How this service works
Change watch for cms detect: runs the check and compares it with the result from your previous call for the same domain (kept 90 days), returning the current answer, changed true/false, exactly which fields changed with before/after values, and when it was last seen. Call it on a schedule to be told when cms and platform detection changes. $0.01 per check.
Output
Returns the current CMS and platform detection result for the domain, a boolean 'changed' flag indicating whether results differ from the previous call, a list of changed fields each with before and after values, and a timestamp of when the result was last seen. Previous results are retained for 90 days.
Example use cases
Competitor CMS migration alert
“Watch competitor.com for me and tell me the moment its CMS detection changes — I want to know if they switch away from WordPress, and I need the before and after values for every field that changed.”
Client site re-platform verification
“My client just migrated their site from Magento to Shopify at clientstore.com — can you run a CMS change watch on it now and confirm the platform detection has actually updated, showing me what changed?”
Scheduled tech-stack monitoring
“Set up a recurring check on mybrand.io so that every time the CMS or platform detection result changes, I get a report with exactly which fields are different and what the previous values were.”

Endpoint
GEThttps://intel.rallylive.ca/watch/site/cmsWhen to prefer
Choose this endpoint when you need to detect and be notified of changes to a site's CMS or technology platform over time, rather than just knowing the current state. It is ideal for scheduled polling workflows where you want field-level diffs with before/after values without managing your own state — the service stores the last result for 90 days. Prefer it over a one-shot CMS detection call when change detection and auditability are the goal.
Side effects
- Domain not reachable or returns non-200 status — detection may fail or return partial results
- First call for a domain has no prior result to compare against — 'changed' will be null or false with no diff
- Domain resolves but CMS is undetectable — returns null/unknown CMS with no change data
- Prior result expired after 90 days — treated as a fresh first call with no diff available
- Malformed domain input — returns validation error
