Browserbase vs Browser Use: Which One Should Your Agents Run On? (2026)

Browserbase and Browser Use both put cloud browsers behind an AI agent, so they turn up on the same shortlist, but they start from opposite ends. Browser Use leads with the agent and sells the browser time underneath it; Browserbase leads with the browser and builds a platform around it. Picking the wrong one usually shows up later, as a rewrite of the agent loop or a bill shaped differently than expected.

This blog belongs to TestMu AI (formerly LambdaTest), whose Browser Cloud competes with both products. Every Browserbase and Browser Use fact below comes from their own pricing pages, docs and GitHub repositories.

What Are Browserbase and Browser Use?

Browser Use started as an open-source library that lets an LLM drive a real browser. Its GitHub repository lists an MIT license and about 120,000 stars on November 5, 2026. The company also sells Browser Use Cloud: hosted agents you call by API, and cloud browsers you drive over CDP with your own code. In March 2025 it closed a $17 million seed round led by Felicis, which TechCrunch reported as Browser Use raises $17M.

Browserbase is a managed browser fleet for agents. Around it sit Stagehand (its MIT-licensed agent SDK, about 26,000 GitHub stars, in TypeScript, Python and Go), Director (natural-language instructions to Stagehand code), the browse CLI for coding agents, and the Search, Fetch, Functions and Model Gateway APIs. In June 2025 it closed a $40 million Series B led by Notable Capital, which SiliconANGLE reported as Browserbase reels $40M.

Browserbase vs Browser Use: Key Differences

Browserbase figures come from its pricing page and docs. Browser Use figures come from its pricing page, which says its prices were last verified against its billing service on September 3, 2026, and from its docs.

Which Is Cheaper, Browserbase or Browser Use?

On browser time, Browser Use, by a wide margin on list price. Its pricing page charges $0.02 an hour, billed per minute. Browserbase's pricing page includes 100 hours in the $20 Developer plan and 500 in the $99 Startup plan, then charges $0.12 or $0.10 per extra hour.

The rows use list prices from both pricing pages on November 5, 2026. Browser hours are rarely the whole bill, though:

• Proxy traffic - Browser Use turns on its residential proxy by default at $5 per GB, and Browserbase charges $10 to $12 per GB after the included allowance. At an illustrative 5 MB per task, that is 2.5 cents on Browser Use and 5 to 6 cents on Browserbase.
• Model tokens - Browser Use's hosted agents bill model cost plus 20%. On Browserbase you pay your model provider directly, or use Model Gateway at market price.
• Concurrency you can count on - Browser Use unlocks concurrency by lifetime spend, so 250 sessions need $1,000 paid to date. Browserbase gives 100 on the $99 Startup plan from day one.

Plan detail and more worked bills are in Browserbase pricing.

Which Handles Bot Detection Better?

Browser Use includes stealth browsers, residential proxies and CAPTCHA solving with every cloud browser. Its pricing page reports its own benchmark: 90.5% on Stealth Bench V2 and 84.8% on BrowserBench, with a note that the 100 Stealth Bench sites were picked where Browser Use Cloud historically got through, so the sample is not balanced.

Browserbase ties stealth to the plan: none on Free, Basic on Developer and Startup, Advanced on Scale, with automatic CAPTCHA solving on the paid plans and verified agents on Scale. Its blog announced identity partnerships with 1Password on October 22, 2026 and Okta Cross App Access on September 22, 2026.

Neither benchmark is independent. Before you commit, run your 20 hardest target sites on both and count the blocks.

Which Is Easier to Build With?

Browser Use is faster to a working agent. You give the library a task in natural language and a model; it plans, clicks and reads. Its README shows that moving from a local browser to a Browser Use Cloud browser is one setting, Browser(use_cloud=True).

Browserbase gives you more control over each step. Stagehand lets you write Playwright-style code and call AI only where you need it, through act, extract and observe, which tends to make runs more repeatable. Director writes Stagehand code from natural-language instructions if you want a head start, and Functions deploys the agent next to the browser.

A Python team prototyping an autonomous agent will usually reach a demo sooner with Browser Use. A TypeScript team shipping a workflow that has to behave the same way every time usually fits Stagehand on Browserbase better; the Stagehand alternative page covers that framework choice on its own.

How Do Sessions and Limits Compare?

• Browserbase - its timeouts doc sets a 6-hour maximum session (15 minutes on Free), with keep-alive for reconnecting to the same browser, and its multi-region doc lists Oregon (the default), Virginia, Frankfurt and Singapore.
• Browser Use Cloud - its create-browser-session doc sets a 60-minute default timeout that all users can raise to 240 minutes (4 hours). The docs also note that closing a CDP connection doesn't stop a browser, so stop it explicitly when the task ends.

For agents that idle between steps, the gap matters: a 4-hour cap means a long research task on Browser Use has to checkpoint and resume, while Browserbase leaves two more hours of headroom.

Can You Use Browserbase and Browser Use Together?

Yes. The Browser Use README says the library can control "an existing remote browser over CDP", and Browserbase's docs include a Browser Use integration guide for Python projects. Teams combine them when they want Browser Use's agent loop with Browserbase's regions, fixed concurrency or compliance terms.

A Third Option: TestMu AI Browser Cloud

TestMu AI makes Browser Cloud, so weigh this section accordingly. It fits a narrower case than either product above: agents or QA runs that have to reach localhost, staging or VPN-only apps through its built-in tunnel, and teams that want agent runs and cross-browser QA on the same cloud that runs 1.5 billion tests a year for 18,000+ enterprises.

Kane CLI pairs with it: it can drive a remote browser, such as a Browser Cloud session, through its --ws-endpoint or --cdp-endpoint option (Kane CLI CLI reference) and returns a pass or fail exit code for CI. Browser Cloud is less of a fit if you need a Python SDK, a published per-hour price, or search and fetch APIs, which it doesn't offer today. The head-to-head with Browserbase is in Browser Cloud vs Browserbase.

Browserbase or Browser Use: Which Should You Pick?

Decide on how you want to build the agent first, then check the bill against your expected hours and concurrency.

Conclusion

Write down whether your agent should decide its own steps or follow steps you script, then price your real monthly hours and peak concurrency on both pricing pages. If the agent also has to reach apps behind your firewall, try the tunnel on Browser Cloud with the What is Browser Cloud guide.
