The Browser Arena. Comparing how cloud browser providers perform.
Browser Arena benchmarks cloud browser providers
The Browser Arena is an open benchmark that measures how fast and reliably cloud browser providers spin up, use, and tear down remote Chrome sessions. Live results appear on browserarena.ai.
How the test runs
Each provider goes through the same routine: create a browser session through its API, connect Playwright over the Chrome DevTools Protocol, navigate to a page, and release the session. All tests run from the same EC2 instances in AWS us-east-1 and us-west-1 on t3.micro machines, so network conditions stay comparable across providers.
What it measures
The project ranks providers on reliability, latency, and cost using median values across successful runs. It offers a sequential mode of 100 measured sessions one at a time and a concurrent mode of 100 sessions in batches of 10. Before measuring, it runs 10 warm up sessions to soften cold start effects, and it uses a fixed URL of example.com for every provider.
Providers covered
The README lists Notte, Browserbase, Steel, Kernel, Hyperbrowser, Anchor Browser, and Browser Use as tested providers across AWS regions. The work extends the earlier steel-dev/browserbench, which first tested five providers, by adding more providers, a scoring system, a public leaderboard, and a structure meant to grow with new benchmarks.
Editorial conclusion
The project is written in TypeScript, licensed under MIT, and grew out of the earlier steel-dev/browserbench benchmark that first tested five providers.
