The problem we’re trying to solve: today, people who want to build apps without coding often have to stitch together multiple tools, e.g. using Lovable for the frontend, n8n for workflows, and Supabase for the database. That creates data silos and leaves builders with fragile apps that break in production, don’t scale, and aren’t safe. We saw YouTube tutorials teaching people how to duct-tape these together just to get a functional app running. As engineers building no-code tools, we realized that people wanted the power of AI-generated UIs but also the ability to see and control their backend workflows and data.
Our solution is to generate the whole app at once, and represent it as a visual workflow. Users describe what they want in English (“I need a chat widget with an AI agent”) and VibeFlow generates both the interface and the logic. That logic shows up as a workflow graph they can edit visually or by giving new instructions.
We use Convex (https://www.convex.dev/) as backend. The generation of the backend code is fully deterministic, we map workflow graphs to code templates. This makes deployments predictable and avoids the hallucinated, black-box code you often get from AI.
Workflow representation: the logic is a directed graph where each node can be customized. We currently support CRUD operations and agent components. Any changes to the graph compiles directly back into code, so you always own the underlying logic.
Frontend: generated via AI and directly linked to workflow outputs, so it always stays in sync with the business logic. Changes to the frontend can be made through a chat interface.
Semi-technical builders can create maintainable apps (not opaque “magic”), and technical folks can still inspect the code and architecture. Compared to Bubble/Webflow, the interface is simpler; compared to Zapier, the workflows have an output code; and compared to AI coding assistants, you get an automatic backend plugged in with no black-box.
