A few months ago, our team kept running into the same annoying problem during development and QA:
We needed to test barcode scanner workflows, but physical scanner hardware was not always available.
- Sometimes the scanner was on another desk.
- Sometimes someone else was using it.
- Sometimes we needed to test quickly on macOS or Linux machines where our existing tooling did not work.
So I decided to build a small utility for myself.
That side project eventually became a full cross-platform desktop application with its own website, release pipeline, and download system.
What the tool does
The application simulates barcode scanner input by injecting keyboard input into the currently focused application.
You can:
- Enter barcode content
- Configure typing speed
- Add ENTER suffix behavior
- Assign a global keyboard shortcut
- Trigger barcode input instantly
It behaves similarly to a HID keyboard wedge barcode scanner.
That means it works with:
- POS applications
- ERP systems
- Warehouse software
- Internal tools
- Browser apps
- Desktop apps
- Basically anything that accepts keyboard input
Why I built it
Originally we were using another barcode reader emulator internally, but it was Windows-only.
That became limiting because our environment includes:
- Windows users
- macOS users
- Linux users (including Ubuntu)
Testing scanner-based workflows without physical hardware became increasingly painful.
I wanted:
- a lightweight tool
- global shortcuts
- native desktop feel
- cross-platform support
- simple UX
- no complicated setup
Tech Stack
The desktop app is built with:
- Electron
- Vue
- Tailwind CSS
The website was built separately as a dedicated landing page focused on:
- documentation
- downloads
- SEO
- onboarding
- release distribution
I Also Used AI Heavily During Development
One interesting part of this project was how much AI accelerated the process.
I used AI tools for:
- landing page copywriting
- UI/UX ideation
- visual direction
- component iteration
- SEO improvements
- content structuring
- frontend implementation support
Not in a “generate everything magically” way, but more like an always-available brainstorming and implementation assistant.
As a solo developer, it genuinely changed the speed of iteration.
Some Interesting Challenges
Global keyboard shortcuts
One of the trickier parts was making global shortcuts behave consistently across operating systems.
Each platform behaves slightly differently when applications lose focus or when permissions are restricted.
Simulating realistic scanner behavior
Real barcode scanners do not always dump text instantly.
So I added configurable typing speed and optional ENTER suffix behavior to better mimic real devices during testing.
Building the landing page
Oddly enough, building the marketing website became almost as fun as building the app itself.
Developer tools are interesting because the UX challenge is different:
- developers want clarity
- they dislike marketing fluff
- they want screenshots immediately
- they want direct downloads
- they care about trust and simplicity
Designing for that audience was a fun experience.
The Website
I recently launched a dedicated website for the project:
http://barcodescanneremulator.dev/
The site includes:
- cross-platform downloads
- screenshots
- release management
- FAQs
- usage explanations
- technical landing pages
Open Source
The project is open source as well:

Example Use Cases
Some real-world scenarios where this tool is useful:
- QA testing without physical scanners
- POS workflow validation
- Warehouse software testing
- ERP integrations
- Demo environments
- Local development setups
- HID keyboard wedge simulations
Final Thoughts
This started as a tiny utility I built after work to solve an internal workflow problem.
It turned into:
- a polished desktop app
- an open-source project
- a landing page + distribution platform
- and honestly, a great playground for experimenting with AI-assisted development workflows
If you work with barcode-based systems, I’d genuinely love feedback from people using different setups or workflows.
Thanks for reading 🙂
