The platform
Strata — serve your data, then talk to it
One platform, two capabilities. Serve publishes your data as ArcGIS-compatible FeatureServer + Vector Tile services. Ask lets anyone explore it in plain, natural language — with a fully on-prem, local-LLM option. A single, dependency-free binary you install in minutes.

The opposite of a multi-machine IT project
A GitHub pull or a double-click — no Portal, no web adaptor, no data store to stand up, no planning cycle. Run it on your laptop, then replicate behind a load balancer for high availability.
Single binary
Dependency-free. No database to run — DuckDB is embedded.
On-prem / sovereign
Your servers, your cloud, or a laptop. Your data never has to leave.
Highly available
Lightweight enough to replicate behind a load balancer for an HA pair.
Serve
Upload your data — it's a service
Upload a GeoJSON, Shapefile or CSV into the Strata Data Store and it's instantly an ArcGIS-compatible FeatureServer + Vector Tile service. Browse it like an ArcGIS services directory; ArcGIS Pro, the Maps SDK, QGIS and MapLibre connect unchanged.
Fully compatible with your ArcGIS Pro
1
ArcGIS REST compatible
FeatureServer + VectorTileServer endpoints, query, statistics, top-features, bins, generateRenderer, related records.
2
Cloud-native geospatial
Serve GeoParquet from local or cloud (S3) storage directly via DuckDB — no import step, no database to run.
3
ArcGIS Pro ready
Discoverable from Pro's “Add Server”, with the catalog handshake and folder-scoped services.
Ask
Then talk to it — in plain language
Ask turns plain-language questions into live maps, tables and charts over your data. A conversational assistant for everyone, a deterministic no-hallucination command mode for professionals, and a fully on-premises, local-LLM option so your data never leaves the building.

A scripted preview — the real product runs live on your ArcGIS services.
Natural language
Ask questions and give instructions in plain language; replies always match your language — Arabic included.
Deterministic commands
Composer commands run with no model in the loop — predictable, no-hallucination operations for pros.
Multi-agent reasoning
An orchestrator plans and delegates to specialists for query, analytics, geoprocessing, styling and charts.
Smart styling & labels
Class-breaks, unique-value, heatmaps, clustering, labels and popups — generated from a description.
Sovereign & private
Run fully on-premises with a local model (Ollama), or use a cloud model — your choice per deployment.
MCP integration
A built-in MCP server lets external AI assistants (e.g. Claude Desktop) drive the live map.

Honest boundaries
Serve is read-only today. Naming what Strata doesn't do is what makes where it wins believable to an Esri-savvy buyer.
Editing via REST (applyEdits) is planned for a later release, scoped to non-authoritative data collection — authoritative, versioned editing stays Esri's job.
—
No server-side editing or geoprocessing (yet)
—
No Portal / OAuth sharing model
—
No Image Server / GeoEvent
Strata is an independent, interoperable product. “Compatible with ArcGIS®” describes interoperability only.
