Best Browser Automation and Web Scraping APIs for AI Agents, Independently Tested on 12 Coding Agents (2026)
Lightsage ·
Direct answer
Pick Steel to drive a cloud browser, Browserbase on Claude Code and Browser Use for pay-as-you-go browsers. For scraping to JSON, pick fastCRW. All nine are agent-ready: each scored B or above when 12 coding agents did the same real task in Devtool Arena's October 2026 tests.
Here, "agent-ready" means a company score of 75 (B) or higher on Devtool Arena (devtoolarena.com), Lightsage's public leaderboard of how well coding agents use real developer tools. Every tool got the same task, agents and grader (methodology).
