What is updown.io?
updown.io is a minimalist website monitoring service founded in France in 2012. It does one thing well: cheap, pay-as-you-go HTTP and SSL uptime monitoring, billed by credits so you only pay for the check frequency you use. New accounts get 100,000 free credits, and a single site checked every minute costs roughly EUR 0.6 per month. It is a developer favourite for its simplicity and price.
When updown.io is the right pick
Choose updown.io when you want dead-simple, dirt-cheap uptime and SSL-expiry checks for a few endpoints and nothing else. Its pay-as-you-go credit model is ideal for hobby projects and small sites where a flat monthly fee feels like overkill, and the clean public status pages are a nice bonus.
Where updown.io leaves gaps
updown.io is deliberately minimal. It has no real load testing, no Lighthouse Core Web Vitals, and no multi-step API monitoring with assertions, it is a single-request HTTP ping plus SSL check. When you need to validate response bodies, simulate traffic, or measure page-speed depth, you outgrow it quickly.
