Commercial infrastructure you can run, and public .NET libraries you can take apart.
Server software with a commercial license. Client SDKs stay MIT.
MIT-licensed .NET 10 packages. Source lives in public GitHub repositories under SchipperIo.
Zero-dependency ANSI and terminal primitives: color, CP437, diffing screen buffers, ANSI/SAUCE parsing, and UTF-8 input decoding.
A tiny BCL-only IRC client: optional TLS, NICK/USER, one channel, PRIVMSG relay, and PING. Confidentiality stays with the caller.
Transport-agnostic Raft: elections, log replication, and commit/apply. You supply the transport, the log, and optionally metrics and a clock.
From-scratch SSH-2 server and client on BCL crypto: ECDH P-256, AES-256-GCM, one session channel. Transport only — no terminal library.
The row type is the schema. A Roslyn generator emits repositories: no reflection, no runtime SQL building, Native AOT clean.
Widget layer on Ansi: themed menus, line input, messages, and a multiline editor. Cells, color, and key decoding stay in the Ansi package.
Self-contained modern terminal toolkit: grid, renderer, mouse, paste, layout, and a real console host. No dependency on Ansi.
