    Shipping Bug0 Browsers today. Real Chromium in the cloud. One API call gets you a CDP URL, and your existing Playwright code runs against it as-is. Sessions spin up in a couple seconds and shut themselves down when you're done. Built for speed. One thing, done well. If you're building agents, crawlers, or test suites, you need this. Every session ships with a live preview so you can actually watch it run. Sessions go up to 45 minutes. Sign up and you get 10 browser-minutes free to try it out.

    Replacing brittle test scripts with agentic AI. Building Bug0, AI-native prompt-to-test e2e testing platform.

    We're hiring SDETs at Bug0. We're ideally looking for candidates with 1–2 years of experience, though freshers are also welcome to apply. Strong Node.js skills are a must. Experience with Playwright is a big plus, but you should still reach out if you’re excited to learn quickly and move fast. Please DM me!

    Week 1: Playwright tests running in CI. Green. Team posts the screenshot in Slack. Month 2: Suite takes 18 minutes. Devs open a PR, context-switch, forget to check results. Some merge before tests finish. Month 3: Designer moves the "Submit" button to a sticky header. Three tests break. An engineer adds // TODO: fix after redesign. They never come back. Month 5: CI is green. But 40% of E2E tests are quietly disabled. The signup flow hasn't been tested in six weeks. A regression ships. A customer emails support. I've watched this exact timeline across dozens of SaaS teams that set up GitHub Actions for automated testing. The setup takes an afternoon. That's the easy part. The hard part is what runs inside the pipeline, and whether it's still running three months later. Most teams I talk to have "automated testing" that only covers unit tests. Their CI passes. Their checkout flow throws a 500 error. That green checkmark means the pipeline executed. It doesn't mean the product works. We wrote a guide on building a GitHub Actions pipeline that doesn't fall apart after month 3. It also covers the point where maintaining Playwright scripts yourself stops being worth the time.

    before we wrote a single line of code for bug0, we ran a free qa services company for 2 months. moved to the bay area with my wife and a toddler. airbnb for 6 months. went to founder friends and asked: let us take over your entire qa. for free. what we found was surprising. ai coding tools were great at writing code and unit tests. none of them could automate e2e browser testing at scale. hiring qa engineers cost a bomb. buying tools meant months of onboarding with nothing to show for it. so we just did the work. manually. 5 design partners in 3 weeks. nobody wanted the old school agency model with slow, manual processes. but it taught us exactly what to build. when we cracked ai agents and figured out one engineer could serve multiple customers instead of 1:1, the economics changed overnight. all 5 design partners converted to paying customers. sometimes you gotta build the agency before you build the product.

    I've talked to 200+ engineering teams this year. The ones who tried AI testing tools? Most turned them off within 2 months. The pattern: Week 1: "This is amazing, it wrote 50 tests from plain English." Week 3: "Why are 15 tests failing every run?" Week 6: Engineers spend more time triaging AI failures than they ever spent writing manual tests. Week 8: Tool gets turned off. Seed/series A stage startups. 50 to 300-person eng orgs. Same failure mode. Here's the part nobody talks about: the testing gap is getting worse, not better. Teams ship 76% more code per person than two years ago thanks to Cursor, Claude Code, and Copilot. But a CodeRabbit study on 470 PRs found AI-generated code contains 1.7x more issues. 75% more logic errors. The kind that look fine in review and break in production. More code = More bugs = No more QA. So teams reach for AI testing tools. The demos look great. Generate 50 tests from a URL. Self-healing locators. Zero config. Then 20 tests fail on a run. Half are false positives. Nobody knows which half without investigating each one manually. Your engineers are now doing triage work they didn't sign up for. Within weeks, they stop checking the alerts. The tool becomes noise. Noise gets muted. I've watched this exact sequence play out dozens of times. The tools aren't broken. The model is. The teams where AI testing actually works have a human between the AI output and the developer. Someone who confirms every failure is real before it reaches an engineer's inbox. AI generates + Humans validate That's the architecture. It's why we built Bug0 this way… the hybrid model tool + FDE. Names changed for brevity.

    we shipped something interesting today. bug0.com now serves clean markdown to ai agents instead of bloated html. ~3kb of structured content instead of ~500kb of html noise. middleware detects the Accept: text/markdown header or .md url suffix and serves the clean version automatically. when someone asks an ai assistant about testing tools, we want to be the answer it cites. not the page it skips because it couldn't parse through our react bundle. 19 landing pages, blog, knowledge base, competitor alternative pages. all agent-readable now. try it yourself: 𝚌𝚞𝚛𝚕 -𝙷 "𝙰𝚌𝚌𝚎𝚙𝚝: 𝚝𝚎𝚡𝚝/𝚖𝚊𝚛𝚔𝚍𝚘𝚠𝚗" 𝚑𝚝𝚝𝚙𝚜://𝚋𝚞𝚐𝟶.𝚌𝚘𝚖 𝚌𝚞𝚛𝚕 -𝙷 "𝙰𝚌𝚌𝚎𝚙𝚝: 𝚝𝚎𝚡𝚝/𝚖𝚊𝚛𝚔𝚍𝚘𝚠𝚗" 𝚑𝚝𝚝𝚙𝚜://𝚋𝚞𝚐𝟶.𝚌𝚘𝚖/𝚟𝚘𝚒𝚌𝚎-𝚊𝚒-𝚝𝚎𝚜𝚝𝚒𝚗𝚐 𝚌𝚞𝚛𝚕 𝚑𝚝𝚝𝚙𝚜://𝚋𝚞𝚐𝟶.𝚌𝚘𝚖/𝚕𝚕𝚖𝚜.𝚝𝚡𝚝 or just append .md to any page url. we also set up /llms.txt as a site-wide index so agents know what content exists before crawling blindly. we build ai agents that test apps e2e. making our own site agent-readable felt like the obvious next step. if you're building a website in 2026 and not thinking about agent readability, you're leaving discovery on the table.

    Just shipped a new feature to Bug0. You can now tag some of the tests on Bug0 Studio with arbitrary tags like smoke, critical, etc and run these tests selectively. Internally, we achieve this by utilizing playwright's tagging mechanism. Using pw tags via code is easy. But I believe a GUI is even better. It standardizes the usage, you can see all your tags at one place and don't need code level access.
