Run browser agents for job applications, logins, and data fetching

A poster tested six browser agents on daily tasks like job applications, logins, data fetching and posting; Manus was versatile but tripped bot detection and cost too much.

What They Did

The poster compared six browser agents on everyday multi-step tasks including job applications, logging into sites to fetch data, posting on their behalf, solving assignments, and API/troubleshooting discovery. They tested ChatGPT agent, Manus, Perplexity Computer, Perplexity Comet, and two local Playwright-based setups; the key difference they called out was Comet running inside their own browser, while the local stacks failed even on simple tasks.

How It Went

Comet was their best balance, while Manus was capable but too expensive for daily use and still hit bot detection; ChatGPT agent was the worst performer, and the two local model setups were not production-ready. In comments, they said most of their cases were multi-step tasks inside authenticated sessions.

Worth Knowing

Their main catch was economics and auth friction: tools that start fresh browser sessions kept running into logins and bot detection, and the strongest cloud options were too costly for daily use.
