OnWebChange vs SolidPing

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.

SolidPing is an open-source uptime monitoring platform available as hosted cloud software or self-hosted software. It offers 40 check types, including HTTP, TCP, DNS, databases, email servers, Docker, Kubernetes, headless-browser and custom JavaScript checks, with intervals as frequent as every 10 seconds. The product lists monitoring from six locations, server monitoring and SSL expiry alerts. Alerts can reach a wide range of chat services, email, webhooks, PagerDuty, push services, SMS or voice through Twilio. Rotation schedules, overrides, iCal feeds and multi-step escalation policies are included even on Free. Public status pages can show sections, subscribers, incident updates, uptime and response-time metrics; custom domains are metered by plan. SolidPing also offers a REST API and MCP endpoint. The self-hosted version is a Go binary using SQLite or PostgreSQL, licensed under AGPL-3.0. Hosted plans run from Free to Scale, and hosted account, monitoring and incident data and backups are stored in France on OVHcloud. SolidPing states it does not currently hold ISO 27001 or SOC 2 certification.
