Bug0

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)

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. hashnode.com/blog/state-of-…

@claveprep Awesome

@bug0inc This is a game changer for QA teams. Converting plain English and video recordings into self-healing test suites removes a massive friction point. The fact that it runs on every PR means continuous quality validation without manual test maintenance overhead.

E2E testing without writing a single line of test code. Type plain English. Upload a video. Record your screen. Bug0 turns it into a self-healing test suite that runs on every PR.

@RagulOnchain Yes, API is covered as part of the e2e tests. But you can also use Studio for standalone e2e API testing if needed.

@bug0inc Interesting, can it do complex flows and include API testing as well ?

bug0.com is now open to all. no sales call. no demo. Just sign up and start testing your website with our AI agents.

Every investor says the same thing: services don't scale. We're a software company. We have a self-serve platform. Teams create tests from plain English, run them in CI, get reports. Pure SaaS. But we also have FDE pods - Forward-Deployed Engineers who handle QA testing end-to-end for larger customers. They plan tests, verify results, file bugs, gate releases. Sounds like an agency, right? Here's what I've learned: the service layer isn't a compromise. It's the product lab. Every week, our FDEs see patterns. Where the AI fails. Where customers get stuck. What "done" actually looks like for a VP of Engineering who just wants to ship without worrying, catch regressions early. That feedback doesn't come from analytics dashboards. It comes from being in the workflow. We take those learnings and bake them into Studio. The service makes the software smarter. The software makes the service more leveraged. There's a debate happening right now: are agencies cooked? Can't Claude just do it? Maybe for some things. But for high-stakes work - where quality matters and mistakes cost real money - you need controlled, responsible AI-powered services. Humans in the loop. Judgment. Accountability. YC just published an RFS on this: AI-Native Agencies. Their take - AI lets you sell outcomes with software margins. Not hours. Not headcount. That's the bet we made early @ bug0. Still early, but feels good to see the thesis validated.

Testing is bespoke most of the times. Most customers we work with tell us they previously bought tools that tried to abstract away everything, leaving no room for any custom changes. That's why we just added a "script" mode to Bug0 Studio that lets engineers take control and write custom playwright to implement changes that's not supported by us. 🔗 bug0.com

agentic e2e regression testing solved. prompt → test in under 2 mins. if you're still writing tests by hand... why

agentic e2e testing. from your phone. done

genuinely wild that i can generate tests and manage full suites from my phone now. bug0 studio on mobile safari. no scripts. no army of testers. just anyone on the team, from anywhere. agentic era is here. can your legacy QA vendor do this? 😉

@Sandeepg33k 🔥 end-to-end agentic testing from mobile web!

ok this is actually insane customer just messaged us. bug0 caught a production-breaking bug 8 minutes after they deployed to staging. translation flow completely broken. would've shipped to users. caught automatically. no manual testing. no one even looking. this is why we're building this

Look at how fast @bug0inc boots up VMs. All test dependencies are pre-installed and ready to go as soon as you hit Run, thanks to @vercel sandbox snapshots. huge performance boost. h/t @rauchg

excited to see the response to bug0's private beta announcement. limited slots are available now. x.com/Sandeepg33k/st…

@Sandeepg33k Thrilled… can't wait for more teams to use me to secure their releases. 💃💚

I'm thrilled to announce Bug0 Studio - a self-serve, AI-native browser testing tool. We're in private beta. DM me your email for access + $250/mo in credits for 3 months. What you can do today: - Create tests from video recordings - Natural language test steps - Self-healing tests (adapts to UI changes) - Live browser preview - CI/CD integration (Vercel, Netlify, GitHub Actions) - Scheduled runs + reports via Slack, email, or PRs - Auto-extract emails (OTPs, magic links) - Team collaboration Most QA tools hide behind "contact us for demo." But I believe powerful QA shouldn't be gatekept behind sales calls and enterprise pricing. Help us build the most user-friendly and powerful AI QA tool that is open and accessible to all🙏 Today it's private beta. Soon, it's open to everyone.

now super charged with Gemini models @OfficialLoganK @GoogleAIStudio ❤️

this is for the teams that are vibe coding new features to their enterprise customers. with this "ai" tool, you can create a new test suite for end-to-end regression testing of your app in under 40s. … so you don't ship blindly to production. have a look.

therapist: what relaxes you? me: watching ai run e2e tests i didn't write therapist: ... me: you wouldn't get it.
