What is the best Browserbase alternative?

Browser Cloud by TestMu AI is the leading Browserbase alternative for AI agents. It maps one to one onto the Browserbase platform: real Chrome sessions on demand, session transparency in place of Observability, session persistence in place of contexts, and best-effort Stealth Mode in place of Identity, plus a built-in tunnel to localhost and staging that Browserbase does not lead with. For the automation layer that Browserbase users reach through Stagehand, Kane CLI adds natural-language flows that return a verified pass or fail, with no code.

How does Browser Cloud compare to Browserbase for browser infrastructure?

Both provide cloud browser infrastructure for AI agents with Playwright, Puppeteer, and Selenium support. Browser Cloud adds a built-in tunnel to reach localhost and private apps, full session transparency for debugging, session persistence, 180+ geolocations, and broader enterprise compliance (SOC 2 Type II, ISO 27001, PCI DSS, HIPAA, GDPR, CCPA), backed by the cloud that runs 1.5 billion tests a year for 18,000+ enterprises.

Is there a no-code alternative to Stagehand for natural language browser automation?

Yes. Kane CLI is the no-code answer to Stagehand. Instead of wiring an SDK and model keys, you give Kane CLI a plain-English objective and it drives a real browser, self-heals when the UI changes, and returns a verified pass or fail with shareable video. It runs on Browser Cloud sessions over --ws-endpoint, so the same flow scales across real browsers.

Can Browser Cloud reach localhost or private environments?

Yes. The built-in tunnel connects cloud sessions to apps on localhost, staging, internal dashboards, or anything behind a VPN, with no third-party tunneling service to set up. Any non-public target uses the tunnel.

What is Browser Cloud?

Browser Cloud is scalable browser infrastructure for AI agents, built by TestMu AI. It provides real, full-featured Chrome sessions on demand, with built-in parallelism, a tunnel for local and private environments, session persistence, best-effort Stealth Mode, and full session transparency, so Claude, Cursor, Gemini, OpenAI Computer Use, and custom agents can act on the live web.

Does Browser Cloud support Playwright, Puppeteer, and Selenium?

Yes. Browser Cloud drives sessions with Playwright, Puppeteer, or Selenium, with no proprietary DSL. If you already use any of these frameworks, switching is a connection string change while your existing automation logic stays the same.

Enterprise Browserbase alternative for AI agents

Add natural-language verification with Kane CLI

Browserbase users reach for Stagehand to automate. Kane CLI is the no-code answer: a plain-English objective drives a real browser and returns a verified pass or fail.

Explore Kane CLI

Kane CLI runs on the same Browser Cloud sessions and returns a verified pass or fail, so your agent ships proof, not just output.

Plain-English objectives drive a real browser, with no code and no model or API keys to wire up
Self-heals when the UI changes, then returns a verified pass or fail with shareable video proof
Clean CI exit codes (0 pass, 1 fail, 2 setup, 3 timeout) and one-command native Playwright export
Runs on Browser Cloud sessions over --ws-endpoint, so the same flow scales across real browsers

Browser Cloud is the browsers. Kane CLI is the verification.

Browser Cloud is the browsers. Kane CLI is the natural-language verification layer that runs on them. Point Kane CLI at a Browser Cloud session with --ws-endpoint, and a plain-English objective drives that real Chrome and returns a verified pass or fail.
