KDB - The Kindly Debugger

Give your AI the superpower of time-travel debugging.

Rewind execution, find what went wrong, fix the bug timeline.

What is KDB?

KDB is a time-travel debugger that connects to Claude, Cursor, or any MCP-compatible AI assistant. Instead of reading code and guessing, your AI can now:

• Attach to running processes
• Set breakpoints and catch crashes in action
• Step forward through execution
• Step BACKWARD through time to find the root cause
• Inspect memory and variables at any point in history

All through natural language. Just ask Claude to debug your code.
