What each plan gives you

The free simulator is a real product, not a trial — most people never need to pay.

Here is an honest map of what you get whether you stay anonymous, sign in for free, or take the paid plan. Nothing here is designed to push you — it is here so you can decide for yourself.

The capabilities, side by side

Public means using the tool without an account. Free means signing in at no cost. Paid adds a couple of extras. Paid + Planner ties in the side-by-side comparison view and the planner-facing features below.

On the roadmap

These are things we are working toward — a direction, not a promise, and not part of any plan today. We will move them into the map above only once they actually ship.

End-to-end encryption, where only you hold the key and even the database administrator cannot read your scenarios.
Plan-specific extras for the paid plan as the project grows.
Planner-facing features for the Paid + Planner plan — tools for a fee-only planner you choose to share a plan with.

Until then, the free plan stays a complete way to use the simulator.

If the paid extras are useful to you

If saving more than three scenarios or supporting the project is worth it to you, you can see pricing. If not, the free plan is genuinely all most people need.
