Desktop software built for speed, offline resilience, and deep hardware integration.
We engineer lightweight, mission-critical desktop applications with Tauri and Electron. Sub-10MB installers, instant startup, local SQLite offline storage, and native hardware drivers for printers, scanners, and counter peripherals.
Tauri production installer size
Idle RAM consumption vs 500MB+
Offline-ready SQLite storage
Windows, macOS & Linux from one codebase
What We Do
Desktop engineering where failure is not an option.
When business operations happen at billing counters, hotel front desks, industrial warehouses, or offline medical clinics, browser applications fall short. Connectivity drops, browser tabs crash, and local hardware like thermal receipt printers and barcode scanners are notoriously difficult to control.
We build production desktop applications with Tauri and Electron. Our own flagship product, POSflow RestaurantOS, ships as a hardened Tauri desktop app operating in busy commercial kitchens and restaurant counters. We bring that battle-tested hardware integration, memory optimization, and code-signed auto-updating to your custom software build.
Where This Fits
Choose the right platform surface for your requirements.
Desktop software, mobile apps, and web portals solve fundamentally different operational constraints.
Desktop App Development
Workstation and counter software for Windows, macOS, and Linux. Offline SQLite persistence, sub-10MB installers, and direct hardware serial/USB integration.
Mobile App Development
Cross-platform mobile applications for smartphones and tablets. Push alerts, GPS, and App Store / Play Store releases.
Web Application & SaaS
High-performance web apps, marketing sites, and cloud portals accessible via URL with green Core Web Vitals.
Key Challenges We Solve
Where typical desktop software fails.
Bloated Installers & RAM
Legacy Electron apps dumping 150MB+ Chromium browsers into user machines, consuming 500MB+ RAM and stalling older counter PCs.
Internet Dependency
Web-based systems that freeze or crash when ISP connections drop, halting billing, checkouts, and physical operations.
Peripheral Disconnects
Flaky browser print dialogs, unformatted thermal receipts, and inability to read raw serial barcode scanners or cash drawers.
OS Security Warnings
Unsigned binaries triggering frightening Windows SmartScreen warnings and macOS Gatekeeper rejections that destroy customer trust.
Why POSflow
We build and ship real desktop products every day.
POSflow RestaurantOS is a production Tauri application deployed to restaurant front-desks and billing counters. It runs all day, processes thousands of orders completely offline in local SQLite, connects to ESC/POS thermal printers via serial/USB, and auto-syncs with the cloud.
Tauri Production Experience
We don't just read the docs. We operate live production Tauri applications with Rust backends and SQLite caching under high transactional counter loads.
Sub-10MB Featherweight Binaries
Tauri leverages the OS-native webview (WebView2 / WebKit). Installers download in seconds and boot almost instantaneously.
Direct Hardware Driver Bridges
Native communication with USB and Serial (RS-232) thermal printers, barcode scanners, cash drawers, customer pole displays, and scales.
Hardened SQLite Offline Engine
Local database persistence using Write-Ahead Logging (WAL) ensures zero data loss during network outages with silent background cloud synchronization.
Code Signing & Auto-Updates
Complete Windows Authenticode signing, macOS Apple Notarization, and cryptographic auto-update pipelines that patch user systems silently.
Full IP & Source Ownership
Clean Rust and TypeScript source code delivered directly to your company repository. Zero per-seat licensing fees or proprietary vendor ties.
What We Build
Desktop software engineered for mission-critical operations.
Point-of-Sale (POS) & Billing
Rapid barcode scanning, instant billing calculation, offline transaction buffering, and high-speed ESC/POS receipt generation.
Hardware Terminals & Kiosks
Locked-down kiosk interfaces, digital queue number displays, thermal kitchen ticket printers, and customer-facing pole screens.
Offline Warehouse & Inventory
Heavy stocktaking applications, SKU barcode generation, shipment manifests, and warehouse pallet tracking with local data caching.
Desktop Utilities & Daemons
System tray background agents, local file synchronization engines, secure desktop backup tools, and VPN/proxy desktop clients.
Electron to Tauri Migrations
Rebuilding bloated Electron applications in Tauri to slash installer size from 150MB down to 8MB and reduce memory footprint by 80%.
Enterprise Licensing & Vaults
Hardware-locked machine licensing, cryptographic key vaults, biometric login bridges, and compliance auditing workstations.
Audio & Media Workstations
High-throughput audio recording tools, video encoding utilities, image batch processors, and local format conversion desktop suites.
Clinical & Lab Terminals
Offline patient record workstations, medical imaging viewers, laboratory diagnostic tool interfaces, and DICOM peripheral integration.
Platforms & Frameworks
Tauri and Electron. Two distinct engineering pathways.
We evaluate your native dependencies, hardware requirements, and target workstation specs to recommend the ideal desktop architecture.
Next-generation desktop architecture combining a native OS webview frontend with a blazing-fast, memory-safe Rust backend. Installers under 10 MB with minimal RAM consumption.
You require small installer sizes, sub-50MB RAM usage, deep Rust system-level security, instant boot times, or serial hardware integrations on standard business PCs.
Native backend logic is written in Rust, requiring specialized systems programming rigor rather than standard Node.js scripts.
Battle-tested desktop framework bundling Chromium and Node.js. Guaranteed 100% identical browser rendering across legacy operating systems and deep compatibility with npm native C++ addons.
Your software depends on complex Node.js C++ addons with no Rust counterpart, you are maintaining an existing large Electron codebase, or targeting older legacy machines.
Heavy ~120MB+ installer footprint and 300MB+ base memory overhead due to bundled Chromium browser binaries.
How We Work
Six disciplined steps from hardware architecture to signed installer.
Hardware & Systems Discovery
We audit your workstation hardware, target OS versions (Windows 10/11, macOS, Linux), peripheral communication protocols, and offline requirements.
Workstation UX & Keybindings
Counter and desktop software must be fast to operate. We design keyboard-first interfaces, numpad workflows, and high-contrast screens in Figma.
Native Backend & SQLite Engine
Implementation of Rust/Node native IPC bridges, local embedded SQLite database schemas, indexing for millisecond lookups, and file system isolation.
Hardware Driver Integration
Direct connection to USB, serial, and network printers (ESC/POS), barcode scanners, cash drawers, and biometric readers, tested against real physical hardware.
Code Signing & CI/CD Packaging
Automated building of signed Windows `.msi`/`.exe` with Authenticode and macOS `.dmg` with Apple Developer Notarization to prevent OS security warnings.
90-Day Telemetry & Retainers
Crash reporting, memory leak profiling, Windows/macOS OS upgrade compatibility checks, and seamless background patch distribution.
Desktop Capabilities Included in Every Build
Engagement Models
