Lilu is a statically compiled LuaJIT interpreter bundled with everything you need to build production tools on Linux — networking, crypto, filesystem, terminal UI, etc.
One binary, under 2MB, no dependencies. Core components:
Filesystem & Processes — File operations, process manipulation, pipes, forks.
Networking: TCP/UDP with TLS 1.3 support, a full HTTP(S) client, and an HTTP(S)/1.1 server. TLS is backed by WolfSSL, which is compiled into the binary.
Cryptography: hashing, HMAC, Ed25519, X.509
Terminal UI: UTF-8 aware terminal I/O, styling via TSS (Terminal Style Sheets), and a set of widgets for building CLI apps.
Extras: JSON, Markdown processing and rendering, Redis protocol support, WireGuard and ACMEv2 clients.
lilush extends lilu with a modular Linux Shell (as in Bash, Csh or Fish). Lilush Shell features:
Rich prompts: host, user, directory, git branch, Kubernetes context, Python venv.
Completions & navigation: Tab completions with scrolling, fast directory navigation and history search in the spirit of McFly and zoxide.
Built-in tools — kat (file viewer + pager), ktl for kubectl, netstat, dig, wgcli, and many more.
Extensibility — Add your own plugins. Style everything with TSS.
Lilush Shell uses Kitty's keyboard protocol and requires a compatible terminal emulator (kitty, foot, alacritty, konsole, etc.).

Projects built on the lilu runtime:
RELIW — An HTTP server & framework.
zxkitty — A ZX80 emulator for the terminal.
The project as a whole is named Lilush.
The minimal build without the shell is Lilu, the binary is lilu.
The full build with shell is Lilush Shell, the binary is lilush.
