Context Gateway is an open-source tool developed by Compresr, a YC-backed company specializing in LLM prompt compression and context optimization. It acts as a proxy between AI agents (like Claude Code, Cursor, OpenClaw) and LLM APIs, automatically compressing conversation history when it approaches context limits.
Key Features:
- Instant History Compaction: Compresses conversation history in the background without interrupting workflow
- Agent Integration: Supports Claude Code, Cursor, OpenClaw, and custom agent configurations
- Interactive Setup: TUI wizard for easy configuration of summarizer models, API keys, and compression thresholds
- Background Processing: Pre-computes summaries so compression happens instantly when needed
- Logging: Detailed logs in
logs/history_compaction.jsonlfor monitoring and debugging
Use Cases:
- AI-assisted coding environments where long conversations exceed context windows
- Development workflows using AI agents that need continuous context management
- Teams implementing AI tools that require efficient context optimization
- Developers building custom AI agent integrations with automatic history management
