CutList Optimizer vs OptiCutter: Which Should You Use?

CutList Optimizer and OptiCutter are two of the most searched browser-based cut list optimizers. Both nest rectangular parts on sheet goods, apply kerf, and export cutting plans - but they target slightly different users.

CutList Optimizer leans free and simple. OptiCutter leans toward polished reporting, DXF export, and a planner API. Cutlistor adds real-time editing, CAD/AI import, and DXF export for sheet and linear layouts. This comparison breaks down where each wins.

CutList Optimizer (cutlistoptimizer.com) is the default free choice for hobbyists and small shops. You enter parts and stock, set kerf and grain, click calculate, and get a nested diagram with a PDF report.

It shines for occasional panel jobs where you do not need costing, labels, or integrations. The trade-off is a manual recalculate after each edit and limited spreadsheet import, which slows revision-heavy work.

• Best for: hobbyists and small shops nesting simple panel jobs for free
• Strength: zero cost, trusted, minimal learning curve
• Weakness: manual recalc, basic linear mode, limited import, no AI/CAD takeoff

OptiCutter targets users who want cleaner reports and production features. Paid tiers advertise DXF output for CAM post-processors, cost and priority optimization objectives, material groups, and a planner API for unattended optimization.

If your plant integrates optimization into other software via a REST planner API, or procurement requires cost/priority objective tooling beyond standard nesting, OptiCutter is built for that. Both OptiCutter and Cutlistor export DXF for CAM post-processors; Cutlistor pairs DXF with real-time layout refresh and design-file import. Casual users may find OptiCutter's free ceiling lower than CutList Optimizer's.

• Best for: CNC vendors, multilingual plants, and teams needing planner API integrations
• Strength: professional reports, costing objectives, integration options
• Weakness: limited free access; less focus on live editing and CAD/sketch import

Both tools share one limitation: editing is a stop-and-recalculate loop. If your day is full of dimension changes, that friction adds up.

Cutlistor refreshes layouts and yield in real time as you edit, runs a dedicated linear optimizer alongside sheet nesting, and imports from spreadsheets and 3D CAD so you are not retyping a BOM. DXF export for sheet and linear layouts hands off to laser cutters, routers, and CAM alongside the iteration speed and import pipeline revision-heavy shops need.

• Real-time sheet and linear layouts - no manual solve step
• Four sheet layout methods to match table-saw or CNC workflows
• CSV/XLSX import, plus AI plan scan and glTF/GLB/Collada CAD import on paid plans
• Kerf-aware labeled PDF cut plans for the shop floor
• DXF export for sheet and linear cut layouts

Do not pick on a feature list - run the same job through each tool. Import one real BOM, match kerf, lock grain on visible faces, and generate a PDF in each.

Then change one part's width by a few millimeters and time how long it takes to get an updated plan. Compare PDF readability under shop lighting. The tool that survives the edit cycle is the one to keep.

CutList Optimizer wins on free and simple; OptiCutter wins on reporting depth and planner API integrations. Neither is built around real-time editing or design-file import — and neither matches Cutlistor on DXF export combined with CAD/AI ingest and live layout refresh.

If you are choosing today: stay on CutList Optimizer for casual free nesting, choose OptiCutter when costing objectives or a REST planner API dominate procurement, and try Cutlistor when constant revisions, spreadsheet/CAD import, combined sheet plus linear work, or DXF handoff to CAM define your jobs.
