About Marble Torch

A one-person UK software business building a small number of tools for professional .NET developers, and standing behind them.

What we make

Marble Torch builds developer tools for the .NET ecosystem. The first is ClarityTrace, a cross-platform performance profiler shaped around the way developers now work with AI coding agents. The aim is a short catalogue of tools that each do one job well, not a broad suite.

Who it's for

Experienced .NET developers who read stack traces and use agents like Claude Code, Codex and Cursor as part of their day. The tools are built to fit that workflow: readable output, sensible defaults, and nothing that needs a manual to operate.

How it's run

Marble Torch is run by one developer in the UK. That keeps the surface small on purpose: fewer products, direct support, and decisions made by the person who wrote the code.
