Stellar MLS is the largest MLS in Florida and Puerto Rico, serving more than 80,000 real estate professionals across 19 REALTOR associations.
It operated as My Florida Regional MLS until the June 2019 rebrand, so older vendor paperwork still calls it MFRMLS.
Stellar MLS operated as My Florida Regional MLS (MFRMLS) until June 4, 2019, when it took the Stellar name. Same organization, same lineage, so if you still see MFRMLS on an old vendor form, that's this MLS. The rebrand announcement described an MLS serving nearly 60,000 customers. Stellar's current figure is more than 80,000.
Stellar is owned by the REALTOR associations it serves. On its own shareholders page, shareholder organizations sit on the board of directors and vote on key initiatives, with board seats appointed in proportion to each association's membership. Associations under 400 members come in as customer organizations instead: same tools, no board vote, a seat on the MLS Advisory Council.
Lake Wales and the Puerto Rico Association of REALTORS are the two customer organizations. Stellar itself runs out of Altamonte Springs, just north of Orlando.
On scale, Stellar's about page puts it at more than 80,000 real estate professionals served across 19 REALTOR associations. That feed is behind most of the Florida listings a buyer sees on agent websites and national portals, which is exactly why getting it onto your own domain is worth the paperwork.
Getting its listings onto a WordPress site takes three things: active Stellar participation through your broker or association, a feed credential from one of Stellar's two RESO Web API gateways, MLS Grid or Bridge API, and a plugin to pull the data across.
Both gateways are RESO Data Dictionary compliant, and both run through a three-party agreement between the broker, the vendor and Stellar MLS.
MLS Import is the plugin side of that. It syncs the feed hourly into native, indexable WordPress posts on your own domain, works with any theme, and costs $49 a month after a 30-day free trial. No iframe, no vendor subdomain, no listings parked on somebody else's servers.
The Puerto Rico Association of REALTORS (PRAR) is a full Stellar customer organization, not a side partnership and not a data-share arrangement. A broker in San Juan subscribes to the same MLS as a broker in Orlando, under the same rules, pulling the same RESO Data Dictionary field set through the same two gateways.
Stellar backs that up in the account tools rather than stopping at the org chart. Stellar's Stellar Central FAQ put the dashboard's Spanish version live on March 18, 2025, and says PRAR customers receive the EULA in Spanish.
For anyone building a site for a Puerto Rico brokerage, that matters in a practical way: the agents you onboard are already working inside an MLS that speaks their language, and Puerto Rico sits inside the same MLS rather than a separate regional system bolted onto one.
Universal Consulting Opportunities (UCO) is Stellar's international MLS-consulting subsidiary, launched in 2024. It has relationships across Asia, Africa, the Middle East, Latin America and Europe, and partnerships with CEPI (the European Association of Real Estate Professions), FIABCI (the International Real Estate Federation) and CILA (the Latin American Real Estate Confederation).
NAR India selected UCO to advise on building that country's first MLS. Merri Jo Cowen, Stellar's CEO from 2008 to March 2026, moved into UCO full time in the 2026 leadership transition, which tells you how much weight Stellar puts behind it.
Closer to home, Stellar also sits inside a three-way reciprocal data-share network with CRMLS and Bright MLS, announced jointly on July 8, 2025 and covered by WAV Group two days later.
Stellar's reciprocals page, last updated May 2026, puts the wider footprint at a referral network of over 444,000 professionals, 11 states and territories, and 17 countries. CRMLS and Bright are the headline partners, but the list runs wider: Miami REALTORS, live September 30, 2025, plus BeachesMLS, State-Wide MLS in Rhode Island, and OMNI MLS across Latin America.
Stellar runs on Matrix, the MLS platform from Cotality (formerly CoreLogic). Stellar's product page puts Matrix at 110+ multiple listing organizations and more than 1 million end users, handling over 1.6 billion sub-second page loads each month. Two lockbox systems integrate with it, Supra and SentriLock, and a subscriber picks one rather than carrying both.
Stellar, CRMLS and Bright MLS all run on Matrix, which is why the three-way data share could be switched on as a built-in Matrix capability instead of a custom integration. For your import, the platform matters less than what it emits, but it does tell you something: a system at that scale doesn't get to rewrite its data model on a whim, so the feed you map today behaves the same way next quarter.
Stellar Central at central.stellarmls.com is the sign-in point, included free with a subscription. It carries listing-status notifications for price changes, pending, expired and sold, multi-factor authentication, and the Spanish toggle described above. It's also where a subscriber launches Matrix, so it's the single door to everything else.
