The change wave

One prompt moves through your whole architecture.

Evonx maps your codebase into a live graph — repositories, modules, services, APIs — then routes every change through it as a single, reviewable wave.

01 — Describe

Say it in plain language

A brand-new app or a change to the systems you already run. No specs, no sprints, no hand-offs.

02 — Watch

It builds in front of you

Evonx plans the work, writes production-grade code, and spins up a live preview you can click through.

03 — Ship

Own every line

Every change lands as a clean pull request in your codebase. Review it, revert it, build on it — it's yours.

FAQ

Common questions about Evonx

What is Evonx?

Evonx is an AI-native platform for building and evolving software. Connect an existing repository or describe a new product; Evonx implements changes in your codebase, runs them in a live preview, and ships them as pull requests you review and own.

Can Evonx work with code I already have?

Yes. Evonx connects to your repositories, reads the codebase, and implements changes inside your project — migrations, APIs, and UI included. You keep the repo, the history, and the ability to hand it to any engineering team.

How is this different from a traditional dev agency?

There is no fixed project quote or hand-off document. You describe the change in chat, see it running in preview within minutes, and receive a real pull request. Iteration happens in the product, not across email threads.

Is there a free plan?

Yes. The Starter plan is free: connect a codebase, open your first Evolution Thread, and preview the result without a credit card. Paid plans add higher AI usage, more workspaces, and parallel previews.

What kinds of software can I build with Evonx?

Teams use Evonx for business applications — bookkeeping, invoicing, inventory, CRM, service desks — and for evolving existing web apps and Shopify themes. Each build uses production-grade patterns: typed code, real databases, and migrations.

Do I own the code Evonx generates?

Yes. Everything ships into repositories you control. Evonx uses standard, portable stacks so your team can maintain, extend, or migrate the software without platform lock-in.
