STATIX gives a practising structural engineer 3D frame analysis, steel member design to SANS 10162, reinforced-concrete design, cold-formed purlins by the Direct Strength Method and native CBFEM connection design — in the browser, with clause-by-clause reports. Every closed-form engine is checked against published worked examples.
Full suite for 14 days. Cancel anytime. For scale: Prokon Complete is R71,840 a year — STATIX is R10,000.
Analysis, member design, connections and reports in one tool — priced so a sole practitioner can afford it, and validated so a reviewer can trust it.
Every closed-form engine is checked against published worked examples — RC flexure to SANS 10100 / BS 8110, EN 1993-1-8 bolts and welds, wind pressures, torsion constants, bearing capacity, steel in fire — at errors of hundredths of a percent. The full build passes its 44-check self-certification. See the benchmarks.
Component-based FEM connection design is built in. Solve the frame, click a joint, design the connection — no export to a second product, no second licence. Audited line-by-line against IDEA StatiCa verification examples and SCI worked examples.
SANS 10160 loading, SANS 10162 steel, SANS 10100 concrete and SANS 282 bending schedules as first-class citizens — with EN, AISC 360, CSA S16 and AS 4100 on the same model when a project crosses a border.
Calc sheets cite the code clause at every step — classification, buckling curve, interaction — so a reviewer traces each number to a published rule instead of taking the software's word for it.
STATIX runs in the browser on Windows, macOS or Linux. Sign in and work. It also reads existing .sumo models — nodes, members, sections, supports and loads — and cross-checks the imported results against its own solver.
R1,000 a month — or R10,000 a year, two months free — buys the whole suite: analysis, all design modules, connections, calculators and reports. No per-module pricing, no add-ons. Prokon Complete lists at R71,840 a year.
Six working areas, one model, one report. The product page covers each in depth.
Bolts, welds, plates and prying — the part of the design most tools hand off to a second product. STATIX designs it in the same model.
The usual workflow is two products: analyse the frame in one, export forces, rebuild the joint in a connection package, and keep both licences current. STATIX collapses that. Solve the frame, open the joint, and the Connection Studio meshes the plates, springs the bolts and lines the welds — with every capacity anchored to the EN 1993-1-8 component method.
Trust in engineering software is earned one benchmark at a time. These are actual results from the shipped build against published references — the same functions the app runs, not a demo path.

Plus: the frame FEM verified against closed-form statics and Euler buckling, slab FE against Timoshenko plate theory, and a 44-check build self-certification — all documented with references.
Start page, 3D modeller, Connection Studio, whole-frame analysis and FE slabs — one interface, one project.
One model, five steel member-design standards. Switch the code; the capacities change because the rules change — not the labels.
The conventional setup is an analysis suite priced per module, plus a separate connection-design product with its own licence. STATIX puts the whole workflow in one plan.

| CBFEM connection design | Included — native | Separate product + export round-trip |
| Cold-formed purlins (Direct Strength Method) | Included | Design module |
| Bar bending schedules to SANS 282 | Included | Detailing module |
| Runs in the browser, cross-platform | Yes | Windows desktop install |
| Published validation benchmarks | Yes — open record | Varies |
| Annual cost | R10,000 (or R1,000/month) | Prokon Complete: R71,840 (list) — connection design software extra |
Prokon Complete annual list price of R71,840 is Prokon's published South African pricing (mid-2026) and may change. Third-party product names are the property of their respective owners and are referenced for factual price and workflow comparison only.
No tiers, no per-module add-ons, no surprises at renewal. Try the full suite free for 14 days, then R1,000 a month — or R10,000 a year and get two months free.
For scale: Prokon Complete is R71,840 a year — about seven times the price, before adding separate connection-design software.
Open the app, model a frame, run the analysis, design the members and the connections, and print a report a checker can follow. The first 14 days cost nothing.
STATIX is developed in South Africa by the STATIX design team, out of a specific frustration: the tools a small practice needs are split across expensive per-module desktop packages, and none of them handles both SA-code analysis and real CBFEM connection design in one place.
The response is one tool with the SANS codes built in natively — loading, steel, concrete, detailing — a validation record that is published rather than promised, and a price a sole practitioner can justify.
Professional responsibility. STATIX is a design aid. It does not replace engineering judgement, and a registered professional engineer must review and take responsibility for every production design. See the engineering disclaimer.
