context_arena
experimentalv0.1.0
Zero-copy and lock-free LLM context engine
56
ctxforge
experimentalv2.1.0
Deterministic prompt engineer for AI coding agents. Detects your project stack, attaches GitHub resources, flags missing context — never calls an LLM.

cxpak
experimentalv3.1.0
Spends CPU cycles so you don't spend tokens. The LLM gets a briefing packet instead of a flashlight in a dark room.
