Getting started

DeltaWatch makes it straightforward to monitor any webpage, API, or PDF for changes. This guide walks you through the basics.

Create your account

  1. Head to app.deltawatch.ing and create an account.
  2. You’ll land in your default workspace with an empty Watchlist.

Add your first watch

  1. Click Add watch in your Watchlist.
  2. Paste the URL you want to monitor — this can be a webpage, REST API endpoint, or a direct link to a PDF.
  3. Set your check interval. The free Ping plan supports 3-hour intervals; paid plans go down to 5 minutes.
  4. Click Save.

DeltaWatch will fetch the page immediately and store the first snapshot.

Configure notifications

  1. Open your watch and navigate to the Notifications tab.
  2. Add one or more notification channels — email, Slack, Discord, Telegram, Microsoft Teams, or a custom webhook.
  3. Optionally add conditions to filter out noise. For example, only alert when a specific keyword appears or when the change percentage exceeds a threshold.

See the notifications guide for setup details for each channel.

See your first diff

Once a change is detected on the next check cycle, DeltaWatch will:

  • Send you a notification through your configured channels.
  • Store the new snapshot alongside the previous one.
  • Generate a diff you can view in the History tab.

The diff viewer supports inline and side-by-side modes with word-level highlighting.
