RegPack : RegPack is a packer intended for use on minified Javascript code.
It is mostly suited to small size constraints (1kb, up to 4kb).
LeanCTX : 90% of every prompt is wasted context. LeanCTX compresses file reads, shell output, and search results — so your agent gets only what matters.
Headroom compresses everything your AI agent reads — tool outputs, logs, RAG chunks, files, and conversation history — before it reaches the LLM. Same answers, fraction of the tokens.
