Astro is an AI app builder that works like a real engineering team. It runs your project through four stages (Requirements, Planning and Architecture, Design, Validation and Approval) with mandatory human approval before anything ships. Whether you're starting fresh or bringing an existing app in, the same process applies. Setup, provisioning, and deployment are fully automated.

Who is Astro built for?

Astro is built for semi-technical founders who want production-ready software. You can read code and evaluate architecture but you don't write code daily. You're either starting a new project the right way from day one, or hardening something you've already built without throwing it away.

What comes built into every Astro project?

Every Astro project starts on production-ready foundations: authentication with MFA and social login, role-based access control, Stripe billing and subscriptions, internationalization, web and mobile from one codebase, and the Sierra UI design system.

Astro is an AI app builder that works like a real engineering team.

From the first idea to the shipped app.

Most tools ship a demo. Astro ships a product.

Built by the team behind 50+ MVPs, 7+ exits, and $150M+ raised for founders.

The platform we wish we'd had for the last 50 MVPs.

Preview access rolls out in waves. Waitlist members get early updates and first invites.

Built for semi-technical founders. Day one through past v1.

AI can write code. It still skips engineering.

Whether you're starting fresh or hardening what you've built, the failure modes are the same.

Requirements stay fuzzy until something breaks.

Architecture gets guessed on the fly.

Asking AI to fix one bug introduces two others.

Context disappears between prompts.

The codebase you ship is the codebase you can't extend.

Every stage ends in something you can review before the next step begins.

From idea to a production app in 4 stages. Zero setup.You review and approve at every gate. Astro generates the work. Provisioning, CI/CD, and deployment are fully automated.

Requirements

Planning and Architecture

Design

Validation and Approval

Requirements

What's in, what's out, who it's for. Astro produces the spec. You review.

Planning and Architecture

Delivery sequencing, system design, integrations, security. Astro designs. You approve.

Design

Screen inventory, components, accessibility, Sierra theme. Astro produces a complete UI plan. You review.

Validation and Approval

Consistency checks. Final human sign-off before anything ships.

Validation and Approval

Consistency checks. Final human sign-off before anything ships.

Setup is on us.

When you approve, Astro provisions the repo, configures CI/CD, sets up environments, and prepares the deployment runbook. You don't lift a finger.

Greenfield

Start a new project. Astro decides architecture before generating a single line.

Recovery

Bring an existing codebase into Astro. Start from whichever gate fits.

Mandatory human approval before anything ships. Optional checkpoints between stages let you redirect early.

Each stage produces an artifact you can read, change, or reject before the next stage starts.

Built now, not just planned.

Astro is in preview. The Foundation is live today. Bring an existing app into Astro, or start fresh on top of it.

Astro is built by the team behind these numbers.

50+

MVPs we've shipped

$150M+

Raised by founders we built with

What exists today

Auth, MFA, and social login on day one

Role-based permissions so your whole team stays in control

Stripe billing and subscriptions ready to charge

Internationalization built in. Ship in any language.

Web and mobile from one codebase

Sierra UI, the complete design system, included

These are the things that usually break later. Astro ships them already wired.

The process model is explicit and reviewable, not a black box.

Join the waitlist for the platform that takes your app from first idea to production.

We're onboarding semi-technical founders in waves. Waitlist members get the first invites and product updates.

In preview now. Expanding in stages.

Lifecycle capabilities ship in focused phases. Stability before expansion.

In preview now

Requirements to plan, generated from your idea
Tasks that carry full context the AI can execute without losing the thread
Incremental code changes you can review in small batches

Coming next

Deployment and operations automation
Built-in QA and regression workflows
Implementation-time security checks

Roadmap principle: stability before expansion.

Roadmap direction reflects current priorities and may evolve with preview feedback.

Built for semi-technical founders who want production software the right way.

If you can read code, you can drive Astro. You stay in control. Astro carries the load.

Strong fit if you are

You can read code. You don't write it daily.
You're starting fresh, or you've already built something fragile.
You want production architecture before your first line of generated code.
You want engineering rigor without hiring a full team.
You want a codebase an engineer could inherit later without a full rebuild.

Not optimized for

Teams that want unlimited generation without review gates
Pure hobby projects with no plan to ship to real users
Engineering teams with dedicated architects already on staff
Projects that don't need to grow past v1

Common concerns, directly answered

Straight answers for teams evaluating whether Astro fits a real production workflow.

How is this different from other AI app builders?

Most tools optimize for first prompt to first demo. Astro optimizes for first idea to shipped product you can grow past 1,000 users. Same input. Different ceiling. Every stage produces a reviewable artifact you can approve, refine, or reject.

Do I need to write code to use Astro?

No. Astro generates production code on a structured pipeline. You review and approve at every stage: requirements, architecture, tasks, implementation. If you can read code well enough to know what an architecture decision means, you can drive Astro.

Will I be locked in?

No. Astro builds on standard JS/TS stacks (Expo and NestJS) on a real codebase you own. If you ever leave the platform, the code keeps working. No proprietary syntax, no DSL.

Can I bring an existing app into Astro?

Yes. Astro can pick up an existing codebase and run it through the same four stages, starting from whichever gate fits. You don't have to throw away the work you've done.

Is this available now or just roadmap?

Astro is in preview. The Foundation is live (auth, billing, MFA, RBAC, internationalization, web and mobile). Additional lifecycle capabilities ship in stages.

Join early. Build the app that ships to production.
