to a shipped product.

« J'adore votre app : elle est vraiment GÉNIALE et super pratique pour construire un projet de A à Z avec Claude. Je l'utilise principalement pour développer des packages R et Python pour les biostatistiques en écologie forestière et écologie aquatique. »

English "I love your app — it's genuinely amazing and super practical for building a project end-to-end with Claude. I mostly use it to develop R and Python packages for biostatistics in forest and aquatic ecology."

Biostatistics researcher · Building R & Python packages with ArchStage

If you've never written a line of code, you don't have to start now. Describe your idea in plain English, watch a real app take shape on screen, and change anything just by asking.

If you've shipped software before, nothing is hidden from you. Review the spec, shape the plan, jump into the code whenever you like, and ship on your own terms.

ArchStage meets you where you are, and takes you further.

How it works

From a sentence to something you can ship.

Five stages. You stay in charge at every one.

  1. Stage 01

    Describe what you want.

    A short conversation, not a spec. ArchStage asks a few plain questions — what kind of thing, who it's for, what matters most — and picks the stack for you.

    Wizard · 4 or 5 questions · plain English
  2. Stage 02

    Watch it draw what you described.

    A clickable sketch appears side-by-side with your chat. Ask for changes in plain English — swap colors, rewrite copy, move things around — until it feels right.

    Live preview · desktop · tablet · mobile
  3. Stage 03

    Plan what's next.

    Your project has a simple list: done, building now, up next. Not sure what to add? ArchStage suggests three ideas every time you ask — so you're never stuck staring at a blank backlog.

    Overview · add features as you go
  4. Stage 04

    Build it. Watch it ship.

    Press Build. ArchStage writes the code step by step and shows you every stage as it happens — with a clear progress ring, time estimate, and full pause-and-resume control.

    Pipeline · five stages · real code in your folder
  5. Stage 05

    Ship it. Run it. Share it.

    When the code is ready, ArchStage offers a handful of ready-made actions — open it, zip it, publish it. One click each, and you can always type your own.

    Launchpad · one click · no terminal
Showcase

Real products, built in real sprints.

Two projects, two stacks, two audiences. Each one started as a sentence.

Luxury Boutique prototype — Maison Éclat
Web App React · Tailwind

Maison Éclat — a luxury e-commerce storefront

Editorial hero, curated product grid, cart drawer, and a three-step checkout with animated order confirmation. Dark/gold palette, serif typography, ready to deploy.

Brief → Ship One afternoon
Peak Weather mobile Android app sketch
Mobile Kotlin · Material · Firebase

Peak Weather — a weather app for people who go outside

Animated gradient skies, four saved locations, activity readiness badges (run, cycle, hike), hour-by-hour forecast. Built for Android, shipped as a working APK.

Brief → Ship One afternoon
Who it's for

Whoever you are, wherever you start.

ArchStage speaks four dialects. It sounds like your work no matter which one you speak.

01 · Founders

Founders & solopreneurs

Turn a pitch into a working MVP before you write a single ticket. Show the product in the room instead of describing it around it.

"I have an idea I can barely stop talking about."
02 · Designers & PMs

Designers & product teams

Stop handing over Figma files that misrepresent reality. Ship prototypes that actually run — then iterate with the people who'll use them.

"I need to test this flow by Thursday."
03 · Developers

Developers who use Claude

Structure around Claude Code without writing specs by hand or managing context between sessions. Sprints, phase files, CLAUDE.md auto-update — still here, better organized.

"I want Claude Code on rails, not leashed."
04 · First-timers

First-time builders

No terminal. No stack to choose. No npm install anxiety. Describe what you want, see it take shape, refine it until it's yours. We handle the scaffolding.

"I've tried to learn to code three times."
What's inside

Everything the work needs. Nothing it doesn't.

Guided wizard

Four questions about aesthetic, audience, and must-have feature. No more staring at an empty prompt box.

