Prove it's up
If it isn't monitored, it doesn't exist.
Quismon is synthetic monitoring from 33 regions with instant alerts. From $5/mo, and the free tier is permanent.
Start with the web UI, API or MCP. Switch to Terraform whenever you want.
Point a coding agent at the API or MCP and monitoring runs in a minute. When you're ready for infrastructure-as-code, the API exports your checks as pre-formatted Terraform - nothing to re-create, everything carries over.
Step 1 - start anywhere
Web UI, one curl, or your coding agent via the API or MCP. Point the agent at quismon.com/llms.txt and say: "read quismon.com/llms.txt, then set up monitoring for our production site and APIs and alert me by email" - that prompt is enough.
Step 2 - iterate with the agent
Add checks, wire alerts, read incidents - all through the same API, Terraform or MCP surface.
Step 3 - formalize when ready
The API exports everything as pre-formatted HCL:
https://api.quismon.com/v1/exports/terraform > monitors.tf

Everything you need to monitor
From simple HTTP checks to complex multi-step transactions, Quismon has you covered.
Multi-Region Checks
Run checks from 33 locations across 6 continents. You'll know immediately if a problem is affecting everyone or just users in a specific region like Tokyo or São Paulo - and when a check fails, it's correlated against active incidents from AWS, GCP, Cloudflare, Fastly and more, matched by where the failing endpoint is hosted. Cloud outage or your outage: you'll know.
14 Check Types
HTTP/HTTPS, HTTP/3, Ping, TCP, UDP, DNS, DNSSEC, SSL, Multistep, Throughput, SMTP/IMAP, Traceroute, and real-browser Playwright checks. All configurable via API or console.
Instant Alerts
Send alerts to Email, Slack, ntfy.sh, or your own webhook endpoints. You'll know the moment something breaks, not hours later when customers start complaining.
Public Status Pages
Publish a branded status page on your own domain with live uptime, response times, and incident history. See a live example.
API-First
A complete REST API with OpenAPI documentation. Everything you can do in the console, you can automate. Integrates with your existing CI/CD pipelines and monitoring workflows.
Multi-Step Checks
Build complex workflows with many sequential steps. Each step has its own timeout, and you get per-step response times. Know exactly which API endpoint is slow. Perfect for login flows, API chains, and user journeys.
Terraform Provider
Define your monitoring checks right alongside your infrastructure code. Version control your monitoring, deploy checks via CI/CD, and roll back changes if something breaks.
Inverted Checks
Alert when something shouldn't be reachable. Verify your firewall actually blocks that database port, confirm private services stay private, and catch misconfigurations the moment they expose your infrastructure.
Check Types
Comprehensive monitoring for every public-facing aspect of your stack - 14 base types, multiplied by modifiers that make each one smarter: inverted (assert the bad state is absent), starts-broken (test-driven, with fix-by deadlines), and expiring (temporary, auto-deleting checks for CI/CD and incidents).

Why external monitoring?
Your monitoring should be independent of your infrastructure.
Independent of Your Cloud
When AWS or Azure has an outage, their internal monitoring tools often go down with them. Quismon keeps running because we're separate from your infrastructure.
True Global Perspective
Your users are everywhere. Quismon checks your service from 33 locations worldwide, so you'll see performance issues that only affect users in specific regions.
Third-Party Verification
Independent uptime data for SLA compliance, customer trust, and incident post-mortems. Prove your uptime to stakeholders with objective data.
Built on Vultr
We run on Vultr's global infrastructure-independent of the big three cloud providers. This ensures our monitoring isn't affected by their outages.
