UptimeRobot tells you when your site is down. Tink lives on your server, tells you why it's down, and helps you fix it. They're complementary tools — here's how they compare.
| Feature | Tink | UptimeRobot |
|---|---|---|
| Monitoring approach | Agent on server — full system visibility | External HTTP/ping checks |
| What it monitors | CPU, memory, disk, services, certs, logs, network | URL availability, response time, ports |
| Diagnosis | AI explains root cause in plain English | Down/up status only |
| Fix guidance | Proposes commands, explains reasoning, executes on approval | None — alerts only |
| Setup | One command: curl | sh | Add URLs in web dashboard |
| Pricing | Free (1 server), $9-29/mo per machine | Free (50 monitors), $7/mo (Pro) |
| Alert channels | Telegram, email, webhook | Email, SMS, Slack, webhook, and more |
| Agent required | Yes — lightweight (<20 MB RAM) | No — external monitoring |
| Internal service checks | Yes — port, process, health endpoint | Limited to externally reachable endpoints |
| SSL certificate monitoring | Yes — warns 7-14 days before expiry with fix steps | Yes — expiry alerts |
| Audit trail | Full — every scan, diagnosis, and action logged | Incident log only |
| Conversation interface | Telegram, CLI (Slack/Discord coming) | None |
UptimeRobot is an external watchdog. It pings your URLs from the outside and tells you when they stop responding. That's valuable — but it can't tell you why your site went down, and it can't help you fix it.
Tink is an internal mechanic. It runs on your server with full visibility into CPU, memory, disk, running services, and logs. When something breaks, it diagnoses the root cause (e.g., “Nginx stopped because disk is 97% full from accumulated access logs”) and guides you through the fix.
Many teams use both: UptimeRobot for external availability monitoring, and Tink for internal diagnostics and remediation.
UptimeRobot tells you “your site is down.” Tink tells you “Nginx crashed because the OOM killer terminated it — a Node.js process leaked 6 GB of memory. Here's how to restart Nginx and set memory limits on the Node process.”
Use UptimeRobot for the “is it up?” question. Use Tink for the “why is it down and how do I fix it?” question.
