- One agent runs the whole shop.Bambu Lab, Creality, Prusa, Elegoo, Klipper and OctoPrint machines in one fleet. Jobs go to the printer that’s free and fit for them, and what one printer learns, the others get. A printer maker’s own app only sees its own machines. When they’re all busy, order the rest made and shipped, with no Kiln fee on any order.
- Quote it, make it, hand it over with paperwork.A customer’s drawing comes in; Kiln says whether you can make it and what to quote. Parts go out with dimensioned drawings, an assembly manual and a bill of materials under your own name.
- Client work, with a team behind it.Custom orders and client work, on top of selling your own designs. 3 seats, with review and approval gates on every design so nobody prints the wrong version.

Trust
Built to pass a security review.
The parts your security team will ask about — shipped, not promised. On every plan, including Free.
Signed supply chain
Every release ships Sigstore-signed builds and SLSA build provenance, attested in a public transparency log. Two commands prove your download came from our CI, from a commit you can read — no key to trust, nothing we can rewrite after the fact. Each release also publishes a full ingredients list — every third-party library inside Kiln, with exact versions, in both CycloneDX and SPDX — so your scanners can check the whole stack, not just our code.
Check your download is genuine →Spend caps on every account
Outsourced manufacturing orders are capped by default — $500 per order, $2,000 a month — on every plan, Free included. Raising a cap takes a code from your authenticator app, and every change is audit-logged and reversible by email for 24 hours. Your agent can’t outspend your mandate.
Open source where it counts
The engine that touches your printers is AGPL-3.0 on GitHub — auditable line by line. Paid tiers add the hosted workflow around it, never a black box between you and your machine.

Frequently Asked Questions
Is local printing really free?
Yes. Kiln is open source (AGPL-3.0). Local printing, slicing, and printer control are free forever with no limits on print volume.
What is a fulfillment order?
When you outsource manufacturing through Craftcloud via Kiln. Local printing to your own printers does not count.
How does the fulfillment fee work?
You pay the manufacturing provider's own price, and Kiln adds 5% per order for arranging it (minimum $0.25, capped at $200). On Pro, your first 3 orders each calendar month carry no Kiln fee; on Business and Enterprise there is no Kiln fee at all. Free accounts keep 3 fee-free orders a month until 19 November 2026. Order volume is never capped. The fee is exclusive of tax — where your jurisdiction taxes it, that tax is added to the fee only, never to the provider's price.
Can I self-host everything?
Yes. Kiln runs entirely locally. Pro/Business/Enterprise tiers add optional cloud features, but free tier local basic functionality never requires a subscription. Enterprise customers who need Kiln inside their own infrastructure boundary can deploy on-prem or in their VPC.
Do I need a paid plan for multiple printers?
Free and Pro run one printer at a time — you can own several and switch between them, and pausing or stopping any machine you own is free on every tier. Business includes 3 printers running in parallel ($15/mo per additional, up to 50). For larger fleets, Enterprise is custom-quoted.
What's the difference between Pro and Business?
Pro is for individual makers — single user, one printer at a time, and you can sell prints of your own designs. Business is for anyone running a real operation: custom-order businesses, client work, agencies, schools, manufacturers, or any shop running several printers at once. Business adds multi-printer fleet management, team seats, QR codes, and the workflow features small shops actually need. (Both tiers are subscription plans for the hosted product — separate from the AGPL-alternative licensing covered below.)
What does annual billing save?
Annual plans save roughly 20% compared to monthly. Pro drops from $49/mo to $39/mo ($468/yr). Business drops from $199/mo to $159/mo ($1,908/yr). Founding members pay half of either, for life: Pro /mo or a year; Business /mo or a year. Students get half off either for 12 months. Enterprise pricing is custom — annual savings are part of the conversation. You can switch plans anytime from Billing in the Kiln app: a move that costs more (monthly to yearly, or Pro to Business) starts right away, and one that costs less starts when the period you've paid for ends.
What's included in Enterprise?
Enterprise is for teams running production print operations — manufacturing, regulated industries, large fleets. It includes SSO and SCIM provisioning, named-approver e-signatures on design releases, role-based access control, full audit trails, lockable safety profiles, on-prem or VPC deployment options, a dedicated CSM, and a 99.9% uptime SLA. Pricing is tailored per deal — contact us for a quote that fits your team and use case.
Can our security team review Kiln before we buy?
Yes — that review is designed for. Every release ships with Sigstore-signed builds and SLSA build provenance, attested in a public transparency log your tooling can query, and our verification guide shows how to check any download yourself in one command. The local engine is open source and auditable. Under NDA we share the fuller evidence package: our SOC 2 readiness assessment (Type I preparation is in progress — we're honest about that), completed CAIQ and SIG Lite questionnaires, and the on-prem deployment architecture.
What stops an AI agent from overspending?
Spend caps, on every account including Free. When you outsource manufacturing through Kiln, a single order is capped at $500 and your calendar-month total at $2,000 by default. Going above either takes a code from your authenticator app — an agent can't do that for you — and every change is audit-logged and reversible by email for 24 hours. Printing to your own printers is never metered or capped.
Can I try Enterprise before committing?
Yes. Email adam@kiln3d.com and we'll set you up with full Enterprise access to evaluate.
Need a non-AGPL license to use Kiln in proprietary code?
Different from the subscription tiers above. Kiln is open source under AGPL-3.0, which requires that derivative works and networked services built on Kiln also be open-sourced. If your company needs to use Kiln in proprietary products without AGPL obligations, we offer an AGPL commercial license (a dual-licensing alternative — not a subscription tier). Contact adam@kiln3d.com to discuss.
