OnChange vs Wachete
Wachete has been around since 2014 and runs a no-frills cloud monitor with email and SMS alerts. OnChange is the developer-first equivalent, with faster checks, API and accessibility coverage, and modern alerting.
Both tools poll URLs and tell you when something changes. The differences are speed, breadth, and how the alert flows into the rest of your stack. If you want a basic always-on watcher with email notifications, Wachete works. If you want sub-minute checks, alerts in Slack and Discord, API monitoring, and a UI built for 2026, OnChange is the modern upgrade.

Choose the product that fits the work
Pick OnChange if
- You need sub-minute scheduled checks
- Your alerts should land in Slack and Discord, not just inbox or SMS
- You want visual diffs, API monitoring, and accessibility scans in one tool
- You ship code and want to investigate changes alongside commits from a linked repository
- You want a clean, modern UI your team will actually open every day
- You need a REST API to programmatically manage monitors from CI or scripts
Pick Wachete if
- You only need basic email or SMS alerts on a small number of pages
- You're already a Wachete customer with hundreds of monitors and migration risk is high
- Daily or hourly checks are good enough; sub-minute is overkill for your use case
- You don't need API monitoring, accessibility scans, or commit attribution
