Browserbase Alternatives: 9 Cloud Browsers for Agents

The best Browserbase alternative depends on why you're leaving. If you want to self-host, Steel is the cleanest open-source swap. If you want a sandbox and a browser under one bill, look at Hyperbrowser. If you need logged-in agents with compliance paperwork, look at Anchor or Kernel. If blocked sites are the problem, look at Bright Data's Browser API. If you want a cheap browser on your own servers, run Lightpanda or plain Playwright.

One thing to settle first: you may not need to leave Browserbase's code at all. Stagehand, Browserbase's own agent SDK, is MIT-licensed and can drive a local browser. So "leave Browserbase" and "rewrite your Stagehand code" are two separate decisions.

This guide is about browser infrastructure, the hosted Chrome your agent connects to. If you're comparing agent frameworks instead, see our Browser Use alternatives guide. If you only need page text for a model, see Firecrawl alternatives.

What Browserbase Does, and Why Teams Look Elsewhere

Browserbase started as cloud browsers for agents and has grown into a full platform. Its docs list hosted browser sessions, Search and Fetch APIs, Functions that deploy your agent next to the browser, an Agent Identity layer for anti-bot systems and login walls, and a Model Gateway. Every session gets logs, live view and replays.

The open-source pieces are Stagehand, which adds act, extract and observe primitives on top of Playwright-style control, and the Browse CLI.

Billing is a monthly plan with included browser hours, proxy data and API calls, with extra usage billed at your plan's rate. Higher plans unlock more concurrency, longer data retention and stronger anti-bot features.

So the usual reasons to look around are:

• You want to run browsers yourself. Browserbase is a hosted service.
• Your cost driver is different. If most of your bill is proxy traffic, or browsers that sit idle, a different billing model can fit better.
• You need a sandbox too. Agents that write code and browse the web may want both under one API.
• You need compliance features like HIPAA agreements or bring-your-own-cloud on a smaller contract.
• You're doing plain scraping. A full agent platform is more than you need.

Quick Comparison

The Best Browserbase Alternatives

Steel: the open-source swap

Best for: teams that want to self-host, or keep a managed option with the same API.

Steel is the closest like-for-like replacement. Its Sessions API starts a real browser per session, and you point Puppeteer, Playwright or Selenium at it by changing one connect URL. Sessions can carry cookies and state into the next run, profiles persist across runs, and a live viewer lets a human step in for 2FA or payments, then hand control back to the agent.

The engine is Steel Browser, Apache-2.0, which runs from a single Docker image. Its README carries one warning worth repeating: the default ports have no authentication, so never expose them to the public internet.

Steel Cloud bills a plan plus usage. The pricing page meters browser hours, proxy bandwidth and CAPTCHA solves separately, and session length grows with the plan, up to 24 hours on Enterprise.

Where it's weaker than Browserbase: fewer extras around the browser. There's no equivalent of Browserbase's Functions or Model Gateway, so you host your agent somewhere else.

Hyperbrowser: browsers plus sandboxes

Best for: agents that browse and run code in the same workflow.

Hyperbrowser bundles four products under one API: cloud Chrome sessions, isolated sandbox VMs with memory snapshots, a Web API that returns Markdown, HTML, screenshots or schema-matched JSON, and hosted agents. You can run tasks with its own HyperAgent, with Browser Use, or with computer-use models.

Billing is a monthly credit pool that you spend across all four products, so a quiet month for browsers can go to sandboxes instead. HyperAgent, its open-source agent framework, is AGPL-3.0.

Where it's weaker than Browserbase: the browser product is less of a standalone focus, and there's no self-host route. If you only need a code sandbox, our Daytona alternatives guide covers dedicated options.

Browserless: for scripts you already have

Best for: teams with a pile of Puppeteer or Playwright scripts that keep crashing.

Browserless has been running hosted browsers since before AI agents were a category. The pitch is a one-line swap: replace launch() with connect() and your existing script runs on its fleet. On top of that it offers BrowserQL, an MCP server, CAPTCHA solving, residential proxies, and profiles that persist. Its plans include Chrome, WebKit and Firefox.

The difference from most of this list is deployment. Browserless offers its own cloud, a managed cloud, or your own hardware, with the same API in each. But read the license before you self-host. It's dual-licensed under SSPL or a commercial license, and the README says closed-source commercial use needs the commercial license.

Where it's weaker than Browserbase: it's browser infrastructure first. You bring the agent framework.

Anchor: logged-in agents with compliance needs

Best for: agents that work inside customer accounts, in fields like healthcare or finance.

Anchor focuses on authentication. Its OmniConnect product handles the login lifecycle for computer-use agents, and its own Chromium fork is built to be recognized as a human browser. Anchor also describes a built-in VPN, so you aren't relying only on third-party proxies.

Its plans include credits plus usage for browser time and proxy traffic. The enterprise tier lists HIPAA, a BAA, SSO, custom regions, and both bring-your-own-cloud and on-premise deployment.

Where it's weaker than Browserbase: less open tooling. Anchor doesn't publish an open-source SDK comparable to Stagehand.

Kernel: fast starts and memory-based billing

Best for: agents that open lots of short sessions and need them ready right away.

Kernel runs sandboxed Chromium that Playwright and Puppeteer connect to over CDP, with live view, MP4 session recordings, managed auth, CAPTCHA handling and regional browsers. Higher plans add GPU acceleration for canvas-heavy sites. The browser images behind its hosted service are open source as kernel-images, under Apache-2.0.

