EXPERTISE
WHAT WE DO
We build Electron applications that run on Windows, macOS, and Linux from a single codebase, handling platform differences in window chrome, file system paths, and OS conventions.
We structure Electron apps with strict main/renderer process separation, contextBridge for secure IPC, and contextIsolation enabled, preventing the security vulnerabilities common in poorly architected Electron apps.
We implement system tray icons, native menus, notifications, file associations, protocol handlers, and OS-level keyboard shortcuts that make the app feel like a true desktop citizen.
We configure electron-updater with code-signed releases, differential update support, and staged rollout so users receive updates silently without manual download or installation.
We handle Apple notarisation, Windows Authenticode signing, and Linux AppImage/deb/rpm packaging, meeting the requirements of macOS Gatekeeper and Windows Defender.
We reduce startup time with lazy module loading, optimise memory usage by managing renderer process lifecycle, and profile the V8 heap to eliminate leaks in long-running desktop sessions.

CASE STUDIES
Testimonials
What impressed us most was how Kultrix handled the full stack - frontend, backend, and mobile - with one cohesive team. Communication was clear, delivery was predictable, and the final product exceeded what we initially scoped.
Co-CEO
Kultrix built both our web platform and mobile app from scratch. Their team understood the complexity of our industrial workflows and translated them into clean, intuitive interfaces. We launched on time and our operators adopted the tools immediately.
Co-CEO
Kultrix handled everything for us - landing page, dashboard, mobile app, and even a Chrome extension. Having one team own the entire product surface meant everything felt connected and consistent. They shipped fast and the quality speaks for itself.
CEO, Ping Proxies
Kultrix has been our go-to partner for multiple projects - from marketing websites to full mobile applications and backend systems. They scale up when we need speed and maintain consistency across every project. Reliable, fast, and technically strong.
CEO, Volume Apps
Working with Kultrix on our mobile app and backend was seamless. They brought strong product thinking to every sprint, not just code. When priorities shifted, they adapted quickly without losing momentum. Exactly the kind of partner a product team needs.
Product Lead, Pelago
We needed a team that could handle mobile development, server infrastructure, and AI features all at once. Kultrix delivered on all three fronts. Our fitness platform went from concept to production in under four months with zero compromises on quality.

FAQ
Electron is a framework for building cross-platform desktop applications using web technologies - HTML, CSS, JavaScript, and Node.js. It is the right choice when you want to target Windows, macOS, and Linux from a single codebase, and when your team has more web than native development experience. Electron powers VS Code, Slack, Figma, and many other major desktop applications. The tradeoff is a larger application bundle and higher memory usage compared to native apps - acceptable for productivity tools but less so for system-level or performance-critical software.
Standard placement is within 48 hours of contract signing. For projects requiring deep native integration (e.g., USB/HID devices, COM ports, GPU access), allow up to one week. We keep Electron-experienced developers available at all times for standard desktop application work.
Electron runs in two processes: the main process (Node.js, full OS access) and the renderer process (Chromium, sandboxed). Our developers communicate between them exclusively via the contextBridge with contextIsolation enabled - never exposing the Node.js environment to the renderer directly. This prevents a class of security vulnerabilities where malicious web content can access the file system or execute arbitrary code.
Yes. We implement system tray applications with dynamic menus, dock badge counts, native notification centre integration, global keyboard shortcuts, file open/save dialog boxes, protocol handler registration, and drag-and-drop from the file system. For features not available through Electron's built-in API, we can write native Node.js addon modules using node-addon-api.
Auto-updates are implemented with electron-updater, which supports delta updates (only downloading changed files), staged rollouts to a percentage of users, and silent background update downloads that prompt for restart. Updates are served from your own S3 bucket or GitHub Releases. On macOS, the app must be notarised by Apple before auto-updates work correctly - our developers handle the complete notarisation pipeline.
Code signing is non-negotiable for distribution. On macOS, apps must be signed with an Apple Developer ID certificate and notarised with the Apple notary service, then stapled for offline verification. On Windows, apps are signed with an Authenticode EV or OV certificate to avoid Windows Defender SmartScreen warnings. We set up the signing pipeline in CI so every release build is automatically signed and verified.
Yes. Electron apps can consume APIs just like web applications - using fetch or axios in the renderer process, or the Node.js http module in the main process for requests that require bypassing CORS. We handle authentication with stored tokens (encrypted in the OS keychain via keytar), offline queuing of mutations, and background sync workers that keep the desktop app in sync with the server.
Electron startup time is a common complaint. We reduce it by lazy-loading modules that are not needed at startup, splitting the webpack bundle to defer non-critical code, using V8 bytecode caching with electron-link, and showing a native splash screen while the renderer initialises. On macOS, login items and background activation further improve the perceived responsiveness.
Yes. We regularly join existing Electron projects to add features, fix security vulnerabilities (especially improper contextIsolation configuration), update to newer Electron versions, improve performance, or add auto-update support to apps that were previously distributed manually. We begin with a security and architecture audit before proposing changes.
React and TypeScript is our default renderer stack for Electron applications, built with Vite for fast development iteration. We use electron-vite or electron-forge as the build tool. For projects with existing Vue.js or Svelte renderer code, we work within the existing choice. The renderer technology is largely independent of Electron itself and follows your team's preferences.
For user preferences and small structured data, we use electron-store (JSON file-backed, encrypted for sensitive values). For larger local datasets, we embed SQLite via better-sqlite3 - which provides synchronous access without an async driver overhead. For apps that need to sync with a remote database, we implement a local-first architecture with background sync.
We offer monthly retainer and time-and-materials models. Retainer engagements lock in a fixed monthly developer allocation at a fixed rate with guaranteed availability. T&M engagements are billed weekly against tracked hours with transparent timesheets. Both models include weekly progress reports and a dedicated account manager. The minimum engagement is one month.
