AI exploratory testing that explores, heals, and gates every PR
Autonomous agents map your product, self-heal tests when the UI shifts, and gate pull requests before regressions merge. One engine from first commit to compliance audit.
Six testing disciplines. One AI agent.
Most tools stop at web tests. BugBrain explores and tests your web and mobile apps, APIs, load, security, and accessibility & compliance, all from the same autonomous agent.
AI app testing
Only usPut chatbots and LLM features through their paces for hallucinations, prompt injection, and broken tool calls.
Web app testing
BugBrain explores your web app like a real user, then turns the flows it finds into self-healing tests.
Mobile app testing
NewRun native iOS and Android flows on real cloud devices, driven by the same AI agent.
API & load testing
Check API collections, catch OpenAPI drift, and push real traffic at your endpoints to find the breaking point.
Penetration testing
NewAuthorized web and API security scans that prove real vulnerabilities with evidence you can act on.
Compliance & accessibility
WCAG and ADA scans plus SOC 2, GDPR, and EU AI Act evidence your auditors can actually use.
An AI engineer for every stage of testing
The capabilities that let teams ship faster without breaking production.
Catch regressions before they ever merge
Install the GitHub app and BugBrain reviews every pull request. It reads the diff, tests the flows your change actually touches, and posts a pass/fail check with the findings right in the PR.
- Diff-aware test impact analysis
- Advisory or required GitHub checks
- Tests the PR's own preview deployment
- Never fails a PR over pre-existing bugs
Test chatbots and LLM features, not just buttons
BugBrain probes your AI copilots for hallucinations, prompt injection, and broken multi-turn context, the kind of failure traditional E2E tools never look for.
- Prompt-injection and jailbreak probes
- Hallucination and factual-accuracy scoring
- Multi-turn conversation validation
- Score-based gates, not brittle exact-match asserts
It tests your app like a real user
Give BugBrain a URL and it starts clicking around like a curious user, signing in, filling out forms, following wherever a flow leads. Along the way it maps your whole product and turns up bugs no one ever wrote a test for.
- Zero selectors or scripts to write
- Logs in and dismisses pop-ups automatically
- Maps every screen into an Application Knowledge Graph
- Prioritizes high-risk, unexplored areas first
Run QA without leaving your editor
The BugBrain MCP server puts testing right inside Claude Code, Cursor, and Codex. Kick off a run, pull up issues, or generate test cases from the same chat that wrote the code.
- Install with npx -y @bugbrain/mcp
- Run tests and read findings without switching tools
- Scoped API keys with least privilege
- Listed on the official MCP registry
Every bug arrives ready to fix
No vague alerts to chase down. Each finding lands with a root cause, severity, reproduction steps, and screenshots from the real run.
- Root cause and a suggested fix
- Severity and impact scoring
- Screenshots and the full step-by-step trajectory
- Repro steps a developer can follow in one read
Tests that fix themselves when your UI changes
When your UI shifts, BugBrain finds each element again through four fallbacks: cache, DOM graph, accessibility tree, then vision. Tests keep passing instead of flaking.
- Four-tier locator resolution
- Auto-quarantines genuinely flaky tests
- Learns from every heal to reduce future flakes
- Recovers when the UI changes, no rewrites
Accessibility, compliance, and APIs included
BugBrain replaces the patchwork of point tools your team stitches together today.
Accessibility audits
Automated WCAG scans catch accessibility barriers before your users do.
Compliance evidence
Turn test runs into ADA, WCAG 2.2, SOC 2, and GDPR evidence your auditors can use.
API testing
Collections, OpenAPI drift detection, and response checks that run beside your UI tests.
Stakeholder reports
Executive, release-readiness, and audit reports, generated for you.
Connect once. Test forever.
Give it your URL (that's it)
No SDKs, no config files, no code changes. Paste your app URL, add login credentials, and BugBrain starts exploring in minutes.
AI explores and tests
BugBrain works through your flows like a user, runs your test plans, and checks accessibility and APIs as it goes.
Bugs arrive pre-investigated
Each finding includes root cause, severity, reproduction steps, and screenshots. Your developers open the ticket and start fixing.
Gate every release
Pre-merge PR checks and scheduled runs keep regressions out of production.
Strong controls, built in
Security isn’t a tier. It’s the foundation, and here’s what protects your data from day one.
Per-organization isolation
Every database query is scoped to your organization at the ORM layer, so tenants can never see each other’s data. Isolation is enforced by code, not convention.
Encryption at rest
Stored credentials are encrypted with AES-256-GCM and passwords are hashed with argon2id. Secrets are redacted from every log line.
Least-privilege access
Scoped API keys, fully audited admin actions, and SSRF-guarded outbound requests keep access tight and every action attributable.
Secure by default
Strict content-security policy, signed and replay-protected webhooks, and brute-force-throttled logins ship on day one.
Platform questions, answered
How is this different from writing Playwright or Cypress tests?
BugBrain writes and maintains the tests for you. It explores on its own, generates reusable cases, and self-heals selectors when the UI changes, so you are not authoring or repairing specs by hand.
Does it only test the UI?
No. Alongside end-to-end UI testing, BugBrain covers API collections with OpenAPI drift detection, automated WCAG accessibility scans, and compliance evidence generation.
How does the pre-merge PR check work?
Install the GitHub app and BugBrain analyzes each pull request’s diff, selects the impacted flows, tests the PR’s preview deployment, and posts an advisory or required check with findings.
Can engineers use it without leaving their editor?
Yes. The MCP server exposes BugBrain to Claude Code, Cursor, and Codex, so engineers can run tests, inspect issues, and generate cases right inside their AI IDE.
