7 Best Kitesurf Alternatives in 2026
Cloudflare launched Kitesurf on August 6, 2026 with a genuinely different answer to agent browsing: stop giving every agent a full copy of Chromium. Kitesurf runs in V8 isolates on Cloudflare Workers, speaks the Chrome DevTools Protocol, and implements the parts of the browser that agents need without carrying everything built for a human at a screen.
That makes it dramatically lighter. In Cloudflare’s 14-page test, Kitesurf used 3.1 to 3.8 times less CPU and 4.7 to 7 times less memory than warm Chromium for screenshots and HTML extraction. It was also 1.7 to 1.8 times slower by wall clock. That trade is the product: more agent sessions per machine, at the expense of some speed and browser fidelity.
Kitesurf is free while in beta inside Browser Run. It already passes more than 215,000 Web Platform Tests and works with Puppeteer, Playwright, CDP clients, and Cloudflare’s MCP interface. But it is days old, not a drop-in replacement for Chromium on every site, and Cloudflare explicitly says slightly wrong CSS and imperfect rendering are acceptable for its target workload.
Here are the alternatives that solve the same infrastructure problem, from closest substitute to deliberate change of approach.
Kitesurf alternatives at a glance
| Alternative | Browser engine | Managed cloud | Self-host option | Best for |

| Browserbase | Chromium | Yes | Enterprise private cloud | Production developer experience |
| Steel | Chromium | Yes | Yes | Open-source portability |
| Browserless | Chromium, Firefox, WebKit | Yes | Commercial | Mature browser-as-a-service |
| Browser Use Cloud | Chromium plus agent framework | Yes | Framework only | Goal-driven browser agents |
| Playwright or Puppeteer | Chromium and other engines | No | Yes | Maximum control and deterministic flows |
| Carly | APIs rather than pages | Yes | No | Workflows where the target has an API |
1. Cloudflare Browser Run with Chromium
The closest alternative is already in the same product. Browser Run can give your agent a full headless Chrome session on Cloudflare’s network, controlled through Puppeteer, Playwright, CDP, REST quick actions, or MCP. Kitesurf is a new engine option behind those same interfaces.
Choose Chromium when correctness matters more than density: complex authenticated apps, browser extensions, exact rendering, long interactive sessions, downloads, or pages that depend on less common web-platform behavior. Browser Run also adds Live View, recordings, human intervention, and reusable sessions. Its default paid-plan limit reaches 120 concurrent browsers, with higher limits available by request.
vs. Kitesurf: the API and vendor stay familiar; the resource profile changes. Kitesurf is stateless wherever possible and optimized for screenshots and extraction. Chromium carries more overhead but gives you the browser compatibility the public web assumes.
Best for: teams already on Workers that need full Chrome for the hardest pages.
2. Browserbase
Browserbase is managed browser infrastructure built around real browsers. Point Playwright, Puppeteer, Selenium, Stagehand, or a CDP client at its endpoint and it handles browser fleets, session persistence, proxies, CAPTCHA solving, recordings, and observability.
The Free plan includes three concurrent browsers and one browser hour. Developer is $20/month for 25 concurrent browsers and 100 included hours; Startup is $99/month for 100 concurrent and 500 hours. Scale adds custom limits, SSO, HIPAA support, and enterprise controls.
vs. Kitesurf: Browserbase is the safer choice when production means arbitrary third-party sites and Chrome compatibility is non-negotiable. Kitesurf should be far cheaper to operate at massive concurrency, but its beta engine has a deliberately smaller fidelity target. Browserbase is also cloud-first; it is not the open-source escape hatch that Steel is.
Best for: engineering teams that want the polished managed-Chromium option.
3. Steel
Steel is open-source browser infrastructure under Apache-2.0. It runs Chromium behind Playwright, Puppeteer, Selenium, CDP, and its own SDKs, and can be self-hosted with Docker or consumed from Steel’s cloud. CAPTCHA solving, proxies, session management, recordings, and anti-bot tooling sit at the infrastructure layer.
Its Launch plan has no monthly fee, starts with a one-time $30 usage credit, and supports 10 concurrent 15-minute sessions. Scale is $250/month plus usage for 100 concurrent one-hour sessions and $100 in monthly usage credit. Enterprise supports 1,000-plus concurrent sessions, reserved pools, stealth features, and SLAs.
vs. Kitesurf: Steel gives you Chromium fidelity plus a credible self-host path. Kitesurf gives you the lighter architecture and Workers-native scale. If avoiding infrastructure lock-in is the deciding factor, Steel wins; if running huge bursts of disposable extraction jobs is the deciding factor, Kitesurf is the more interesting bet.
Best for: teams that want open-source browser infrastructure they can take home.
4. Browserless
Browserless is one of the mature browser-as-a-service platforms. It supports Playwright and Puppeteer connections, Chrome, Firefox, and WebKit, plus REST APIs for common jobs, session reconnects, recordings, residential and data-center proxies, and automatic CAPTCHA solving.
Pricing uses 30-second units. The free plan includes 1,000 units and two concurrent browsers; paid plans begin at $25/month billed annually for 20,000 units and 10 concurrent browsers. Enterprise adds private deployments or licensed self-hosting, persistent sessions, custom proxy limits, and larger concurrency.
vs. Kitesurf: Browserless is broad and conventional. You get real browser engines and mature operational features, while Kitesurf strips away browser machinery that agents may not need. Browserless is better for mixed automation workloads; Kitesurf is better aligned with stateless, machine-readable jobs on Workers.
Best for: teams that want a mature multi-engine browser service with private deployment options.
