Bladebro is an agentic browser driver built from the agent's perspective. Instead of 20+ tools that each do one thing, Bladebro gives you 5 tools that together provide full control. It drives stock Chromium over CDP, holds a persistent Live Page Model across tool calls, and returns diff-first results: the agent sees what changed, not the whole world, every single time.

🏆 Stealth Bench V1: 85% (68 / 80)

Bladebro was run against browser-use's Stealth Bench V1: 80 real, anti-bot-protected production sites across 11 vendors. It walked through 68 of 80 (85%), above every provider on browser-use's published leaderboard (browser-use-cloud 81%).

• Out of the box: one IP, no proxy, no captcha solver, no fingerprint rotation, no cloud. Stock Chromium with Bladebro's stealth layer on by default.
• Honest run: real navigation of the real 80 sites; an opencode agent (open model) acted as the browsing agent because we had no paid access to browser-use's cloud agent, and the deviations are disclosed in full. The benchmark isolates browser stealth from agent ability, and the defensive layer being measured is Bladebro's own.
• Per-vendor: perfect on Cloudflare (22/22) and reCaptcha (6/6); cleared the two sites browser-use-cloud's own results did not (Shape, Temu). Single named gap: Akamai (3/6).
