Every app has limits on how much a single customer can do. How many requests a minute, how many projects, how much they can upload. When an AI builds these, it treats them as a safety switch to stop someone hammering the system. That is one job they do. It is not the important one.

A limit is a quiet price tag

Where you set a limit tells a customer how much of your product they are allowed to have before they pay you more. That is a pricing question wearing technical clothing. Left on its defaults, those numbers get chosen to protect the server and nothing else, which means one of the levers that decides your revenue is being set by whatever figure felt safe at the time.

It is worth designing on purpose from the start, because the same limits also decide whether the product feels generous or stingy, and whether it slows down gracefully or slams into a wall when it is busy.

Tell your AI: "Show me every usage limit in the app and the exact number each is set to. I want to treat these as pricing decisions, not just safety settings."

Three kinds of limit, doing three different jobs

  • The hard ceiling. One fixed limit whose only purpose is to stop obvious abuse, a script gone wild or someone probing your system. Set it high enough that a genuine power user never once brushes against it. If real customers are hitting this, it is set wrong.
  • The limit that reads the room. A cap that flexes with how healthy the system is: generous when things are calm, tighter when the app is under strain. This lets the product ease off under pressure instead of failing outright, so a busy moment feels like a mild slowdown rather than an outage.
  • The limit tied to the plan. Caps that match what someone is paying for. This is the one wired directly to your pricing page, and the one most worth thinking through.

Tell your AI: "Sort our limits into three kinds: a high anti-abuse ceiling, a limit that tightens when the system is under load, and limits tied to each plan tier. Tell me which of ours is which."

A free tier has to leave a reason to pay

The free tier is where this really gets decided. It has to be generous enough that someone can feel the product working and see why it is worth having. If it is too thin, nobody stays long enough to be convinced.

But a free tier that does everything the paid one does, with no ceiling a real user ever reaches, quietly removes any reason to upgrade. You have handed your heaviest users a permanent home on the plan that pays you nothing. The free tier should prove the value completely and then, for anyone leaning on it hard, run out of room in a way that makes upgrading the obvious next step.

Tell your AI: "Set the free tier so it fully proves the product's value but runs out of headroom for a heavy user, giving them a clear reason to upgrade. Show me where that ceiling sits."
