Of the real estate software developers we could check, Inoxoft scores highest, 9 out of 12, because it names a client whose listing site is live, describes IDX and map search in that case study, and has 74 Clutch reviews averaging 5.0. Glorium Technologies is second with 8, and Codica third with 7. Codica’s Tokkatok marketplace was the clearest live portal we found.
We wrote this guide, so weigh that. We left ourselves out of the ranking. Where we fit is in a box at the end.
Who this is for: brokerages, property managers, and proptech founders hiring a team to build a listing portal, an agent tool, or MLS feed work. Who should look elsewhere: if you’re one agent who needs listings on a website, you don’t need a development company. An IDX plugin costs less, and our IDX vs RESO Web API guide compares them.
Why another list
We read the pages that rank for “real estate software development company” on 2026-10-14. The top lists come from agencies that put themselves first:
- Modall’s list ranks Modall first and says so.
- Hicron’s list ranks Hicron first, with no scoring method.
- Wildnet Edge’s list ranks Wildnet Edge first and names seven factors with no scores.
None of them links a live portal a vendor built, gives vendor prices, or checks feed work. This list does those three things, and links every fact to the page it came from.
How we scored them
Six criteria, 0 to 2 points each, 12 in total. We counted only what the firm’s own site or Clutch shows. A firm may do more than it publishes. We can’t see that, and neither can you before you ask.
| Criterion | 2 points | 1 point | 0 points |
|---|---|---|---|
| Live portal | Names a client listing portal, and the site loads today | Names a client or its own product, with no live site we could open | None found |
| Feed work | A case study says the build included an MLS, IDX, or RESO feed | The site claims MLS or IDX integration, with no case study | Not found |
| Search and maps | A case study shows filtered search or map search | The site claims it, with no case study | Not found |
| Published price | A price or range on the firm’s own site | A minimum project size on Clutch | None |
| Code ownership | Says the code and IP are yours | Says your data is yours, or vague handover wording | Not found |
| Independent reviews | 15 or more Clutch reviews averaging 4.5+ | Fewer, a lower average, or marketplace reviews | None found |
Ties go to the firm with more live-portal points, then more Clutch reviews. To be listed, a firm needed real estate work on its own site that our page fetcher could read. All facts were checked on 2026-10-14. A live site shows the client still runs a portal. It can’t show whether today’s code is still the vendor’s.

The 7 companies
1. Inoxoft
- Live portal: its property management case study names Marketplace Homes, “a USA - based real estate company with more than 20 years of experience.” marketplacehomes.com loads and lists homes to buy and rent.
- Feed work: the case study describes “A user-convenient web platform with IDX functionality,” with an “IDX filter” as its first feature. Its MLS page says it “connects your platform to RETS, RESO Web API, IDX, third-party portals, and any internal system you already run.”
- Search and maps: users filter “(e.g. price, sqft, bedrooms, area, etc.)” “or to view available properties on the map.”
- Price: none on its site. Clutch lists $25,000+ and $25 to $49 an hour.
- Code: not found on the pages we read.
- Reviews: 5.0 from 74 reviews on Clutch.
- Watch for: the case study took “6 months” with a team of “8” on PHP 7 and jQuery, so ask what stack they’d use today. Inoxoft also publishes its own list of MLS developers, which ranks itself first.
- Best for: MLS and IDX-heavy builds where a long review record matters.
2. Glorium Technologies
- Live portal: its case study names “Liberkeys.” liberkeys.com loads, a French agency with a property search portal. The case study lists the client country as the United States, which doesn’t match.
- Feed work: the case study doesn’t mention MLS. Its real estate guide talks about “Connecting your software to MLS (Multiple Listing Service) databases.”
- Search and maps: the case study lists “A mapping system” and “Detailed search and filter criteria.” The work was mainly a new interface: “Combined new UI with the existing back-end.”
- Price: none for its own work. The guide says “a basic real estate application typically falls in the $40,000 to $80,000 range.” Clutch lists $25,000+ and $50 to $99 an hour.
- Code: not found.
- Reviews: 4.8 from 29 reviews on Clutch.
- Where: Houston, Texas, per Clutch.
- Best for: redesigning the front end of a portal that already has a working back end.
3. Codica
- Live portal: its case study covers Tokkatok, a “Real Estate Marketplace for the Philippines,” built “November 2024 - March 2025.” tokkatok.com loads, with search by rent, buy, city, and property type.
- Feed work: none. Owners and agents post listings through a form, with no MLS feed. That’s normal outside the US.
- Search and maps: “an Elasticsearch-powered search engine with faceted filters, price ranges,” “category-specific attributes, and location-based proximity search,” and “map-based location selection with address validation.”
- Price: none on its site. Clutch lists $25,000+ and $25 to $49 an hour.
- Code: not found.
- Reviews: 4.7 from 17 reviews on Clutch.
- Where: Tallinn, Estonia.
- Best for: marketplaces where owners and agents post their own listings. Ask for US MLS experience if you need it.
4. Ascendix
- Live portal: its map search case study is about Ascendix’s own product: “At Ascendix, we decided to build an effective marketing and sales tool.” No client portal URL. Its portal page says “Trusted by JLL, Calson, and Savills.”
- Feed work: the portal page says it can “integrate your real estate portal with MLS systems and other property portals.” No case study.
- Search and maps: the case study shows map search where users “draw custom shapes to narrow down specific location availabilities.”
- Price: none on its site. Clutch lists $5,000+ and $50 to $99 an hour.
- Code: not found.
- Reviews: 4.9 from 16 reviews on Clutch.
