Important pages rarely announce every update. Nythra checks the URL on your schedule and compares its monitored content with the previous successful result.

Start with a page tied to a real decision

Price and availability

Watch a product, promotion, or public pricing page for a relevant change.

Jobs and new listings

Monitor a careers, housing, grant, ticket, or other listings page.

Policies and deadlines

Track selected public terms, guidance, application, or deadline pages.

Your own important pages

Notice unexpected visible content or technical-health changes on a key URL.

What Nythra does for you

Choose why you are watching

Start with page change, price or availability, new content, or specific information.

Set a practical condition

Alert on any matching change or use supported text, price, and availability conditions.

Review the evidence

Open the original URL and inspect retained text changes and available visual evidence.

3 free watches checked every 12 hours, email alerts, technical health checks, and retained change history.

From URL to useful alert in three steps

STEP 01

Paste the exact URL

Choose the public page that contains the information you need to follow.

STEP 02

Choose what should trigger

Select the watch goal, condition, check frequency, and notification destination.

STEP 03

Review the source

Open a detected change, inspect the evidence, and verify the current page before acting.

Clear expectations

Nythra cannot guarantee access to every site or prove that every detected change is important. Signed-in and highly dynamic pages may require a Pro browser option or may remain unavailable.

Before you create the watch

What pages can Nythra monitor?

Nythra can monitor supported public HTTP and HTTPS pages. Customer-authorized signed-in pages may require the Pro Chrome Connector, and a target site can still prevent access.

How often are pages checked?

Free watches can run every 12 hours. Pro watches can run every 6 hours, subject to monthly plan allowances.

Can I monitor only part of a page?

Yes. Use focus words, or use Pro CSS selector and attribute targeting for a precise page value.

How are alerts delivered?

Nythra supports content-change email alerts. Pro also supports webhooks.

Simple, transparent pricing
