The best AI browser agents, tested and ranked

HARPA AI came first of seven with 3 out of 5, scoring an even 3 on every part. It got 146 of 200 runs right first time, the best result in the test, and retries rescued 39 of the 54 that failed. Seven of 10 connections worked without code, and each workflow took about 110 minutes to build. Our full HARPA AI review has the details.

HARPA is an extension for Chrome, Brave, Opera and Edge that adds an AI side panel to the page you're on. It summarises, drafts, watches pages for price drops and runs commands that click, fill forms and pull out data. You can use its cloud tokens, your own API key or your ChatGPT, Claude or Gemini session.

The catches: paid plans are only sold billed yearly, there are no refunds, it doesn't work in Firefox and we found no certifications beyond a GDPR claim. Users rate it 4.7 out of 5 on the Chrome Web Store from 3,149 reviews (checked November 2026).

Skyvern came second with 3 out of 5, held back only by flexibility at 2.5. It got 139 of 200 runs right first time, retries rescued 40 of 61 failures, and 7 of 10 connections worked without code. Building took about 110 minutes per workflow, and it raised an alert in 6 of 10 failure cases. Our Skyvern review covers the full test.

Skyvern uses language models and computer vision to work websites it hasn't seen before. You can build a workflow by chatting, uploading a written procedure, showing it what to do, using the visual builder or writing code. The cloud solves CAPTCHAs, uses proxies and handles two-step logins on Pro, and the core is open source under AGPL-3.0.

There's no permanent free cloud plan, fees are non-refundable, and the terms allow training on anonymised data unless you have an enterprise agreement. It lists SOC 2 Type II and HIPAA. Its only Trustpilot review gives 3.2 out of 5 (checked November 2026).

Browser Use came third with 3 out of 5. Its first-time results were middling, 129 of 200 runs right, which gave it 2.5 for reliability, but retries rescued 47 of 71 failures and it was the quickest to build, at about 107 minutes per workflow. Six of 10 connections worked without code. Read our Browser Use review.

Browser Use began as a free, MIT-licensed Python library that lets an AI model drive a browser, and has about 120,000 stars on GitHub. It now also sells hosted agents and cloud browsers built to get past bot checks. It works with any model through your own API key, and with coding tools such as Claude Code and Cursor.

There's no visual builder, so it's not for non-coders, and with no subscription your costs follow your usage. We found no published refund policy and no customer reviews on review sites yet.

Axiom came fourth with 2.5 out of 5. It got 119 of 200 runs right first time, and retries rescued 51 of 81 failures. Only 5 of 10 connections worked without code, which gave it 2 for integrations, and each workflow took about 131 minutes to build. Value for money was its best part at 3. Our Axiom review explains more.

Axiom is a Chrome extension for building bots that click, type, scrape and copy data between sites. You add steps one by one or describe the bot and let AI put it together. Bots run in Axiom's cloud, on a schedule from Pro, or on your own computer with no time limit. It connects to Google Sheets, Zapier, Make and n8n.

Its bots follow set steps rather than planning their own, so it suits repeatable tasks you can supervise. We found no refund terms, and its single Trustpilot review, 3.2 out of 5 (checked November 2026), alleges an account takeover, an unverified claim.

Steel came fifth with 2.5 out of 5, though it was more reliable than its rank suggests: 136 of 200 runs came out right first time, the third-best result, and retries rescued 40 of 64 failures. Setup pulled it down, scoring 2. Each workflow took about 137 minutes and 4 of our 10 connections needed code. Our Steel review has the full results.

Steel runs isolated browsers that your own agent drives through Playwright, Puppeteer or Selenium. Steel Browser is open source under Apache 2.0 and you can host it yourself with Docker, while Steel Cloud is the managed version. Every plan includes recordings, traces and a live viewer.

Read the terms before you scale. They prohibit scraping without permission and automated use, which may clash with browser automation, and accounts can be closed without notice. There's no refund policy and no user reviews to go on.

Browserbase came sixth with 2 out of 5, scoring 2 on every part. Only 114 of 200 runs were right first time, retries fixed 47 of 86 failures, and it alerted us in 6 of 10 failure cases. Six of 10 connections worked without code, and each workflow took about 127 minutes to build. Our Browserbase review goes deeper.

Browserbase is infrastructure rather than an agent. It runs browsers in the cloud so your own agent can work at scale without servers to manage, and adds search and fetch APIs, help with anti-bot walls and session replay. It backs Stagehand, an open-source framework, and raised a 40 million USD Series B in June 2025.

It lists SOC 2 Type II, but fees are non-refundable, plans renew automatically at then-current rates, and CAPTCHA solving and stealth aren't on the free plan. It has 3.6 out of 5 on Trustpilot from 2 reviews (checked November 2026).

Hyperbrowser came last of seven with 2 out of 5. It got 108 of 200 runs right first time, the lowest in the test, and retries fixed 54 of 92 failures. It alerted us in only 5 of 10 failure cases, 5 of 10 connections worked without code, and at about 139 minutes it was the slowest to build. More in our Hyperbrowser review.

Hyperbrowser runs Chrome sessions in the cloud that agents control through an API. One credit balance covers browsers, proxies, a fetch, crawl and search API, and managed agents, including its own open-source HyperAgent. CAPTCHA solving and residential proxies start on the Startup plan.

It says its security programme is aligned with SOC 2 criteria but names no report, and we found no refund terms or user reviews.
