## Docs

- [ShareClick vs. alternatives](https://shareclick.mintlify.app/compare/overview.md): How ShareClick compares to Synergy, ShareMouse, Barrier, Input Leap, Mouse Without Borders and Apple Universal Control.
- [ShareClick vs Barrier](https://shareclick.mintlify.app/compare/vs-barrier.md): Barrier is no longer maintained. ShareClick is a modern, actively developed successor — encrypted by default, with clipboard images, file transfer and zero-config discovery.
- [ShareClick vs Input Leap](https://shareclick.mintlify.app/compare/vs-input-leap.md): A free, open-source Input Leap alternative: encrypted by default, clipboard images, file transfer and mDNS discovery for Mac and Windows.
- [ShareClick vs Mouse Without Borders](https://shareclick.mintlify.app/compare/vs-mouse-without-borders.md): A free, open-source alternative to Mouse Without Borders that also works on Mac. Share mouse, keyboard, clipboard and files between Mac and Windows. Encrypted.
- [ShareClick vs ShareMouse](https://shareclick.mintlify.app/compare/vs-sharemouse.md): A free, open-source ShareMouse alternative to share mouse, keyboard, clipboard and files between Mac and Windows. Encrypted, low-latency.
- [ShareClick vs Synergy](https://shareclick.mintlify.app/compare/vs-synergy.md): A free, open-source Synergy alternative to share mouse, keyboard, clipboard and files between Mac and Windows. Encrypted, low-latency.
- [ShareClick vs Universal Control](https://shareclick.mintlify.app/compare/vs-universal-control.md): Like Apple Universal Control, but across Mac and Windows. Share one keyboard, mouse, clipboard and files between a Mac and a Windows PC. Free, open source, encrypted.
- [Architecture](https://shareclick.mintlify.app/concepts/architecture.md): ShareClick's dual-channel design: UDP for low-latency input, TCP for reliable clipboard and files — and how a keypress reaches the other machine.
- [Latency](https://shareclick.mintlify.app/concepts/latency.md): Where the microseconds actually go — ShareClick's ~6 µs one-way transport overhead and the design decisions that keep input lag minimal.
- [Wire protocol](https://shareclick.mintlify.app/concepts/protocol.md): ShareClick's two-channel wire format: postcard-encoded input packets over UDP and length-prefixed bulk messages over TCP.
- [Security & cryptography](https://shareclick.mintlify.app/concepts/security.md): ShareClick's WireGuard/Noise-inspired crypto: ephemeral X25519, a pre-shared passphrase, HKDF-SHA256 and ChaCha20-Poly1305 on every channel.
- [Configuration](https://shareclick.mintlify.app/configuration.md): Every field in config.toml — settings and the monitor-manager layout that ShareClick uses to route your cursor between machines.
- [Decision log](https://shareclick.mintlify.app/develop/decisions.md): Lightweight architecture decision records (ADRs) — the settled 'why' behind ShareClick's design, so future changes don't re-litigate them.
- [Development guide](https://shareclick.mintlify.app/develop/development.md): Build ShareClick from source, run the headless test suite, and contribute features while keeping the low-latency hot path clean.
- [Releasing](https://shareclick.mintlify.app/develop/releasing.md): The exact, repeatable process to ship a new ShareClick version — SemVer policy, the release checklist, and what CI builds.
- [Download ShareClick](https://shareclick.mintlify.app/download.md): Download the latest ShareClick for macOS and Windows — free and open source. One keyboard, mouse, clipboard and files across your machines.
- [File transfer](https://shareclick.mintlify.app/file-transfer.md): Send files between your machines over ShareClick's reliable, chunked, resumable-by-offset transfer channel.
- [Installation](https://shareclick.mintlify.app/installation.md): Install ShareClick on macOS and Windows, and get past the one-time unsigned-app warning.
- [ShareClick](https://shareclick.mintlify.app/introduction.md): A low-latency, open-source software KVM — move one keyboard, mouse, clipboard and files between macOS and Windows over your LAN, end-to-end encrypted.
- [Quickstart](https://shareclick.mintlify.app/quickstart.md): Share your keyboard, mouse, clipboard and files between macOS and Windows in about 60 seconds.
- [Troubleshooting](https://shareclick.mintlify.app/troubleshooting.md): Fixes for the most common ShareClick setup issues — permissions, authentication, connection and edge-switching problems.
- [Using ShareClick](https://shareclick.mintlify.app/usage.md): Share your keyboard, mouse, clipboard and files once ShareClick is installed on both machines — via the app UI or the terminal.