The wider subscription bundles more than 30 tools at no extra charge, including Cloud CMA, Remine, TransactionDesk and the client-facing OneHome portal. None of those reach the data feed, but they set what your agents expect a listing page to look like.
Worth a look before you sign off on templates, because the gap between what an agent sees in Matrix and what your WordPress theme renders is where most "the site is missing data" support tickets actually come from.
Stellar's data delivery page calls it a Proud Member of RESO, and its API options page says both gateways, MLS Grid and Bridge API, are RESO Data Dictionary compliant.
Why any of this matters to an import: a Data Dictionary compliant feed means field names map the same way every time. That's the difference between an hourly sync that just runs and a developer reverse-engineering a proprietary export every time the MLS changes something.
It also means the mapping work you do for Stellar carries over if you ever add a second market, since a Data Dictionary field means the same thing at every MLS that implements it. You aren't learning a Stellar-shaped dialect, you're learning the standard.
Stellar publishes an association roster rather than a county map, so the roster is where to check whether your market is covered. Read the association names on its shareholders page and the counties fall straight out of them: counties such as Osceola, Polk, Lake, Sumter, Marion, Alachua, Volusia, Pasco, Sarasota, Manatee, Charlotte, DeSoto, Flagler and Citrus. Orlando comes in through the Orlando Regional association, and the Tampa Bay side through Suncoast Tampa, which reports Hillsborough and Pinellas together. That is a sample, not a certified complete list, and associations keep joining.
Puerto Rico is on the roster too, as a whole territory rather than a county. So the shape is Central Florida, the Gulf coast, Ocala and Gainesville, the Atlantic coast at Volusia and Flagler, and all of Puerto Rico. In 2024, 50.8% of single-family homes sold in Florida were entered into Stellar MLS, which is where the "1 in 2" figure on Stellar's pages comes from.
Stellar's join page states that in 2024 it had residential sales in 65 of 67 Florida counties. That counts sales, not associations, so check the roster above before assuming a given county has a Stellar association behind it.
And one boundary to know before you scope a site. Southeast Florida is MIAMI Association of REALTORS territory, a separate MLS with its own credentials, and South Florida adds BeachesMLS. Stellar subscribers reach both through the reciprocal agreements listed on Stellar's reciprocals page, but the API feeds are not merged.
You can't sign up with Stellar MLS directly the way you would with a software product. Access runs through the REALTOR associations Stellar serves, with one narrow exception for people holding no REALTOR membership at all. Which door you use depends on your role and on whether your broker is already in.
Your broker has to be a Stellar participant first. Once that's in place, you join through the broker's REALTOR association, one of the 19 Stellar serves.
Join through one of Stellar's 19 associations. Your licensed agents then join Stellar too, or another REALTOR-owned MLS you belong to, under MLS of Choice.
Same association path as an agent, or a direct Thompson Appraiser subscription if you would rather not attach REALTOR membership to it.
Open only if you hold no REALTOR association membership anywhere in the country. No REALTOR association benefits come with it, and if the principal broker is on Thompson, everyone under them must be too.
Stellar delivers listing data over the RESO Web API, and its own API options page makes the case in practical terms: web APIs are standard tooling across the industry, so any developer can connect one without learning a specialist system first.
That keeps the cost of adding a real estate feed down and the timeline short, whether you're hiring a contractor for a weekend or wiring it up yourself. Two gateways carry that data, and choosing between them is the first real decision a developer makes. Everything in the table below comes from Stellar's own data delivery page and API options page.

Technical docs: Bridge Interactive platform docs, and account signup at bridgedataoutput.com/register
One thing that catches people out: listings obtained through Stellar's reciprocal MLS access agreements don't flow into your own IDX feed.
They are search and view only inside Matrix, so they never reach your site, and MLS Import cannot import what the feed does not send.
Stellar runs a second, deeper mechanism alongside those, Integrated Data Shares, searchable directly inside Matrix without a separate tab, currently with FMLS in Georgia and Gulf Coast MLS in Alabama.
Either way, what your site can publish is what your own IDX feed carries. Vendor onboarding questions go to [email protected].
Confirm active Stellar MLS participation through your broker or association. No membership, no feed.
Choose MLS Grid or Bridge API using the comparison above.
Complete the three-party agreement between the Broker, the Vendor (an in-house developer or a plugin) and Stellar MLS. You'll need to demonstrate a working application, or request sample data if you're still building.
Receive your API credentials once approved, returning listing data in the RESO Data Dictionary format.
Enter those credentials in MLS Import and start an hourly sync into native WordPress posts.
