API Monitor — Uptime & Latency

API Monitor is a lightweight uptime and health dashboard for any HTTP endpoint you depend on — public APIs, internal services, status pages, and webhooks. KEY FEATURES • Per-API check intervals, timeouts, and HTTP method. • User-defined classification: choose how each HTTP range (1xx–5xx) maps to Online, Warning, or Down. • Response body rules: trigger Down/Warning when the body contains, equals, or matches a regex — perfect for status JSON like {"status":"ok"}. • Response time thresholds for Warning and Down. • Headers, Bearer / Basic / API Key / Custom authentication, optional JSON body. • Background monitoring with WorkManager. Battery-friendly. • Notifications when an API changes state or goes down. • Pre-loaded examples for GitHub, Stripe, Slack, OpenAI, Cloudflare, Google, Discord, Twilio, AWS, and npm — ready to monitor out of the box. • Material You design with dynamic color, light/dark themes. • Available in English, Français, Español, and 中文. • Local-only data. Nothing is sent anywhere except to the endpoints you add. WHO IT IS FOR • Developers who want a quick health check on the APIs they ship and depend on. • Operators on call who need a glanceable status board on their phone. • Anyone curious about whether their favorite service is up. PRIVACY API Monitor does not collect personal data. The only network requests it makes are to the URLs you configure, on the schedule you set. Configuration is stored locally on your device and is excluded from cloud backups.
