QA Guardian vs. Bug0
Bug0's entry price is lower — but their proprietary Passmark library ties your entire test suite to their platform. Guardian delivers standard Playwright TypeScript you own forever, across every browser.
The Risk Bug0's Price Tag Doesn't Show
Bug0 Managed at $2,500/mo looks like a bargain. But the Passmark library creates a dependency that only surfaces when you try to leave.
Bug0 — Passmark Library
Proprietary lock-in- Tests written in Bug0's proprietary Passmark library — not standard Playwright
- Cannot export or run tests outside Bug0's platform
- If Bug0 shuts down or is acquired, your entire test suite becomes unusable
- No migration path to any other service or framework
- Vision-based selectors break when visual elements change position
Guardian — Standard Playwright
Zero lock-in- Every flow written in standard Playwright TypeScript — run it with `npx playwright test`
- Full code ownership — take your tests to any vendor or maintain them yourself
- No platform dependency whatsoever
- DOM-based selectors using semantic attributes — only fail when something actually breaks
- Cancel anytime and keep every line of code forever
The real cost of Passmark lock-in: Bug0 at $2,500/mo for 24 months is $60,000. If you then switch vendors and need to rebuild every test from scratch, add the full cost of your next vendor's ramp-up time and fees. Guardian's standard Playwright code means you never pay that rebuild cost — it's yours regardless of what happens next.
Browser Coverage: Multi-Browser vs. Chromium-Only
Bug0 supports Chromium only. ~27% of web users use Safari, and enterprise compliance often requires cross-browser testing.
Bug0 Browser Support
Teams with Safari users, iOS testing requirements, or cross-browser compliance mandates cannot use Bug0 at entry pricing.
Guardian Browser Support
Playwright supports all major browsers natively. Every Guardian flow can run in Chrome, Safari, and Firefox on the same CI pass.

When Bug0 Makes Sense — and When It Doesn't
Bug0 is worth evaluating if:
- Your budget is under $3,500/mo and cost is the primary constraint
- You only need Chromium coverage and have no Safari/Firefox requirements
- You don't have compliance requirements (HIPAA, SOC 2)
- You're comfortable with month-to-month flexibility and the lock-in risk
- You want a modern AI-native testing approach and accept the Passmark tradeoff
Guardian is the stronger choice if:
- Code ownership and portability matter — you want tests you can keep forever
- You need Safari, Firefox, or cross-browser compliance coverage
- You need HIPAA BAA or SOC 2 Type II alignment
- You want pricing that decreases automatically as you scale
- You plan to eventually run or maintain tests independently of your vendor

Our honest take
Evaluating Both? The price difference narrows fast.
Bug0's $1,000/mo savings at entry disappears when you factor in the rebuild cost if you ever switch. Guardian's standard Playwright code is an asset you own — and it supports every browser your users actually use.
