Key features
  • Python library: an Agent takes a task string and an LLM and drives a Chromium browser via CDP
  • Cloud browsers billed per browser-hour, with residential proxies and CAPTCHA solving
  • Hosted Browser Use Agents billed at model cost plus a 20% service fee
  • sensitive_data parameter keeps credentials out of the LLM prompt, optionally scoped per domain
  • Authentication via real Chrome profiles or cloud profile sync
  • Browser Harness (April 2026): raw-CDP skill for coding agents such as Claude Code and Codex
  • act(), extract() with a schema, and observe() natural-language primitives
  • Action caching so repeat runs can skip LLM inference
  • v4 runs as a browser extension next to the page to reduce latency
  • SDKs in TypeScript, Python and Go; works with local browsers by default
  • Optional hosted browsers on Browserbase (concurrency, proxies, session retention)
  • browse CLI and integrations with coding-agent and framework harnesses
Verdicts
Praised for
  • Largest community and example library among open-source browser-agent frameworks (Gonsalvez on dev.to; 116k GitHub stars)
  • Model-agnostic, including local models (Scrapfly, ByteTunnels)
  • Quick to start for Python developers (Reddit r/AI_Agents thread 1slvuta)
  • More deterministic and debuggable than fully autonomous agents because most code is standard Playwright-style (ByteTunnels; Reddit r/AI_Agents)
  • Lower token cost through caching (Gonsalvez; HN comment 2026-09-18)
Criticised for
  • Users report hallucinated clicks and brittleness on long multi-step workflows (Reddit r/AI_Agents, r/LocalLLaMA)
  • Slow and token-heavy because every action is an LLM round trip (ByteTunnels; HN comments)
  • Telemetry with task-level data is on by default (vendor telemetry doc; HN comment 2026-09-18)
  • Requires more upfront developer effort to decide which steps are deterministic (ByteTunnels)
  • Python SDK reported to lag the TypeScript SDK (Reddit r/AI_Agents)
  • Some teams found runtime AI still non-deterministic and moved to generated Playwright scripts (Reddit r/AI_Agents)