Live visual sketches

A rendered prototype, not a wireframe. Desktop, tablet, and mobile previews update as you iterate.

Plain-English pipeline

Overview, Sketch, What's next, Fix something, Ship it. The machinery is still there — it just stopped shouting its job title.

Your stack, your code

React, Tailwind, Kotlin, Material, Firebase, vanilla HTML — pick a stack or let ArchStage pick one. Real code lands in your folder.

Configurable for power users

Sprint Skills, model selection per step (Haiku, Sonnet, Opus), editable system prompts. Invisible unless you want it.

Self-contained projects

One .archstg file. Portable, version-able, back-up-able. No cloud lock-in. No account to manage.

Local-first, quiet by default

No analytics. No telemetry. No cloud backend. Network calls go to Anthropic and to license validation. Nothing else leaves your machine.

Multilingual UI

The app ships in several languages, with more on the way. Describe your product in the language you think in.

Dark & cream themes

Two fully-realized palettes. Switch at any time. Your preference sticks.

Pricing

One price. Yours to keep.

No subscription. No seats. No usage markup. You pay Anthropic for Claude usage directly — we don't sit in the middle.

ArchStage requires an Anthropic account for Claude usage. You control your own plan and costs directly with Anthropic — Claude Pro, Max, or API all work. Most projects use $2–8 of Claude credits per sprint, billed by Anthropic.

Frequently asked

The details.

Do I need to know how to code?
No. You describe what you want to build and ArchStage handles the implementation. Some familiarity helps — knowing what "install dependencies" means will make the experience smoother — but you won't write code yourself. The built-in chat lets you run, test, and debug your project in plain English.
What kinds of apps can I build?
Web apps (React, Tailwind, vanilla HTML), mobile apps (Kotlin/Android, Material Design), desktop tools, internal tools, landing pages, e-commerce, dashboards. If Claude can write code for it, ArchStage can scaffold and ship it. Today's strongest stacks are React + Tailwind for the web and Kotlin + Material for Android.
What happens to the code — is it locked to ArchStage?
No lock-in. Real code, real files, in a real folder you own. You can open it in any editor, push it to GitHub, deploy it wherever you like. ArchStage is a workflow tool, not a hosting platform.
Does the terminal-friendly flow still work?
Yes. The sprint pipeline, tech spec / implementation plan / phase splitter agents, Sprint Skills config, model selection per step, and CLAUDE.md auto-update are all still here — they just live under Configuration now instead of being the main navigation. The guided wizard is the new front door, not a replacement.
How is this different from Lovable, v0, or Bolt?
Those tools generate a prototype and host it. ArchStage scaffolds a proper codebase in your stack, in your folder, on your machine, with a persistent sprint history and a proper architecture. The prototype is the starting point, not the product. And you keep the files. Full comparisons: vs Lovable · vs v0.
How is this different from Claude Code alone or Cursor?
Claude Code is a brilliant per-task assistant. ArchStage is the layer above it — sprints, phase files, persistent context, and a spec-driven execution model that works the same way every time. It's the difference between knowing how to cook and having a recipe. You can absolutely cook without one. See the full ArchStage vs Cursor comparison.
Do I need an Anthropic subscription?
Yes. ArchStage uses Claude for everything — sketching, planning, executing phases. You bring a Claude plan (Pro, Max, or API) and pay Anthropic directly. ArchStage has no visibility into or markup on your usage.
Where does my data go?
Nowhere it shouldn't. Everything is stored locally in a .archstg file. No cloud backend, no analytics, no telemetry. The only network calls are to Anthropic (for Claude) and our license-validation endpoint when you activate a purchase.
Mac, Windows, Linux?
Mac (arm64 + x64) and Windows today. Linux is on the roadmap — email us if you want to be notified.
What if I find a bug or need help?
support@archstage.app reaches the developer directly. No ticket queue, no support tier.
