WinStack — Drag-and-Drop Windows App Installer With Auto-Update Management
Setting up a new Windows PC in 2026 still means clicking Next-Next-Finish forty times like it's 2009. WinStack lets you pick your apps from a curated library, hit Install All, and walk away — then charges $6/month to keep everything silently updated forever.

Windows users report spending 2-4 hours installing apps one-by-one on new PCs, with Ninite cited as helpful but limited — strong willingness to pay for a faster, more complete solution with auto-update management.
What is it?
Every developer, IT freelancer, and power user setting up a new Windows machine spends 2-4 hours hunting download pages and clicking through installers one by one. Ninite exists but covers only 100 apps, has no update management dashboard, and offers zero team features. WinStack solves this with a web UI where users select from 300+ apps, generate a one-click installer script, and optionally subscribe for silent background auto-updates via a tray agent. The $6/month personal tier and $15/seat team tier with device tracking is where the real money lives. Buildable now because winget (Windows Package Manager) is fully stable as of 2024 and covers 6,000+ packages — WinStack is purely a beautiful UI and scheduling layer on top of a free Microsoft API.
Why now?
winget reached stable v1.0 in 2023 and now covers 6,000+ packages — the infrastructure for a beautiful UI layer has existed for two years and nobody has shipped a polished SaaS on top of it yet.
- ▸Visual app selector with 300+ winget-backed apps across 12 categories (Implementation note: winget search API + curated JSON manifest)
- ▸One-click PowerShell installer script generator that runs silently without UAC prompts per app
- ▸Background auto-update tray agent (Windows service) that checks winget for outdated packages weekly
- ▸Team device dashboard showing installed app versions and update status per machine
Target Audience
Windows power users, IT freelancers managing 5-50 machines, and developers setting up new rigs — estimated 2M+ active Ninite users signal the market size.
Example Use Case
Marcus, an IT freelancer managing 30 client PCs, uses WinStack to deploy a standard 25-app stack to every new machine in 8 minutes instead of 2 hours, and pays $150/month for the team plan covering all his devices.
User Stories
- ▸As an IT freelancer, I want to generate a single installer script for my standard 25-app stack, so that I can set up any client PC in under 10 minutes.
- ▸As a power user, I want silent auto-updates for all my apps, so that I never manually check for updates again.
- ▸As a team manager, I want to see which apps are outdated across all my managed devices, so that I can patch security vulnerabilities before they become incidents.
Done When
- ✓Script generator: done when user selects 5+ apps and downloads a .ps1 file that installs all of them silently on a clean Windows 11 VM.
- ✓Auth: done when user clicks Google sign-in and their name appears in the top-right nav immediately after redirect.
- ✓Payment: done when Stripe checkout completes and the device dashboard tab becomes visible without page refresh.
- ✓Device dashboard: done when a registered device appears in the list with its installed app count within 60 seconds of the agent running.
Is it worth building?
$6/month personal × 500 users = $3k MRR. $15/seat × 10 IT freelancers × 10 seats avg = $1.5k MRR. Combined $4.5k MRR by month 4 is realistic via ProductHunt and r/sysadmin.
Unit Economics
CAC: $8 via Reddit organic. LTV: $144 (24 months at $6/month). Payback: 1 month. Gross margin: 88%.
Business Model
Freemium + SaaS subscription
Monetization Path
Free tier generates installer script only. Paid unlocks auto-update agent, device dashboard, and team seat management.
Revenue Timeline
First dollar: week 2 via beta upgrade. $1k MRR: month 2. $5k MRR: month 5.
Estimated Monthly Cost
Vercel: $20, Supabase: $25, Stripe fees: $50 at $1k MRR, Resend: $10. Total: ~$105/month at launch.
Profit Potential
Full-time viable at $8k-$20k MRR targeting IT freelancers and small MSPs.
Scalability
High — add macOS Homebrew support, enterprise SSO, and white-label for MSPs.
Success Metrics
Week 1: 500 script downloads. Month 1: 50 paid personal subscribers. Month 3: 5 team plan customers.
Launch & Validation Plan
Post generated installer script on r/sysadmin and r/windows as a free tool, measure downloads, then announce paid auto-update tier to that same audience.
Customer Acquisition Strategy
First customer: share a free WinStack script link in r/sysadmin and r/ITCareerQuestions — when commenters ask about auto-updates, pitch the $6/month tier directly. Ongoing: ProductHunt launch, YouTube tutorial targeting 'new PC setup' search, and Twitter/X dev community.
What's the competition?
Competition Level
Low
Similar Products
Ninite covers bulk install but no updates or teams. Chocolatey is CLI-only and targets developers not power users. WinGet UI is Microsoft's raw tool with no subscription layer or device tracking.
