One Platform for All Your MLS Data

RESO DB is the modern data platform for real estate organizations. We handle the complexity of MLS integrations so you can focus on building great products and making better decisions.

From chaos to clarity: Multiple MLS feeds, inconsistent schemas, and constant maintenance become a single, reliable SQL API with standardized data.

Core Capabilities

Everything you need to aggregate, normalize, and query real estate data at scale.

Multi-MLS Aggregation

Connect to multiple MLS sources through a single platform. We support the major data access protocols used across the industry.

  • RETS Protocol - Traditional RETS feeds with full metadata support
  • Bridge API - Modern RESTful API connections
  • Spark API - Spark/Flexmls API integration
  • Automatic sync, error recovery, and schema updates

RESO 2.0 Normalization

Every listing, agent, and office record is transformed to the RESO Data Dictionary 2.0 standard.

  • Consistent field names across all your sources
  • Standardized enumerations for status, property type, and more
  • Predictable data types for reliable development
  • Cross-MLS queries without source-specific logic

SQL API on ClickHouse

Our query engine is built on ClickHouse, the industry-leading columnar database for analytics.

  • Sub-second queries on millions of records
  • Standard SQL syntax your team already knows
  • Complex aggregations for market analysis
  • No infrastructure management required
