AlphaCode Browser Agent

AlphaCode Browser Agent is the Firefox execution bridge for AlphaCode, connecting an AI coding agent to real Firefox tabs, pages, browser state, and web interfaces.

Built by AliEssam, it provides a reliable browser automation layer for agentic development workflows, web development, testing, debugging, research, and browser-assisted coding.

What it does

AlphaCode Browser Agent lets AlphaCode operate Firefox through a native browser bridge and WebExtension APIs.

Browser automation
Open, close, duplicate, reload, navigate, and switch tabs
Create and manage browser windows
Go backward and forward through history
Control zoom and active browser context
Inspect active tabs and window state
Wait for navigation, page changes, and dynamic content
Web page and DOM automation
Find elements using CSS selectors and XPath
Search by visible text, labels, placeholders, ARIA roles, names, and test IDs
Inspect elements, attributes, properties, and computed state
Interact with Shadow DOM
Work with frames and iframes
Detect and operate on interactable elements
Highlight and inspect elements for debugging
Input and interaction
Click and double-click elements
Right-click and hover
Focus and blur controls
Type text into inputs
Press keys and keyboard shortcuts
Scroll pages and elements
Toggle checkboxes and radio controls
Select options from forms
Submit forms
Drag and drop where supported
Interact with dynamic single-page applications
Files, media, and browser state
Capture browser screenshots
Work with file upload workflows
Access supported download information
Inspect and manage supported cookies
Track browser sessions and tab state
Collect browser and execution telemetry needed by the agent
Agent-oriented execution

The bridge is designed for AI agents that need to inspect → reason → act → verify against a real browser.

It supports structured commands, execution status, retries, timeouts, diagnostics, native messaging, multi-tab workflows, multi-frame operations, and detailed error reporting so agent workflows can recover from common browser timing and state changes.

Designed for developers

AlphaCode Browser Agent is useful for:

AI coding agents
Browser automation
Web application testing
Front-end development
UI testing and debugging
DOM inspection
End-to-end workflows
Form automation
Browser-assisted software development
Agentic web workflows
Developer tooling
Web research workflows

It is especially useful when an AI agent needs to move beyond generating code and actually interact with a live web application in Firefox.

Works with AlphaCode

AlphaCode is a free, open-source, terminal-native AI coding agent. This Firefox extension provides the browser execution layer that allows AlphaCode workflows to interact with real web pages.

Local execution model

The extension communicates with the locally installed AlphaCode application through Firefox native messaging.

The extension does not require a hosted browser automation service. Browser operations are performed through Firefox and the local AlphaCode bridge.

Depending on the workflow, AlphaCode may request access to page content, DOM information, screenshots, browser state, cookies, downloads, or other browser data needed to perform an explicitly requested operation.

Privacy

AlphaCode Browser Agent is designed as a local execution bridge between Firefox and the AlphaCode application.

Data accessed by the extension is used to perform browser operations requested by the user or by an authorized AlphaCode workflow. Data required by those operations can be passed through Firefox native messaging to the local AlphaCode application.

The extension does not need to operate a separate hosted browser service to perform its core browser automation functions.

Because AlphaCode can connect to configurable AI providers and other tools, users should review the privacy practices and configuration of the AlphaCode installation and any external provider used by their workflows.

Open source

AlphaCode Browser Agent is part of the broader AlphaCode project ecosystem.

Important

This extension is a browser execution bridge for AlphaCode. Full agent-driven functionality requires a compatible AlphaCode installation and native messaging configuration.

Firefox browser restrictions and website security policies may prevent specific operations on certain pages or browser-managed URLs.
