In their own words
OnWebChange
OnWebChange monitors webpages and sends alerts when it detects changes. Users can track particular page elements, including prices, headlines and listings, and monitor content on sites that load dynamically with JavaScript. It also checks PDFs, images, text files and other online documents, and can reach login-protected pages using custom headers. Notifications are available by email, mobile notification and webhook; Pushover is named as a third-party mobile notification service for Android and iOS. Checks can run as often as every five minutes. The service can translate tracked content and summarize updates, while groups, labels, pause and resume controls, and CSV import and export help manage trackers. Access is listed for Android, iOS, web and API. The Free plan is free and includes three page trackers with basic daily monitoring. Lite is €0.89 a month, and Standard is €2.79 a month with unlimited trackers. Documentation, video tutorials, email and member support enquiries are available.
Tallwatch
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.
