 - [AdaL](https://sylph.ai/) — Self-evolving AI coding agent that lets models collaborate (Claude, GPT, Gemini). Runs locally, learns your codebase patterns.
 - [Tokscale](https://github.com/junhoyeo/tokscale) — CLI tool for tracking token usage from AI coding agents (OpenCode, Claude Code, OpenClaw, Codex, Gemini CLI, Cursor IDE, AmpCode, Factory Droid) with a global leaderboard and 2D/3D contribution graphs.
 - [BurnRate](https://getburnrate.io) - Local-first AI coding cost analytics. Tracks Claude Code, Cursor, Codex, Copilot, Windsurf, Cline, and Aider. Cost breakdowns, 23 optimization rules, rate limit monitoring, provider comparison, and PDF reports.
+- [onWatch](https://github.com/onllm-dev/onwatch) — Open-source Go CLI that tracks AI API quota usage across 7 providers (Anthropic, OpenAI Codex, GitHub Copilot, Synthetic, Z.ai, MiniMax, Antigravity). Background daemon with Material Design 3 web dashboard, ~15MB binary, <50MB RAM, zero telemetry.
 - [Caliber](https://github.com/rely-ai-org/caliber) — Open-source CLI that scans your codebase and generates AI agent configs (CLAUDE.md, .cursorrules, skills, MCPs) for Claude Code, Cursor, and Codex. Scores your setup 0–100 and recommends MCP servers.
 - [vsync](https://github.com/nicepkg/vsync) — CLI tool that syncs Skills, MCP servers, Agents & Commands across Claude Code, Cursor, OpenCode, and Codex with automatic format conversion (JSON ↔ TOML ↔ JSONC).
 - [rule-porter](https://github.com/nedcodes-ok/rule-porter) — Zero-dependency CLI that converts AI IDE rule files between Cursor (.mdc), CLAUDE.md, AGENTS.md, Copilot, and Windsurf. Bidirectional with lossy-conversion warnings.
