Drop-in cutting/packing optimization for sheet materials, texture atlases, PCB panelization, CNC nesting. Improve cutting quality, reduce material waste, and get from curl to production faster than building your own optimizer. Greedy for instant feedback, multi-threaded ALNS for better layouts under real production constraints. Hosted API or self-hosted Docker.

Public evaluation goes through api.cutweaver.io, not a downloadable browser engine.
That keeps the optimizer server-side while still giving you a real JSON contract to integrate against.
No key
Run the quickstart request up to 5 times per day per IP to verify payload shape and response parsing.
Free key
Request a reusable evaluation key by email for 25 solves/day and 250/month during integration.
Production
Move live workflows to a paid hosted tier or a licensed private runtime with the same request contract.
Free is intentionally small: enough to validate the contract, not enough to quietly run a real workshop on our infra. If customer quotes, shop-floor jobs, or daily internal workflows depend on the API, start with a paid tier.
Evaluation and hobby use
$0/month
If this tier fully covers your workload, you are still in evaluation territory.

Same email returns the same free key. No separate signup flow.
Use it as X-API-Key for POST https://api.cutweaver.io/api/v1/solve
and GET https://api.cutweaver.io/api/v1/usage.
Commercial hosted usage
from $29/month
The paid ladder starts where free should stop being comfortable.
Temporary path before billing goes live: plan-specific GitHub request. Future checkout replaces only the target URL, not the plan structure.
On-prem and redistribution
from $199/month
Use this when data must stay on your side or the API volume never stops.

Built to improve utilization, reduce scrap, and turn expensive sheet material into more shipped parts per job.
Use fast Greedy for instant quoting and UI feedback, then switch to ALNS when the job deserves deeper optimization.
Beam search, adaptive large neighborhood search, and exact solving for small tail cases give you a practical mix of speed and quality.
JSON API, hosted evaluation, docs examples, or self-hosted Docker. Fit it behind your frontend, ERP, MES, CAD, or quoting flow without UI lock-in.
Given a list of rectangular pieces and sheets (with kerf, margins, rotation, defects), we return a guillotine cutting layout that improves utilization and reduces wasted material. In practice that means faster quoting, fewer manual layout iterations, and better yield on the shop floor.
The core is closed-source. The self-hosted Docker license includes binary distribution rights for end-projects. Public benchmark code and example clients live on GitHub. We do not publish a public browser WASM demo because it would distribute the optimizer engine to every visitor.
OR-Tools needs you to model and tune a CP-SAT problem yourself. rectpack2D is non-guillotine
and lacks production constraints. OptiCut is a desktop app, not an API.
See the engine guide for the current Greedy and ALNS surface.
Because free is for evaluation, demos, and hobby tooling. If evaluation access fully covered a small commercial workflow, we'd be subsidizing production usage and learning nothing about real willingness to pay. Paid tiers start where recurring customer traffic begins.
Today paid access starts through the request flow on this pricing page while billing rails are still being finalized. The target path is provider-backed checkout or invoiced access depending on jurisdiction and customer type, with a Merchant of Record or invoice path instead of a Stripe-only assumption.
OEM-machine integrations (Lisec/Hegla/Bottero formats), ERP modules, end-user UI for SMB producers, custom G-code per machine. We sell to developers, they decide the rest.
