Leapfrog

If you've hit context limits with browser MCPs sending 14K tokens per page, this is the fix. Leapfrog runs 15 parallel isolated browser sessions with 37 tools and compresses snapshots to around 1,400 tokens through smart content extraction. It ships with 19 stealth patches to dodge bot detection, automatic page classification across 18 types, and adaptive retry logic that escalates strategies when sites block or challenge requests. You get session recording and replay, network interception, cookie persistence across sessions, and optional humanization for mouse and typing behavior. Built on playwright-core, it pairs with your local Chrome or a bundled Chromium binary.
