How Your BAREIS MLS IDX Website Works
North Bay REALTORS® need an IDX website that keeps pace with one of Northern California’s most competitive real estate markets. OSI IDX builds IDX real estate websites with a direct BAREIS MLS® feed, giving your buyers accurate, up-to-date listings across Marin, Sonoma, Napa, Solano, and Mendocino Counties – without the bloated pricing or CRM lock-in of the big all-in-one platforms.
Whether you’re working the Wine Country luxury market in Napa and Sonoma, coastal listings along Mendocino’s North Coast, or commuter-friendly homes in Marin and Solano, your website should reflect the areas you actually serve. OSI IDX gives you a semi-custom site built around your brand, backed by OSI Express, a family-owned real estate technology company operating since 1982.

- Flat, all-inclusive pricing — no hidden tiers, no surprise upgrade fees. See pricing details
- No CRM lock-in — connect the CRM you already use instead of being forced into ours. See CRM integrations

- Backed by OSI Express since 1982 — built by OSI Express, a family-owned real estate technology company, not a VC-backed startup chasing growth targets.
