OnWebChange vs Wachete

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.

Wachete monitors web pages for changes and sends alerts by email or phone notification. It can track a whole page or selected sections, including dynamic pages and pages requiring login credentials. It can also crawl linked sub-pages to the third level and monitor those it finds. For documents, it extracts text from PDF, XLSX, Word, and DOCX files; other file types can be checked for size or last-modified changes. Alerts can go to mobile push, Slack, Google Chat, Discord, Telegram, and Microsoft Teams, as well as email. Integrations include Zapier, Pabbly Connect, a REST API, webhooks, and an MCP server for AI assistants such as Claude. Wachete says it retains up to 12 months of history, charts numeric values for up to five years, and supports spreadsheet downloads. Monitoring runs on its servers in locations around the world. The service lists a free plan and a seven-day trial. There is no monthly check cap, but the number of monitored pages and checking interval depend on the plan.
