## 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.

## Watch next
Will more teams adopt managed browser fleet services as the operational overhead of running 100+ nodes becomes clearer?
