PeekAPI

PeekAPI is a server-side middleware that gives you a real-time analytics dashboard for your API. Add one line of code to your API server and get instant visibility into request volume, error rates, latency, and who's consuming your endpoints. SDKs available for Node.js, Python, Go, Rust, Ruby, PHP, and Java — covering 18+ frameworks including Express, FastAPI, Gin, Actix Web, Rails, Laravel, and Spring Boot. Every SDK is zero-dependency. Features: live request stream, per-endpoint analytics, automatic consumer identification (privacy-safe via SHA-256 hashing), and configurable alerts via email, Slack, Discord, Telegram, or webhook. Free tier: 500K events/month.
