Hapi is a simple, privacy-first mobile app for checking the health of your APIs directly from your device. Add your API endpoints, run quick health checks, and view response status and history without accounts, servers, or complicated setup. Everything runs locally on your phone. Hapi is designed as a lightweight companion for developers who want a fast way to check API health on the go, not a full uptime monitoring platform. What Hapi does: • Perform manual health checks against your API endpoints • View HTTP status codes and response timing • Store endpoint history locally on your device • Quickly refresh and review endpoint status • Home screen widgets for fast access (coming soon) Privacy first, by design: • No accounts or sign-ups • No proprietary backend servers • All endpoint data is stored locally on your device • Anonymous, minimal analytics and crash reporting only Your APIs stay yours. Pricing: • Hapi is free to get started. Upgrade to Hapi Unlimited with a one-time purchase to unlock: • Unlimited endpoints • Unlimited local history • Future features as they roll out No subscriptions. No recurring fees. Important notes: • Hapi does not provide uptime guarantees or alerts • Checks are run manually or on-device only • Endpoint availability depends on external systems Hapi is best used as a quick API health check tool, not mission-critical monitoring. Built for developers: Hapi is built by an indie developer who uses it daily, with a focus on speed, simplicity, and respecting your data. Have feedback or feature ideas?

Verdict

The call
