FractalPack is the optimization engine for your connected supply chain. Recover wasted volume, right-size every carton, and prove the decision behind each pack — through one API, plugged into the systems you already run.
Plugs into the systems you already run
Space is the constraint. We solve it.
An optimization engine that decides how to pack, right-sizes the carton, and shows its work — all from one API.
A 3D bin-packing engine that tests every orientation at every open space, nests items into void cavities, and splits across the fewest containers when one won't do.
Stop shipping air. The engine picks the right box from your assortment — or tells you which boxes you should be carrying — to cut wasted volume, material, and dunnage.
A rules engine you configure and a per-order explain trace that shows why each item landed where it did — plus an interactive 3D viewer and usage dashboard.
What's wasted space costing you?
Tighter packs mean fewer containers, less packaging material, and lower handling cost per order. Move the sliders to ballpark your annual recovery.
Combines fewer containers, less packaging material, and lower handling. Typical range for under-optimized operations.
Illustrative estimate only, for planning purposes — not a quote or guarantee. Actual results depend on your catalog, carton assortment, and current packing process.
One request. Optimal packing.
JSON in, exact coordinates out. No SDK required — integrate in any language in minutes.

}Built for operations that move volume
Standardize cartonization across every client and surface savings you can put in a QBR. ERP-ready, SAP-first integration.
Cut box spend and packaging waste at scale without re-tooling your WMS — one API call from your existing order flow.
Embed FractalPack's optimization engine into your own product. Clean REST, predictable JSON, and a 3D viewer you can ship to your users.
Container dimensions, item sizes, weights, quantities, and any packing rules. Optionally define void spaces for nesting.
One POST. The engine evaluates every orientation and position, applies your rules, and selects the right container.
Exact X/Y/Z placements, volume utilization, and an explain trace for every decision.
We're onboarding a small group of high-volume operations to shape the roadmap — with hands-on integration support and committed-use pricing. Tell us about your operation.
