CodeBurn is a local-first, cross-platform observability and cost management tool for AI coding assistants. It reads session logs from 40+ AI tools (Claude Code, Cursor, Copilot, Codex, Gemini, etc.) directly from the user's local disk, parses them, and attributes costs using a bundled pricing engine with fallbacks. The architecture is a modular monolith with a core TypeScript CLI engine and multiple platform-specific frontends (Electron desktop, Swift macOS menubar, Tauri Windows/Linux tray, VS Code extension, MCP server, and GNOME extension). The codebase demonstrates exceptional engineering discipline. It features a sophisticated versioned cache with cross-process locks and progressive hydration, a clean provider adapter pattern for ingesting heterogeneous data sources, and a robust quota monitoring system with strict error handling and credential safety. The test suite is extensive, covering parser edge cases, cache correctness, and cross-platform parity. The project is actively maintained with frequent releases and a large community (11k+ stars). The primary risk is the volatility of the external AI tool APIs it depends on for quota tracking and log formats, but the code is structured to handle this through its adapter pattern and comprehensive testing. It requires Node.js 22.13+.
Antigravity-Manager is a professional-grade desktop application (Tauri + React + Rust) that serves as an AI account manager and local proxy gateway. It manages multiple AI service accounts (Google Gemini, Anthropic Claude, OpenAI) by handling OAuth token lifecycle, device fingerprinting, quota tracking (5-hour rolling and 7-day weekly buckets), and subscription tier management (Free/Pro/Ultra). The built-in reverse proxy (Axum HTTP server) translates between different AI provider protocols (OpenAI, Anthropic, Gemini), supports streaming, handles rate limiting with adaptive retry, and provides intelligent request routing with account failover. It also syncs its configuration to popular AI CLI tools (Claude Code, OpenCode, Hermes, etc.) and includes a comprehensive monitoring dashboard, IP security filtering (CIDR blacklist/whitelist), user token management, and a warmup scheduler to prevent quota decay. The application runs as a Tauri desktop app with optional headless/Docker mode for containerized deployment.
This repository is a VS Code extension for monitoring and managing AI model quotas (Antigravity/Google Gemini/Claude/etc.). It provides a WebView dashboard and QuickPick view for real-time quota tracking, account management with OAuth authentication, auto-trigger/wakeup functionality to prevent quota exhaustion, and integration with the Cockpit Tools desktop application. The extension features quota grouping, history visualization, threshold-based notifications, multi-account support, and internationalization across 18+ languages. Architecture follows modular VS Code extension patterns with separate controllers, services, and views communicating via event-driven messaging.
