What it is

Tallwatch monitors websites and APIs from multiple regions and opens an incident when at least two regions report the same failure in a check round. Check types include HTTP, keyword, ping, TCP, DNS, SSL, and heartbeat, with probes in Virginia, Frankfurt, Singapore, Sydney, São Paulo, and Oregon. Alerts can be routed to email, Slack, Microsoft Teams, Telegram, Discord, PagerDuty, and signed webhooks. On-call rotations and escalation policies direct incidents to responders until acknowledgment. Public or private status pages can use a custom domain and include incident history and email or RSS subscribers. Developers can manage monitors and triage incidents using a REST API, CLI, or hosted MCP endpoint. The CLI runs on macOS, Linux, and Windows and can import monitors from UptimeRobot. The free plan includes 10 monitors and 60-second checks from three regions. Pro costs $11.99 a month billed annually, or $14.99 a month billed monthly; Business is $19.99 a month billed annually, or $24.99 a month billed monthly. Tallwatch says it does not publish a formal customer uptime SLA with automatic credits.
