Repliers is an MLS data platform and search-portal API for developers, with an MCP server on top. OpenRealtor is the listing-agent workflow from walkthrough to listing prep, plus a ChatGPT and Claude connector for live listings, comps, and listing copy. The two products answer different jobs. OpenRealtor does not replace an MLS feed, and it is not a full MLS search-portal API.
On a listing team, OpenRealtor is complementary to the brokerage system you already run, including a platform such as Mainstay. It covers prep and the assistant. It does not stand in for that system, and it does not stand in for an MLS data feed.
Listing Pro is $199/month or $1,990.08/year, the same monthly price as Repliers Standard, for a different buyer. Repliers Standard is an MLS search-portal API for developers, on one board. Listing Pro is one listing-agent seat: walkthrough to listing prep, plus the OpenRealtor connector in ChatGPT or Claude. Listing Studio at $79/month ($790.08/year) is the agent-seat price under that $199 MLS API floor.

| Listing agentsOpenRealtor | DevelopersRepliers | |
|---|---|---|
| Who it is for | Listing agents and listing teams. The job is walkthrough to listing prep, then working the listing from the dashboard. | Developers building search portals on MLS data. Published plan copy describes a search portal with market analytics. |
| What you are buying | An agent workflow and a ChatGPT connector. Not an MLS board API, and not a full MLS search-portal API. | An MLS data platform and search-portal API, with an MCP server included on the published plans. |
| MLS data | Does not replace an MLS feed. Listing and comp answers are available through an OpenRealtor account. You still need your own MLS relationship for board access. | Preview is $0/month and sample data only, with no real MLS. Standard and above include real MLS data. The base plan is one MLS. Multi-MLS is an enterprise conversation. |
| ChatGPT MCP | Hosted connector at https://api.openrealtor.co/mcp. Ask about live listings and comps; saved searches and valuations you create through tools show up in the dashboard. One connector among others in the market, including Repliers. | MCP server on every published plan, including Preview. Hosted endpoint at https://mcp.repliers.io, plus an open-source server. Real MLS data still requires a licensed agent and MLS agreements. |
| Comps | Comparable sales for pricing a listing, in the product and through the connector. This is listing-prep comps, not a developer comps API over every board you license. | Comparables are included on the published plans. Preview returns them from sample data. |
| Listing copy and prep | Walkthrough video to floor plan, condition scores, and listing copy, then refine the wording in ChatGPT or Claude. | Not a listing-prep workflow. The published plans cover search, photo delivery, and market analytics for a portal. |
| Insights and Today | The Today view shows insight cards for price cuts and new listings in the agent's searches, plus daily picks. Those are the signals the product computes today. | Search Insights and market analytics for a portal. A different surface from an agent's daily prep view. |
| Saved searches and alerts | Saved searches live in the dashboard, including searches created through the connector, with email digests for the agent's own searches. | Not on Standard. Saved searches, favorites, and listing alerts are on Professional and Advanced. Preview's sample-data column marks saved searches and favorites as included, and listing alerts as not included. |
| Messaging | Assistant chat in the dashboard and in ChatGPT or Claude. That is the agent's own conversation, not a white-label messaging API for visitors on a search portal. | Not on Standard or Preview. Professional and Advanced include 2-way messaging, email, and text for the portal you build. |
| Natural language and image search | Ask in plain language in ChatGPT or Claude. OpenRealtor does not sell developer image search across an MLS photo corpus. Walkthrough photos are reviewed for the listing you are preparing. | On real-MLS plans, natural-language search starts at Professional. Image search, image classification, and quality scores start at Advanced. Standard includes none of those. Preview is sample data; its column marks natural-language search and image search as included. |
| Webhooks | Not sold as a developer webhook product. | On real-MLS plans, webhooks are on Advanced only. Standard and Professional do not include them. Preview's published column marks webhooks as included, still on sample data. |
| Price | Free $0/month. No annual commitment. Listing Studio $79/month or $790.08/year. One agent seat. 7-day trial. Listing Pro $199/month or $1,990.08/year. One agent seat, for higher volume. Buyer Team $599/month or $5,990.04/year. Concierge Buyer Team Pilot $500/seat/month. First 5 seats at $500/seat/month. Each additional seat at $700/month. Brokerage: Custom. Built around your organization. | Preview $0/month (sample data only). Standard $199/month. Professional $299/month. Advanced $399/month. No setup fee. Month-to-month. Annual payment is one month free. Add-ons are extra: archived data, AI estimates, geographic and parcel boundaries, public records, schools, and demographics. |

For listing agents, yes, in the sense that it is the other product people compare when they want an assistant on live listings. It is not a drop-in replacement. Repliers sells MLS data and a search-portal API to developers. OpenRealtor sells listing prep and a ChatGPT connector to listing agents. Many teams could use a brokerage platform, an MLS, and OpenRealtor at the same time.
No. OpenRealtor does not replace an MLS feed and is not a full MLS search-portal API. Repliers Standard at $199/month is the published floor for real MLS data on one board. OpenRealtor Listing Studio is the agent seat under that floor, and Listing Pro is $199/month for a different buyer.
