# 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. ## Install (one command) Download page: https://tabaqat.net/platform#download - macOS / Linux: `curl -fsSL https://get.tabaqat.net/install.sh | sh` - macOS / Linux without curl: `wget -qO- https://get.tabaqat.net/install.sh | sh` - Windows (PowerShell): `irm https://get.tabaqat.net/install.ps1 | iex` - Homebrew (macOS + Linux): `brew install tabaqatdev/strata/strata-server` - Scoop (Windows): `scoop bucket add strata https://github.com/tabaqatdev/strata-server-release` then `scoop install strata-server` The installer detects your CPU architecture, downloads the matching bundle, verifies its SHA-256 against the release's published SHA256SUMS, installs to `~/.strata` (`%LOCALAPPDATA%\Strata` on Windows), puts a `strata` command on PATH, and starts the server on http://localhost:8765. Sign in with `admin` / `strata` and change it after first login. Platforms: Windows 10/11; macOS 12+ (Apple silicon and Intel); Linux with glibc 2.35+ (Ubuntu 22.04+, Debian 12+, RHEL 9+). x86-64 and ARM64. Upgrades preserve state: re-running an installer replaces only `app/`, keeping `app-config/` (users, tokens, signing key), `layers.toml` and `data/`. Signing: Windows builds are not code-signed yet, so a browser download shows a SmartScreen "unrecognised publisher" warning — installing via Scoop or the PowerShell command avoids that path. macOS installs via curl or Homebrew are never quarantined, because macOS only quarantines files written by a browser. Every release ships SHA256SUMS signed with Sigstore cosign. Uninstall: delete `~/.strata` (or `%LOCALAPPDATA%\Strata`) and the `strata` shim. Nothing is installed system-wide. ## 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. ## Solution categories Solutions are organized in two levels: the category, then the solutions under it. Each solution is anchored on a published standard or a named obligation. Sixteen categories, ordered private-sector first. Each category page lists its whole solution library; live solutions link to something that runs today, at https://tabaqat.net/solutions//. - Geodata Management — DCAT-US 1.1, DCAT-AP, OGC API - Features/Records, STAC, ISO 19115: https://tabaqat.net/solutions/geodata-management - GeoAI — deterministic command mode, on-prem/local-LLM, Model Context Protocol, STAC MLM: https://tabaqat.net/solutions/geoai - Financial Services — IFRS S2/ISSB, NGFS scenarios, Basel concentration, CRA/FFIEC: https://tabaqat.net/solutions/financial-services - Industry — CFIHOS 2.0, ISO 15926, ISO 55000, ISO 45001, PPDM 3.9: https://tabaqat.net/solutions/industry - Real Estate — RICS/IVS valuation, LADM Part 4, APA LBCS zoning: https://tabaqat.net/solutions/real-estate - Marketing — statistical geography, trade-area convention, Geopath OOH ratings, PDPL/GDPR: https://tabaqat.net/solutions/marketing - Energy — PHMSA 49 CFR 192/195, API RP 1173, PPDM 3.9, OSDU, Global Solar/Wind Atlas: https://tabaqat.net/solutions/energy - Telecom — FCC Broadband Data Collection, BSL Fabric, NTIA BEAD, USAC HUBB: https://tabaqat.net/solutions/telecom - Utilities — EPA LCRR/LCRI, SDWA, AWWA, EPANET, IEC 61970/61968 CIM, NERC FAC-003: https://tabaqat.net/solutions/utilities - Emergency Management and Response — FEMA NIMS/ICS, Community Lifelines, OASIS CAP 1.2, EDXL, NENA-STA-006, IRWIN/WFIGS: https://tabaqat.net/solutions/emergency-management - Local Government — Open311, APA LBCS, ISO 19152 LADM, address standards, 44 CFR 201: https://tabaqat.net/solutions/local-government - Transportation — FHWA HPMS, ARNOLD LRS, MIRE FDE, MAP-21 TAMP, GTFS, WZDx v4, IHO S-100: https://tabaqat.net/solutions/transportation - Health — CDC/ATSDR SVI, HRSA HPSA/MUA, WHO SARA: https://tabaqat.net/solutions/health - Education — NCES EDGE, NCES CCD, DataCite DOI: https://tabaqat.net/solutions/education - Environment — TNFD LEAP, SBTN, CSRD/ESRS, Copernicus, STAC, WDPA/IUCN: https://tabaqat.net/solutions/environment - Hydrology — FEMA NFHL, NFIP/CRS, OGC WaterML 2.0, IHO S-44: https://tabaqat.net/solutions/hydrology ## Honest boundaries - Solutions marked "Soon" on a category page are not shipping yet and are never sold as available. Only solutions linked to a running app are live today. - 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. ## Links - Platform: https://tabaqat.net/platform - Solutions: https://tabaqat.net/solutions - Pricing: https://tabaqat.net/pricing - Docs / GitHub: https://tabaqat.net/platform#docs - Contact: info@tabaqat.net
