Testing is the tax on your velocity.

01

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.

02

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.

03

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.

Testing is the tax on your velocity

We built Bug0 so you don't have to choose between speed and confidence.

AI writes the tests and keeps them working. A human makes sure nothing slips.

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

Bug0 human-in-the-loop QA verification
01

AI test generation

Describe a flow in plain English or upload a screen recording. Bug0 converts it to end-to-end test steps you can edit and run. Zero Playwright syntax required.

02

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.

03

Human-verified results

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

Your next deploy is covered. Human-in-the-loop from the first test to the last review.

What engineering leaders say.

We plugged Bug0 into our CI and had our critical flows covered within a week. Like having a proactive QA engineer reviewing every deploy.

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.

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.

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

We map your critical flows

Your FDE starts immediately. Share your critical flows — signups, checkouts, dashboards — or let Bug0's auto-discovery scan your app and surface them. Plain English descriptions, screen recordings, or video walkthroughs all work.

Bug0 test creation interface with natural language input
Day 3

Your FDE has tests running in CI

Your forward-deployed engineer uses Studio to generate and refine self-healing tests for every critical flow. Tests plug into your CI pipeline and adapt automatically when your UI changes.

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.

Bug0 test reports and analytics dashboard

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.

Why we built Bug0

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. For teams that prefer self-serve, Bug0 also offers Studio starting at $250/mo.
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. For self-serve Studio users, you can have tests running in CI in about 10 minutes.
$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. Bug0 also offers a self-serve Studio plan from $250/mo for teams that want to run tests themselves.
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. Bug0 uses vision-based AI that interprets your UI the way a user does, not through CSS selectors or XPaths. 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 AI generates and maintains tests. The engineer verifies results and files bugs. 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.
GitHub Actions and the Bug0 app. Tests run on every PR, every commit, or on a schedule. Integration takes about 10 minutes. Your QA engineer sets this up during onboarding.
SOC 2 certified. No codebase access required. Enterprise plans include SLAs, NDAs, and custom security reviews. BAAs available for healthcare customers.
The Bug0 platform is not open-source. The test engine it runs on, Passmark, is. Passmark is open-source and available at github.com/bug0inc/passmark. You own the engine your tests run on. If you ever leave Bug0, your tests still work.
Passmark is the open-source AI regression testing framework that powers Bug0. Both Studio and Managed run on it. Tests are Playwright-based. Passmark handles test discovery, self-healing, and caching for speed. Source code is at github.com/bug0inc/passmark.
We offer 90-day paid pilots at $2,500/mo. No long-term commitment. Cancel anytime. Studio pilots are also available month-to-month from $250/mo.
Your QA engineer joins your Slack, maps your critical user flows, and starts generating tests. Most teams have tests running in CI and first results within 7 days.
