Hi, I'm Sven.
I make tools that simplify my daily work. I automate annoying tasks. I write low-level code and debug it.
Windows internals, debuggers, and the tooling around AI-assisted engineering. What I learn ends up written up here and shipped on GitHub.
Tools for people who debug for a living.
Debuggers, protocol servers and native tooling. Open source where it can be, commercial where it has to be.
- open source mcp-windbg
Crash-dump analysis, driven by AI. An MCP server that lets Claude, Copilot or any MCP client drive WinDbg: dumps, live sessions and the Windows kernel.
- open source dap-dbgeng
Native Windows debugging for VS Code. A Debug Adapter Protocol server on the same engine as WinDbg: C and C++, services, and kernel-mode.
- company Liasoft
Native developer software for low-level engineers: C++ code coverage and compile-time C++ obfuscation, built and sold by my company.

Release notes, debugging stories and the occasional opinion on working with AI.
All posts- 🚀 New Release: mcp-windbg 1.1.0
Support for the 2.x MCP SDK, a new wait_for_break tool, and fixes for 'g' freezing the machine it was supposed to release.
- 🚀 New Release: mcp-windbg 1.0.0
Kernel debugging, session IDs, and a redesigned tool surface. The first stable release.
- 🚀 New Release: mcp-windbg 0.15.0
Break into live sessions, redact sensitive output before it reaches the model, and a brand-new documentation site. A year and a month in, with 1.4k stars and a community that keeps showing up.
- Introducing Native Windows Debugging for VS Code: Kernel & Remote Debugging
Last time I had a proof of concept. This time I closed the gap: remote debugging and Windows kernel debugging, straight from VS Code, powered by the same engine as WinDbg. It's open source and on the Marketplace.
- The Joy of Writing a Debugger Adapter for Visual Studio Code
I only wanted a faster remote debugging workflow for a service running in a VM. Instead, I ended up learning DAP, wrapping WinDbg, and building a working first proof of concept debugger adapter for VS Code.
- Meet Ralph: The AI Coding Agent That Just Keeps Going
I built an autonomous AI agent that works from a PRD, verifies its own work, and ships code while I sleep. Here's Ralph.
