How Your Bay East & CCAR IDX Website Works
OSI IDX builds real estate websites for agents and brokers who work Bay East and CCAR listings, pulling directly from the shared Paragon MLS feed that both associations run on. Whether your primary membership is with Bay East, CCAR, or both, your website displays the same unified East Bay data set — no duplicate feeds, no juggling two separate IDX setups. As one of the real estate websites for REALTORS® built specifically around flat pricing and no CRM lock-in, OSI IDX gives East Bay agents a faster, more flexible alternative to the big all-in-one platforms.

Why Agents Choose OSI IDX
A direct Bay East CCAR feed is only part of the equation. Here’s what sets an OSI IDX website apart from other Bay East CCAR IDX vendors:
- Flat, all-inclusive pricing — no hidden fees, no surprise upgrades. See full pricing details
- No CRM lock-in — connect the CRM you already use instead of being forced into ours. See CRM integrations
- Semi-custom design — a site that looks like yours, not a generic template. Browse sample websites
- US-based, real support — talk to an actual person when you need help, not a ticket queue.
- Backed by OSI Express since 1982 — built by a family-owned real estate technology company, not a VC-backed startup chasing growth targets.
