DeepSleep-beta vs lean-ctx

DeepSleep-beta: DeepSleep is a local-first AI coding memory that watches your files while you work, generates summaries when idle, and answers 'what was I working on?' instantly. It works with Ollama, VS Code, Cursor, Windsurf, Claude Desktop, and MCP, with cross-project search via Neural Link. Completely free, no cloud, no API key.; 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.
