Show HN: ClipCapsule – A Clipboard Manager for Linux (Built with Go and Wails)

2 months ago 2

ClipCapsule is a minimalist clipboard manager for Linux, built with Go and WailsJS. It supercharges your productivity by allowing you to manage and switch clipboard entries using only keyboard shortcuts—no mouse or GUI required.

⚠️ This is a work-in-progress project. Currently, the GUI must be open for shortcuts to work, but we're actively working on a background daemon to make the app run seamlessly without launching the interface.


  • 🚀 Keyboard-first Workflow: Switch clipboard items instantly with CTRL + SHIFT + 1~9.
  • 📜 Clipboard History: Automatically saves your recent copies in an embedded database.
  • 🔄 Dynamic Reordering: Selecting an item with a shortcut moves it to the top of the stack.
  • 🔐 Local-Only: Your data stays on your machine, no cloud syncing or telemetry.

When you copy items, the database stores them like this:

text pos
item1text 1
item2text 2
item3text 3
item4text 4
item5text 5
... ...
  • The item at pos = 1 is the active clipboard item (what gets pasted on CTRL + V).
  • Pressing CTRL + SHIFT + 3:
    • Moves item3text to position 1.
    • Reorders the rest accordingly.

git clone https://github.com/Victor-Evogor/clipcapsule.git cd clipcapsule

Follow instructions from the Wails documentation.

You'll need to build with elevated privileges to allow the app to listen for global key events:

🛑 Alternatively, give your user access to the keyboard input device path (e.g. /dev/input/eventX) by adding appropriate udev rules or group permissions.

Example (for testing):

sudo chmod a+r /dev/input/eventX

(Replace /dev/input/eventX with your actual keyboard event device.)

⚠️ A proper fix for permissions will be added soon. For now, elevated privileges or manual access setup is required.


Shortcut Action
CTRL + V Paste current top clipboard entry
CTRL + SHIFT + 1-9 Move selected item to the top of the stack

  • Frontend: Wails + JS/TS (see runtime/)
  • Backend: Go (see go/main/)
  • Clipboard access and keyboard interception handled natively


  • Core clipboard logic
  • Keyboard shortcut mapping
  • Daemon mode (run in background without GUI)
  • Tray icon & preferences
  • Configurable shortcuts
  • Clipboard preview UI
  • Exclude sensitive entries (e.g., passwords)

  • You need to run the app as sudo or manually allow access to keyboard input devices.
  • No daemon yet — GUI must be open for shortcuts to work.
