Browser agents can save time, but they can also break easily. Check how reliable they are, how much they show you, and how much control you keep.
Key evaluation criteria
Check how the tool handles page changes, login flow, retries, and long-running sessions.
Look for clear logs, replayability, and a path for human intervention when the site gets weird.
Choosing the right level
If you need structured browser testing, Playwright may be enough. If you need managed sessions or more agent-like behavior, Browserbase or Stagehand may fit better.
For extraction-heavy work, pair browser automation with Firecrawl so the result is more usable.
Treat browser agents like real systems, not magic tools that always click the right thing.
