API Pulse: Uptime Monitor

Monitor your APIs, microservices, and websites directly from your phone — 100% offline, privacy-first, and zero cloud dependency. API Pulse is a developer-focused HTTP monitoring tool designed for solo creators, backend engineers, and QA testers. Track uptime, measure response latency, assert payload content, and receive instant notifications when your endpoints fail. ⚡ KEY FEATURES • Comprehensive HTTP Method Support: Monitor GET, POST, PUT, PATCH, DELETE, HEAD, and OPTIONS requests with custom headers, query parameters, request bodies, and configurable timeouts. • Smart Assertions: Go beyond simple status codes. Assert expected HTTP response codes (or any 2xx), enforce maximum acceptable latency, and validate response body content (string contains matching). • One-Tap cURL Import: Paste any cURL command straight from Postman, browser dev tools, or terminal. API Pulse automatically extracts the URL, method, headers, and request payload seamlessly. • Background Checks & Instant Alerts: Reliable background monitoring scheduled around the clock. Receive high-priority notifications after consecutive failures (configurable threshold) and instant alerts when your service recovers. • Interactive Latency Charts: Visualize endpoint performance with clean latency trends. Track Min, Average, and Max response times, latency threshold markers, and failure spikes across customizable time ranges. • Detailed Log History & Header Inspection: Review paginated check history, filter by failures only, and inspect captured HTTP response headers with a single tap to copy. • Data Ownership & Privacy: No account creation, no external servers, no telemetry. All your endpoint configurations, auth tokens, and response histories remain securely on your local device. Export your logs anytime as CSV or JSON. --- 💼 FREE vs PRO (LIFETIME) Free Tier: • Up to 3 active endpoints (expandable with rewarded bonus slots) • Standard check intervals (15 minutes and above) • 3-day log history retention Pro Tier (One-time Lifetime Purchase): • Unlimited endpoints • Fast monitoring (down to 1-minute intervals) • Unlimited log history retention • Completely ad-free experience Built by developers, for developers.
