Technical Deep Dive · HEROIC Desktop
Building a Windows security desktop prototype with Flutter, Go, osquery, and Inno Setup
This HEROIC desktop project was a non-distributed Windows security prototype. I built the experience around a Flutter desktop interface, a Go-based Windows agent, osquery-powered system data retrieval, and Inno Setup packaging so the app could behave like a desktop security product instead of a simple UI demo.
Product Goal
A desktop security companion that makes device health and risk visible
The idea was to build an antivirus-style HEROIC desktop app for Windows. The product needed to show a clear protection score, highlight concerns, record device activity, inspect system information, and surface security insights that a user could understand quickly.
Because this kind of app depends on real system state, Flutter alone was not enough. The desktop UI handled the product experience, while the Go agent worked closer to Windows and used osquery to retrieve device and system details.
Architecture
The product was split between a polished desktop shell and a system-aware Windows agent
Flutter Desktop
Dashboard, activity feed, system tabs, security insights, account, settings, and desktop navigation.
Go Windows Agent
Background system-side work for collecting and preparing device information outside the UI layer.
osquery
Used to retrieve device, software, storage, performance, and security-related system details.
Inno Setup
Combined the desktop application pieces into a Windows installer workflow for the prototype build.
What I Built
The app covered dashboard, system visibility, activity, insights, account, and settings flows
Protection score and concerns
Created the main overview showing protection score, CPU, memory, storage, concerns, and recent activity.
Filtered event timeline
Designed activity views for all, unread, security, and system events including sign-in, extension, update, and agent activity.
Live device inspection
Built system sections for overview, performance, hardware, software, storage, and network visibility.
Actionable insights
Structured security insights around concerns, browser extensions, USB activity, and account access signals.
Profile and HEROIC apps
Added account surfaces for profile state, subscription information, device status, and linked HEROIC apps.
Desktop preferences
Included notification preferences, app version information, update checks, help center, and privacy/terms access.
Challenges & Resolutions
The important challenge was connecting desktop UX with real Windows system behavior
Challenge 01
Flutter UI alone could not retrieve the required system-level data.
A desktop security product needs device, software, storage, performance, and security information from Windows. That work belongs closer to the operating system than the UI layer.
How I resolved it
I separated responsibilities: Flutter handled the product interface, while a Go Windows agent worked as the system-side component and used osquery to retrieve the required details.
What improvedThe app could present real device context while keeping the UI focused on clarity, navigation, and user decision-making.
Challenge 02
The product needed security information without overwhelming the user.
Raw system data is not useful by itself. The experience needed to translate telemetry into dashboard signals, concerns, system sections, and insight cards.
How I resolved it
I organized the app around understandable areas: protection score, recent activity, system tabs, storage usage, software inventory, performance data, and security insights.
What improvedThe prototype became easier to read because the user could move from a high-level protection score into the specific system or security detail that needed attention.
Challenge 03
The app needed to feel like a Windows product, not only a Flutter screen.
Desktop security apps need a proper installable shape, predictable navigation, and settings/account flows that match a utility product.
How I resolved it
I combined Flutter desktop, the Go agent, and Inno Setup packaging so the prototype could be installed and reviewed as a Windows desktop product.
What improvedThe project moved closer to a real desktop app workflow with installer packaging, app settings, account screens, and a system-aware dashboard.
