THE PRODUCT
Rental listings go in minutes, and the people who get them are the ones who saw them first.
Notifio watches the searches you already use, checks them every 30 seconds and alerts you as soon as something new appears, with a direct link to the listing. It runs on your own machine rather than as a service that logs in on your behalf, and it can even send your enquiry for you.
WHAT IT DOES
Any site, any filter
Paste the URL of any rental search and go. No per-site setup.
Checked every 30 seconds
Searches are polled continuously, with randomised delays.
Instant alerts
Email and desktop notifications, each with a direct link to the new listing.
Logins handled
Works with sites that need you to be signed in, managing sessions automatically.
Auto-reply
Show it how to reply on a site once, and it fills in the contact form with your details for every new listing.
Lives in your tray
Runs quietly in the background, with a live status for each search and a 'check now' button.

- 01
No integrations needed
Each search is rendered in a real browser and compared with the previous check, so Notifio works on any site without custom scrapers.
- 02
Resilient checking
Challenge pages are waited out rather than counted as failures, and each site gets its own backoff, so monitoring keeps going without hammering anyone.
- 03
Record once, replay safely
Auto-reply records the steps you take to send an enquiry and replays them, with a ledger that prevents duplicate messages and enforces rate limits.
- 04
Local first
Personal details are encrypted with the operating system's secure storage, the licence works offline, and alert emails go out from the server so the app never handles mail itself.
