The Modern Alternative to UptimeRobot
DownWarning was built for teams who have outgrown basic ping monitoring. If you're evaluating alternatives to UptimeRobot, here is what sets DownWarning apart — Local Agents for private infrastructure, SSL certificate monitoring on every plan, and transparent pricing without per-contact upsells.
Local Agents for Private Infrastructure
Monitor internal APIs, databases, and services that aren't reachable from the public internet. Install a single binary inside your network and results stream securely to the dashboard.
Free SSL Certificate Monitoring
Track expiration dates and signature changes on every plan, including the free Starter tier. Get alerted weeks before a certificate expires.
Transparent, Predictable Pricing
Clear monthly tiers with no per-contact add-ons or hidden fees. Compare every plan side by side and upgrade only when you need more.
Multi-Channel Alerts Out of the Box
Slack, Telegram, Microsoft Teams, Email, and Webhooks are available on every plan — route incidents to the right team without extra integrations.
What you get with DownWarning
- Uptime checks: HTTP, HTTPS, Ping, and Port — with configurable intervals
- SSL monitoring: Included on every plan, including the free Starter tier
- Alert channels: Slack, Telegram, Teams, Email, and signed Webhooks
- Private infrastructure: Local Agents on Linux, macOS, and Windows (Pro and Scale plans)
Why teams switch to DownWarning
Basic ping monitoring is only half the story. Modern infrastructure spans internal services, queues, caches, and private APIs that the public internet can't reach — and every SSL certificate is a silent outage waiting to happen. DownWarning closes both gaps by default.
Start free on the Starter plan — no credit card required. Upgrade to Pro or Scale when you need Local Agents, longer data retention, or more monitors.
