Genero Arc (Application Runtime Connector) decouples your Genero business logic from its user interface, so a single BDL backend can power any modern frontend — web, mobile, or an AI agent.
Your business logic stays in Genero, untouched. The frontend is no longer Genero’s concern — it’s yours to design however you want.
Modernize or reimagine?
Modernize · Enterprise — Modernize within Genero — recompile to GBC, standard multi-device. You stay in Genero’s rendering. Genero Enterprise
Reimagine · Arc — A bespoke UI beyond Genero — any framework, designed freely — on the same, unchanged BDL backend. You are here.
Backend, connector, any frontend
Your app becomes a backend that any client can drive — through a single typed contract.
Your BDL app runs unchanged
Your existing Genero / I-4GL business logic keeps running exactly as it does today.
Arc exposes it as a typed contract
Genero Arc turns your app into a backend that any modern client can drive — no BDL change.
Your frontend drives it
A web UI, a native mobile app, or an AI agent talks to that contract — you design the experience.
Design the interface your users deserve
The same Genero backend drives whatever frontend you choose.
Web frameworks
Build in React, Vue, Svelte or Solid — a bespoke UI, designed freely.
Native mobile
Ship native iOS and Android on the same Genero backend.
AI agents
Give AI agents controlled access to a deployed app — via its contract (see below).
…and more surfaces on the roadmap.
Migrate one app, one screen at a time
Arc coexists with GBC — no big bang, no BDL rewrite. Choose the path that fits.
Faithful migration
Drop in the reference renderer for a working UI immediately — same UX, no custom work. Keep or retire GBC on your schedule.
Hybrid
Replace individual screens with custom UI and modernize incrementally, screen by screen.
Greenfield
Build a fully bespoke UI from scratch — your BDL app is simply the backend.
Let AI agents drive a live app — not your source code
Give AI agents controlled access to a deployed Genero application through Arc — the app’s typed contract, never its source code.
This is run-time AI — an agent driving a live app. It’s separate from Genero Intelligence, which is design-time AI that helps developers write code. Different moment, different object. See Genero Intelligence (design-time)
Reimagine your Genero app’s frontend.
Keep the backend that runs your business. Build the interface your users deserve.
Talk to an expertFrequently asked questions
Do I have to rewrite my BDL app?
No. Your Genero business logic stays untouched — Arc exposes your existing app to a new frontend without any BDL source change.
Can I keep using GBC?
Yes. Arc coexists with the Genero Browser Client — migrate one app, one screen at a time, on your own schedule.
Which frontends are supported?
Web frameworks — React, Vue, Svelte and Solid — plus native mobile (iOS and Android), and AI agents.
How is this different from Genero Intelligence?
Arc is run-time: an AI agent (or any frontend) drives a deployed app. Genero Intelligence is design-time: it helps developers write code. Different moment, different object.
Does Arc expose my source code to AI agents?
No. An agent works through the app’s typed contract — never its BDL source code.
Can I migrate gradually?
Yes. Choose faithful migration, a hybrid screen-by-screen approach, or a greenfield bespoke UI — at your own pace.