Competitive Advantage
Ninite has no auto-update dashboard, no team features, and no winget integration — WinStack covers all three with a modern UI.
Regulatory Risks
Low regulatory risk. GDPR applies if device telemetry is collected from EU users — anonymize device IDs and document data retention policy.
What's the roadmap?
Feature Roadmap
V1 (launch): app selector, script generator, Stripe personal plan, basic device list. V2 (month 2-3): team seats, auto-update agent, version diff alerts. V3 (month 4+): macOS Homebrew support, MSP white-label, Slack alerts.
Milestone Plan
Phase 1 (Week 1-2): app manifest, script generator, and landing page ship. Phase 2 (Week 3-4): Stripe billing, Supabase auth, and device dashboard live. Phase 3 (Month 2): tray agent shipped and first team plan sold.
How do you build it?
Tech Stack
Next.js, Supabase, Stripe, PowerShell script generator, winget CLI API — build with Cursor for backend script logic, v0 for app selector UI, Lovable for dashboard.
Suggested Frameworks
Next.js App Router, Supabase Auth, winget REST wrapper
Time to Ship
2 weeks
Required Skills
PowerShell/winget scripting, Next.js, Stripe billing, Supabase.
Resources
winget CLI docs, Microsoft Package Manager GitHub, Supabase quickstart, Stripe subscriptions guide.
MVP Scope
app/page.tsx (app selector grid + hero), app/api/generate-script/route.ts (winget script generator), app/api/webhook/route.ts (Stripe webhook), app/dashboard/page.tsx (device list), lib/winget-manifest.json (300 app definitions), lib/db/schema.ts (Drizzle schema), components/AppCard.tsx (selector card), components/DeviceRow.tsx (device status row), seed.ts (demo devices), .env.example (required vars).
Core User Journey
Select apps -> download installer script -> run on PC -> subscribe for auto-updates -> view device dashboard.
Architecture Pattern
User selects apps in UI -> JSON config saved to Supabase -> API generates PowerShell script -> script downloaded by user -> tray agent pings Supabase nightly -> winget runs update commands -> device status written back to dashboard.
Data Model
User has many Devices. Device has many InstalledApps. InstalledApp has one AppManifest. User has one Subscription.
Integration Points
winget CLI for package management, Stripe for subscriptions, Supabase for database and auth, Resend for onboarding emails, Vercel for hosting.
V1 Scope Boundaries
V1 excludes: macOS support, Linux, custom app upload, enterprise SSO, white-label, mobile app.
Success Definition
A paying IT freelancer manages 10 client devices through the dashboard without any founder help and renews after month one.
Challenges
Distribution is the hardest problem — IT freelancers are hard to reach and trust new tools slowly, so expect a 6-week sales cycle before the first team plan converts.
Avoid These Pitfalls
Do not build the tray agent before validating script-only demand — agent adds 2 weeks of complexity. Do not target enterprise IT (long sales cycles). Finding first 10 paying customers takes longer than building — spend week 1 on Reddit distribution not features.
Security Requirements
Supabase Auth with Google OAuth, RLS on all user and device tables, rate limit script generation to 20/hour per IP, validate all app IDs against manifest whitelist to prevent script injection.
Infrastructure Plan
Vercel for Next.js frontend and API routes, Supabase for Postgres and auth, GitHub Actions for CI on push to main, Sentry for error tracking, Vercel Analytics for traffic — estimated $55/month infrastructure.
Performance Targets
100 DAU at launch, script generation under 300ms, dashboard load under 1.5s, static app manifest served from CDN.

First Run Experience
On first run: 50 demo apps pre-loaded in the selector grid across 6 categories. User can immediately: select apps and download a working installer script without signing up. No manual config required: winget manifest is bundled, no API key needed for script generation.
How to build it, step by step
1. Define the winget app manifest JSON schema with id, name, category, and winget-id fields for 50 starter apps. 2. Run npx create-next-app winstack with TypeScript and Tailwind. 3. Build the AppCard grid UI using v0 with filter by category. 4. Create the script generator API route that maps selected app IDs to winget install commands. 5. Add Supabase Auth with Google OAuth and a devices table with Drizzle. 6. Build the device dashboard page showing app versions per machine. 7. Add Stripe subscriptions with a personal ($6) and team ($15/seat) plan. 8. Wire Stripe webhook to unlock auto-update features in Supabase. 9. Write the PowerShell tray agent script that reads a device token, calls Supabase, and runs winget upgrade. 10. Verify: select 5 apps, generate script, run on a fresh Windows VM, confirm all install, then check device appears in dashboard.
