Testing is the tax on your velocity.

Your team ships 3x faster. QA didn't keep up.

Cursor, Copilot, and Claude Code made development 3x faster. QA is still where it was two years ago. Every sprint, the gap grows. Testing becomes the reason you can't release on Friday.

Your test scripts break faster than you can fix them.

You tried. You wrote tests. They broke when design changed a button. Your engineers spent a week fixing selectors instead of building features. That's not a testing strategy. That's a tax.

Hiring a QA engineer costs $150K. And takes 3 months.

By the time you find someone, onboard them, and get coverage, you've shipped 30 releases untested. Most teams just ship and hope. You know how that ends.

An engineer builds the tests. AI keeps them working. Nothing slips through.

Full end-to-end test coverage without writing a single script. Every failure reviewed by a real person.

AI test generation.

Give us access to your staging environment. That's it. Your FDE analyzes your app, plans coverage, and generates Passmark-based test scripts. Real Playwright and TypeScript. You do nothing.

Self-healing execution.

Tests adapt when your UI changes. 0% flake rate. Every run produces video, logs, and AI analysis. Runs in the cloud, on every PR.

Human-verified results.

A dedicated QA engineer reviews failures, files bugs with repro steps, and gates your releases. AI speed with human judgment.

What engineering leaders say.

Prospyr
“Bug0 is the AI QA platform behind Prospyr, the practice management software for aesthetics clinics. It tests our web app continuously and points us to exactly where the app broke when something fails. We catch issues early instead of in production, which keeps a HIPAA-compliant product stable.”
Portrait of Greg Kopyltsov
Greg KopyltsovCo-founder and CTO, Prospyr
“Bug0 is the closest thing to plug-and-play QA testing at scale. It's helped us catch multiple bugs before they made it to prod.”
Portrait of Steven Tey
Steven TeyFounder, Dub
Genzeon
“We build healthcare compliance software, so accuracy and reliability are non-negotiable. Bug0 provided us with an AI-based QA layer without adding headcount or another tool for my team to learn and manage. The tests run against all of our QA instances on a regular basis, providing us with a level of coverage and confidence that previously required many resources. We can focus our team on new development and real issues, and that's the part I care most about.”
Portrait of Derek Walker
Derek WalkerCompliance Products and Solutions Manager, Genzeon
“We plugged Bug0 into our CI and had our critical flows covered within a week. Like having a proactive QA engineer reviewing every deploy.”

Ferra
“Bug0 is the AI QA platform behind Ferra, AI estimating software for steel construction. AI-based testing and execution with a forward deployed engineer who verifies every result, so we catch real bugs before production instead of chasing false positives. We see exactly where things broke, and we ship with confidence.”

“Bug0 gives us the speed of AI-native automation with the accuracy of human QA. We stopped worrying about flaky tests entirely.”

“We'd been putting off test coverage for months. Bug0 had our critical flows covered in under a week. No scripts, no maintenance burden.”
Portrait of Tomer Barnea
Tomer BarneaCo-Founder, Novu
“We used to skip regression tests before releases because they took too long to maintain. Bug0 runs them on every PR now. We haven't shipped a regression in three months.”

How your FDE gets you to full coverage.

Day 1

Your FDE analyzes your app.

You share access to your staging environment. That's all we need. Your FDE explores the app, maps your critical flows (signups, checkouts, dashboards) and drafts the coverage plan. No briefs, no walkthroughs, no work on your side.

Slack — #bug0-qa
Day 3

Your FDE has tests running in CI.

Your forward-deployed engineer generates Passmark-based test scripts, real Playwright and TypeScript, for every critical flow in the plan. Tests plug into your CI pipeline and self-heal when your UI changes.

github.com/acme/app/pull/847
Week 2

Full coverage. Your FDE handles the rest.

Every critical flow is tested on every deploy. Your forward-deployed engineer reviews failures and files bugs with video, logs, and repro steps. You ship. Nothing breaks.

Slack — #bug0-qa

Included in every plan

  • Self-healing tests. Tests adapt when your UI changes. No broken selectors.

  • Video + AI analysis. Every failure includes video replay, logs, and root cause.

  • CI/CD in minutes. GitHub Actions, GitLab, or any CI. Set up in week one.

  • Open-source engine. No vendor lock-in. Runs on Passmark, our OSS framework.

  • Dedicated Slack channel. Direct line to your FDE. Not a ticket queue.

  • Bug reports with repro. FDE files issues with video, logs, and steps to reproduce.

  • Release gating. FDE blocks deploys when critical tests fail.

  • Weekly coverage reports. What's tested, what's new, what broke. Every week.

  • Test maintenance included. App changes? Your FDE updates the tests, not your engineers.

Frequently Asked Questions

An AI testing platform that writes, runs, and heals your end-to-end tests. Plus a forward-deployed engineer who verifies every failure, files bugs with video and repro steps, and gates your releases. $2,500/mo flat. Everything included. The test engine itself, Passmark, is open source at github.com/bug0inc/passmark.
Most teams have 100% of critical user flows covered in 7 days. Larger apps take 1–2 weeks. Full app coverage in 4 weeks. Results start in your first week.
$2,500/mo flat for a dedicated QA engineer plus the full AI platform. That saves $150K+/yr compared to hiring an in-house QA engineer ($130–150K salary + benefits + tooling + infra). Month-to-month, no annual contracts.
They join your Slack (or Teams, or email), work in your timezone, and plug into your sprint. They can attend standups and planning sessions. Their job: deliver coverage, monitor tests, catch regressions before production, and report back weekly. Think of them as a senior QA engineer on your team, without the $150K/yr hiring cost.
Tests auto-heal. 0% flake rate. Passmark, our open-source engine, executes each step from intent. When your UI changes, the AI re-resolves the step instead of failing on a brittle selector or XPath. Your dedicated QA engineer monitors every run. You never deal with broken locators.
Your dedicated QA engineer investigates the failure, confirms whether it's a real bug, and files a report with video recording, network logs, console logs, and repro steps. Reports go to GitHub, Slack, or wherever you need them. You get actionable bugs, not noise.
A contractor costs $80–150/hr and still needs your tools, infra, and management overhead. Bug0 gives you the engineer AND the platform for $2,500/mo flat. The engineer builds the tests on Bug0's AI engine, verifies results, and files bugs; the engine runs and maintains the suite. No tooling to buy, no infra to manage, no contractor to manage.
Yes. Bug0 handles authenticated flows, SSO, 2FA, and session management. You provide credentials through a secure secrets vault. Your QA engineer configures auth as part of onboarding. Most teams have auth flows tested within the first few days.
