A fast, native clipboard manager for Windows — built in C++ with Qt 6.

ClipStream remembers everything you copy — text and images — and brings it back instantly with a global hotkey, full-text search, and one-keystroke paste.

Note: ClipStream was originally built with Tauri (Rust + Preact). It has been rebuilt from the ground up in C++/Qt 6 for a smaller, faster, fully native app. The original implementation lives on the legacy branch.

• Event-driven capture — listens to the OS clipboard, no polling, ~0% idle CPU
• Global hotkey — Ctrl+Shift+V opens the overlay anywhere, at your cursor
• Full-text search — instant SQLite FTS5 search across your history
• Text & images — images stored as files on disk (not bloating the database)
• Smart actions — open URLs, reveal files, convert colours, evaluate maths
• Format on paste — paste as UPPER / lower / Title / trimmed
• Quick paste — Ctrl+1–9 to paste the Nth clip instantly
• Snippets — save reusable text (Ctrl+N), kept pinned at the top
• Source tracking — shows which app each clip came from
• Privacy first — masks detected secrets, excludes password managers, pause toggle
• Themes — System / Dark / Light
• Lightweight & native — ~39 MB bundle, single-file installer ~13 MB

Download the latest installer from Releases, or build from source below.

• Language: C++17
• UI: Qt 6 Widgets (frameless translucent overlay, model/view, custom delegate)
• Storage: SQLite + FTS5 via Qt SQL
• Platform: Win32 (RegisterHotKey, SendInput, GetForegroundWindow) behind a cross-platform abstraction (Linux/macOS stubs ready to implement)
• Build: CMake + Ninja (MinGW); packaged with windeployqt + Inno Setup

Requires Qt 6 (MinGW kit), CMake, and Ninja.

# Configure (Release, Ninja)
cmake -S . -B build -G Ninja -DCMAKE_BUILD_TYPE=Release `
  -DCMAKE_PREFIX_PATH="C:/Qt/6.11.1/mingw_64"

# Build
cmake --build build

# Bundle the Qt runtime to run anywhere
windeployqt --release --no-translations dist\ClipStream\ClipStream.exe

CI builds and packages an installer on every push (see .github/workflows/build.yml).
