Competitor prices, stock levels, policy updates, changelogs — anything published on the web can be watched. Fingerprint any page below for free, then let DeskUptime re-check it on a schedule and alert you the moment it changes.
Fingerprint a page now See DeskUptime →Enter any URL. We compute the SHA-256 hash of the page's HTML — compare it to a previous run and you know exactly whether the content changed.
Prefer the terminal? Do the same yourself:
curl -sL https://example.com/pricing | sha256sum # run again later — a different hash means the page changed # or let DeskUptime do it continuously: deskuptime watch https://example.com/pricing --interval 300
Nobody re-reads a page they read last month. That is precisely when the important edits happen.
Providers update terms, SLAs and privacy policies with a blog post nobody reads. The new clause applies whether you noticed or not.
Supplier price lists, competitor plans, drop pages and restocks move without announcement. First one to see the change wins.
API deprecations, breaking changelog entries, incident post-mortems — published once, on a page you'll only visit when it's already too late.
Content monitoring exists as SaaS. Here is how it compares.
| Cloud monitors (Visualping, Distill…) | Self-hosted diff tools | DeskUptime | |
|---|---|---|---|
| Cost | $9–30/month | Free + your server time | $19 once, then $0 |
| Who fetches the pages | Their servers (shared IPs) | Your server | Your own machine |
| Setup | Account + plan limits | Docker/cron to maintain | Install, add URL, done |
| Uptime & SSL checks too | Separate products | You build it | Included |
| Privacy | They see everything you watch | Yours | Yours — checks run locally |
One $19 license covers unlimited URLs on up to 3 machines. No monthly fee, ever.
The free checker answers “has it changed by now?”. DeskUptime flips the question around.
# Watch a page and get notified when its content changes: deskuptime watch https://competitor.com/pricing --interval 300 # Combine with uptime and SSL in one config file: deskuptime start # runs everything in ~/.deskuptime/config.toml
Fetch it twice and compare fingerprints. The checker above computes the SHA-256 hash of the raw HTML — a different hash than your earlier check means the content changed. Save today's hash, re-run tomorrow.
Raw HTML hashing is strict. CSRF tokens, session nonces, cache-busters and rotating ad slots all alter the bytes without changing anything visible. The DeskUptime desktop app lets you exclude parts of the page so alerts only fire for real changes.
Pricing pages, product/restock pages, documentation changelogs, terms of service, job postings, tender and permit notices, university admission pages — any public page whose change would matter to you.
An occasional check of a public page is what every browser does on every visit. Use sensible intervals (minutes, not milliseconds), respect robots.txt where applicable, and don't try to bypass paywalls or login walls — DeskUptime only sees what an anonymous visitor sees.
Yes. A URL is a URL — WordPress, Shopify, Webflow, Squarespace, Notion, a PDF behind a link, or hand-written HTML. Nothing is installed on the target site and no CMS-specific knowledge is needed.
