v0 is brilliant at turning a prompt into a polished React component you can paste into your codebase. ArchStage starts one level up — it scopes the whole product, writes a tech spec, plans the sprint, and ships real code into a folder you control.
| Capability | ArchStage | v0 |
|---|---|---|
| Unit of work | Whole app, sprint-scoped | Single component / page |
| Code delivery | Real files in your folder | Copy-paste snippets |
| Sprint history | Persistent phase files | Per-generation chat |
| Tech spec / plan docs | Auto-generated per sprint | Not in scope |
| Mobile stacks | Kotlin + Material | Web only |
| AI provider | Anthropic Claude (Pro / Max / API) | Bundled in subscription |
| Desktop / offline | Desktop app, local-first | Web UI, cloud-based |
| Pricing | One-time €38 (launch) / €59 | Monthly subscription |
| Design output | Scaffolded, opinionated stacks | Polished one-off UI |
v0 shines when you already have a codebase and want a beautifully designed component to drop in. ArchStage is for when you're starting from nothing and want the whole scaffold — folder structure, stack choices, backlog, sprint pipeline — written for you.
ArchStage writes a tech spec, implementation plan, and phase-by-phase execution log for every sprint. You can reopen a project six months later and see exactly how it was built. v0's unit of work is a single prompt; context doesn't carry across generations the same way.
ArchStage ships React + Tailwind for the web, Kotlin + Material for Android, plus vanilla HTML and desktop tool scaffolds. If your next product isn't a Vercel-friendly React app, ArchStage still has you covered.
ArchStage users often use v0 alongside it — scaffold the product with ArchStage, then generate polished one-off screens with v0 and paste them in. The tools solve different layers of the same stack.
If you want one beautiful screen, reach for v0. If you want the whole app — with files in your folder and a sprint history that sticks — reach for ArchStage.
