Ctxfy is a Context State Engine that compresses LLM conversation history by up to 95%. It strips chit-chat and redundancy, preserving only "Hard State" β decisions, constraints β into a portable State Object and Artifacts - code, schemas, etc. Drop it into any model as a system prompt, inject it into agent loops, or fast-forward it with new diffs and logs. REST API, model-agnostic, zero-retention mode available.
