Trace

Browser-native AI coding agent. Build apps and debug live web apps directly from your browser.

Trace – Browser-Native AI Coding Agent Trace is a browser-native AI coding agent that helps you build, edit, debug, and ship web applications without leaving your browser. Unlike traditional AI coding tools that mainly understand your source code, Trace understands both your project and your live application. It connects to your local development environment, interacts with your running app, and helps you write, modify, test, and debug code from a single workspace. Build. Debug. Design. Whether you're starting a new project or working on an existing codebase, Trace helps you: 1. Build full-stack applications using natural language 2. Create and edit React, Next.js, Node.js, and modern web applications 3. Understand and navigate large codebases 4. Refactor, generate, and modify production-ready code 5. Design and edit UI directly from your browser 6. Debug live applications by inspecting the DOM, network, console, storage, and runtime state with direct CDP access. 7. Identify root causes and apply fixes 8.Test changes and iterate without constantly switching between your browser, IDE, DevTools, terminal, and AI chat Why Trace? Modern development is fragmented across browsers, IDEs, terminals, documentation, and AI assistants. Every context switch slows you down. Trace brings your development workflow into one place. It combines AI-powered coding, live runtime awareness, browser inspection, and project context so you can build and troubleshoot software where it actually runs. Whether you're building a new feature, exploring a large codebase, fixing a production issue, or polishing your UI, Trace helps you move from idea to working software faster. Permissions Trace requests only the permissions required to perform the actions you ask it to do. Debugger — Inspect and debug live web applications. Host permissions — Access the web pages you choose so Trace can inspect, edit, and debug them. Native Messaging — Securely connect to the local Trace Agent to access your project files and execute development tasks. Storage — Save your preferences, conversations, and extension settings. Trace never monitors your browsing activity unless you explicitly use it on a page. Privacy Trace only accesses browser data and local project information needed to perform the actions you request. Your browsing activity and project files are never accessed unless you choose to connect your project or use Trace on a page.
