Pulsar: API Status Monitor

Pulsar shows the health of your APIs, databases and services on your phone. Add one authenticated GET /pulsar endpoint to your backend and Pulsar reads it with a token kept in Android's secure storage (Keystore). You see the status of every component, response times, uptime and a clear timeline of what broke and when it recovered. ALL YOUR PROJECTS AT A GLANCE • Operational, degraded or down, for every project and component • 24-hour status history and 30-day uptime • Development, Staging and Production environments KNOW WHAT BROKE, AND WHY • Plain-language errors: timeouts, TLS problems, authentication failures, closed connections • The last known state of each component when a check fails • Activity feed with incidents, recoveries and how long they lasted • Notifications when a project changes state, with per-project mute SET UP IN MINUTES • One endpoint, one token • Test Connection checks every step: server, authentication, endpoint, response and components • Setup guides for Express, NestJS, Next.js, Laravel, Django, FastAPI, Spring Boot and Go DEVELOPER TOOLS • Payload validator for /pulsar responses • Request snippets for curl, HTTPie, fetch, Python and GitHub Actions • 256-bit token generator • SLA calculator • Latency benchmark with p50, p95 and jitter • TLS inspector: issuer, expiry and days left • Incident reports in Markdown PRIVATE BY DESIGN • No account and no sign-up • No Pulsar servers: the app talks directly to your endpoints • Tokens stored in secure storage and never shown again after saving • Optional App Lock with fingerprint or face unlock • No ads, no analytics, no tracking MAKE IT YOURS • Light and dark themes • 8 languages: English, Spanish, French, German, Russian, Chinese, Arabic and Norwegian • 4 app icons Pulsar is free.
