Website monitoring, API monitoring,
server monitoring & more.
Free uptime monitoring for websites, APIs, servers, and ports — plus Sitemap Link monitoring, AI token tracking, cloud cost alerts, platform health checks for 24 self-hosted applications, and 17 notification channels. One fully hosted dashboard.
Uptime Monitoring
HTTP & HTTPS — Website & API Monitoring
The core of website monitoring and API monitoring. MonitorGiant checks any URL for the expected status code — websites, REST APIs, health-check endpoints, webhooks, and payment gateways. Free plan uses HEAD; GET and POST with custom headers on paid plans.
Keyword Detection
Goes one layer deeper than standard website monitoring. Fetches the full response body and searches for the presence or absence of any text string — catch silent failures that return 200 OK but serve error content. Free plan uses GET.
Ping / Reachability — Server Monitoring
Server monitoring at the network layer — verifies a host is reachable via TCP connection. Works on all cloud environments including those that block ICMP. A host is confirmed alive if the connection is accepted or refused.
Port Monitoring — Deep Server Monitoring
Server monitoring at the service level — confirms TCP services are accepting connections on any port. Catch a crashed database or mail server that a simple ping won't detect. Any port, any TCP service.
SSL Certificate Expiry
Know when your certificates expire before your users do. Configurable alert window. Flags immediately if already expired. Available on paid plans.
Journey Monitor — Multi-Step Flows
Walk through a sequence of HTTP requests exactly as a real user would. Each step has its own URL, status code, and optional keyword check. MonitorGiant stops at the first failing step and tells you exactly which one broke — not just "site is down." Templates for e-commerce checkout, SaaS sign-up, and API sequences. Available on paid plans.
Sitemap Link Monitor — Broken Link Detection
Reads your sitemap.xml and checks every listed URL on a schedule using lightweight HEAD requests. Broken links (4xx/5xx), redirect chains, and slow pages are grouped into one consolidated alert per scan — not one notification per URL. Includes scan diff to detect added or removed URLs. Available on paid plans.
Flexible Check Intervals
5-minute checks included on the free plan. Paid plans unlock intervals down to 30 seconds — per monitor, per need.
Alerting
Instant Downtime Alerts
The core of downtime monitoring — down and recovery emails sent the moment a status changes, with full context: error message, duration, and a direct link to the monitor. Downtime monitoring that actually wakes you up first.
Notification Profiles
Route alerts to specific people per monitor. On-Call Engineers, DevOps Team, Client Contacts — configure who gets notified for each service.
Incident History
Full audit trail of every outage — open time, close time, duration, and all alert events. Open incidents are visually distinguished from resolved ones.
Pause & Resume
Pause any monitor during planned maintenance windows. Resume with one click. No alert noise, no false incidents in your history.
Analytics & Reporting
30-Day Uptime Percentage
Rolling uptime percentage computed from all check results. Colour-coded at a glance: green ≥ 99%, amber ≥ 95%, red < 95%.
Response Time Tracking
Every check records response time in milliseconds. View trends in an interactive chart per monitor — spot performance degradation before it becomes downtime.
Infrastructure
Multi-Region Checks
Checks run from multiple geographic regions simultaneously. A monitor is only marked DOWN when all regions agree — eliminating false positives from regional network blips.
Fully Hosted
MonitorGiant is a fully managed SaaS platform. No servers to provision, no databases to manage, no workers to deploy. Sign up and start monitoring immediately.
Team & Access
Multi-Organisation
One account can manage multiple independent organisations. Each org has its own monitors, members, projects, and notification profiles. Ideal for agencies managing client accounts.
Role-Based Access
Org Admin and Org Member roles with fine-grained control. Members can belong to multiple organisations with different roles in each.
Email Invite System
Invite team members by email. Secure token-based links with 7-day expiry. Multiple team seats available on paid plans.
Google OAuth
One-click login with Google. Account auto-links to an existing email address if present. Fast, secure, no password to manage.
Projects
Organise monitors into named projects for logical grouping. Filter your dashboard by project. Helps agencies separate monitors by client.
AI & Cloud Monitoring
AI Token Burn Monitor
Track OpenAI, Anthropic, and Gemini usage in real time. Alert when spend spikes above your 15-day rolling average.
AI Circuit Breaker
Configure a webhook or email action that fires automatically on abnormal AI usage. Your systems get the signal instantly.
AI Quality Monitor
Send golden prompts to your AI service on a schedule. Detect response quality degradation using semantic similarity before users notice.
MCP Health Monitor
3-layer protocol check for MCP servers — reachability, initialize, and tool availability. Know your AI agent infrastructure is fully operational.
Revenue Loss Tracker
Correlate downtime events with estimated revenue impact. Quantify the business cost of every outage for reporting and prioritisation.
AI Status Feed
Live status of OpenAI, Anthropic, Google AI, Cloudflare AI, Hugging Face, and more — surfaced in your dashboard. Free for all users.
Cloud Cost — AWS
Daily spend baseline, rolling average, and spike detection for your AWS account. Get alerted before costs run away.
Cloud Cost — GCP
Track Google Cloud spend and surface anomalies in your MonitorGiant dashboard alongside your uptime monitors.
Cloud Cost — Azure
Monitor Microsoft Azure consumption daily. Alert when spending deviates from your established baseline.
Platform Health Monitoring
Beyond HTTP 200 — MonitorGiant connects to each platform's built-in API and checks database health, cron jobs, checkout function, queue depth, and plugin status. No plugin to install. Connect with a read-only API token.

How MonitorGiant compares
Surface monitoring checks if your server responds. Deep Monitoring checks if your application actually works.
