Production-grade BrowserBash alternative
Kane CLI is the production-grade BrowserBash alternative. The same plain-English CLI, plus a managed model with no setup, autoheal, a verified pass or fail with video, and one-command native Playwright export. Free to install.

Why teams move from BrowserBash to Kane CLI
BrowserBash is the closest positional twin to Kane CLI: a free, open-source, plain-English browser automation CLI that drives a real browser, returns exit codes for CI, runs on local or OpenRouter models, and connects to local Chrome or any grid. If you like that shape, you will recognize Kane CLI.
Kane CLI is the production-grade version. A managed model means no Ollama or OpenRouter setup and no per-token cost. Add autoheal plus cached replay, a verified pass or fail with built-in assertions and shareable video, Test Manager and a dashboard, one-command Playwright export, and native skills for Claude Code, Codex, and Gemini.
Because BrowserBash connects to grids, Browser Cloud is the natural secondary: the grid plus tunnel plus transparency that Kane CLI can run on.
Kane CLI vs BrowserBash
The same plain-English CLI, with managed reliability and a verdict on top.
| Capability | Kane CLI + Browser Cloud | BrowserBash |
|---|---|---|
| Plain-English CLI | Natural-language objectives in a real Chrome | Plain-English CLI, real browser |
| Model | Managed model, nothing to configure | Bring local or OpenRouter models |
| CI exit codes | 0 pass, 1 fail, 2 setup, 3 timeout | Exit codes for CI |
| Grid connectivity | Remote endpoints; Browser Cloud as native grid plus tunnel | Connects to TestMu AI, BrowserStack, Browserbase |
| Evidence and dashboard | Test Manager, video, step trace, shareable links | Optional dashboard, recordings |
| Managed reliability | Autoheal, cached replay, Playwright export | Open-source agent loop you run |
| Native Playwright export | One command |
What you get with Kane CLI
The same CLI shape, with production reliability built in.
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
Start in your terminal
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 BrowserBash 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 production-grade BrowserBash alternative. BrowserBash is a free, open-source plain-English CLI that you run on local or OpenRouter models. Kane CLI keeps the same shape but adds a managed model with no setup, autoheal, a verified pass or fail with video, a dashboard, and one-command Playwright export, with Browser Cloud as the native grid plus tunnel.
BrowserBash is a free, open-source, plain-English browser automation CLI. An AI agent drives a real browser from one plain-English sentence, runs on free local models or free OpenRouter models, connects to local Chrome or any CDP grid, and returns exit codes for the pipeline, with an optional free dashboard.
Kane CLI is the managed, production-grade version: a managed model so there is no Ollama or OpenRouter setup and no per-token cost, autoheal plus cached replay, built-in assertions with a verified pass or fail, Test Manager and a dashboard, native skills for coding agents, and one-command Playwright export.
Yes. Kane CLI connects to remote browser endpoints over --ws-endpoint, and Browser Cloud is the native grid: real Chrome at scale with a built-in tunnel and full session transparency for Kane CLI to run on.
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.
