Description
Everyone's shipping AI tools right now, and here I am with a visual editor. Still, I think many teams are very familiar with the problem of "marketing wants to change the landing page again."I've run into this for years. Campaign pages come in, engineers get pulled in, and tickets stack up. It's usually the same components, just rearranged.A few years ago, at a startup I worked at, we built an internal tool to deal with this. You register your existing React components, they show up as drag-and-drop blocks, and the result is a JSX string. No schema to learn, no changes to your component code.We used it in production, handling real traffic in a messy, legacy-heavy environment. It held up well. Over time, it powered roughly 60% of our traffic. Marketing shipped pages without filing tickets, and product teams ran layout-level A/B tests. That experience eventually led me to clean it up and open-source it.Composify sits somewhere between a no-code page builder and a headless CMS. Page builders like Wix or Squarespace offer drag-and-drop, but lock you into their components. There are also solid tools like Builder.io, Puck, and Storyblok, but many require you to adapt your components to their model. Composify is intentionally minimal: it lets you use your actual production components as they are.It's still early. The docs need work, and there are rough edges. But it's running in production and has solved a real problem for us. If you already have a component library and want non-devs to compose pages from it, it might be useful.Homepage: https://composify.js.orgHappy to answer questions or hear feedback!

Could you build this?
Partial Basic visual component builders are vibe-codeable, but creating a resilient Server-Driven UI (SDUI) system with schema validation, AST sync, and sandboxed live React execution requires deep frontend architecture.
What it would actually take: The platform requires a visual drag-and-drop editor that synchronizes a strict JSON component-tree schema with real React components, coupled with an SDK for server-driven UI hydration. The primary difficulty is bidirectional syncing between code ASTs and visual nodes, managing complex prop schemas, and safely executing dynamic layouts without breaking SSR or bundle performance. It requires senior React framework and compiler/AST tooling experience.

Same idea, different domain
Nobody's really built a dev tools tool for Sales yet.
