GoSmarter vs Lantek, Sigmanest, and Bystronic for Cutting Planning

GoSmarter handles long product cutting optimisation for rebar, sections, and tubes. Lantek, Sigmanest, and Bystronic handle 2D plate and sheet nesting. They are not competing for the same job.

GoSmarter and Lantek/Sigmanest/Bystronic are not doing the same job.

If you are searching for “cutting optimisation software” and these names are all coming up together, that makes sense. They all optimise cutting in a metals context. But the type of cutting they handle is fundamentally different. Buying the wrong one based on a feature comparison table would be a waste of time and money.

This post explains exactly what each tool does, where the overlap is thin, where GoSmarter wins, and where the nesting tools win. By the end, you will know which one you need and, in some cases, why the answer is both.

What Type of Cutting Does GoSmarter Handle?

GoSmarter Cutting Optimiser is built exclusively for long product cutting: rebar, structural sections (I-beams, channels, angles), tubes, hollow sections, and similar linear stock.

The problem GoSmarter solves is this: you have lengths of steel coming in from a mill or stockholder (typically 6m, 9m, 12m, or as-rolled). You have a set of cut orders: pieces needed for a project, a fabrication job, or a customer order. GoSmarter calculates the optimal way to cut your available stock to fulfil those orders with the least possible trim waste, fewest bar changes, and the lowest overall material cost.

It does this in seconds, stores the cut plan against the order, and, critically, links that cut plan to the mill certificates for the material being cut. So when an inspector asks which heat of steel went into which structural member, you have the answer immediately.

GoSmarter does not do 2D plate nesting. It does not optimise cutting on sheet, plate, or flat material. If you cut flat plate, you need a different tool.

What Lantek, Sigmanest, and Bystronic Do

Lantek, Sigmanest, and Bystronic’s software products are primarily 2D nesting and sheet/plate cutting optimisation systems. They are built to maximise material utilisation when cutting shapes from flat sheet: whether by laser, plasma, waterjet, or guillotine.

Sigmanest is the long-standing specialist nesting software, used by sheet metal fabricators and structural steel plate processors alike. Lantek is similar in scope, strong on CNC machine integration and multi-site manufacturing environments. Bystronic is both a machine manufacturer and a software provider; its nesting tools are tightly integrated with its own cutting machines.

Most of these platforms also have some long product or bar cutting capability: it is not zero. Lantek, for instance, has bar cutting nesting modules. But the long product cutting in these platforms is typically an add-on to a 2D nesting system, not the primary purpose. The configuration, pricing, and training are all geared toward the plate/sheet customer.

For a metals stockholder or structural fabricator whose primary job is cutting rebar, sections, or tube to length: these platforms are built around a different workflow.

Where GoSmarter Wins

See GoSmarter Cutting Optimiser in action:

Deployment speed. GoSmarter is live in days, not months. There is no IT project. You do not need a dedicated server, a specialist Value Added Reseller (VAR), or a three-week implementation engagement. You create an account, upload your stock, and start generating cut plans. For an SME with two or three people managing the yard, that matters enormously.

Pricing. Lantek, Sigmanest, and Bystronic are enterprise software. Their pricing reflects that: seat licences, annual maintenance agreements, and professional services add up quickly. GoSmarter starts at £400/month with no implementation fees and no long-term lock-in. For a business doing £2–5m turnover in steel, the economics are completely different. Enterprise nesting platforms typically run £10,000–£50,000+ per year once implementation and maintenance are included.

Vendor trust and data security. GoSmarter is EU-hosted and GDPR compliant. Your data is exportable as CSV at any time. No exit fees. If you cancel, you have 30 days to export your data. For an SME that cannot afford vendor lock-in, that matters.

No IT dependency. GoSmarter is browser-based SaaS. Nothing to install, nothing to maintain. Your team uses it on whatever devices they already have. The nesting platforms typically require Windows workstations, local installation, and someone who knows how to set them up.

Mill certificate integration. This is where GoSmarter is genuinely unique in the long products space. Every cut plan is linked to the source material’s mill certificate. When you process an EN 10204 (the European standard for mill test certificates for metallic materials) 3.1 cert through GoSmarter, the traceability chain is maintained automatically, from the incoming coil or bar through to the finished cut piece. Lantek and Sigmanest are not designed to handle this. It is not their problem to solve.

SME fit. GoSmarter was built for metals small and medium-sized enterprises (SMEs). The interface, the onboarding, the support model. Everything is designed for a team of one to ten people running a steel yard or fabrication shop, not for a 500-seat enterprise with a dedicated IT department.

Where Lantek, Sigmanest, and Bystronic Win

Plate and sheet nesting. If you cut flat material: steel plate, aluminium sheet, stainless, anything that starts as a flat shape and gets cut into 2D profiles: GoSmarter cannot help you. Full stop. This is not a feature gap that GoSmarter plans to close. It is a deliberate scope choice. Lantek, Sigmanest, and Bystronic are the right tools for 2D cutting optimisation.

Computer Numerical Control (CNC) machine integration. The nesting platforms have deep integrations with laser cutters, plasma tables, waterjets, and guillotines. They produce machine programs (DXF, DNC files, G-code) directly from the nesting output. GoSmarter produces cut lists and bar charts that operators use to set up manual cutting; it does not connect to a CNC controller.

Complex multi-material, multi-machine environments. Large fabricators running plate processing, section cutting, and tube processing simultaneously, across multiple machines and sites, are better served by the enterprise nesting platforms. The workflow management and scheduling complexity in those environments is exactly what Lantek and Bystronic are built for.

Structural detailing integration. For structural steel fabricators using Tekla Structures, Advance Steel, or SDS/2, Lantek and Sigmanest have integrations that pull BOMs directly from the detailing model. GoSmarter does not currently integrate with structural detailing software.

Side-by-Side Comparison

Can You Use Both?

Yes, and for some businesses this is exactly the right answer.

A structural steel fabricator might use Lantek or Sigmanest for plate processing (cutting plates to profiles for columns, base plates, connection details) and GoSmarter for bar and section cutting. These are genuinely different operations in the same yard, handled by different people, using different machines.

In that scenario, GoSmarter handles the long product side: bar cutting to length, remnant tracking, mill certificate management. Lantek or Sigmanest handles the plate side. There is no overlap, no duplication. They do different jobs.

The GoSmarter team has spoken to businesses running exactly this combination. The integration is not automated; both systems run independently. But that is fine, because the workflows are separate anyway.

Decision Framework: Which Tool Do You Need?

Choose GoSmarter Cutting Optimiser if:

• Your primary cutting operation is long products (rebar, sections, tubes, hollow sections)
• You need mill certificate traceability alongside cutting plans
• You are an SME and enterprise pricing is out of reach
• You need to be operational within days, not months
• You do not have in-house IT to manage software installations

Choose Lantek, Sigmanest, or Bystronic if:

• You cut flat sheet, plate, or profiled 2D shapes
• You need CNC machine program output (laser, plasma, waterjet, guillotine)
• You integrate with Tekla Structures or other structural detailing software
• You run a multi-machine or multi-site production environment
• You have the IT resource and budget for an enterprise platform

Consider both if:

• You cut both long products and flat plate/sheet in the same operation
• Your plate processing and section/bar cutting are genuinely separate workflows
