🚀 Building the High-Performance .NET Browser Ecosystem

I’m Todd (LostBeard), an independent developer with 40+ years of experience—from BASIC on a Commodore 64 to modern GPGPU kernels. I build the foundational infrastructure for .NET in the browser that doesn't exist anywhere else.

Stats that matter (May 2026):

  • 364,570 Total NuGet downloads across the SpawnDev ecosystem.
  • 4,689+ GitHub contributions in 2026 — maintaining a high-velocity, production-grade release cycle independently.
  • 54 Packages live on NuGet, providing critical infrastructure for the .NET community.
  • 100% Free & MIT Licensed. No middleman, no overhead.

I don't just write wrappers; I'm building an ecosystem where "GPU-stay-GPU" is the law and high-performance C# runs everywhere.

🛠️ The SpawnDev Stack

I build the tools the .NET community depends on to push the limits of WebAssembly:

🤖 How I Work: The AI Crew

I operate a high-velocity "AI crew"—a team of custom coding agents coordinating via a file-based protocol I designed. This allows me to maintain dozens of complex libraries with the output of a full engineering team.

The Challenge: Running this "crew" and the high-performance hardware (RTX 40-series/Apple Silicon) required for GPGPU testing carries significant overhead. I currently fund 100% of these compute costs out of pocket.

💡 Why Sponsor?

When you sponsor me, you are funding the R&D of .NET infrastructure that billion-dollar companies won't build.

  • For Individuals: If my tools saved you weeks of debugging or writing interop, consider a donation to keep the "crew" running.
  • For Companies: Ensure the libraries powering your production apps remain stable, optimized for .NET 10, and ready for the WebGPU revolution.

Current Goal: Funding a dedicated AI maintenance rig to automate 24/7 regression testing across all 6 ILGPU backends to ensure every release is "final".

"Every release is the FINAL release. No 'fix it later.' Library bugs are HIGHEST PRIORITY. Fix it at the source." — My development philosophy.

Thank you for supporting independent, open-source infrastructure.
