🧠 Vibe Testing AI Agent

Inspiration

AI lets teams ship in ˜˜hours˜~minutes what used to take weeks. But that same speed breaks things faster than humans can test.

I wanted to build something that could feel the pulse of an app instantly. A way to test the “vibe” of quality, not just the code.

What it does

Drop a URL.

The agent analyzes your web app (the URL screenshot), identifies the top 3 most critical user flows, runs them instantly, and generates a clear, human-friendly report written by Anthropic’s LLM.

Testing that matches AI speed! Not slows it down.

How we built it

• Playwright for quick screenshot
• Browser-use for live execution
• Anthropic LLM for describing, prioritizing, and reporting
• Daytona sandbox to run tests safely (feature idea, not implemented)
• Galileo.ai to self-critique and refine test prompts (feature idea, not implemented - MVP implemented only with Antropic call)
• Lovable.dev and Cursor - for quick iterations

All wrapped into one tight feedback loop: URL → tests → report.

Challenges we ran into

• Simplicity was the hardest part.
• Every new idea tried to grow into a full platform. I had to keep cutting until it felt effortless.
• Another challenge: getting the AI to pick meaningful tests, not random ones — teaching it to think like a QA engineer, not a code generator.

Accomplishments that we’re proud of

• We made testing feel light.
• You can go from zero to your first meaningful test run in under a minute.
• Watching the agent analyze, execute, and explain without scripts or setup feels like the future of QA.

What we learned

When speed ↑ and coverage ↑ together, confidence follows.

Formally: $$ \text{Testing Confidence} = f(\text{Speed}, \text{Coverage}) $$ Our goal is to make $$ f \text{ grow with AI speed, not against it.} $$

What’s next for Vibe Testing Agent

We’ll add:

• Export to Playwright or Cypress code & run in Daytona
• Deeper Daytona integration for CI/CD
• Adaptive testing using Galileo-powered feedback loops

The mission stays the same: Make testing as instant and creative as building. 🚀
