🌍 Building the Chrome Extension
The Chrome extension lives in web/ and is built via Gradle. Node.js (>= 18) is required — the npmInstall task will fetch dependencies on first build.
Build the extension
./gradlew :web:build
The unpacked extension is emitted to web/dist/.
Load it into Chrome
Open chrome://extensions/
Enable Developer mode in the top-right corner
Click Load unpacked and select the web/dist/ directory
The extension auto-discovers a CrossPaste desktop app running on the same machine and syncs clipboard content with it. To iterate on extension code, run npm run dev inside web/ for a fast Vite dev loop, then reload the extension in Chrome. The extension imports a Kotlin/JS core library produced by ./gradlew :core:jsBrowserProductionLibraryDistribution (also run as part of :web:build) — re-run that task whenever you change core/ sources.
🗺️ Roadmap
CrossPaste is continuously evolving! v2.2 brings a full command-line mode — copy, paste, and search your history straight from the terminal. Here's what we're working on next:
Plugin system — let the community extend CrossPaste with custom paste types and integrations
This is just a small part of our plans. Want to learn more details and long-term plans? Check out our full roadmap.
