Crawlbase publishes technical guide on scaling headless browser fleets to 10,000 concurrent sessions
Crawlbase's blog post details the architecture and capacity planning required to run 10,000 concurrent Playwright sessions across roughly 100 nodes.
Briefing
- Crawlbase: Crawlbase's blog post details the architecture and capacity planning required to run 10,000 concurrent Playwright sessions across roughly 100 nodes.
Why it matters
This post provides a concrete reference point for teams evaluating whether to build or buy headless browser infrastructure. The arithmetic around 172.8 million pages per day and 100 nodes gives operators a baseline for cost and complexity, while the mention of Playwright signals the dominant tooling choice for large-scale extraction.