- Where: Dallas, Texas.
- Also: Ascendix shows up on more of the other lists than any firm we checked, including Modall’s and Wildnet Edge’s.
- Best for: commercial real estate, where its own products and its JLL and Savills work sit.
5. Wildnet Edge
- Live portal: none found. The case studies on its real estate page are for a wealth management firm.
- Feed work: “We build custom integrations with MLS listings, ERP and CRM platforms.” No case study.
- Search and maps: “Dynamic portals with advanced filters, media uploads, geo-mapping, and SEO.” No case study.
- Price: none on its site. Clutch lists $1,000+ and under $25 an hour, the lowest here.
- Code: the clearest statement on this list: “You get full ownership of the source code, IP, and data.”
- Reviews: 4.8 from 18 reviews on Clutch.
- Where: Noida, India.
- Best for: buyers who want IP terms in writing and a low hourly rate. Ask for a real estate portal it built before you sign.
6. Real Estate Webmasters
This is a real estate website platform you subscribe to. It also builds custom board integrations. We include it because it shows up for this search and publishes prices.
- Live portal: its home page shows client sites such as Realty Austin, by name and screenshot, with no links.
- Feed work: “We integrate with boards across North America and handle the data feed, compliance and attribution requirements for each one.” And: “If your board is not already connected, our team scopes and builds the integration.”
- Search and maps: not described on the pages we read.
- Price: pricing lists Single User $350, Small Team $499, and Large Team $799+, each with an IDX feed included (vendor pricing, checked 2026-10-14). The page sells extra users “per month” but doesn’t print the billing period for the plans.
- Code: it covers your data only: “Your content, your leads, your database.” And: “If you ever leave, you take your data with you.”
- Reviews: 4.5 from 1 review on Clutch.
- Where: Nanaimo, Canada.
- Best for: brokerages that want a ready MLS-connected site and don’t need to own the code.
7. Chetu
- Live portal: none. The real estate page names no clients. Testimonials are signed with first names and initials.
- Feed work: it lists “IDX/MLS systems, RETS/RESO web APIs.” The same page also calls RETS “real estate transaction software,” but RETS is the Real Estate Transaction Standard, the data protocol RESO has retired.
- Search and maps: not described.
- Price: none on its site. Clutch lists $10,000+.
- Code: not found.
- Reviews: 4.3 from 82 reviews on Clutch, the most reviews here, but the lowest average.
- Where: Sunrise, Florida.
- Best for: large buyers who want a big vendor and will run their own vetting.
Checked and left off
- SolGuruz and Agent Image blocked our page fetcher on 2026-10-14, so we couldn’t read their own sites. We don’t list facts we couldn’t read.
- Modall and Hicron Software each rank themselves first on their own lists, but we found no real estate portal case study on their sites.
- ScienceSoft’s real estate page returned a 404 when we checked.
If you build real estate portals and publish your work, send us the links and we’ll score you by the same rules.
What the scores say
- Live portals are rare. Only three firms name a client whose listing site we could open. Every list we read skipped this check.
- Nobody shows a full RESO Web API build. Several firms claim MLS or RESO work on service pages. None has a case study that walks through the feed. Ask for one, and read our IDX vs RESO Web API guide first so you know what to ask.
- Code ownership is the biggest gap. Only Wildnet Edge says the code is yours. Our guide to who owns the code when you hire an agency explains what to put in the contract.
Before you sign, run through how to vet an offshore development team before you send money, and check whether you need a portal at all in what a real estate portal needs that a WordPress theme can’t do.
Where Dawloom fits
We have no public real estate client, so we can’t show a live portal we built. Our live client work is FurnitureAxis, a retail platform with a scheduled catalog sync and Algolia search. That is the same shape of work as a listing feed, but it isn’t real estate. Our real estate page lists “Portal and MLS feed ingestion and syndication” and “Listing platforms with search and map views.” We have no real estate case study for either yet.
We bill $30 an hour, or by milestone, from a written scope (pricing). We don’t publish a project price. The code is yours: “The repository, the hosting account, the domain, and the documentation get set up under your name while we build” (how projects run). We have no Clutch profile. Our reviews are 4.9 from 343 on Fiverr and 5.0 from 156 on Freelancer.com, under our founder’s name, mostly for smaller jobs than a portal.
Pick someone else if you need a team that has already shipped a US MLS portal (Inoxoft), a live marketplace to look at first (Codica), or a ready site with a monthly price (Real Estate Webmasters). We fit when you want milestone billing and full code ownership for a feed sync or portal, and you’re fine being an early real estate client. If that’s you, tell us what you’re building.
FAQ
What does a real estate software development company build?
Listing portals with search and maps, MLS and IDX feed syncs, agent CRMs and lead routing, property management tools, and mobile apps for agents. The firms here range from a subscription website platform (Real Estate Webmasters) to custom build shops.
How do I check a real estate developer’s portfolio?
Ask for the name of a client portal, then open it yourself. Check that the listings load, that filters and the map work, and ask the client whether the vendor still maintains it. Only three of the seven firms here name a live client portal we could open.
How much does a real estate portal cost to build?
Vendor estimates vary widely. Glorium’s guide says “a basic real estate application typically falls in the $40,000 to $80,000 range,” and its Clutch minimum is $25,000. On top of the build, you pay monthly for the MLS feed, maps, search, and hosting.
Do I need MLS access to build a real estate portal?
Only if you want to show other brokers’ listings in the US. You then need a license from each MLS, and you must follow its IDX or VOW display rules. A marketplace where owners post their own listings, like Codica’s Tokkatok, doesn’t need MLS access.
