Simple pricing. No feature gates, ever.

Yes. Versions published under MIT remain MIT for those versions. This dual license applies from the version that carries it onward.

No licence here is perpetual — every tier, free ones included, is a 12-month term (LICENSE §10; COMMERCIAL.md clause 3). Free tiers renew automatically at no charge while you stay eligible; paid tiers renew on payment. If a paid licence lapses, the right to use, embed, and distribute NativeCAD ends with it: you stop using it and remove it from your machines, and anything you shipped carries the same obligation down to your customers and theirs. Geometry and drawings you produced while licensed stay yours, unencumbered — the removal obligation reaches the software, never your output.

Competitors. No licence — free or paid — is available to the Excluded Parties in LICENSE §9: Dassault Systèmes, Siemens, Autodesk, PTC (incl. Onshape), Ansys, Hexagon, Bentley Systems, and Trimble, among others named there, plus their affiliates, any other competitor, and the employees and contractors of any of them — in any capacity, personal or commercial. And whoever you are, publishing benchmarks or feature comparisons needs prior written consent, and using NativeCAD to build or train a competing product or model is prohibited (LICENSE §11).

Beyond the 7-day evaluation, yes. Designing with NativeCAD for revenue-generating work needs a seat, one per person doing it. Building the kernel into a tool you then distribute — to customers, or to another company — needs the Kernel SDK.

Free under the Non-Commercial License if the project is distributed non-commercially. If your OSS project is itself a commercial product's core, talk to us — OSS-friendly terms are available.

Free, including funded research. Publication of results requires no license; shipping a commercial spin-out does.

A seat if NativeCAD stays on your side of the line: you design with it and what reaches anyone else is geometry — STEP files, meshes, drawings, CAE decks. The Kernel SDK if a copy of NativeCAD ends up in someone else's hands as part of what you ship. Both, if both are true, because they license different things and are priced independently. The operative terms are grant clause 9 (seats) and grant clauses 1-7 (embedding) in COMMERCIAL.md.

An agent, and that is why the answer arrives at 3am on a Sunday instead of on Wednesday. A human is behind it for anything the agent can't close, and gets your full transcript when it escalates. See Automatic Support above.

Not inside a term you've already paid for. The model tokens the agent uses are our cost, not yours — no API key, no account, no usage bill. The full terms, including the fair-use envelope and exactly what happens if you run past it, are in the "What the tokens cost" panel above and in COMMERCIAL.md grant clause 8.

No. The kernel and viewer are fully functional on every tier — see "How the license actually works" above. A key only removes the attribution watermark and covers you for commercial use.

Automatically. Polar confirms the payment and the key (CSLV1-…) is issued and e-mailed to the address on the order. If it hasn't arrived, claim it at featureboard.ai/claim with your receipt e-mail address and order id, or e-mail support@featureboard.ai directly.

Yes, on either plan. Use the "Prefer invoice, wire, or a PO?" link next to it instead of the checkout button and we'll raise an invoice; the key follows on payment.

Buy them: seats are $200 each and the checkout takes a quantity. A seat is named rather than floating, and can be reassigned when its holder durably stops using it (grant clause 9.2). The Kernel SDK has no developer count to exceed. There's no automatic overage charge or shutoff either way — staying within your licence's terms is what keeps it valid.

E-mail support@featureboard.ai with your order id and we'll sort it out directly — there's no self-serve cancellation flow yet. Polar is the merchant of record, so the receipt and any refund come from Polar.
