As answered by people managing Flatfile and CargoOptix.
CargoOptix's answer:
CargoOptix plans the order, not just the load. Most load planners stop at “does it fit?” CargoOptix goes further: * Spare Capacity Finder: after packing, it shows how many more of your own products would still fit, with an add-to-order list, so you can top up before the container ships. In our sample job, that took a container from 30% to 92% full. * Crew-ready loading order: the plan packs far wall first, the way a crew really loads. It comes with a step-by-step 3D loading guide for the warehouse. * Your data never leaves your browser: the solver runs locally (JavaScript worker plus WebGL), so manifests and cargo data are not uploaded to our servers. * Gross mass, centre of gravity and axle-load checks in one report. These support your SOLAS VGM process but do not replace the shipper’s signed declaration. * Wide equipment catalog: 20/40/45 ft standard and high cube, reefers, open tops, 53 ft vans, tautliners and box trucks. It also covers EUR, GMA, Asia and UAE & Australia pallet standards.
CargoOptix's answer:
CargoOptix's answer:
CargoOptix is for freight forwarders, NVOCCs and LCL consolidators, 3PLs and warehouse teams, and exporters and shippers who pack cartons or pallets into sea containers and road trailers. It’s strongest for UAE and GCC logistics teams, and it works anywhere containers are loaded. Typical users are load planners, dispatchers, export coordinators and procurement or sales-ops staff who place orders and want every container full.
CargoOptix's answer:
After seeing how much freight money disappears into half-empty containers. Hand-planned loads often leave a lot of dead air, and many planning tools stop at “does it fit?” without helping the buyer decide what else to order. CargoOptix started as a browser-based 3D planner and grew to cover the whole decision: the load plan, the loading sequence for the crew, the weight and balance checks, and the spare capacity you could still use. It runs locally in the browser so customers’ manifests stay private. It is still run by the person who writes the code, so user feedback goes straight into the product.
