lossless-code vs lean-ctx

lossless-code: lossless-code is a DAG-based lossless context management tool for Claude Code. It preserves every message forever, cascades summaries in a directed acyclic graph, and provides full recall across sessions. It works with any LLM and has zero background processes.; lean-ctx: lean-ctx is an open-source MCP server designed to drastically reduce LLM token costs for AI coding tools like Claude Code, Cursor, and Copilot. It achieves this by transparently compressing CLI output and file context, offering up to 99% savings and making AI coding faster, cheaper, and more effective without changing workflows.
