SOFTWARE STUDIO · JOHANNESBURG
Built across every platform.
Arcline designs, builds, and ships software across mobile, web, desktop, and the APIs and infrastructure that connect them — handled end to end by one team.

Capabilities
Software for every surface your product touches.
From a native app to the middleware behind it, Arcline works across the whole stack — so the pieces are designed to fit together, not bolted on afterward.
Web applications
Fast, modern web apps and PWAs in React and TypeScript — dashboards, portals, internal tools, and customer-facing products.
Desktop applications
Windows and macOS apps with Electron or native toolkits — for workflows that need to live on the desktop, not just the browser.
API development
Well-documented REST APIs and backend services, designed for the apps and partners that depend on them — and built to keep running.
Integrations & middleware
The connective tissue between systems — custom middleware, data pipelines, and integrations that make separate platforms behave like one.
WhatsApp Business integration
WhatsApp Business Platform integrations — automated messaging, notifications, and omnichannel flows wired into your existing systems.
Hosted infrastructure
Deployment, hosting and DevOps across VPS, bare-metal and cloud. We don't just hand over code — we run it in production.
Product engineering
Idea to launch: discovery, architecture, build and support — one accountable team instead of a chain of hand-offs.
Integrations
Platforms we've built integrations with.
Telephony, messaging, CRM, support and AI — the systems we connect to and build around.

The studio
A small team that goes deep on the hard parts.
Arcline is hands-on engineering, not a layer of management between you and the people writing the code. We come from telephony, integrations and infrastructure — the kind of systems that have to keep working — and we bring that discipline to everything we build.
