Web Agents (Browser Use) alternative that returns a verdict
Kane CLI is the Web Agents alternative that adds a verdict. Extract, automate, and test in natural language, then get a real pass or fail with video evidence and clean CI exit codes. Browser Cloud scales it. Free to install.

Why teams move from Web Agents to Kane CLI
Web Agents lets you extract, automate, test, and monitor in natural language, which is the closest functional overlap with Kane CLI. The gap is the contract: testing in natural language is only as useful as the verdict it produces, and a verdict is exactly what Web Agents leaves implicit.
Kane CLI leads with that verdict: natural-language objectives drive a real browser, self-heal when the UI changes, and return a real pass or fail with video evidence and CI exit codes. Extraction lands in final_state, so the same flow tests and extracts.
For monitoring at scale, Browser Cloud provides the parallel real-browser sessions, and Kane CLI runs the recurring checks on them.
Kane CLI vs Web Agents
Both extract, automate, and test in natural language. Kane CLI adds the verified pass or fail.
| Capability | Kane CLI + Browser Cloud | Web Agents |
|---|---|---|
| Automate in natural language | Natural-language objectives | Natural-language automation |
| Extract in natural language | store-as extraction into final_state | Natural-language extraction |
| Test in natural language | Verified pass or fail, the part they lack | Tests, no verdict contract |
| Monitor | Recurring runs and CI; Browser Cloud for scale | Monitoring |
| Model and API keys | Managed model, nothing to configure | Platform-managed |
| Evidence | Video, step trace, shareable links | Run output |
| Native Playwright export | One command |
What you get with Kane CLI
Extract, automate, and test in natural language, now with a verdict.
No code, no keys
Skip the SDK wiring and the model and API key setup. Install one CLI, describe the journey in natural language, and Kane CLI drives a real browser with a managed model.
Resilient by default
When the frontend changes, Kane CLI adapts on its own, pushing through up to 50 steps until the full journey is verified instead of breaking on a moved element.
Verified pass or fail
Built-in assertions check each step, not just the final screen, and flag the exact point of failure. A real result, not raw agent output to parse.
Replay and caching
Validated flows replay from a cached test.md with no repeat LLM cost, so re-running the suite in CI does not keep burning tokens.
Cross-browser cloud and CI
Scale to cross-browser and cross-OS runs on the TestMu AI grid with one flag, and gate pipelines on clean exit codes from your terminal.
Own the Playwright code
Export any validated flow to native Playwright with one command, then modify and own it. The convenience never locks you in.
Build up confidence locally

Validate on the cloud
Release with confidence
Scale on Browser Cloud
Need the browsers too? Browser Cloud is the TestMu AI infrastructure layer: real, full-featured Chrome sessions on demand at scale, with a built-in tunnel to localhost and staging, full session transparency, persistent state, and best-effort stealth.
Install it with npm install @testmuai/browser-cloud. Kane CLI connects to Browser Cloud sessions over --ws-endpoint, so the same natural-language flow runs on real cloud browsers and scales across them.
Browser Cloud is the browsers. Kane CLI is the natural-language verification that runs on them and returns a pass or fail.
From prototype to production, on one engine
Kane CLI and KaneAI share the same automation engine and dashboard.
Prototype to production
Open-source agents and SDKs are great for prototyping. Kane CLI is the production-grade, test-focused path: assertions, caching, evidence, and CI built in.
Built for the agent loop
Generate code, then verify it in a real browser before opening a PR. Kane CLI closes the gap between what an agent writes and what works.
Evidence you can share
Every run produces a persistent video, step trace, and replay link to drop into a PR or bug report, backed by a dashboard your team can browse.
Replace Web Agents in three steps
Install
Run npm install -g @testmuai/kane-cli, then sign in with your TestMu AI account. No project to scaffold and no API keys to manage.
Describe the flow
Tell Kane CLI what to do in natural language, or point your AI coding agent at the agent guide and let it drive the browser.
Run and verify
Kane CLI drives a real browser, verifies each step, and returns a pass or fail with video proof. Re-runs replay from cache with no repeat LLM cost.

Frequently asked questions
Kane CLI by TestMu AI is the leading Web Agents alternative. Web Agents extract, automate, test, and monitor in natural language, but stop short of a verdict. Kane CLI adds a real pass or fail with video evidence and CI exit codes, self-heals, and extracts into final_state, and it scales on Browser Cloud for monitoring across many real browsers.
Web Agents, from Browser Use, let you extract, automate, test, and monitor in natural language. They cover the same surface as Kane CLI, but without a deterministic pass or fail contract for the testing use case.
Kane CLI leads with the verdict: natural-language objectives return a real pass or fail with video and CI exit codes, self-heal with confidence-scored matching, replay from a cached test.md with no repeat LLM cost, and export to native Playwright with one command.
Yes. Browser Cloud is cloud browser infrastructure for AI agents: real Chrome at scale with a built-in tunnel, full session transparency, and best-effort stealth. Kane CLI runs recurring checks on Browser Cloud sessions over --ws-endpoint, so monitoring fans out across many real browsers.
Teach your agent the right skills
Point your AI coding agent at the Kane CLI guide and it will install, authenticate, and run verified browser flows on its own, no SDK or API keys required.
