Built around the listing data
The core of any real estate platform is the listing feed. Depending on your MLS and its rules, that means an IDX or RESO Web API connection, a scheduled sync into your own database, and display that follows the feed’s compliance requirements. Owning the synced data is what makes fast search and custom features possible.
On top of the data sit the tools buyers and agents use: map and filter search, saved searches with email alerts, favourites, mortgage and affordability calculators, and lead forms that land in a CRM or an agent dashboard with the property attached.
For an individual agent who mainly needs a fast, well-ranked website, the real estate website design page is the better fit. This page is for projects where the software is the product.
What’s included
IDX / MLS integration
Listing feeds synced to your own database, displayed within your MLS’s rules.
Map search
Search by map area, price, beds, baths and property type, fast enough to feel instant.
Saved searches & alerts
Buyer accounts with favourites and email alerts when new matching listings appear.
Agent dashboards
Lead inboxes, assignment rules and activity history for brokers and teams.
Calculators
Mortgage and affordability tools that keep buyers on your site instead of a portal.
Owned code and data
One flat project fee. The platform, the database and the leads belong to you.
Frequently asked questions
Can you connect to my MLS?
Usually, through an approved IDX vendor or the MLS’s RESO Web API. Access is granted by the MLS to the broker, so we confirm the options for your market during the consultation.
Is this the same as an agent website?
No. An agent website is mainly about presenting you and ranking locally. A platform adds listing search, buyer accounts and lead routing. If you need the first, see real estate website design.
How is it priced?
As one flat project fee, quoted after scoping. Web applications are scoped individually; the published starting point for web applications is on the pricing page.
Who owns the leads and data?
You do. Everything is stored in your own database on hosting in your name.
Pricing, timeline & ownership
