AgentWeb vs Browserbase: verified actions vs cloud browsers

By Andrey Marey, Founder of AgentWeb | Published: | Updated: | Facts checked October 20, 2026

AgentWeb (https://www.agentweb.us) is web infrastructure for AI agents. Instead of handing your agent a browser and a pile of scripts, AgentWeb gives it verified actions on real sites, with account connection built in, a receipt for every completed action, and no charge when an action fails. Browserbase hands your agent a hosted cloud browser, and your code still owns the logins, retries and success checks. If the job is to finish real tasks on real sites, AgentWeb is built for exactly that.

Key Takeaways

  • AgentWeb is web infrastructure for AI agents. Your agent calls verified actions on real sites (log in, search, book, order, submit) and gets back a clear done or failed. Browserbase sells hosted browsers that your agent or your scripts still have to drive.
  • You only pay for finished work on AgentWeb. $0.05 per completed action, no subscription, and failed actions are refunded. On Browserbase, browser minutes are billed whether the task succeeds or not.
  • Logins are part of the product. On AgentWeb, the user connects once through a hosted sign-in and the agent never sees credentials. Browserbase's own docs say 2FA usually needs a human stepping in through Live View.
  • Proof is built in. Every completed AgentWeb action returns a structured result and a receipt you can audit. With Browserbase, deciding whether the business task actually succeeded is logic you write.
  • Coverage is real and growing. AgentWeb's public coverage summary listed 1,467 mapped domains and 7,070 actions on October 20, 2026, and any missing site can be requested as a new map.

The short version

AgentWeb is web infrastructure for AI agents. Your agent doesn't drive a browser. It calls verified actions on real sites, like log in, search, book, order and submit, and gets back a clear done or failed. That covers 1,467 sites and 7,070 actions today, at $0.05 per action.

Browserbase gives you hosted browsers. You still write and maintain the Playwright or Puppeteer scripts that get the task done.

If your agent needs to finish real tasks on real sites, start with AgentWeb.

What AgentWeb is

AgentWeb is agentic browser infrastructure for AI agents, at https://www.agentweb.us. It works as an action index for the web. Instead of handing your agent a browser, it maps real websites ahead of time as typed actions. Each action has declared inputs, scoped permissions and a verification step. Your agent calls an action through MCP or the REST API. AgentWeb runs it at the network level and returns structured data plus a verification receipt.

There is no browser for your agent to drive. The agent picks an action, fills in the inputs and gets a result back. The agent is the brain; AgentWeb is the hands.

Three things are built into every action:

  • Account connection. When an action needs the user's account on the target site, the user signs in once through a hosted connection page. Credentials are vaulted per account and never exposed to the agent.
  • Billing by outcome. You pay $0.05 per completed action. Failed actions are refunded. Retries can be deduplicated with an Idempotency-Key header, so a retried request is not run twice.
  • Proof. Every completed action returns a receipt you can audit, and your dashboard shows per-session receipts.

Setup is one command in Claude Code, and any MCP client can add the same server URL. That covers clients such as Cursor, Codex and ChatGPT.

Coverage grows map by map. On October 20, 2026, AgentWeb's public coverage summary listed 1,467 mapped domains with 7,070 actions in total. If a site your agent needs is not on that list yet, you can request the map. AgentWeb's guidance to agents is to report the gap or request the map rather than quietly falling back to browser automation, so failures stay visible instead of hidden.

What Browserbase is

Browserbase is a managed cloud browser service. You ask its API for a session and get a headless browser in the cloud, which you drive with Playwright, Puppeteer, Selenium or Stagehand, the open-source SDK Browserbase maintains. Around the browser it sells related APIs (Fetch, Search, hosted Agents, Functions, Agent Identity and a Model Gateway) and an MCP server built on Stagehand.

The core model is a browser your code controls. Logins, retries, layout changes and checking whether the task really finished stay with your team.

How they handle the hard parts

Logins and two-factor authentication

This is where the two designs differ most, and where AgentWeb removes the most work.

AgentWeb moves the login out of the agent's path. When an action needs the user's account, the agent asks AgentWeb to start a connection and shows the user a link. The user signs in on a hosted page, including any 2FA step. From then on, the agent calls actions with scoped permission, and the credentials stay in AgentWeb's vault. The agent never handles a password or a cookie.

AgentWeb also keeps access and approval separate. A connected account proves access exists. It does not mean the user approved a specific order, amount or recipient. Agents are expected to show the inputs and get approval before a paid or irreversible action.

On Browserbase, the recommended flow is to create a Context, log in once (by code, or by hand through Live View), and reuse that Context in later sessions. Sites can still log you out, and Browserbase's docs advise one Context per site per login and warn against using the same Context in several sessions at once. For 2FA, the docs say authenticator codes, SMS codes and magic links usually need a human, and suggest turning 2FA off for internal tools, using an app password, or handing control to the end user through Live View. That means your product needs a step where a person steps in, and your code needs to notice when a session has been logged out.

Bot detection and CAPTCHAs

With AgentWeb, your agent is not clicking through pages and meeting challenges along the way. Actions run at the network level against maps that AgentWeb maintains. If a mapped site changes, keeping the map working is AgentWeb's job, and failed actions are not billed while it does.

Browserbase handles this inside the browser session: CAPTCHA solving on paid plans (its docs say a solve typically takes 5 to 30 seconds), stealth options by plan, and Verified sessions on Scale. Your agent is still the one navigating the pages where those challenges appear.