The billing model is the main difference. The pricing page charges usage per GB-second of memory, says there are no charges for idle time or proxies, and puts that on top of a monthly plan.

Worth reading before you sign: Kernel published a security incident notice on November 4, 2026. It says an attacker used a compromised API key, reached its logging provider and some servers, and that the breach affected 0.28% of customers. It also lists the steps Kernel took. Read the notice yourself as part of your vendor review.

Bright Data Browser API: when sites keep blocking you

Best for: data collection on JavaScript-heavy sites with aggressive bot detection.

Bright Data's Browser API, formerly called Scraping Browser, runs your Puppeteer, Playwright or Selenium code on hosted browsers. Bright Data handles proxy rotation across its networks, including residential IPs, plus fingerprint management, CAPTCHA solving and retries.

You pay per GB of traffic rather than per hour or per request, and the product page lists unlimited concurrent sessions. That makes it cheap for long sessions on light pages, and expensive on media-heavy ones.

Where it's weaker than Browserbase: it's built for data collection, not for agents acting inside accounts. There's no agent SDK in the box.

Apify: scrapers you schedule and reuse

Best for: recurring extraction jobs, or teams that would rather run a ready-made scraper than write one.

Apify runs Actors: serverless programs that take JSON input, run a browser or HTTP job, and return structured output. You can run them on a schedule, through the API, or from an AI agent over MCP. Many are published in Apify Store. Its open-source library Crawlee (Apache-2.0) handles Playwright, Puppeteer and proxy rotation, and runs anywhere.

Billing is a monthly plan with prepaid usage, then compute units, proxy and storage, or per-event pricing set by each Actor's author.

Where it's weaker than Browserbase: it's a job platform, not a live browser your agent drives step by step. For a full comparison, see our Apify alternatives guide.

Lightpanda: a lighter engine, not a lighter Chrome

Best for: high-volume headless runs where Chrome's memory is the bill.

Lightpanda is a browser written from scratch in Zig, not a Chromium fork. It runs JavaScript but does no graphical rendering. In its own benchmark of 100 pages on an AWS m5.large, it used about 16x less peak memory and ran about 9x faster than headless Chrome. It exposes a CDP server, so Puppeteer and Playwright scripts connect to it like any other browser. It's AGPL-3.0, and version 1.0 is out.

Where it's weaker than Browserbase: no real rendering means screenshots are text-only, and sites that depend on visual layout or rare web APIs may break. Test your target sites first. There's a cloud offer if you don't want to host it.

Self-hosted Playwright: no vendor at all

Best for: internal tools, low volume, and sites that don't fight back.

Playwright can launch Chromium, Firefox or WebKit, or connect to any CDP endpoint. Run it in containers on your own servers and you pay only for compute. Stagehand also runs on a local browser, so your agent code can stay the same.

What you give up: everything the vendors sell. Proxies, CAPTCHA handling, session replays, scaling and Chrome upgrades become your job. If your agent works in an editor, the Playwright MCP server is a quick way to give it a local browser.

How to Choose a Browserbase Alternative

Then run the same test on each shortlist option: your hardest target site, a logged-in flow, and a session long enough to hit the plan's time limit. Cold start and success rate on your sites matter more than anyone's benchmark.

Whichever you pick, check each site's terms of service and robots.txt before you automate it. Anti-bot features don't change what a site allows.

Where Browserbase Is Still the Right Call

Stay on Browserbase if:

• You use Stagehand heavily. It's Browserbase's own SDK, and the Model Gateway and Functions are built around it.
• You want one platform. Browsers, search, fetch, agent hosting and model access under one key and one bill is hard to rebuild.
• You debug a lot. Logs, live view and replays across every agent step save real time.

Where Taku Fits

Taku doesn't host browsers, and it isn't an alternative to anything here. But if you're wiring agents to browsers because the app is where AI keeps getting stuck, this is the bet Taku is making. Most AI lives inside an app. Taku OS builds it into the operating system, so it can work across your apps, camera, sensors and the devices around you. AI belongs in the OS. The OS belongs to you.

FAQ

What are the main Browserbase competitors?

Steel, Hyperbrowser, Browserless, Anchor and Kernel are the closest. Bright Data's Browser API and Apify compete on the data-collection side. Lightpanda and self-hosted Playwright are the do-it-yourself options.

What is the best open source Browserbase alternative?

Steel Browser, which is Apache-2.0 and runs from one Docker image. Lightpanda (AGPL-3.0) is a lighter engine for headless work. Browserless can be self-hosted too, but under SSPL or a commercial license.

Is there a cheaper alternative to Browserbase?

It depends on what drives your bill. Kernel charges for active memory and includes proxies. Bright Data charges per GB of traffic. Self-hosted Steel, Lightpanda or Playwright cost only your servers, plus the time to run them. Compare each vendor's pricing page against a week of your real usage.

Can I use Stagehand without Browserbase?

Yes. Stagehand is MIT-licensed, and its README shows it launching a local browser with a saved profile. Browserbase adds hosted sessions, replays and the Model Gateway on top.

Browserbase vs Steel: which is better?

Pick Steel if you want to self-host or keep the option open, since its engine is Apache-2.0. Pick Browserbase if you want the larger platform around the browser: Search, Fetch, Functions and the Model Gateway.