Most WordPress site owners need exactly one of these four feed types, all four defined on Stellar's data delivery page, fees included. IDX is the public one, and it carries no Stellar fee beyond the standard subscription.
Stellar is explicit that these are two separate channels, and mixing them up is where site owners get surprised. IDX is the defined set of fields authorized for public display on a participant's or agent's own website. Syndication is broker-authorized distribution to third-party consumer portals: Realtor.com, Homesnap, Homes.com, Apartments.com, Zillow Rentals and ListHub-connected sites. A broker controls syndication destination by destination.
IDX doesn't work that way, and here's the rule that matters most for your site. A brokerage can opt out of IDX entirely, but once opted in it cannot selectively opt out of individual IDX-powered websites. So a competing brokerage in your market can't keep its listings off your site specifically while leaving them on everyone else's. Either they're in the IDX pool or they're out of it.
Three fields decide how far a listing travels. "Internet Yes/No" is the full opt-out: set to No, the listing appears on no IDX feed and no consumer portal. A separate IDX/VOW field toggles those channels independently, along with comment feeds and automated valuation models. "Distribute To" controls third-party consumer sites listing by listing.
One rule overrides the rest: a broker's office-level opt-out always beats an agent's listing-level opt-in. The full field list is on Stellar's listing distribution page. None of this is something your site controls, and that's the useful part: if a listing you expected never appears, the answer is almost always one of these three fields on the listing itself, not a broken sync.
Per Stellar's listing compensation FAQ, all compensation fields, and any mention of compensation in remarks, photos, attachments or showing instructions, were removed from the Stellar MLS system on August 6, 2024. A broker may still display compensation for their own brokerage's own listings on their own IDX-fed website. Never for another brokerage's listings, and MLS data may never be used to build a platform aggregating compensation offers across brokerages.
Seller concessions are a separate field on a separate date: those came out August 27, 2024, and for concessions a dollar amount, though not a percentage, may still be disclosed in remarks. That exception never extends to buyer-broker compensation. A signed Buyer Broker Agreement is also required before touring a residential property, effective the same August 6, 2024.
Several of Stellar's photo rules show up on a public site. A pool is not an acceptable "water view" photo. Floor plans are allowed as images.
Lifestyle photos featuring people, including people in costume, are not allowed. And when a listing goes off-market, every photo except the primary one is hidden from public view, which matters if you plan a sold-listings archive on the site.
The rule with the biggest effect on what lands in your feed is Matrix Media Privacy, updated July 9, 2024. A listing agent marks each photo and supplement either Public, which can reach OneHome, the client portal and third-party sites depending on distribution settings, or Private, meaning MLS users only.
Private images never leave the MLS, so a listing can land on your site with far fewer photos than the agent uploaded. The primary photo has its own requirement under Article 4.5: it has to be property-centric. Build your gallery for a variable photo count, not a fixed grid.
Two invoices, not one. Stellar MLS bills its own base subscription fee, the same figure nationwide, and your local REALTOR association bills its own Local Service Center (LSC) add-on separately. The add-on is the part that varies by association, which is why nobody publishes a single "what an agent pays" number. Stellar's own base cost is published and dated: $550 for 2026, up from $525 in 2025, per its own Annual Billing Information Packet.
Here is one association's published math, from GACAR's 2023-24 schedule. Stellar's base rate was lower in that cycle than it is today, so the figures below show how the fee is built, not what it totals this year.
Four more figures come straight from Stellar, off its 2026 billing resources and reciprocal listings pages, and apply regardless of association:
Broker Data Services: $75 per year, billed once per broker or participant, not per office or per agent, covering listing distribution and IDX feed use.
Reciprocal Listing fee: $125 per listing, for REALTORS from participating boards entering a listing into Stellar.
Credit card surcharge: 3%. Debit, ACH, money order and check carry none.
Reinstatement fee: $250 on any account suspended for non-payment.
Member Reactivation Fee: $150, the cheaper cousin, for a member inactive less than one full billing cycle. Go past that and you are back to paying the setup fee.
Timing matters as much as the amount, and the same Annual Billing packet sets the calendar. The cycle runs June 1 to May 31. For 2026, invoices became available May 5 and went overdue May 20, with no late fee assessed that year.
The last day to pay before suspension was June 3 at 5 p.m. ET, suspension landing June 4 with that $250 reinstatement fee. New joiners pay the setup fee plus a prorated amount to May 31, and MLS fees are non-refundable in full or pro rata. If you do chase a refund, chase the right invoice: Stellar handles its own base fee, while the LSC portion has to be requested from your local association directly.
