Observability & Evals tools for Cursor

macOS menu bar app showing usage stats for Codex, Claude, Cursor, Gemini without login. On-device parsing

Free, local tool that tracks AI coding token usage and cost across 31 tools and agents by model, project, and task. Worth including because cross-tool cost visibility is the missing prerequisite for agent FinOps in multi-tool teams — most observability tools either require cloud upload or only cover a single provider

by Ruller_Lulu - A desktop pet that reacts to your Claude Code sessions in real-time — thinking, typing, juggling, sleeping, and more. Yep. It's undeniably endearing. And at the end of the day, isn't that what Claude Code is all about?

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

(4.4k ⭐) - macOS menu bar app for tracking Claude, Codex, and other AI coding subscriptions, with usage limits, reset times, credits, and spend

(3,267 ⭐) - Desktop widget for tracking token usage, costs, limits, and session activity across Claude Code and other coding tools, with multi-device synchronization

(3,303 ⭐) - Local proxy and trace viewer for inspecting coding-agent API requests, prompts, tool calls, streaming responses, and token usage

(2,960 ⭐) - Desktop app that displays coding-assistant usage limits, reset times, and session status in a screen-edge notch, with macOS and Windows versions

Evaluates coding-agent workflows across five dimensions and turns project and session evidence into prioritized, evidence-bounded findings with scoped repair actions. Runs inside Claude Code, Codex, Cursor, GitHub Copilot, and other hosts, making it a practical cross-tool diagnostic layer for improving the harness rather than just reviewing the final diff

(454 ⭐) - Local observability map for Claude Code, Codex, and Cursor that tracks plans, tool calls, file changes, and progress in real time

Open-source Go CLI that tracks AI API quota usage across 7 providers (Anthropic, OpenAI, GitHub Copilot, MiniMax, and more). Works with Claude Code, Codex CLI, Cursor, Cline, and other vibe coding tools. Background daemon, <50MB RAM, zero telemetry

by mick - A tiny, hook-driven macOS menu-bar indicator of Claude Code's live turn status — an animated icon while thinking or running a tool, a dot when awaiting permission, and an elapsed-turn timer — aggregated across concurrent CLI, Claude Desktop, and Cursor sessions. Stateless AppKit/Swift app that self-launches on session start and quits when idle

(537 ⭐) - Analytics dashboard for AI coding agents including Claude Code, Cursor, Windsurf, VS Code Copilot, Zed, Antigravity, OpenCode, and Command Code

Self-hosted, local-first observability and kill switch for coding agents, reading Gemini CLI sessions alongside Claude Code, Codex, Cursor, OpenClaw, Aider, Goose, and others. Reads the session logs the runtimes already write on disk, so there is no SDK and nothing in the request path. Shows sessions, transcripts, tool calls, tokens, and cache-aware cost per session and model; an opt-in emergency

Wireshark for MCP: a transparent proxy that shows every JSON-RPC frame between your real client and MCP servers, live in your terminal. Worth including because MCP Inspector tests servers from its own client, so it can't see the calls your actual agent makes, misses, or hangs on — mcpsnoop sits in the real data path and makes those failures visible

Open-source AI test agent CLI by TestMu AI that turns requirements into end-to-end tests and runs them on desktop web, Android and iOS, with every test linked to the acceptance criteria it covers

by minchenlee - A macOS menu-bar app (and companion JSON CLI, built from one Rust/Tauri binary) that auto-discovers running Claude Code sessions by scanning OS processes and shows live working / needs-attention / idle status, plus session-history search, cost tracking, and PM-style worker orchestration. Rust + Tauri 2 + Svelte 5, with a token-gated mobile web client

Local-first CLI and dashboard for analyzing AI coding sessions from Claude Code, Cursor, Codex CLI, Copilot CLI, and VS Code Copilot Chat. SQLite-backed with terminal analytics, browser dashboard, and LLM-powered insights

Tool-agnostic AGENTS.md authoring kit (MIT) with 15 stack-specific templates, a tool compatibility matrix, an npm CLI + GitHub Action linter (agents-md-lint), and a migrator (agents-md-migrate) that converts .cursorrules, CLAUDE.md, Copilot, Windsurf, Cline, and Aider configs to AGENTS.md. Works across Cursor, Claude Code, Copilot, and 30+ AI coding tools. Free and open source

External: Universal MCP gateway federating 430+ tools from 37 servers through one endpoint. 75% RAM reduction

Always-on security guardrails for AI-generated code

Plan-before-code behavior modifier for agents
