Batch Lightframe Inspection & Preview: a minimal, fast FITS and XISF blinker for astro images, hardware-accelerated on the GPU.
Download the Windows installer (or the portable .zip, which needs no setup), the macOS disk
image, or the Linux Flatpak (x86_64 or aarch64) or .tar.gz from the
releases. Install the Flatpak with
flatpak install --user blip-<version>-linux-<arch>.flatpak.
To build from source you need Rust 1.95 or newer (the MSVC toolchain on Windows).
