Software
that reaches
new heights.
A growing catalogue of desktop applications and engineering tools, built end-to-end. For workflows where off-the-shelf software won't cut it — designed, built, and shipped by the engineer writing the code.
Focused desktop software, built to last.
Zenith Software Solutions is a South African indie software house building a growing catalogue of desktop applications and engineering tools. Each product targets a specific problem in domains where off-the-shelf software falls short — chemical engineering, process workflows, technical research.
Built around mature, maintainable technology and clear architecture. No frameworks-of-the-week, no SaaS lock-in — just software that runs on your machine, owns your data, and earns its place.
Desktop tools for engineers and technical teams.
Windows software that runs on your own machine and keeps your data local. Subscriptions can be cancelled any time without an account, and many products come with a free trial.

Scientific & Engineering SoftwareZenith Process Optimisation
Response surface modeling and process optimisation, without the bloat.
Zenith Process Optimisation is a desktop application for engineers, scientists, and analysts who need to turn experimental data into decisions. Fit polynomial and non-linear models, run full statistical diagnostics, design experiments, and find optimal conditions for processes, products, or formulations — all from a single Windows install. Connects briefly to verify your license at launch, then runs fully offline — your data and models never leave your machine. No cloud, no recurring uploads, and no learning curve borrowed from a generic stats package. Choose the license that fits your workflow: subscription or perpetual.
- Polynomial regression
- Non-linear curve fitting
- Single and multi-response optimization

ProductivityZenith Data Extractor
Turn any graph back into data.
Zenith Data Extractor turns images of charts back into usable numbers. Load any plot — a scanned pump curve, a datasheet figure, a published graph — trace each line with smooth spline handles, set your axes (linear or log), and extract clean, point-by-point data in seconds. You get a styled Excel workbook, a high-resolution regenerated chart, and an annotated overlay you can trust. Built for engineers and analysts who need the data, not just the picture.
- Spline curve tracing — drag-to-fit handles with zoom
- pan
- and a live magnifier

ProductivityZenith Reckon
Math the way you think it.
Zenith Reckon is a scratchpad calculator with units, variables, and live results. Type expressions on the left and answers appear on the right as you type — each line is one calculation, and the names and units you use carry through the whole sheet. Mix units freely, reference physical constants by name, define your own functions, and solve, differentiate, or integrate them numerically. Built for engineers, scientists, and students who reach for a calculator several times a day. Reckon docks to the side of your screen, auto-saves between sessions, and stays out of your way until you need it.
- live results as you type
- multi-line scratchpad
- persistent variables across lines
