Web and mobile
A TanStack Start web app and an Expo app share the API client, types and Tailwind config.
Stop shipping slop.Ship a real startup.
The SaaS starter that closes the agentic loop. Agents build, deploy and verify their own work.
One-time purchase. You get a private GitHub repository.
Connected to the services you'd pick anyway
WorkOS, Polar, PostHog, PlanetScale, Axiom and Sentry are configured in code and created on deploy.
Auth by WorkOS
WorkOS sessions work in the web app and the API.
Billing by Polar
Polar runs checkout and collects tax; refunds remove repository access.
Flags by PostHog
Flags live in a manifest in the repo and sync to PostHog on deploy.
Postgres by PlanetScale
Every developer, preview and agent gets its own database branch.
Telemetry in Axiom
A click in the browser and the SQL query it caused show up in the same trace.
Errors in Sentry
Sentry issues link to the trace that caused them.
Agents deploy their own copy of the app and check it
Each Claude Code or Codex session gets its own stage. The agent deploys to it, clicks through it in Playwright and reads Axiom and Sentry before it hands you a pull request.

Done. Deployed to agent-7, checkout tested. PR 143 is ready.
One deploy command, and a preview for every pull request
The infrastructure is TypeScript in the repository. Alchemy deploys it to your own AWS account.
Deploy with Alchemy
task deploy ships the database, API, web app, flags and telemetry.
Preview every change
Each pull request gets a backend, a web app, a database branch and a mobile build.
A Rust API with a generated TypeScript client
Change an endpoint and the client regenerates. SQL is checked against the schema when the API compiles.
struct Plan { tier: Tier, seats: u32, seats: u32,}
"Plan": { "tier": Tier, "seats": integer "seats": integer}
type Plan = { tier: Tier seats: number seats: number}
<Seats count={plan.seats} /><Seats count={plan.seats} /><Text>{plan.seats} seats</Text><Text>{plan.seats} seats</Text>sqlx::query!("SELECT plan FROM users WHERE id = $1", id)
// checked against the schema at compile timeif (isFailure(error, "plan_already_owned")) … // typed failures, straight from Rust

Questions
Something else? Email happyhack@kreos.company.
- What exactly do I get?
- A private GitHub repository with the full source: web and mobile apps, the Rust API, infrastructure and all 24 modules.
- Is it a subscription?
- No. You pay once, and Pro includes everything in Starter.
- Do I have to use AI?
- No. It is an ordinary codebase you can work in by hand. The agent rules, skills and per-agent stages are there if you use Claude Code or Codex, and you can delete them if you don't.
- What do I need to run it?
- Git, Task and Docker on your machine; mise installs the rest. You also need an AWS account and accounts with PlanetScale, WorkOS, Polar, PostHog, Axiom and Sentry. The setup guide covers each one.
