Website and API Endpoint Monitoring
Every 60 Seconds
Uptimes pings your website and API endpoints directly from your browser every 60 seconds. Track uptime, response time, status changes, and heartbeat history without Docker, hosting, or a separate monitoring server.
Try Website Uptime Monitoring Right Now
Add multiple domains below and watch Uptimes ping website and API endpoints entirely within your browser. Monitors stack under each other just like the real extension.
Endpoint Monitoring Features
Without Server Overhead
Designed for developers and site owners who need website uptime monitoring, API response time tracking, and simple endpoint health checks without extra infrastructure.
Browser-Based Endpoint Monitoring
Runs entirely inside your browser tab. No accounts, no installs, no server setup. Add a URL and start checking endpoint availability immediately.
60-Second Endpoint Checks
Automatic website and API pings every 60 seconds. Each check logs response time and HTTP status to give you a clear endpoint history view.
API Response Time Graphs
Visualise website and API latency trends with line charts. Instantly spot slow endpoints, response time spikes, and availability anomalies over time.
Website Uptime Statistics
Current response, average response, uptime percentage, endpoint status, and last-checked timestamp all stay visible at a glance.
Private Monitoring Data
Your monitored URLs never leave your device except for the endpoint checks you request. Monitoring history stays in browser storage with zero telemetry.
Unlimited Website and API Monitors
Add as many endpoints as you need. Production websites, APIs, staging URLs, landing pages, and dashboards can all be monitored simultaneously.
Start Endpoint Monitoring in 30 Seconds
Install the Monitoring Extension
Add Uptimes to your browser from the Chrome Web Store. One click, no sign-up required, and no monitoring server to maintain.
Add a Website or API Monitor
Click "+ Add Monitor", paste your endpoint URL, and save it. Uptimes can monitor websites, APIs, staging URLs, and public service endpoints.
Watch Endpoint Health Live
Uptimes begins pinging immediately. See live response times, heartbeat bars, endpoint status, and uptime statistics update in real time.
Monitor Websites, APIs, and Public Endpoints
Uptimes is built for lightweight endpoint monitoring when you want a fast answer to one question: is this URL healthy right now?
Website Uptime Monitoring
Use Uptimes to check personal sites, client websites, landing pages, documentation portals, and dashboards. Each monitor runs a 60-second heartbeat so you can see whether the page is responding and how long the response takes.
API Endpoint Monitoring
Track public API endpoints, health check routes, webhook receivers, and staging services. Uptimes records response time history and uptime percentage so slowdowns are easier to spot before users report them.
Browser-Native Monitoring
Because Uptimes runs in the browser, setup is simple. There is no VPS, Docker container, hosted worker, or external monitoring backend to configure. Your monitor list and recent uptime history stay local to your browser.
