Open Source C AI Coding Tools

codebase-memory-mcp is a high-performance code intelligence MCP server built for AI coding agents. It indexes codebases into a persistent knowledge graph so agents can understand architecture, symbols, call chains, routes, and cross-service relationships without reading every file repeatedly. The project uses tree-sitter AST analysis across 158 languages and adds Hybrid LSP type resolution for major languages like Python, TypeScript, JavaScript, Go, C#, Java, Rust, C, and C++. It is built for speed, with average repositories indexed in milliseconds and structural queries answered in under one millisecond. It ships as a single static binary for macOS, Linux, and Windows with no shared library dependencies. It also includes semantic search, BM25 search, graph visualization, auto-indexing, and cross-repository intelligence.

Clawdmeter is an ESP32-based desk dashboard for monitoring Claude Code usage. It runs on supported Waveshare touch AMOLED ESP32 boards and pairs with a laptop over Bluetooth. The device displays usage information while also showing playful pixel-art Clawd animations that become busier as usage rate increases. It includes a companion macOS daemon that reads Claude credentials from the local Keychain, polls usage data, and sends updates to the display over BLE. The board’s side buttons can also send keyboard shortcuts for Claude Code voice mode and mode toggling through BLE HID. Clawdmeter is best suited for Claude Code power users who want a physical, ambient view of their AI tool consumption.