Stellar's March 3, 2026 announcement named Shayne Fairley chief executive, succeeding Merri Jo Cowen, who had led the organization since 2008 and has moved into running UCO full time. Fairley had been COO since 2017, so this reads as continuity rather than a change of direction, and no operational or API impact was reported alongside it.
The part that matters if you are building on Stellar's feed is quieter. That same announcement notes Fairley was elected in 2026 to the Council of Multiple Listing Services board and also serves on the Real Estate Standards Organization board.
Stellar is not only consuming the RESO standard, it has a vote where changes to the Web API and the Data Dictionary get decided. For anyone whose site depends on that feed staying standards-compliant year after year, that's a more useful signal than any uptime promise.
Stellar welcomed the REALTORS Association of Citrus County as a corporate shareholder on July 22, 2026, per its news page. Citrus sits on the Gulf coast north of Pasco, so the footprint pushed up the coastline rather than inland. Stellar's own published association count still reads 19 and has not been restated since.
Matrix kept changing underneath all of it. Stellar's Matrix page, last updated July 8, 2026, records a redesigned Financial Calculator with interactive charts live since January 20, 2026, and a "Backups Requested" indicator added to pending listings.
Neither one touches a field mapping, and that's the part worth noticing. Stellar ships member-facing changes to Matrix regularly without disturbing the RESO Data Dictionary field set your import depends on, which is the kind of quiet underneath you want on a site you aren't planning to rebuild every year.
Your Stellar membership is billed by Stellar and your local association (see the fees section above). MLS Import is a separate, simpler line item: one plan, no tiers, no per-listing charge. It's a standalone plugin, so it works with any WordPress theme. The four real estate themes named earlier get deeper native integration, but you never have to switch themes to use it.
Stellar MLS is the largest MLS in Florida and Puerto Rico, serving more than 80,000 real estate professionals across 19 REALTOR associations. It operated as My Florida Regional MLS until the June 2019 rebrand.
MLS Import connects its RESO Web API feed to a WordPress site so those listings publish as native posts on your domain.
Three steps. Build on any WordPress theme, get a Stellar feed credential through MLS Grid or Bridge API after completing the three-party broker, vendor and Stellar agreement, then connect that credential to MLS Import.
Listings then sync hourly into posts you own and control.
Central and Southwest Florida plus all of Puerto Rico. Counties named in Stellar's association roster include Osceola, Polk, Lake, Marion, Alachua, Volusia, Pasco, Sarasota, Manatee, Charlotte and Citrus, with Orlando and Tampa covered through their regional associations.
MLS Import then brings in only the counties and filters you choose.
Stellar's base annual subscription fee is $550 for 2026, up from $525 in 2025. On top of that, your local REALTOR association adds its own Local Service Center fee, which varies by association.
That is separate from MLS Import, which is $49 a month after a 30-day free trial.
Most subscribers join through a REALTOR association, and that is the standard route.
A Thompson subscription exists for brokers, agents and appraisers who hold no REALTOR association membership anywhere in the country, though it comes with no REALTOR association benefits. MLS Import works with either path.
Agents join through their broker's REALTOR association, and the broker has to already be a Stellar participant.
Brokers join through one of Stellar's 19 associations, after which their licensed agents join too. Once membership and a feed credential are both in place, MLS Import connects to the feed.
Choose one of Stellar's two RESO Web API gateways, MLS Grid or Bridge API.
Complete the three-party agreement between the broker, the vendor and Stellar MLS, demonstrating a working application or requesting sample data. Approved credentials go straight into MLS Import for an hourly sync.
An IDX feed is licensed data you may publish on your own website. Reciprocal access lets Stellar subscribers search partner MLSs such as CRMLS and Bright MLS inside Matrix, view and share only.
Those listings never enter your IDX feed, so MLS Import has nothing to import from them.
Compensation fields were removed from the Stellar MLS system on August 6, 2024. A broker may still display compensation for their own brokerage's own listings on their own website, never for another brokerage's.
Because those fields no longer exist in the feed, MLS Import never surfaces them.
Yes. MLS Import is a standalone WordPress plugin that syncs a Stellar MLS feed hourly into native WordPress posts.
It works with any theme, with deeper native integration for WpResidence, WpEstate, Houzez and Real Homes, and it runs on the RESO Web API using your own approved credentials.
Membership and a Stellar MLS feed credential come from Stellar, not from us. Once you hold both, MLS Import handles the WordPress side. Departments, numbers and hours below are Stellar's own, from its support page.
