Teams from the first sign-up
Every account gets a group at sign-up. Members, roles, invitations and ownership transfer work the same in every group.Try it in the demo (opens in a new tab)
Seed SaaS starter WIP
The groundwork every SaaS needs, already built.
Seed is the repository I start client MVPs from: teams, billing per member, realtime, an offline app and an admin area, on one server you own. Clone it and change it; it is MIT-licensed.
Website: seedsaas.com
Start a product from it
gh repo create my-product --template spy4x/seed --private --cloneThe next commands
cd my-product
cp infra/envs/.env.example infra/envs/.env
deno task vapid-key:create
deno task proxy:start
deno task devFill in the secrets in infra/envs/.env first. Then open http://app.localhost.

What an operator sees: the last 30 days at a glance, anyone found by name or address with their sessions and history, actions that ask first, every group and its members, who pays and every refund, and the health of every service. Sample data, 1 min, with captions and music.
The demo signs you in to the app with one click, as the demo user. Its data is made up, it takes no real e-mail address, and it is wiped every night at midnight Pacific time.
What you get
Realtime by default
People in a group see each other's changes live, over a WebSocket.Try it: open the demo in two windows (opens in a new tab)
Works offline
The app keeps the last notes and groups on the device and queues note writes. A stale write shows as a conflict for the person to settle.Try it: open the demo, then go offline (opens in a new tab)
Billing per member
Each group has one Stripe subscription, and its seats follow the member count.
Sign-in done properly
Passwords with a second factor from an authenticator app, sign-in with Google or GitHub, and a list of signed-in devices.Open the sign-in screen (opens in a new tab)
An admin area
It runs on a host of its own. Operators find a person, see their sessions, groups and audit trail, and can block them.
Where it stands
Works today
- Sign-up
- Sign-in with an authenticator-app code (TOTP)
- Groups with members, roles, invitations and ownership transfer
- Billing per member
- Notes, the reference aggregate
- The outbox worker
- The admin app
- The public website
- The SPA, which works offline
What is not built yet is on the open issues.
Use it if
- You are starting a SaaS where people share data in groups.
- You want to own the server and the code.
Skip it if
- You need a finished product today.
- You want a framework that updates under you: Seed is a starter you change.
- You deploy to serverless functions rather than a server you run.
The story behind it
- Seed: the SaaS starter I distilled from 80+ projects, and how I over-engineered v1
Why the first Seed failed, and what this one does differently.
- I tested Trail-code on my Claude Code agents. They ignored the map.
