Free plan · No credit card · Checks every 12 hours

A competitor can change a price, promotion, stock message, or shipping promise at any time. Nythra monitors the exact public URLs you choose so your team can review a detected change instead of repeating manual checks.

Start with a page tied to a real decision

Competitor prices

Detect any visible price movement, require a minimum percentage, choose a direction, or use a threshold.

Product availability

Watch language such as in stock, sold out, preorder, or unavailable.

Promotions and bundles

Notice when public offer language, discount messaging, or bundles change.

Shipping and returns

Monitor public shipping thresholds, delivery promises, and return-policy pages.

What Nythra does for you

A watch built around the signal

Choose any price movement, a minimum percentage, one direction, a threshold, or availability.

Focused page targeting

Use keywords or Pro selectors to reduce noise from unrelated product-page updates.

A review step before action

Open the original URL and inspect retained change evidence before making a pricing or inventory decision.

Free checks every 12 hours. Pro supports 30 watches, 6-hour checks, precise targeting, webhooks, and managed-browser fallback.

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 alerts you to detected public-page changes. It does not scrape an entire catalog, automatically reprice products, or guarantee access to every third-party storefront.

Before you create the watch

Does Nythra automatically change my prices?

No. Nythra detects changes and sends alerts. Your team reviews the page and decides what action to take.

Can I alert only when a price drops?

Yes. Price-focused watches can alert on a detected decrease, optionally require a minimum percentage, or wait until the price crosses below a threshold.

Will it work on every store?

Not always. Some stores block automated access or render pages in ways that require a Pro fallback. A target site can still prevent monitoring.

Can Nythra monitor a full product catalog?

Not automatically. Each active watch targets a specific supported URL, and account watch limits apply.
