The plan catalog: Free, Starter, Pro, and Scale

HIIE offers four plans. The Free plan is built around bringing your own keys; the three paid plans give you managed inference credits so you don't have to manage keys yourself.

The four plans

• Free (BYO) — $0. 0 monthly credits, ~500 MB storage. Bring your own Composio / OpenRouter keys and run the full orchestration engine and flows under fair use.
• Starter — $20/mo. 1,400 credits per month, 5 GB storage. Managed inference, any model, no BYO key required.
• Pro — $99/mo. 6,930 credits per month, 50 GB storage. For serious building.
• Scale — $150/mo. 10,500 credits per month, 200 GB storage. Dedicated CAD + Composio capacity and priority queue.

How credits are granted

Paid plans grant credits using the formula price × 100 × 0.70 — a 30% platform margin is taken once, at grant. That's why Starter's $20 yields 1,400 credits (worth $14 of actual inference value), and so on. One credit equals $0.01 of real inference value.

Choosing a plan

If you already have an OpenRouter key, Free gives you the full engine at $0 with unmetered runs. If you'd rather skip keys, pick the paid tier whose monthly credit grant matches your expected usage — and remember you can add one-time top-ups on top of any plan. Upgrades and downgrades are handled in the billing area.
