# Strata by Tabaqat

> Strata is the ArcGIS-compatible spatial platform. It serves your geospatial
> data as ArcGIS REST FeatureServer + VectorTileServer services (GeoParquet +
> DuckDB under the hood), and lets anyone explore it in plain natural language.
> Install in minutes as a single, dependency-free binary. On-prem and sovereign,
> with a local-LLM option. Keep your Esri licenses; add Strata for the rest.

## What Strata is
- ArcGIS Server / ArcGIS Enterprise alternative for the web-facing, read-only
  serving and data-exchange tier — a fraction of Enterprise cost.
- "Supabase / Directus for GIS": a headless spatial backend between ArcGIS
  Server and ArcGIS Portal. Serve + AI + (roadmap) user management & per-layer
  permissions. Uncapped users. Build your own apps on it.
- Serve GeoParquet as a FeatureServer / Vector Tile service; works unchanged
  with ArcGIS Pro, the ArcGIS Maps SDK, QGIS, and MapLibre.
- Ask: natural-language conversational GIS with a deterministic, no-hallucination
  command mode and a fully on-prem / local-LLM (Ollama) option.

## Pricing (public, USD/year)
- Free: $0 — single machine; capped layers/users; Ask included.
- Team: $1,200/yr — up to 200 layers and 200 users, one machine; Ask included.
  ~10% of ArcGIS Enterprise Standard on-prem US list price (~$12,241/yr).
- Unlimited: $2,400/yr — no limits, uncapped users, up to two machines (HA pair);
  Ask included. ~20% of ArcGIS Enterprise Standard on-prem US list price.
- Solutions: finished, industry-specific outcomes built on Strata — DIY free
  from the open template repo, or delivered + supported.

## Honest boundaries
- Serve is read-only today: no editing, server-side geoprocessing, Portal/OAuth,
  Image Server, or GeoEvent. Editing via REST applyEdits is planned for a later
  release. Strata coexists with Esri; it does not replace authoritative editing.
