farsee

Apache-2.0 C11 RFB/VNC + RDP client that draws the remote desktop in a Kitty graphics terminal.

This is not Apple High Performance Screen Sharing (AHPSS). Classic VNC Authentication proves password knowledge only — it is not session encryption. See SECURITY.md.

nix run github:zw3rk/farsee -- --version
nix run github:zw3rk/farsee -- vnc://host.example:5900
nix run github:zw3rk/farsee -- rdp://user@host.example

Password is never taken from argv or a URL. Use the TTY prompt (echo off) or --password-fd N. Production rejects URL userinfo passwords.

Live graphics use the Kitty graphics protocol (KGP). Without a supporting terminal, use --dump-frame for a single-frame RGBA/PPM dump.

Terminals that implement KGP (per the protocol docs; feature depth varies):

Farsee is developed and manually accepted primarily against Kitty. Other entries may work for basic placement; SHM transfer, APC drain timing, and cursor overlay can differ. Nested multiplexers (tmux, screen) often need passthrough configuration.

Hermetic toolchain via the flake (flake.nix); all work goes through the Makefile (make help).

• Classic VNC (RFB 3.3/3.7/3.8): VNC Auth, Raw / CopyRect / ZRLE, Cursor, DesktopSize, input, clipboard, Bell
• Apple Screen Sharing type-33 MVP (cleartext post-auth path)
• RDP via FreeRDP
• Live graphics need a KGP-capable terminal (or --dump-frame)

No VNC TLS/VeNCrypt; type-33 ships as a cleartext MVP. Details: docs/known-limitations.md.

Apache-2.0 — see LICENSE. The RFB stack is written from public specs (RFC 6143, IANA, platform docs); it does not incorporate GPL/AGPL/LGPL VNC client sources (see ADR-0001).
