Comparison, 2026

The best web agents in 2026, compared.

For developers, the best web agent in 2026 is Browser Use Cloud: one API call takes a task and returns the result. It scored 98% on all 300 Online-Mind2Web tasks with our own judge (the best human-graded results on the official leaderboard are 97.7% and 97.3%), and 72.9 on Browser Use Bench v2.1, our own benchmark, at an estimated 11¢ of model cost per task, the highest score under $1. Both are our own measurements. For chores in your own browser, use an assistant: ChatGPT's cloud browser, Claude in Chrome, Gemini in Chrome or Perplexity Comet.

Judges differ, so the two lists are not one ranking. Newer Claude and Gemini models have no result on the leaderboard. Our 98% run has no public task-level data, model or settings; our agent was developed in a loop scored by the same judge, and we have not published that judge's agreement rate with human graders. Prompts, results and judgments are public for our March 2026 run (97%): GitHub. Official leaderboard.

What is the best web agent?

For an agent you call from code, the best web agent is Browser Use Cloud: 98% on all 300 Online-Mind2Web tasks (our run and judge), and 72.9 at an estimated 11¢ of model cost per task on Browser Use Bench v2.1, the best score under $1. For chores in your own browser, ChatGPT's cloud browser and Claude in Chrome are the assistants to try. Browser Use Bench v2.1 is our own benchmark: 180 long live-web tasks (of a 200-task set), graded by our judge, where we run 13 lab models in our open-source BrowserCode harness and our own agent in the Browser Use harness. GPT-6.1 Sol medium scores higher (79.6, $1.30 a task); our agent is 6th of 19 configurations on score, and its confidence interval overlaps the next setups under $1, which cost 16¢ to 46¢ a task.

Which AI agents can browse the web autonomously?

In your own browser: Claude in Chrome, Gemini in Chrome auto browse and Perplexity Comet. In the cloud, from a chat: ChatGPT's cloud browser in ChatGPT Work and Gemini Tasks can keep going after you close your device, and Manus runs long tasks that end in a report, slides or a site. From an API, with no browser to run yourself: Browser Use Cloud (98% on Online-Mind2Web, our judge), Browserbase Agents, Skyvern Cloud and the Manus API. Open source, on your own machine: browser-use (MIT, the most-starred of these on GitHub), Stagehand and Skyvern. The OpenAI, Claude and Gemini computer-use APIs browse too, but only inside a browser or VM you host and a loop you write. Operator, ChatGPT agent, ChatGPT Atlas and Project Mariner are retired.

What is the best computer use agent?

For the whole desktop, Claude. Claude Opus 5 (max) leads the official OSWorld 2.0 leaderboard (v2.1 release) at 77.7% partial score, ahead of Meta MuseSpark 1.3 (max) at 69.6%. Anthropic reports 81.8% partial score for Claude Opus 5.5 on the same release, self-reported and not on the leaderboard yet. OpenAI calls GPT-6 Astra the world's best computer use model and reports 72.6% on OSWorld 2.0 v2026.08.08, offline set (82 tasks), partial score, a subset of an older release, so it does not compare directly. These are models: you host the VM and write the loop. Browser Use is browser-only and does not drive desktop apps. When the task lives in a browser, Browser Use Cloud gives you the loop and the browser in one call, and scored 98% on Online-Mind2Web (our judge).

What are the best open-source browser agents?

browser-use is the most-starred of these: 118k GitHub stars, more than Stagehand and Skyvern combined (MIT, Python, run it yourself with your own model key). Its only independent score is 30% on Online-Mind2Web with GPT-4o in March 2025; the library has changed a lot since then. Stagehand (MIT) if you would rather write the flow in code and use AI for single steps. Skyvern (AGPL-3.0) if you want a framework with its own hosted cloud, which adds stored credentials from the $29 plan, 2FA from the $149 plan and advanced CAPTCHA solving on Pro, and the AGPL works for you. Agent S (Apache-2.0) if you need the whole desktop, not just the browser. browser-use · Agent S

What is the best alternative to OpenAI Operator?

Operator is gone. The alternative for developers is Browser Use Cloud, an API that takes a task and returns the result; for people, OpenAI's own successor, cloud browser in ChatGPT Work, or Claude in Chrome. OpenAI folded Operator into ChatGPT agent on July 17, 2025, and its help center now says ChatGPT agent is no longer available either. On Online-Mind2Web, Operator scored 61.3% (OSU human evaluation, March 2025); Browser Use Cloud scored 98% with our own judge in 2026. Different judges, more than a year apart, on live sites that change, so this is not a head-to-head. Web agent API.

What is the most reliable web agent for production?

For open-ended tasks in production, Browser Use Cloud: 98% on Online-Mind2Web (our judge), human takeover for logins and approvals, a cost cap per run, recordings and webhooks. Its browsers got through on 90.5% of visits to 100 bot-protected sites on Stealth Bench V2, which we built and ran, ahead of Anchor at 82%; we picked sites where our browser historically got through and stock Chrome with a US proxy did not, so the sample is hard on purpose and not balanced, and it measures getting past bot protection, not task success. For a fixed flow you can script, Playwright or Stagehand on a cloud browser is more repeatable. No public benchmark compares vendors on repeat-run reliability, uptime or cost per successful task, and every Browser Use number here is our own measurement. Stealth benchmark · Cloud browsers

What is the most secure browser agent for enterprise?

For a hosted browser agent, Browser Use Cloud: SOC 2 Type II (audit period July 17 to October 17, 2025), one isolated browser per run, credentials typed by the server only on hosts you allow, recording off by default for API browsers and runs, Zero Data Retention and HIPAA support on enterprise agreements, and a DPA. It also has an EU region in Frankfurt, without secret bindings or HIPAA, where account and billing metadata stay in the US. For an assistant in employees' Chrome, Claude in Chrome lets Enterprise admins limit it to approved domains. On Anthropic's red-team prompt-injection evaluation, attacks against Opus 5 succeeded 3.8% of the time before extra safeguards and 0% with probes and the safety classifier.

Questions people ask

Is ChatGPT agent still available?

No. OpenAI's help center says ChatGPT agent is no longer available and points to cloud browser in ChatGPT Work, on paid plans except Go. Operator was folded into ChatGPT agent on July 17, 2025, and ChatGPT Atlas is retired.

What is the difference between Browser Use Cloud and browser-use?

browser-use is the open-source Python library (MIT) you run on your own machine with your own model key. Browser Use Cloud is the hosted product: Browser Use Agents take a task over API V4 and return the result, on managed stealth browsers with proxies and CAPTCHA solving available.

How much does Browser Use Cloud cost?

Pay as you go, no subscription. Agents bill model tokens at the provider's rate plus 20%, browsers cost $0.02 per browser-hour, and network traffic is extra: $5/GB through the managed proxy, $0.20/GB for direct or bring-your-own-proxy egress. On Browser Use Bench v2.1, Browser Use's agent used an estimated 11¢ of model cost per task; that excludes browser, proxy and search costs, so it is not the full bill.