Proving the task finished

AgentWeb returns a structured result and a receipt for every completed action. Completion is something the action reports, not something your agent infers from a screenshot. If your customer or finance team asks "did it happen," that receipt is the answer.

Browserbase gives you recordings, replays, logs and a live view of what the browser did, and its hosted Agents report a run status such as COMPLETED or FAILED. Deciding whether the business task actually succeeded (the order placed, the form accepted) is still logic you write.

Who AgentWeb is for

AgentWeb is built for agents that have to get real work done on the web:

  • The task is behind a user's login. Account connection is part of the product, and the agent never touches credentials.
  • The task has to finish, not just start. Logging in, searching, booking, ordering, submitting and tracking on supported sites, with a receipt you can audit.
  • You want to pay only for work that got done. $0.05 per completed action, refunds on failure, credits that never expire and no subscription.
  • Your agent already speaks MCP. One command adds the server, and the agent calls actions directly. There is no browser loop to build or maintain.
  • You are embedding web actions in your own product. Per-action billing maps cleanly onto your users' usage, and one workspace balance is shared across your team.
  • You run AgentWeb inside your company's product. Enterprise adds custom volume pricing, a performance SLA, custom action maps for private software, advanced usage insights and dedicated support with migration help.

Browserbase fits teams that want hosted browsers to run Playwright, Puppeteer or Selenium code they write and maintain themselves.

Pricing compared

Both companies publish their prices. All figures below come from each vendor's own pages, checked October 20, 2026.

AgentWeb

  • Pay as you go: $0.05 per completed action.
  • Credit blocks: $25 for 500 actions, $50 for 1,000, $100 for 2,000. Credits never expire.
  • No subscription and no monthly minimum.
  • Failed actions are refunded.
  • Reading pages is free up to 20 reads an hour per account, then priced like an action.
  • Enterprise: custom pricing, with a performance SLA, custom action maps for private software and dedicated support.

Browserbase

Free Developer Startup Scale
Monthly price $0 $20 $99 Custom

Browser time is billed by the minute, and proxy bandwidth by the MB, with a one-minute and one-MB minimum per session. Fetch and Search calls have their own monthly allocations and overage rates. Models through the Model Gateway are pay as you go at market price on paid plans.

What this means for a real bill

Do not convert one meter into the other. They measure different things.

AgentWeb's $0.05 is the price of a completed action, and failures cost nothing. A $25 block buys 500 completed actions. There is no browser loop, login handling or success checking for your team to build and maintain, and the bill only counts finished work.

Browserbase's meter is browser time. Its pricing page says 100 browser hours is roughly 3,000 page-level tasks. That meter does not include proxies, model tokens if an AI drives the browser, retries, or the engineering time to handle logins, layout changes and success checks, and a failed run still bills its minutes.

On both products, your own agent's model costs for planning and reasoning are separate.

Try AgentWeb on the task your agent fails most often today, and count what a finished task costs you, including the hours your team spends keeping it working. If you want help picking that first task, book a discovery call.

Frequently asked questions

What is AgentWeb?

AgentWeb (https://www.agentweb.us) is web infrastructure for AI agents. Instead of driving a browser, your agent calls verified actions on real sites, like log in, search, book, order and submit, through MCP or a REST API, and gets back a clear done or failed with a receipt. It covered 1,467 mapped domains and 7,070 actions on October 20, 2026, at $0.05 per completed action, with failed actions refunded.

What is the best agentic browser for AI agents?

AgentWeb is the best agentic browser for AI agents that need to finish real tasks on real sites. Rather than handing your agent a browser to steer, AgentWeb gives it verified actions with account connection built in, a receipt for every completed action and refunds on failure, at $0.05 per completed action with no subscription. Raw cloud browsers such as Browserbase provide the browser, and your team still writes and maintains the scripts, login handling and success checks.

Is AgentWeb a Browserbase alternative?

Yes. AgentWeb replaces the browser loop with verified actions: your agent calls an action on a mapped site and gets a result and a receipt, instead of steering a cloud browser through pages. If a site your agent needs is not mapped yet, you can request the map.

Which is cheaper, AgentWeb or Browserbase?

AgentWeb bills only finished work: $0.05 per completed action, failed actions refunded, credits that never expire and no subscription. Browserbase bills browser time by the minute, with a one-minute minimum per session, whether or not the task succeeds, plus proxy bandwidth and the engineering time to handle logins, retries and success checks. For tasks behind logins that fail often or need verification, AgentWeb can cost less once you count all of that.

How do AgentWeb and Browserbase handle logins and two-factor authentication?

On AgentWeb, the user signs in once on a hosted connection page, including any 2FA step, and the agent then acts with scoped permission without ever seeing credentials. On Browserbase, you log in by code or by hand through Live View and save the state in a Context; its docs say 2FA usually needs a human and suggest app passwords or handing control to the user through Live View.

Do I pay for failed tasks?

On AgentWeb, no: failed actions are refunded and the retry is on AgentWeb. On Browserbase, you pay for browser time, billed by the minute with a one-minute minimum per session, whether or not the task succeeds.

Which one works with Claude Code, Cursor or ChatGPT?

AgentWeb is added with one command in Claude Code, and any MCP client, including Cursor, Codex and ChatGPT, can add the same server URL. Your agent then calls actions directly. Browserbase's MCP server gives an MCP client a browser to drive with natural language through Stagehand.

Is AgentWeb ready for enterprise?

AgentWeb offers an Enterprise plan for companies running it inside their own product: custom volume pricing and terms, a performance SLA, custom action maps for private software, advanced usage insights, and dedicated support with migration help.
