Headroom is a context optimization tool that dramatically reduces LLM API costs (50-90%) by intelligently compressing context windows. It identifies and removes redundant information, compresses long documents into essential summaries, and optimizes the prompt-to-context ratio. Particularly effective for RAG pipelines where retrieved context often contains significant redundancy. Part of the awesome-llm-apps collection.
