Check URL Now — Free HTTP & SSL Status Check
Quick answer
StillOnline Check URL Now runs a single external HTTP GET and optional SSL certificate read from the same probe network that powers paid monitoring. Enter any public http:// or https:// URL (we default to https:// when you omit the scheme). You get status code, latency, up/down, and for HTTPS—expiry date, days left, and issuer. No account required. This is a one-time snapshot, not 24/7 uptime monitoring.
Check a URL
How it works
- You submit a URL; we normalize it and block private IPs (SSRF-safe validation).
- Our probe sends
GETwithStillOnline-Probe/1.0, following redirects with re-validation on each hop. - For
https://URLs we open a TLS connection on port 443 and read the certificate. - Results appear in the panel below—rate limit 10 checks per 10 minutes per IP.
Disclaimer: This is a one-shot check from StillOnline probes. It does not replace continuous monitoring, alerting, or status pages. For checks every 5 minutes free, create an account.
FAQ
How do I check if a website is down right now?
Paste the URL above and click Check now. We probe from StillOnline infrastructure and show HTTP status and latency. For ongoing alerts, use StillOnline Free monitoring (1 URL, 5-minute interval).
Do you check SSL certificates?
Yes for https:// URLs. We show valid-until date, days remaining, and issuer when the TLS handshake succeeds.
How is this different from UptimeRobot?
UptimeRobot offers free ongoing monitors (many URLs, scheduled). StillOnline Check URL Now is a single snapshot without signup—useful to verify a URL once, then monitor it every 5 minutes with a hosted status page and MCP on Pro.
Do I need to register?
No. The tool is public. Rate limits apply to prevent abuse.
Can I monitor this URL automatically?
Yes—sign up free, add the URL as a health check, and get a status page plus owner alerts (Telegram, Slack, or email).
Need 24/7 monitoring?
Free: 1 URL, checks every 5 minutes, hosted status page.
