FMLS IDX Real Estate Websites for Atlanta Agents & Brokers
A direct IDX feed from First Multiple Listing Service (FMLS) – Georgia’s oldest and largest MLS – built into a fast, semi-custom REALTOR® website with no third-party intermediary.
IDX Updated Every 10 Min
58,000+ FMLS Members
Georgia’s Oldest MLS - Est. 1957
How Your FMLS IDX Website Works
Your OSI IDX website connects directly to the FMLS data feed, so every listing your buyers see – from a bungalow in Decatur to new construction in Forsyth County – is pulled straight from the source and refreshed automatically every 10 minutes. There’s no third-party intermediary sitting between your site and the MLS, which means faster updates and more accurate data than sites built on outdated feed technology. As one of the largest and oldest MLSs in the Southeast, FMLS covers a sprawling, competitive market — and your site needs to keep pace. That’s why we build REALTOR® websites that are fast, mobile-first, and designed to convert Atlanta-area buyers and sellers into leads, not just visitors.

Why Agents Choose OSI IDX
A direct FMLS feed is only part of the equation. Here’s what sets an OSI IDX website apart from other FMLS IDX vendors:
- Flat, all-inclusive pricing. One price covers your website, hosting, and your FMLS 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 listings update on my FMLS IDX website?
Your OSI IDX website pulls listings directly from the FMLS feed and refreshes automatically every 10 minutes, so buyers always see current inventory.
How long does it take to launch my FMLS IDX website?
Most sites launch in 5–7 business days. We’ll work with you on content and design preferences so your site reflects your brand from day one.
How much does the FMLS IDX feed cost?
The FMLS IDX feed is $25/month, billed separately from your website plan. See full pricing details
Do I need both FMLS and GAMLS on my website?
Many Atlanta-area agents belong to both MLSs. If you’re a member of both, we can add a second IDX feed to your site so your listings reflect your full coverage area.
Does OSI IDX cover FMLS’s entire service area, including North Georgia?
Yes. Your FMLS feed covers the same footprint FMLS itself serves – metro Atlanta and the surrounding North Georgia counties – so your site’s search results match what you see in FMLS Matrix.
Is FMLS a good fit for a new Atlanta-area agent’s first IDX website?
Yes. As Georgia’s oldest and largest MLS, FMLS gives your site access to the deepest local listing inventory in the metro, which is exactly what a new site needs to be useful to buyers on day one.
