🧱 In-browser AI app builder

Zylo Code — describe it, watch it build.

You describe what you want; an Architect agent plans it, writes real files into a virtual file system, renders the result live, runs checks, pushes to GitHub and deploys — all in the browser, with no local toolchain.

Zylo Code live preview: Web / Diffs / Terminal / Files tabs with a generated landing page rendering live

The live preview (Sandpack) renders your app as it's written — with Web / Diffs / Terminal / Files tabs and click-to-edit.

How a build works

One agentic loop, driven by streaming tool calls.

1 · Plan

For a new app or a non-trivial change, the Architect emits an interactive plan card (summary, stack, ordered steps, files) and waits for your approval. Tiny edits skip the gate.

2 · Scaffold & build

It writes real files into a virtual file system; web apps preview live as they're written, character by character.

3 · Dispatch specialists

In Orchestrator mode it fans out up to 5 sub-agents (layout, styling, copy, QA, assets), then merges and reconciles.

4 · Test & ship

It always writes tests, emits a downloadable Walkthrough, pushes to GitHub, deploys, and suggests follow-ups.

Everything it can do

The Architect

An agentic loop that plans, asks when ambiguous, writes files, delegates, tests and ships — with auto-recovery that feeds preview errors back for an auto-fix.

Build modes

Plan (approval gate), Fast (write immediately), Orchestrator (5 specialists in parallel), Security (audit only) and Custom.

Live preview

An in-browser bundler (Sandpack) with Tailwind + shadcn tokens wired in; edit mode lets you click any element to target your next change.

Output panel

Web (preview), Files (the VFS tree), Terminal (build + a Fix button) and Security (findings). Diffs open from the Walkthrough.

1-click deploy

Publish the build to Vercel, Cloudflare, Netlify, Railway or Google Cloud Run with an OAuth/token connect.

GitHub

One-click OAuth (or a token); every build auto-saves to a repo, and the Architect can push and open pull requests.

Composer & “/btw”

Queue follow-ups mid-build, @-mention files and designs, and ask a read-only consultant (“/btw”) about the build without interrupting it.

Design tools & BYOK

UI/UX Pro Max, Motion and 21st.dev Magic + an ~88-component catalog; bring your own OpenAI-compatible provider (OpenRouter, Groq, Anthropic, Ollama…).

See it in action

Orchestrator mode: the Architect dispatches Layout, Styling, Copy and QA specialists in parallel

Orchestrator mode — the Architect reasons, plans, then fans out to specialists (Layout, Styling, Copy, QA) working in parallel.

Zylo Code home screen with starter templates and recent sessions

The home screen — start from a prompt or one of ~69 starter templates; folders group builds and map to a repo.

Zylo Code pushing to GitHub and deploying

Ship it — auto-save to GitHub, open a PR, and deploy to your host of choice.

Real use cases

💡 Prototype in an afternoon

From a one-line idea to a working React app with live preview, a GitHub repo and a live deployment — no local environment to set up.

🔒 Security pass before merge

Switch to Security mode and the Architect audits the project for vulnerabilities without adding features.

🏢 Build to your standards

Point Zylo Code at your own model (BYOK) and design system so generated apps match your stack and brand.

Frequently asked questions

Do I need to install anything?

No. Zylo Code runs entirely in the browser — the Architect writes real files, previews them with an in-browser bundler, and pushes to GitHub. There's no local toolchain.

Which models can it use?

Any Zylo model via your API key, plus BYOK: add any OpenAI-compatible provider (OpenRouter, Groq, Together, Anthropic, Google, Cerebras, a local Ollama, and more).

Where does my code go?

Every build links to a GitHub repo and auto-saves, so work is never lost. You can also give the Architect read-only context repos to build against.

Can it deploy for me?

Yes — one-click deploy to Vercel, Cloudflare, Netlify, Railway or Google Cloud Run.

Wanna try it?
