BrowserBash.

BrowserBash

BrowserBash is a free, open-source natural language browser automation CLI that transforms plain English objectives into real browser tests. An AI agent drives an actual browser session without requiring selectors, code, or brittle locators — enabling anyone to automate complex web workflows using simple sentences. Run entirely on free local models via Ollama or free OpenRouter models with zero API keys and no credit card required.

Product Highlights

• Natural Language Automation: Write browser tests in plain English — no selectors, no code, no flaky locators needed. Simply describe what you want the browser to do.
• 100% Free to Run: Default stack uses free local Ollama models and open-source Stagehand engine — no API keys, no metered usage, no cloud costs.
• Real Browser Execution: Drives actual Chrome sessions with full session persistence, video recording, and per-run replay for complete transparency.
• CI-Native Design: Outputs NDJSON events to stdout with standardized exit codes (0/1/2/3) — built for pipelines, not just demos.
• Cloud-Neutral Architecture: Run locally on your Chrome or swap to Browserbase, LambdaTest, BrowserStack, or any CDP endpoint with a single flag.
• Privacy-First by Default: Nothing leaves your machine unless you explicitly add --upload — runs are local, private, and unmetered.
• Open Source Stack: Apache-2.0 CLI with MIT-licensed engine — fully auditable, forkable, and extensible.

Use Cases

• End-to-End Test Automation: Replace fragile Playwright or Selenium suites with readable, committable markdown test files that describe user journeys in plain English.
• CI/CD Pipeline Integration: Embed natural language browser tests directly into GitHub Actions with deterministic exit codes and no prose parsing required.
• Agentic Workflow Orchestration: Power AI agents and autonomous systems with structured browser automation that streams real-time progress via NDJSON.
• Cross-Browser Cloud Testing: Execute the same objective across local Chrome and enterprise grids (BrowserStack, LambdaTest) without rewriting tests.
• Session-Based Data Extraction: Maintain authenticated sessions across multi-step workflows to scrape data, fill forms, or verify checkout flows.

Target Audience

BrowserBash is designed for QA engineers, DevOps teams, and AI developers who need reliable browser automation without the overhead of traditional frameworks. It particularly serves organizations seeking to reduce test maintenance burden, eliminate vendor lock-in, and run automation entirely on free, private infrastructure.
