A from-scratch Brotli codec in pure Common Lisp (no FFI) — full RFC 7932 decompressor + entropy-coding compressor.

a common lisp bitcoin node

A from-scratch Tor client in Common Lisp — ntor circuits, directory validation, SOCKS5, and a v3 onion-service client. Clean-room, no C-tor/Arti.

Uniform outbound transport for Common Lisp: dial direct / SOCKS5 / pluggable backends (Tor via cl-tor-transport).

bare metal lisp for sovereign computing in the infinite zero-day future

Pure-CL copy-on-write B+tree key/value store (no FFI/mmap, crash-safe). Research/educational — not audited.

First-class text rendering in pure Common Lisp — sfnt/WOFF2, CFF, variable fonts, OpenType shaping, analytic gamma-correct rasterizer. No FFI.

A clean-room TLS 1.3 + 1.2 client in pure Common Lisp — AES-GCM, ChaCha20-Poly1305, X25519, RSA/ECDSA/Ed25519 certificate validation, handshake + record layer over a pluggable transport. No OpenSSL, no FFI.

Dependency-free SBCL secp256k1 / ECDSA / BIP340 Schnorr (own SHA-256/HMAC). Research/educational — not audited; not constant-time.

A Lisp-native JavaScript engine — clean-room, no FFI. source → bytecode → stack VM; 88% test262.

A from-scratch web rendering engine in pure Common Lisp — HTML/CSS parsing, cascade, layout and a truecolor rasterizer. Acid2 pixel-perfect, Acid3 100/100. No FFI.

A from-scratch Zstandard codec in pure Common Lisp — no FFI, no libzstd. Reads .zst frames (raw/RLE/compressed, Huffman + FSE, LZ77, XXH64) and writes valid zstd; differential-tested byte-for-byte against libzstd.
