Regrid specializes in nationwide parcel boundary data and GIS workflows. Realie provides parcel geometry as part of a wider public-records dataset that also carries ownership, assessment, tax, transaction, mortgage, lien, and zoning records — an agent-native API publishing ~20 ms average with agent-first MCP + CLI on self-serve keys. Regrid was not in our September 2026 latency benchmark — verify Regrid’s current coverage, latency, and terms with Regrid directly.
The distinction here is scope rather than quality. Regrid is known for parcel boundaries and the GIS tooling around them, and teams whose problem is fundamentally cartographic often start there. Realie treats the parcel as the join key for a broader record: the boundary matters, but so do the owner, the assessment, the tax position, the recorded documents, and the zoning. If your product is a map, boundary specialists are a natural fit. If your product needs to answer questions about the property as well as draw it, a combined record avoids stitching two vendors together on parcel IDs.

Where Realie goes deeper
Geometry and attributes through the same parcel ID
When boundary and assessor/recorder fields come from separate vendors you own the join — parcel identifier formats differ by county, splits and merges break references, and refresh cycles rarely align. Realie normalizes identifiers and refreshes geometry and attributes through the same pipeline.
Low-latency API for live lookups
Realie publishes ~20 ms average. Products that fetch property context during a user session benefit when the boundary is one field among many returned in a single call.
Agent-native parcel + attribute lookups
Realie is agent-native: self-serve API keys work across REST, CLI, and MCP. Onboard agents via `/agents`, `/agents.md`, and `llms.txt`. Docs Mintlify MCP vs app `/api/mcp` — see docs.realie.ai for which surface matches your IDE workflow.
Where Regrid goes deeper
Self-serve quotas and enterprise path
Self-serve monthly: 2,000 parcel records + 200,000 tiles/mo included. Overage $0.10/record Standard, $0.15/record Premium, $0.001/tile. Base monthly price behind login — see Regrid plans / verify. Enterprise for >10k records/mo — contact Regrid sales. Latency is not published — verify with regrid.
Parcel boundaries and GIS workflows
Regrid is widely used for nationwide parcel polygons and GIS-oriented tooling. Teams whose core deliverable is cartographic fidelity or deep integration with an existing GIS stack should evaluate Regrid’s current offerings directly.
County coverage for boundary-only use cases
If boundaries are genuinely all you need, a boundary specialist may be sufficient. Confirm polygon quality, update cadence, and identifier conventions in your target counties with Regrid.
When to choose Realie vs Regrid
| Scenario | Recommendation |
|---|---|
| Your product is a map and boundaries are the primary deliverable | Evaluate Regrid — verify GIS fit and county coverage with Regrid |
| You need owner, tax, transaction, and zoning fields alongside geometry | Realie — single record keyed on parcel ID |
| You want a free-tier pilot without stitching two vendors | Realie — production dataset on the free tier |
| Latency-sensitive property lookups in a live request path | Realie — ~20 ms average; verify Regrid from your infrastructure |
| Cursor or Claude Code agents need parcel + assessor fields via MCP | Realie — agent-first MCP + CLI; verify Regrid agent surfaces with Regrid |

FAQ
- Does Realie include parcel boundary geometry?
- Yes — parcel polygons are returned alongside the assessor record, joined on the parcel identifier.
- Can I use Realie purely for parcel boundaries?
- Yes, though you are paying for a dataset whose value is the combination. If boundaries are genuinely all you need, evaluate specialists too.
- How does Realie handle parcel splits and merges?
- Normalized identifiers are maintained alongside the raw county values so historical references can still be reconciled.
- What is the coverage?
- 180M+ addresses · nationwide U.S. county coverage
