About Redlamp

Redlamp is a native RAW photo editor for Apple Silicon Macs (macOS 26+), built in Swift and Metal around a Lightroom-style Develop workflow with the same panel layout, slider names and shortcuts. It offers masking with on-device AI masks, healing and removal, focus stacking, lens corrections, film simulations and presets, and it saves edits in sidecar files next to your photos. It is free, with no account and no cloud; AI runs on your Mac, and models download on first use. Caveats: it is alpha software (v0.3.3), Mac-only for now (iPad and iPhone are planned), and most commits are co-authored by an AI coding agent. It can use Adobe camera profiles you already have from Lightroom Classic or Camera Raw, but ships none. The app checks for updates (Sparkle) and fetches What's New notes from redlamp.app. Bug reports you send are posted publicly as GitHub issues.
