The Vantage framework # One engine. Six layers. Cut it open. Under Vantage UI runs a compiled Rust data engine. Scroll — each layer lifts away until you reach the query builder at the core. Every layer swaps. Layer 00 · Presentation ## Vantage UI Open an existing app with Vantage UI — or ask an AI agent to build a custom one from your data source using CRUD, forms and lists and dashboard. Forever free. Runs on macOS & Linux today; Windows builds are delivered for enterprise customers. Free Built into Vantage UI One-click download YAML + Rhai ## Vantage custom UI Need widgets the standard packaging doesn't ship — dashboards, specialised graphs, bespoke controls? We extend Vantage UI with custom UI elements built for your workflows. A dedicated build only your organisation runs — the same engine underneath, a richer surface on top. Built by our team Custom widgets Dedicated build ## UI & API adapters Swap the console for your own shell. `vantage-ui-adapters` embeds the engine into your UI framework; `api-adapters` exposes it as REST and live-streaming endpoints. A thin layer of hand-written Rust wires it up — the engine underneath stays identical. Requires Coding vantage-ui-adapters api-adapters ## React + your code Keep your frontend. Point React — or anything else — at the streaming API endpoints and consume the same typed, cached, reactive data. You own the UI code; Vantage owns the data path behind it. Requires Coding Your frontend Live endpoints Swap this layer Layer 01 · Reactive viewport ## Scenery A live viewport onto a fragment of your data. A Scenery subscribes and streams every change to the elements bound to it — sort, page and filter are part of the viewport itself. How data flows in is a Lens strategy. The on-device default just works. Built into Vantage UI Streams changes Virtualised paging ## Lens · API adapter Rehome the Lens onto your API tier: sceneries fetch through your own service, with pre-warmed caches tuned for a large number of active viewports. You implement the Lens transport in Rust; every scenery keeps the same contract. Requires Coding Server-side Lens Pre-warmed ## Lens · WebSocket Stream scenery diffs over WebSocket — the same reactive contract, pushed across the wire to remote clients in real time. Push, not poll: your Rust service forwards the diff stream; screens stay live everywhere. Requires Coding Live diffs Push, not poll Swap this layer Layer 02 · Local cache ## Diorama A high-performance local cache that keeps your working set close — reads come back in microseconds, refresh strategy is yours to script. Ships as an ephemeral memory + disk cache. When the network gets flaky, the screen above it never blanks. Built into Vantage UI Latency collapsed Memory + disk ## External cache Point the Diorama at a cache your infrastructure already runs — shared between instances, surviving restarts, warmed by your own pipelines. A custom integration written in Rust against the cache contract. Requires Coding Shared cache Survives restarts Swap this layer Layer 03 · Universal interface ## Vista One handle with the same read and write surface over every backend. SQL dialects, SurrealDB, MongoDB, REST and GraphQL APIs, AWS, CSV, CLI tools — the full list lives on the [features page](https://vantage-ui.com/features/). Vista is capability-aware: it exploits what your data server can do and compensates for what it can't. Built into Vantage UI 12+ backends Capability-aware ## Custom DataSource Anything can become a Vista. Implement the `DataSource` contract for your internal store, private queue or vendor API — and every layer above gains it instantly. This is exactly what our dedicated commercial builds add for partners. Requires Coding DataSource trait One handle Swap this layer Layer 04 · Business logic ## Entity Tables Business entities described declaratively through Vantage UI — columns, relations, computed expressions — in YAML and Rhai your coding agent is happy to write for you. Change a model without shipping a binary; it all lives in git next to everything else. Built into Vantage UI AI-written Declarative ## Custom entity models Promote entities to real Rust types — compile-time checked columns, relations and subqueries. Refactor a large codebase and the compiler walks every use with you. Built for type safety and robustness where it matters most. Requires Coding Typed columns Relations & subqueries Swap this layer Layer 05 · The core ## Query Builder A multi-dialect, composable query builder at the very bottom. One expression model that renders to SQL dialects, SurrealQL and more — nested, joined and aggregated without string glue. Scripted straight from Vantage UI in Rhai: joins, aggregates, drill-downs — no recompile. Built into Vantage UI Multi-dialect Composable ## Custom queries Go below the scripts: hand-craft queries in Rust, integrate stored procedures, or wrap a custom API as an expression — and every layer above can use it. The bedrock is open; this is where dedicated builds go deepest. Requires Coding Stored procedures Custom APIs Swap this layer ## We can assemble the right stack for your organisation You have selected custom components — we can assemble this stack for your organisation: | # | Layer | Component | Status [Discuss your stack with us](https://vantage-ui.com/solutions/enterprise/) Custom builds, training and support live on the [enterprise page](https://vantage-ui.com/solutions/enterprise/).
