OptionFlow

Desktop apps that do what a browser tab can't.

We build native apps for Windows, macOS, and Linux — internal tools, hardware companions, and offline-critical products that need the filesystem, the hardware, or background work. Fast startup, deep OS integration, and signed installers your IT department approves.

Native OS Apps

What you get

  • PlatformsWindows, macOS, Linux
  • IntegrationFile system, hardware, OS APIs
  • DistributionSigned installers, auto-updates
  • OfflineLocal data, background sync
  • DeliveryTest builds every sprint

Sound familiar?

  • Your team runs a critical process from a spreadsheet and a folder of scripts

  • You ship hardware, and customers keep asking for a companion app that actually talks to it

  • Your web app is useless the moment the connection drops, and on site it drops daily

  • Your current desktop app eats memory, opens slowly, and feels like a website in a box

  • IT won't roll out your app because the installer isn't signed and fails on half the machines

  • Your desktop app runs on an unmaintained framework, and the one dev who knew it left

What we build

  1. 01

    Desktop apps for Windows, macOS & Linux

    Native apps with per-OS look, shortcuts, and behavior on a shared core — platform-native shells, not an Electron box that feels foreign everywhere.

  2. 02

    System integration

    Filesystem, USB and serial hardware, background services, notifications, OS APIs — including driver quirks, permission prompts, and sleep/wake failures a browser never faces.

  3. 03

    Installers, auto-updates & distribution

    Signed MSI, DMG with Apple notarization, Linux packages, silent installs for IT, and a non-breaking auto-update channel. You own the certs and the release pipeline.

  4. 04

    Performance & offline-first

    Offline-first local data, sync with explicit conflict rules and no silent loss, instant UI. Crash reporting included, so field failures come back with logs — not anecdotes.

How it works

  1. 01

    Discovery call

    Tell us what the app does, which platforms matter, and what it needs from the OS. We'll tell you if a web app is enough.

  2. 02

    Scope & proposal

    A fixed-scope plan with price, timeline, target platforms, and the first sprint mapped out — before any code is written.

  3. 03

    Build in sprints

    Signed test builds for each platform every one to two weeks, so you can install them, click around, and redirect us early.

  4. 04

    Launch & support

    Release builds, update channel, crash reporting, and documentation, plus a support window so the first rollout is uneventful.

Technologies we use

  • C#
