React Drag-and-Drop Page Builder

Developers often look for a React drag-and-drop page builder to hand layout control to marketing without shipping code for every change. BYOB takes a different route: it generates a structured page from a prompt, then gives you visual reordering, and exports real source that you own.

Live workspace

Code, chat, and preview in one place.

The workspace is built for repeated product work, not disposable demos. Every generated file stays inspectable, every change is visible, and every follow-up can target the exact part of the app you care about.

01 · EDITOR

Generated code, ready to edit.

Every file BYOB writes stays visible and editable. Follow-ups target the exact lines you care about instead of regenerating from scratch.

Prompt to app

From first prompt to a workspace you can ship.

Start conversationally, approve the shape, let Tool Mode implement, then refine and deploy from the same workspace.

01 Describe the product Start with the outcome, audience, and any constraints. BYOB turns the idea into a practical build plan.
02 Shape the UX Review the proposed flows, screens, data needs, and visual direction before code starts moving.
03 Generate the app Tool Mode writes SvelteKit code, connects integrations, and keeps each change visible in preview.
04 Test and refine Ask for edits, roll back when needed, run checks, and keep the project editable instead of disposable.
05 Deploy Ship the finished app, connect domains, and keep iterating from the same workspace.

Agent and backend

Code with your agent, ship with a real backend.

Connect Codex, Claude Code, or Antigravity to your project, then store data and ship to production without leaving the workspace.

Built for shipping

The parts that usually slow you down are already here.

BYOB handles product planning, implementation, preview, testing, database work, and deployment from one focused interface, with coding-agent access and production analytics when you want to keep working from your own terminal.

This part is hands-on. The cards drift until you touch them. Drag to rearrange, or press and hold one to feel it push back.

Agent integrations

Give Codex, Claude Code, or Antigravity scoped access through BYOB CLI or Agent MCP. Your agent reads context, edits code, tests previews, and deploys from your terminal.

Git history and diffs

Every change lands as a commit. Inspect history, compare diffs, and see exactly what changed since the last deploy.

Inbox in every project

Every project ships with an inbox. Collect messages, leads, and feedback from your app without wiring a third party.

Email sending built in

Send magic links, OTP codes, and transactional mail from your own sender address. Resend-backed, no SMTP setup.

Google and magic-link login

Offer Continue with Google plus passwordless email codes. Sessions and callbacks are handled.

Custom domains and SSL

Point your domain at BYOB with guided DNS checks. Certificates are automatic.

Visual editing

Click any element in the live preview and describe the change. Copy, spacing, color, behavior.

AI testing agent

Run full-site or feature checks and get implementation-level feedback you can apply in one step.

Version rollback

Step between saved states or redeploy a known commit when an experiment goes sideways.

One-click deploy

Builds publish to production hosting in one step. Deploys can auto-save the project state first.

Deployment analytics

Worker traffic, errors, CPU timing, subrequests, and custom-domain status from the workspace.

Supabase aware

Connect Supabase and BYOB reads schemas, drafts migrations, and generates types that match your app.

Team collaboration

Invite people in and keep sessions coordinated so work never overwrites work.

BYOB is not a React drag-and-drop library; it is an AI builder that generates a SvelteKit site from a prompt and lets you rearrange sections visually. If you need a runtime builder embedded inside your own React app, use dnd-kit or react-dnd instead. If you need a finished page fast and editable, BYOB fits better.

Why teams want a React drag-and-drop builder

The appeal is control without redeploys. A marketing team wants to rearrange a hero, tweak a heading, or add a testimonial without filing a ticket and waiting for the next release. A React drag-and-drop builder promises that by treating page structure as data: the user drags a block, the underlying array changes, and React re-renders. It is a clean idea, and for content teams it is a genuine improvement over asking an engineer to edit JSX.

The hidden cost of building it yourself

Reality arrives when you implement it. You need a drag library such as dnd-kit or react-dnd, a nested tree of blocks with stable IDs, keyboard and touch support, drag previews, serialization for persistence, and a schema for each block type. Then come undo, validation, and server-side rendering concerns. What looked like a weekend project becomes an internal product, and its real cost is the maintenance of that editor, not the page it produces.

How BYOB avoids the editor problem

BYOB separates authoring from rendering. You describe the page, and the model returns sections as structured markup that the hosted site renders. To change order, you drag blocks in the visual editor, which edits the generated project rather than maintaining a drag library at runtime. There is no schema to design for a first draft, because the first draft already exists. The editor is the product, not something you have to build and then keep alive.

Output, honestly: SvelteKit not React

It is worth being precise. BYOB generates SvelteKit applications, not React components, so it is not a drop-in for a React codebase. If your constraint is that the builder must emit components into an existing React repo, this is the wrong tool. If your constraint is shipping a fast, editable site and owning the code, the framework is an implementation detail you can read, host, and modify. Choose on the constraint that actually matters.

When react-dnd or dnd-kit is the right answer

Reach for a React drag-and-drop library when end users build their own layouts inside your application: a dashboard builder, a form designer, a kanban board. Those need drag interactions at runtime, deep integration with your data model, and permissions. BYOB is an authoring tool for the site itself, not a component you embed to let customers rearrange their own dashboards. Matching the tool to the job prevents a painful rebuild later.

From prompt to owned source

Describe a launch page with a pricing table and two testimonials, generate it, then drag the proof section above the pricing block and publish. Edit copy inline, adjust the palette, preview on a phone, and export the project as a ZIP when you want to take it elsewhere. The workflow is aimed at getting a correct page live quickly, then iterating in the editor instead of in pull requests. For site marketing sites, that is usually the faster path than assembling drag-and-drop yourself.

FAQ

Frequently Asked Questions

Does BYOB generate React code?

No. It generates SvelteKit applications. The visual editor and generated output are framework-specific, so it is not a drop-in for a React repo.

Can I drag and drop sections?

Yes. Reorder generated sections visually, rewrite copy inline, and restyle blocks without touching code.

Can I export the source?

Yes. Export the project as a ZIP to host or extend it yourself.

Is this a runtime builder for my users?

No. BYOB authors the site; it is not an embedded component that lets your customers rearrange their own pages.

Which drag library should I use instead?

For embedded React drag-and-drop, dnd-kit and react-dnd are the common choices.
