The bug stops here
DebugAI sits in VS Code, reads the stack trace, pulls the files that actually matter, and hands you a fix you can apply in one click. Built for the errors your copilot shrugs at.
You didn't even paste the error.
[catch]An exception fires
The extension already has the trace, your branch, and what changed since the last commit. No copying, no context-pasting ritual.
[read]It reads your codebase
Traced files come first. Then the related code your trace doesn't mention, retrieved by embeddings across the repo. The model sees what a senior teammate would open.
[explain]Root cause, plain language
If this error has hit your project before, the fix that worked leads the answer. Haiku handles the easy ones. When it's ugly, we route to Sonnet.
[apply]One click, native diff
You review it like a PR, because it is presented like one. Nothing writes to your files without your click.
Finds the null before your user does.
One command ranks the files most likely to break: what changed recently, what has broken before, what's grown too big. Each one gets read with full cross-file context. Clean files come back clean.
No findings invented to look busy. We benchmarked it on code the model has never seen and tuned until the false positives died.
You've read this stack trace before. So has it.
Every debug session leaves a signature. When the same error resurfaces, in your project or a teammate's editor, DebugAI leads with the fix that was confirmed to work. Project-scoped, never shared across accounts.
Your agent can hand us the error itself.
DebugAI ships as a standalone MCP server, and one command sets it up. It signs you in through your browser, then writes the config for every MCP client on your machine (Claude Desktop, Claude Code, Cursor, Zed, Windsurf, Cline, Gemini CLI). Each one gets adebug_error tool: the agent sends the stack trace, the same engine behind the extension sends back the root cause and ranked fixes. No key to paste. No VS Code required.

Fair questions.
Is my code sent to your servers?
Only the error message and the relevant code snippet around it. Your full codebase stays on your machine. Indexing runs locally inside VS Code.
How is this different from ChatGPT?
ChatGPT only knows what you paste. DebugAI pre-indexes your entire project: file structure, imports, call chains. It traces errors across files automatically. No architecture explanations needed.
What languages and frameworks does DebugAI support?
Python (FastAPI, Django, Flask, Streamlit, PyTorch) and JavaScript/TypeScript (React, Next.js, Express, Node.js, Vite). More added based on user feedback.
Is DebugAI actually free?
Yes. 10 debug sessions per day on the free tier, forever. No credit card required.
Will DebugAI overwrite my code without asking?
Never. Every fix shows a full diff before anything is applied. After applying you have 30 seconds to undo with a single click.
Does DebugAI work with Cursor or Windsurf?
Yes. DebugAI is a standard VS Code extension and works in any VS Code-compatible editor including Cursor and Windsurf.
Can my AI agent use DebugAI without VS Code?
Yes. Run npx -y @debugai/mcp setup. It signs you in through your browser and writes the config for every MCP client it finds: Claude Desktop, Claude Code, Cursor, Zed, Windsurf, Cline, Gemini CLI. Each one gets the debug_error tool. Nothing to paste.
How long does DebugAI setup take?
About 30 seconds. Install the extension, run "DebugAI: Sign In" from the command palette, and confirm a short code in your browser. There is no API key to find or copy. For agents outside VS Code it is one command: npx -y @debugai/mcp setup.
