AI Fusion Builder Alternative
Fusion Builder ships inside the Avada WordPress theme, which means a theme licence and a WordPress site before you can drag a single element. BYOB OnePage takes a different route: describe the page and let the AI lay it out.

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.

Loved by builders
Rated 4.9/5 by developers and founders using BYOB to move from idea to shipped product.
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 OnePage is an AI alternative to Fusion Builder for sites. Instead of dragging Avada elements inside WordPress, you describe the page and receive a structured layout with hero, features, pricing, and FAQ sections that you refine visually, with no theme licence, plugin stack, or publishing to maintain.
Why people look for a Fusion Builder alternative
Fusion Builder is capable but tightly coupled: it comes with the Avada theme, runs only inside WordPress, and adds weight through its shortcode and asset layers. People search for an alternative when they want a single landing page without standing up a whole CMS, when theme licence renewals stop making sense, or when they would rather describe the page than assemble it from containers. BYOB OnePage targets exactly that narrower job.
From element stacking to a single prompt
In Fusion Builder you place containers, columns, and elements, then style each one. In BYOB OnePage you write a sentence such as a launch page for a coffee subscription with three plans and a signup form, and the sections arrive populated. That first draft is the starting point, not the finish line: reorder blocks, rewrite copy inline, and change the palette. For a focused siter, generating the skeleton removes the slowest part of the work.
What you give up, and what you gain
You give up Fusion's deep WordPress integration: no dynamic content from posts, no WooCommerce product loops, and no Avada-specific add-ons. In exchange you get a page that loads without a theme framework, needs no security patches, and can be edited by someone who has never opened wp-admin. For a marketing page, an event, or a services overview, that trade is usually the right one. For a content-heavy WooCommerce store, it is not.
Moving your copy out of Avada
There is no automatic Avada-to-BYOB converter, so plan on a content migration rather than an import. Copy your headings, body text, and calls to action from the WordPress editor, gather your images, then paste the text into BYOB and let the assistant rebuild the structure. Because the AI works from your real words, the result keeps your message while shedding the shortcodes and nested containers that made the original hard to maintain.
When a full site beats a siter
Fusion Builder and Avada are often used for entire sites, and a site generator is a powerful starting point. When you need a blog, user accounts, or data storage, BYOB's full app builder extends the project into a multi-page application with login, data, and publishing, while the original page stays as the landing that fronts it. Use each for what it does best instead of stretching one tool.
FAQ
Frequently Asked Questions
Is BYOB a drop-in replacement for Fusion Builder?
Only for sites. It generates and hosts that page without WordPress. If you depend on Avada's full site-building and WooCommerce features, keep them for those projects.
Can I import an Avada layout?
There is no automatic importer. Copy your text and images, then regenerate the layout, which the AI rebuilds around your existing copy.
Do I need the Avada theme to use BYOB?
No. BYOB is independent of WordPress and Avada; nothing needs to be installed or licensed first.
Will the page be fast?
Pages are generated as compiled, responsive markup rather than a theme framework, which keeps the shipped code lighter to start.
Can I use my own domain?
Yes. Publish free on a BYOB address, then connect a custom domain from a paid plan.
