🕹️ Use case · Browser agent to do web tasks for you

What's the best AI browser agent to do web tasks for you?

Short answer

The best free AI browser agent right now is Retriever AI (rtrvr.ai): it runs in Chrome or the cloud, and its ad-supported free tier includes the AI usage, so you don't need an API key. If you already pay for Claude, Claude in Chrome works inside the tabs you're signed in to. Developers building their own agents should look at the open-source Browser Use.

The ranking

  1. #1

    Retriever AI (rtrvr.ai)

    New · Issue #1

    Best for: Anyone who wants an AI to click through websites for them: finding leads, shortlisting creators, filling out job applications.

    Verdict: The lowest-friction way to try a real browser agent. It runs in Chrome or the cloud, and the free tier includes the AI usage, paid for by ads, so you don't need an API key or a subscription. Its "#1 on Web Bench" claim comes from the company itself, so test it on your own tasks. Check what it will do on sites you're logged into before giving it outreach work.

    Price: Free (ad-supported). Paid plans: Starter $9.99/mo, Pro $29.99/mo, Team $99.99/mo, Scale $499.99/mo. (checked 2026-10-15)

    Claude in Chrome

    Established pick

    Best for: People already paying for Claude who want an agent that works in the tabs they're signed in to.

    Verdict: It reads the page you're on, then clicks, types and fills forms, and it can run tasks in the background. It stops before purchases and other one-way actions. Anthropic itself warns about prompt injection and advises against using it for banking or sensitive data, so start with site-by-site permissions.

    Price: Included with Claude Pro: $20/mo, or $17/mo billed annually. Not on the free plan. (checked 2026-10-15)

  3. #3

    Browser Use

    Established pick

    Best for: Developers building their own browser automations or agents.

    Verdict: An open-source Python library for browser agents, plus a cloud with hosted browsers and an agent API. You choose the model and pay its token cost plus 20%. Its own benchmark shows cost per task ranging from cents to several dollars depending on the model. It's a building block for developers, not a consumer app.

    Price: Pay as you go, no subscription: browsers $0.02/hour, agents at model cost + 20%. $1 free credit for eligible sign-ups. Open-source library is free. (checked 2026-10-15)

  4. #4

    Zapier Agents

    Established pick

    Best for: Teams already on Zapier who want an agent that browses the web and acts across their apps.

    Verdict: Zapier Agents can use triggers, your knowledge sources, actions across 9,000+ apps, web browsing and web search. Each of those counts as one "activity." Free runs are capped at 10 activities, so it suits short, repeatable chores more than long web sessions.

    Price: Free: 400 activities/month. Pro from about $33.33/mo billed annually. (checked 2026-10-15)
