Browser Arena

Congrats Sam! The Browser Functions concept is interesting. How close to zero is the latency when your serverless code runs colocated with the browser vs a normal Lambda?

Love the focus on reproducibility. Btw do you think open benchmarks will become a norm in AI infra or will most companies still optimize for perception over truth?

Really interesting approach to benchmarking cloud browser providers. I have been evaluating a few of these services for running automated workflows and the lack of standardized benchmarks has made it difficult to compare them objectively. The fact that all results and code are public is a huge plus. Do you plan to add latency benchmarks for dynamic page interactions, or is the focus mainly on static page loads and rendering?

Wait, so u built a benchmark where your own product doesnt win 100% of the time? This level of honesty is illegal in silicone valley)

What happens when an agent session goes rogue mid-task? Curious if there are circuit breakers built into the session management layer or if the human has to manually kill it.

Hey PH! It’s Lucas, CTO of Notte 👋We built Browser Arena to make it easier for people to compare cloud browser solutions using fair, reproducible metrics.Check it out and we’d love to hear what you think!

Let's go!

Hey PH! I'm Sam from Notte. 👋We built Browser Arena because we were tired of seeing benchmarks in the AI agent/browser infra space that couldn't be reproduced. Companies claiming SOTA performance based on cherry-picked runs, undisclosed infrastructure, and small sample sizes.So we built an answer: an open-source benchmark suite that tests every major cloud browser provider under identical conditions. What makes it different❓1,000 runs per providerSame AWS infrastructure, same test, same Playwright versionFull VM metadata published (region, instance type, RTT)Median, P90, P95 — not just "best case"Error rates and failure breakdowns includedCost per session calculated from real pricingMIT licensed. Clone it and run it yourself.The benchmark ⚡Minimal session lifecycle (create → connect → navigate → release). Tests both sequential and concurrent (up to 16 parallel sessions) execution.Notte performs well in the results. But we didn't build this to win (we don't in all cases), we built it so the results mean something. If another provider is faster, the leaderboard shows it. That's the point.Run it on your own infra and tell us if your numbers differ.Would love your feedback on what benchmarks you'd want to see next! 🌸
