Systems software, built from scratch.

We build foundational infrastructure you can own outright — compiled, inspectable, self-hostable, and honest about what it does and does not do.

pcc, our compiler toolchain, is open source and available today.

Products

pcc

Compiler toolchain

A Python-authored compiler toolchain. Its most mature path is a C frontend that lowers C to LLVM IR and runs real third-party projects — Lua, SQLite, PostgreSQL libpq, zlib, PCRE, OpenSSL and nginx among them. It self-hosts through a three-stage bootstrap with no libpython, ships five comparative GC backends selectable at startup, and includes an in-tree native backend that emits code without LLVM.

A research compiler with practical integration tests — not a drop-in replacement for Clang or CPython.

Built on pcc

pcc-gui

A declarative desktop GUI framework written in pcc-Python and compiled to native code by pcc: a retained element tree, a bounded style grammar, layout, theme animation, CoreGraphics/Metal drawing and an AppKit window bridge — with no libpython at run time. Currently macOS on Apple silicon.

GitHub

pcc-gateway

A virtual-thread gateway built on the pcc runtime — HTTP/1.1 server, reverse proxy, DNS and TLS provider. Recently extracted from the compiler core and still moving; build it against an installed pcc.
