Kitsmith / Utilities / Rectangle
Free, open-source window snapping for macOS — keyboard shortcuts and drag-to-edge snap areas, built as a spiritual successor to the discontinued Spectacle app.
Our take
The default free pick for window management on Mac, and a near drop-in replacement for the discontinued Spectacle app — its license file credits Spectacle directly, and it offers Spectacle’s original shortcuts on first run. It’s genuinely free and open source with no ads or nags; Rectangle Pro is a separate paid upgrade ($9.99 after a 10-day trial) for quicker snapping and fully custom shortcuts, but the free version is a complete tool on its own, not a crippled demo.
