The GIS backend framework — build your own apps on it.
Supabase / Directus, but for GIS data. A headless spatial backend — data serving + AI, then user management and per-layer permissions on the roadmap — that gives your app teams just the right backend, then gets out of the way.
A backend built for the way you actually ship
Uncapped users
No intentional per-user caps. Serve your apps to as many people as you need — the pricing doesn't punish reach.
Install in minutes
A single, dependency-free binary. A GitHub pull or a double-click — no Portal, no web adaptor, no multi-machine project.
Highly available
Lightweight enough to replicate behind a load balancer for an HA pair — horizontal scale without a heavy deployment.
Sovereign / on-prem
Runs on your servers, your cloud, or a laptop. Your data — and, optionally, your AI model — never has to leave the building.
Headless — any framework
No portal, no imposed front-end. Build with React, MapLibre, the ArcGIS JS SDK, or anything that speaks the ArcGIS REST protocol.
AI-native
Ask is built in — plain-language querying, analytics and styling over your data, with a fully on-prem local-LLM option.
Serving and Ask are here today
Everything you can try right now — the ArcGIS-compatible serving engine and the AI assistant — is shipping and free to run. The full framework vision goes one step further.
Serve — available now
FeatureServer + Vector Tile services over the ArcGIS REST protocol.
Ask — available now
Natural-language querying, analytics and styling, with a local-LLM option.
Serve your data. Then talk to it.
Strata serves your spatial data over the ArcGIS REST protocol, then lets anyone explore it in plain language — on-prem and sovereign, at a fraction of Enterprise cost. Keep your Esri licenses.
