Code you can read before you call us

We publish some of the tools we build. Each project below lists its license, its audience and its links, so you can check the work yourself.

PdfNetStack
Released
Create, edit, compress and sign PDF files in .NET, validate their signatures, and convert HTML and CSS to PDF. Pure C#, with no native binaries.
Optimization is lossless by default. Every optimized file is read back and proven equivalent to its source, or you get your original bytes back. On a public corpus of 77 openly licensed PDFs, the lossless profile rewrote 65 and saved 12.1%, with no failed proof. The other 12 are signed or encrypted and were left alone.
Who it is for
.NET developers who handle PDFs inside their own services, on .NET 8 and later, or on .NET Framework through .NET Standard 2.0.

Language

cypress-mcp
Released
An MCP server that lets an AI coding agent run your Cypress tests, read structured failures and rerun after a fix, without leaving the conversation.
Twelve tools cover running specs, debugging failures, discovering the suite and checking the setup. It works alongside Cypress Cloud MCP.
Who it is for
Teams using Cypress with Claude Code, Cursor, Windsurf or any other MCP-compatible agent. Node.js 22.12 or newer.
License
Apache-2.0
The repository's license since version 0.2.0. The npm package stays at 0.1.1 under BUSL-1.1 until that version is published.

We list projects we wrote ourselves, with a license and documentation you can use. Forks and old experiments stay off this page.
