Secure before you think about it

The safe setting is the only starting point.

No database key reaches the browser
Tables stay private until you open them
Every deploy is scanned for leaked keys

// flatstack/schema.ts
export const recipes = table("recipes", {
  id: text().primaryKey(),
  userId: owner(),
  title: text().notNull(),
});
// Only the owner can read or change a row.

For people who start a lot of projects

Park the ones you aren’t using, so they don’t take a full slot.

Park it: It stays live on its own address at small limits, and it’s never paused. Parked slots: 10 on Hobby, 50 on Pro and 100 on Studio.
Promote it: When it takes off it moves to a full slot, with the same address, data and deploys.
Archive it: It stops serving and takes no slot. Its export is kept for 12 months, and you can restore it.
Extra full projects: £5 a month each, on any plan.

Pick a price. It won’t change.

Every plan has every feature, except Postgres on Hobby. Nothing is billed by usage.

Questions

What happens when I reach a limit?: Requests over it get a 429 and new data can’t be written until next month. Sign-in and your site keep working.
Will my app pause if nobody uses it?: No. Paid projects stay live. Postgres sleeps when idle and wakes on the next request, or stays awake with Always-on (£15 a month).
Can I leave?: Yes. Export everything, up to 30 days after you cancel.
Where is my data stored?: The EU or the US, per project.
