Why choose Osminog?

Most monitoring tools charge extra for load testing, status pages, and fast check intervals. Osminog combines everything in one platform — no hidden fees, no feature walls.

1-Second Check Intervals

Most services limit free checks to 5-minute intervals. Osminog supports intervals down to 1 second — catch issues in real time, not minutes later.

Multi-Channel Alerts

Email, Telegram, and in-app notifications — all included. Configurable thresholds with EMA-based spike detection and cooldown to avoid alert fatigue. No per-channel upsell.

Real-Time Live Charts

WebSocket-powered live charts with zoom, pan, and separate error lines (4xx/5xx). Most services show delayed data — Osminog streams results as they happen.

Built-In Load Testing

Up to 100 concurrent requests per tick in burst or distributed mode. Other services charge separately for load testing — here it's part of every plan.

Hosted Status Pages

Public status pages with auto-incidents, subscriber notifications, and embeddable widget — included. Standalone status page services charge $29+/mo separately.

WAF & Auth Bypass

Custom User-Agent, Referer, and multi-header auth let you monitor endpoints behind Cloudflare, AWS WAF, or any firewall. Most free monitoring services can't do this.

SSL Certificate Monitoring

Automatic daily SSL certificate checks for all HTTPS projects. Get notified 7, 3, and 1 day before expiry — never let an expired cert take your site down.

Monitoring chart example

Burst pattern

All concurrent requests are fired simultaneously at each tick. Ideal for stress testing and peak load simulation — see how your server handles sudden spikes of traffic all at once.

Realistic user distribution

Requests are spread evenly across the check interval, simulating real user behavior. Perfect for monitoring actual production performance without artificial load spikes.

Monitor like a real user

Strict firewalls and WAFs block bots. Osminog lets you pass through by looking like a real visitor.

Custom User-Agent

Set any User-Agent header to mimic real browsers like Chrome, Firefox, or mobile Safari. Avoid being blocked by WAFs that reject unknown or missing user agents.

Custom Referer

Send a Referer header with each request to simulate traffic coming from a specific page. Essential for testing hotlink protection, referrer-based access rules, or analytics accuracy.

Pass through WAFs

Combine custom headers with authentication (Basic, Bearer, or custom) to monitor endpoints protected by Cloudflare, AWS WAF, or any strict firewall — just like your real users access them.

About Osminog Monitoring Service

Osminog is a comprehensive website monitoring platform designed for developers, system administrators, and businesses that depend on their online presence. Just like its namesake — the octopus — Osminog extends its reach to watch over all your web properties simultaneously, providing real-time visibility into uptime, performance, and availability.

Whether you run a single blog or manage dozens of production services, Osminog scales to your needs. Our monitoring engine performs HTTP checks at configurable intervals from 1 second to 1 hour, records response times, and detects downtime within seconds. When a problem is detected, you receive instant notifications via email, Telegram, or the web dashboard so you can respond quickly and minimize impact on your users.

Beyond monitoring, Osminog offers hosted status pages that automatically reflect your service health. Components linked to monitoring tasks update in real time, incidents are created and resolved automatically, and your customers can subscribe for email notifications. Embed a status widget on your own site or share a public URL — all included in Pro and Business plans.

Osminog offers a generous free tier, making professional-grade monitoring accessible to everyone. For teams and businesses with higher demands, our Pro and Business plans provide extended website limits, background monitoring, load testing, status pages, and longer data retention. Explore our pricing to find the plan that fits your needs.
