How Your California Regional MLS (CRMLS) IDX Website Works
If you’re a real estate agent or broker working with CRMLS listings, your website needs to keep pace with California’s largest and most active market. OSI IDX builds real estate websites with a direct California Regional MLS feed, giving your visitors accurate, up-to-date listings without the delays or clunky widgets that come with generic templates. Every site is semi-custom, built on a platform you control, with no CRM lock-in forcing you into tools you don’t want. Whether you’re working Los Angeles, Orange County, San Diego, or the Central Coast, your CRMLS listings stay current automatically – so you can focus on clients instead of managing plugins.

Why Agents Choose OSI IDX
A direct CRMLS feed is only part of the equation. Here’s what sets an OSI IDX website apart from other CRMLS IDX vendors:
- Flat, all-inclusive pricing. One price covers your website, hosting, and your CRMLS IDX feed – no tiered plans or feature upsells. See full pricing details
- No CRM lock-in. Keep the CRM you already use. Leads captured on your site sync directly, so you’re never forced onto a proprietary platform. See CRM integrations
- Semi-custom design. Your site is built around your brand, not a one-size-fits-all template shared with hundreds of other agents. Browse sample websites
- Family-owned since 1982. OSI IDX is a product of OSI Express, a family-run real estate technology company with over four decades in the industry – not a VC-backed startup.
- US-based, real support. Talk to a real person on our support team, based in the US, not an offshore call center or a chatbot.
Frequently Asked Questions
How often do CRMLS listings update on my website?
Your OSI IDX website pulls listings directly from the California Regional MLS (CRMLS) feed and refreshes automatically every 10 minutes, so buyers always see current inventory.
How long does it take to launch a CRMLS IDX website?
Most agents and brokers go live within 5–7 business days once design preferences are finalized.
How much does the CRMLS IDX feed cost?
The CRMLS IDX feed is $25/month, included as part of your flat, all-inclusive OSI IDX pricing – no hidden add-ons. See full pricing details
Will my site show only my own listings, or all CRMLS listings?
Your website can display the full range of active CRMLS listings across your service area, not just your personal listings, giving buyers a complete search experience.
Do I need to belong to a CRMLS-participating Association or Board?
Yes. Since CRMLS access is organized through its member Associations and Boards, you’ll need an active CRMLS membership through one of them before your IDX feed can go live.
Can I switch to OSI IDX if I already have a CRMLS website with another vendor?
Yes. OSI IDX can set up your CRMLS feed independently of your current provider, and most agents switch without any interruption to their existing listings.
