WebScreen is a hackable, open-source gadget for gamers, makers, and creators. It sits on top of your monitor like a webcam, keeping important notifications, reminders, and stats visible. With a vivid AMOLED display, an ESP32-S3 microcontroller, and a completely open hardware and software stack, WebScreen helps you focus while staying connected.

Stay in the Zone

WebScreen shows only the information you choose. No more switching to your phone or breaking concentration. Whether you are gaming, streaming, or working, WebScreen keeps you in the flow while making sure you do not miss critical alerts.

Hack It With JavaScript

Building for WebScreen is easy. Write your app in JavaScript, save it to a microSD card, and insert it into the device. It runs instantly. With Wi-Fi and Bluetooth built in, you can pull data from APIs, connect to smart home devices, or display system stats in real time. No special SDKs are required. WebScreen is a platform where simple code can create powerful tools.

We also wrote a Serial IDE were you can operate WebScreen with custom commands, and write Javascript apps without disconnecting and connecting the microSD card.

Open Source at Every Level

WebScreen is fully open-source. PCB schematics, firmware, enclosure design files, and documentation are all published under permissive licenses. This makes it easy to modify, remix, and improve the design. Backers are not just users, but also contributors. Transparency and community ownership are central to WebScreen.

WebScreen Marketplace

We are continuously building new apps, and our API makes it simple for anyone to create and share JavaScript applications, all stored on a microSD card. We are currently working on the WebScreen Marketplace, where you will be able to browse community-made apps, enclosure skins, and hardware mods, or upload your own. It will be available once the campaign is complete.

We Listened to the Community

Before launching WebScreen, we asked our community how they would use it. Through the subscribe form on our website, we collected dozens of ideas and requests from early supporters.

What we learned:

• Many people want notifications across platforms, such as Linux desktop alerts, Mattermost, Slack, WhatsApp, and Discord.
• Developers and hobbyists love that WebScreen is fully open-source and can be integrated into custom assistants, dashboards, and smart home systems.
• Customers are excited about how easy it is to build apps in JavaScript, save them to an SD card, and run them instantly.
• Popular use cases include productivity tools (Pomodoro timers, KPI dashboards, reminders), smart home integrations (Home Assistant, MQTT, APIs), and even creative extras like using WebScreen as a webcam light or a streaming companion.

Your feedback shaped WebScreen. We are building a tool that is open, hackable, affordable, and useful across many workflows.