5. Browser Use Cloud
Browser Use combines an open-source agent framework with managed browsers. Instead of writing each interaction, you give the agent a goal and let its harness observe the page, plan actions, recover when the UI shifts, and complete the task. The cloud adds stealth browsers, CAPTCHA solving, proxies, scheduled jobs, webhooks, and hosted execution.
vs. Kitesurf: these sit at different layers. Kitesurf is an engine; Browser Use is an agent harness plus infrastructure. Pick Browser Use when your unsolved problem is deciding what to click next. Pick Kitesurf when you already have an agent and the unsolved problem is giving thousands of runs an efficient browser.
The Browser Use framework is MIT licensed and can run against other browser providers. That also means you can test a layered setup rather than treating this as a permanent either-or decision.
Best for: teams that need agent reasoning and recovery, not only browser capacity.
6. Playwright or Puppeteer, self-hosted
Running Playwright or Puppeteer on your own machines remains the control case. Both are open source, deterministic, and free apart from compute. Playwright gives you Chromium, Firefox, and WebKit; Puppeteer is most closely associated with Chrome and the DevTools Protocol.
vs. Kitesurf: self-hosting gives you exact version control, custom browser flags, extensions, local networking, and no infrastructure vendor. It also gives you cold starts, memory leaks, browser patching, queue management, crashed-session cleanup, and the bill for idle capacity. Kitesurf exists because assigning a full browser process to every bursty agent job is expensive.
Start here when the workload is small, predictable, or unusually customized. Move to a browser service when operating the fleet becomes the work.
Best for: stable flows and teams that need complete runtime control.
7. Carly, when the website has an API
The cheapest browser session is the one you never launch. If the job is “read a lead email, update HubSpot, create an invoice in QuickBooks, and send a reply,” browser automation is an indirect route through interfaces that were built for people.
Carly runs that kind of work through native integrations and public APIs. Around 260 apps connect directly, and anything else with a public API can connect with your own key. Agents can run on a schedule, react to incoming mail, and work through their own email address. There is no DOM, proxy, CAPTCHA, or browser state in the path.
vs. Kitesurf: Carly is a finished automation platform, not browser infrastructure. It will not help with a login-walled portal that exposes no API. Where an API exists, it removes the fragile browser layer entirely.
Pricing: free Zapier-style workflows; AI agents from $35/month.
Best for: business workflows across SaaS tools, email, calendars, and CRMs.
Which Kitesurf alternative should you choose?
Stay with Cloudflare Browser Run’s Chromium engine if Kitesurf fails on one of your target pages. It is the smallest architectural change and lets you route light jobs to Kitesurf while reserving Chromium for the hard ones.
Choose Browserbase for the strongest managed developer experience around real Chrome. Choose Steel when open source and self-hosting matter. Choose Browserless when you want a mature service with multiple browser engines and private deployment options.
Choose Browser Use Cloud when the browser works but your agent needs a better planning and recovery loop. Self-host Playwright or Puppeteer when volume is manageable and total control is worth the operational burden.
And check the target system for an API before committing to any browser stack. Browser Use alternatives compares the agent frameworks and cloud-browser services in more depth, while AI browser automation tools maps the wider category.
Kitesurf is unusually promising precisely because it does not pretend to be Chrome. Its beta question is not whether it can render every page perfectly. It is whether the subset it renders well covers enough high-volume agent work to justify a second engine in production. Run your own test corpus before choosing: the median on fourteen URLs cannot tell you how your fourteen URLs behave.
FAQ
What is Cloudflare Kitesurf?
Kitesurf is a browser engine built specifically for AI agents. It runs in V8 isolates on Cloudflare Workers instead of launching Chromium, speaks CDP for compatibility with tools such as Playwright and Puppeteer, and is available through Browser Run. It is free while in beta.
Is Kitesurf a Chromium browser?
No. Kitesurf implements its own agent-focused browser architecture using Rust, WebAssembly, Workers, and parts of the Blitz rendering engine. It supports core web capabilities and CDP clients, but does not promise pixel-perfect Chromium compatibility.
What is the best Kitesurf alternative?
Cloudflare Browser Run with Chromium is the closest replacement because the provider and control interfaces stay the same. Browserbase is the strongest polished managed option, Steel is the open-source option, and self-hosted Playwright is the maximum-control option.
Is Kitesurf faster than Chromium?
Not by wall-clock time in Cloudflare’s launch test. Kitesurf was about 1.7 to 1.8 times slower for HTML extraction and screenshots, but used 3.1 to 3.8 times less CPU and 4.7 to 7 times less memory. Its advantage is compute efficiency and concurrency, not single-job speed.
Can Kitesurf use Playwright and Puppeteer?
Yes. Kitesurf exposes Chrome DevTools Protocol WebSocket and REST interfaces, so existing Playwright, Puppeteer, chrome-remote-interface, MCP, and CDP-based clients can point to it through Browser Run.

"Before Carly, I relied on a Calendly link, but the whole process felt impersonal and not very professional. Carly changed that by handling all the back-and-forth, so I'm no longer stuck in endless email threads trying to line up schedules.
Now Carly reaches out to candidates, shares my real-time availability, lets them pick a slot, then sends a Zoom link and drops it straight into my calendar. She sends reminders to both of us before each call, which has significantly reduced no-shows and last-minute confusion.
On top of scheduling, Carly acts like a full executive assistant, sending me my schedule the night before so I can prepare for each call. It reminds me of the old x.ai assistant, but Carly is noticeably smarter, faster, and better suited to my healthcare recruitment business."
