Browsergent review
A local Chrome extension for DOM-based browser tasks, with your own compatible model API key.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Browsergent is an experimental, open-source Chrome extension for developers, power users, and small teams who want to automate browser tasks through the DOM. Users describe a goal in plain English in a side panel; an LLM generates JavaScript, and a sandboxed runtime executes typed commands on the active tab. The workflow can cover navigation, form filling, research and extraction, and QA smoke checks. Its local execution model suits people who want commands to act in their current Chrome session, including authenticated web apps, rather than automate a separate browser session.
The main distinction is its command-and-observe loop. Browsergent snapshots the active tab into structured element references, roles, and labels, then supports actions such as click, fill, select, scroll, navigation, and wait. It observes the result and errors, then can iterate or recover. Reusable skills and session-file attachments provide ways to carry repeatable instructions and context into tasks. This DOM focus is a fit for page-level work; teams looking for broader computer interaction or multi-browser coverage should look elsewhere, since Browsergent is Chrome-only and works on one active tab at a time.
Browsergent is free to download and use, and open source. There is no product subscription described in its pricing model, but users must provide an API key for an Anthropic Messages-compatible provider and pay any provider charges. Supported options include Anthropic, DeepSeek, z.ai / GLM, and compatible endpoints with a user-supplied endpoint. Installation is available through a prebuilt extension download or by building from source, with documentation as the listed support channel. Choose it if you are comfortable configuring a model endpoint and want local Chrome-tab automation; skip it if you need a supported multi-browser product or prefer a non-experimental tool with a different operating model.
