New Design gate — pick a look before the build

Build beautiful apps
from a single sentence.

Describe what you want. AppNGen plans the architecture, writes the code, tests it, and gives you a live preview.

Free to start · no card

Git-backed · tested · deployed — not a snippet generator.

An end-to-end pipeline Spec→ Architecture→ Coding agent→ Preview→ Deploy
How it works

Three steps, start to production

You stay in the conversation. The pipeline handles the rest.

1

Describe

Tell AppNGen your idea. A planning agent turns it into a concrete feature set.

2

Plan & build

The architect designs the system; a coding agent implements each sprint and gates it with tests.

3

Preview & ship

Every build gets a live preview backed by real git history. Iterate by chatting.

Capabilities

Everything between “what if” and “it’s live”

Architect that thinks

Designs the system, picks the stack, batches work into gated sprints.

Autonomous coding agent

Writes real files across a real repo, runs tests, and self-heals failing builds.

Live preview

Every build gets a real URL, backed by git history.

Design before you build

Lock in the look from generated concepts — it guides every line of code.

Git-backed history

Real commits, branches and diffs — export any time.

One-click deploy

Ship to a live domain when it’s ready — zero config.

Pricing

Design free. Pay for what you build.

Start on the free plan to design and preview a website. Paid plans include a monthly pool of build credits and unlock the full build-and-ship pipeline — pay only for what you use.
