Bug0

Your AI QA Engineer | AI-native regression testing + a forward-deployed engineer. You ship, we catch.

Passmark hit 500 stars. The pattern we’re seeing: qa teams are done writing locators based scripts. They want to describe the flow and move on.

Building the best playwright ai library for regression testing in public. 💪

Already merged a few PRs last week and this one.

We would love to see more contributions!

we finally open-sourced the core engine of bug0 called passmark.

makes the old process of generating scripts with locators instantly redundant.

open to everyone. starts today.

hence we do AI QA with adult supervision…

[Shaz @shazcodes]

Our ceo fired the entire 12 person QA team last month and replaced them with an ai automated testing pipeline to save $1.2M

today, we lost $6M in orders because a bot hallucinated a discount code that made everything in the store 0.

The best part? he asked the lead dev to hop on a call with the fired QA lead to see if he’d consult for free to fix it.

corporate greed is a mental illness

getting ai ask engines to recommend your product is way easier than most think.

we did it for bug0 from scratch. 400% growth in 2 months.

giving away the playbook in a free 15 min session. covers what we did with docs, blog content, and structured data to show up in ai search results.

12 tonnes of KitKats stolen?

Thieves took a break...

My AI agent just reproduced the bug in my drawer.

@KITKAT this is P0.

We now cap interviews at 2 rounds max + a short paid trial @bug0inc. Best hires we've made came from that.

[Fazle Rahman @fazlerocks]

I've watched the same thing happen at dozens of SaaS teams:

They set up GitHub Actions. Add unit tests. CI goes green. They call it "automated testing."

Then a customer reports a bug that no test caught. Because no test was looking.

ai coding models are getting exponentially better each month. teams are shipping new features faster than ever.

here are 10 reasons why bug0 might not be a fit for your e2e regression testing… Read more

introducing the qa engineer you never have to onboard.

give it a URL. no test plan, no context. it just opens your app and starts browsing like a real user.

it finds your signup flow, your search, your checkout. stuff you'd normally spend a week mapping out in a spreadsheet before anyone writes a single test.

each flow becomes a draft test. you decide what to keep.

we're calling it bug0 discover.

the whole thing takes about 5 minutes. but here's the thing. you can leave it running. go to sleep. come back in the morning and it's found flows in your app you didn't even know existed. edge cases nobody on your team thought to document.

no qa tool has done this before. most tools wait for you to tell them what to test. this one figures it out on its own.

that's not a 2x improvement in qa productivity. that's 1000x. your test coverage grows while you're not even working.

here's what it looks like ↓
(video has been sped up)

[Fazle Rahman @fazlerocks]

A dev built an entire SaaS with AI. Zero hand-written code. Users signed up.

Weeks later: subs bypassed, API keys maxed, random data in the db.

He couldn't debug it. He didn't write it. Shut down permanently.

This is the pattern of 2026.
