR opens. Claude never auto-merges, it opens a PR you review. At $199+ tiers a second Claude pair-reviews every fix on a 4-axis rubric covering correctness, completeness, readability, and test coverage.
What frameworks and runtimes does GateTest support?
GateTest scans every major framework, runtime, and infra primitive including Next.js, React, Vue, Express, Fastify, Nest, Prisma, Drizzle, MongoDB, Postgres, Docker, Kubernetes, Terraform, AWS, GCP, Azure, Python, Go, Rust, Java, Ruby, PHP, C#, Kotlin, and Swift.
What's included in the free preview?
The free preview includes top 3 issues plus your Health Score with no signup and no install required. You can try it on a sample WordPress site or run a self-scan.
How does the GitHub App installation work?
Install GateTest on GitHub in one click. Every push and PR gets scanned automatically with 90 modules. Results are posted right on your pull requests at github.com.
What makes Scan + Fix different from Full Scan?
Scan + Fix ($199) includes everything in Full Scan plus second-Claude pair-review critique on every fix scoring correctness, completeness, readability, and test coverage; architecture annotator showing design observations on codebase shape; both reports posted as separate PR comments; iterative fix loop with N retries where Claude learns from failed attempts; cross-file syntax and scanner gates ensuring broken fixes never ship; and regression test for every fix strengthening your suite when merged.
