Real Estate Software: MLS/IDX, RESO Web API, and RETS

We build brokerage and proptech systems - fast property search, MLS/IDX data pipelines, lead routing, and back-office portals - supporting the RESO Data Dictionary and modern APIs.

Real estate MLS/IDX software

Overview

Brokerage & proptech platforms that respect MLS rules

We implement RESO Web API and maintain legacy RETS pipelines where required - normalizing to the RESO Data Dictionary, handling media, and mapping fields across multiple MLSs. Portals deliver quick property search, saved listings, alerts, and lead capture connected to your CRM.

Stack: PHP, Python, and JavaScript (React/Next.js) on AWS; queues for ingestion; search indexes for fast queries; and CI/CD with monitoring so updates are seamless.

Capabilities

What we build for real estate teams

RESO Web API & RETS

Ingestion, field mapping to RESO dictionary, update syncs, media downloads, error handling, and reconciliation across multiple MLSs.

IDX Property Search

Fast search with filters (price, beds/baths, status, HOA, school zone), map mode, saved searches, favorites, and alerting (email/SMS/push).

Leads & Routing

Lead capture, scoring, round-robin routing, agent assignment windows, and CRM integrations.

Listing Management

Broker admin tools for manual listings, open houses, price updates, media galleries, and status changes.

Maps & Neighborhoods

Tile layers, draw-a-shape search, school boundaries, commute times, and polygon-based alerts with caching.

Analytics & SEO

Market stats, listing performance, agent KPIs, schema markup, city/ZIP/neighborhood landing pages, and analytics.

Integrations & Compliance

Play nicely with MLS, portals, and broker systems

MLS & IDX

RESO Web API, RETS (where needed), standardized fields, media/CDN, and MLS display rules including attribution and disclaimers.

Broker Systems

CRM, e-sign, showing services, and accounting exports with audit trails and user roles.

Maps & Geodata

Basemaps, geocoding, polygons, and caching for quick tiles & clusters.

Privacy & Policies

Consent & opt-in, retention, audit logs, and secure media links - aligned with brokerage policies and MLS agreements.

Approach

Reliable ingestion and search, with clear UX

We design listing ingestion for resilience: delta pulls, retries, and media reconciliation. Search is hybrid - text + features + map - tuned for speed and relevance with caching and pagination that scales.

  • Normalize MLS feeds to RESO Data Dictionary
  • Delta syncs, job queues, and monitoring dashboards
  • Property search: filters, map clusters, saved searches & alerts
  • Lead capture, CRM handoff, and response SLAs
  • Audit trails and role-based access for brokers/agents
RESO ingestion and IDX search flow

Typical flow: MLS API/RETS → staging → normalization → search index → portal & CRM.
