Free, open-source CLI that turns plain-English objectives into real browser automation driven by an AI agent on local or cloud models.
BrowserBash is a free, open-source command-line tool that turns a plain-English objective into real browser automation, with an AI agent driving an actual browser instead of brittle selectors or hand-written scripts. It runs on free local models via Ollama or free OpenRouter models, so there are no required API keys and no credit card, though you can bring an Anthropic or OpenRouter key if you prefer. Each run emits a structured NDJSON event stream that CI pipelines and AI agents can consume, and a free account adds a dashboard with run history, video recordings, and per-run replays. Released under the Apache-2.0 license, it is aimed at testers and developers who want natural-language end-to-end tests without flaky locators. You install it with a single npm command and can automate any site in seconds.

BrowserBash is a free, open-source command-line interface (CLI) that transforms plain-English objectives into real browser automation. It utilizes an AI agent, allowing users to automate tasks on local machines or cloud-based models, streamlining workflows and enhancing productivity.
BrowserBash is designed for developers, testers, and anyone needing browser automation without extensive programming knowledge. By using plain English commands, users can easily instruct the AI agent to perform various tasks.
BrowserBash automates browser testing by transforming plain-English commands into executable tests, utilizing free local or cloud models, and streaming structured events for CI integration. It features a dashboard for video replays and is open-source, making it easy to install and use without complex coding.
BrowserBash simplifies the process of end-to-end browser testing by allowing users to write tests in plain English. For example, instead of writing complex code, a user can input a sentence like "Click the login button and enter my username and password." BrowserBash processes this command and executes it in a real browser environment.
It operates using free local or cloud models, such as those provided by Ollama or OpenRouter. This means users can run tests without the need for expensive API keys, making it accessible for teams of all sizes. The NDJSON event stream feature is particularly beneficial for Continuous Integration (CI) pipelines, allowing developers to integrate automated UI checks seamlessly.
The dashboard provides a user-friendly interface to monitor your tests. With a free account, users can access run history, video recordings of their test executions, and the ability to replay these runs to identify and debug flaky web flows. This replay feature is crucial for understanding where tests may have failed and for ensuring the reliability of web applications.
Additionally, BrowserBash is fully open-source under the Apache-2.0 license, allowing users to install it quickly via a single npm command. This open-source nature encourages community contributions and ensures that the tool evolves based on user feedback.
BrowserBash offers several key features that enable users to automate browser testing effortlessly. These include natural-language automation, free model options, an NDJSON event stream, a detailed dashboard with replays, and an open-source framework, making it accessible and user-friendly for developers and testers alike.
BrowserBash stands out for its natural-language automation, allowing users to write tests in simple English. For instance, a user can input "click the login button," and BrowserBash will interpret this instruction to perform the action in a browser test. This feature significantly reduces the learning curve for new users and speeds up the testing process.
The platform supports free local or cloud models through Ollama or OpenRouter, which means users can run tests without the overhead of API keys. This flexibility is particularly beneficial for small teams or individual developers looking to minimize costs while accessing powerful tools.
Another notable feature is the NDJSON event stream, which emits structured run events in a format that can be consumed directly by Continuous Integration (CI) systems and AI agents. This capability enables seamless integration into existing workflows, enhancing automation and real-time feedback.
BrowserBash also includes a dashboard with replays, where users can view their run history, access video recordings of test runs, and replay specific tests. This feature is invaluable for debugging and performance analysis, allowing teams to pinpoint issues and improve test accuracy.
Lastly, being open-source under the Apache-2.0 license means BrowserBash can be freely modified and shared, promoting collaboration and continuous improvement within the developer community. Installation is straightforward, requiring just a single npm command, making it accessible for developers of all skill levels.
BrowserBash is designed for developers, QA testers, and automation enthusiasts who want to write end-to-end browser tests in plain English, automate UI checks within CI pipelines, utilize AI agents for web tasks, and simplify debugging of flaky web flows without the need for complex selectors.
BrowserBash is particularly beneficial for professionals looking to enhance their web testing efficiency. Here are some specific use cases:
End-to-End Browser Testing: Users can write tests using plain English descriptions, making it accessible for those who may not be well-versed in programming. For instance, a user can write "User logs in and checks the dashboard" as a test case.
Automated UI Checks: Integrating BrowserBash within a Continuous Integration (CI) pipeline allows teams to run automated UI checks seamlessly. This ensures that every code change is validated against the user interface, catching issues early in the development cycle.
AI Agents for Web Tasks: Leveraging AI capabilities, BrowserBash can drive real browsers to perform routine tasks, such as filling out forms or scraping data from websites. This feature is especially useful for businesses that require data collection or testing repetitive workflows.
Recording and Replaying Runs: The ability to record and replay browser actions helps in debugging flaky web flows. By capturing the exact sequence of actions, developers can identify where things go wrong and make necessary adjustments.
No Selector Coding Required: One of the standout features of BrowserBash is its ability to automate repetitive tasks without the complexity of writing selectors. This is particularly advantageous for teams that need to quickly set up tests without extensive coding experience.
By understanding and implementing BrowserBash effectively, users can significantly streamline their testing processes, enhance collaboration, and ultimately improve their web application quality.
BrowserBash is completely free to use, providing users with a robust platform for browser testing and automation without any subscription fees or hidden costs. This makes it an ideal choice for developers and testers looking for efficient tools without financial commitment.
BrowserBash is a versatile tool designed for web developers and testers, enabling them to automate browser interactions and conduct thorough testing on various web applications. The free model allows users to take full advantage of its features without the burden of subscription fees.
For instance, a developer can use BrowserBash to run automated tests on a new web application, checking its functionality on Chrome, Firefox, and Safari without incurring any costs. This capability significantly speeds up the development cycle and improves product quality.
Common pitfalls include neglecting to test across all supported browsers or failing to write comprehensive test scripts. Leveraging BrowserBash’s capabilities effectively can improve testing accuracy and application performance.
