Show HN: Kiln – a fast, native batch image processor

the-hangry-dev1 pts0 comments

I was tired of outdated UIs and performance of similar tools. Nor did I want to write ImageMagick scripts every time I needed to resize/convert/watermark a folder with a few thousand images.It s a native desktop app built with C++23, Skia for rendering, libvips for image processing and my own cross-platform UI toolkit - no Electron/Qt.It allows building reusable pipelines: resize, convert, compress, watermark, sharpen, blur, rotate, flip, rename, and metadata (EXIF/IPTC/XMP) editing, chained in any order and saved for reuse. Batches run in parallel.Everything is local — no uploads, no signups/account, no telemetry, no network calls during processing.It s currently in public beta (as mentioned, no signups or accounts needed - can just download), for Windows and Linux (Wayland only). Waiting for the Apple certificate to sign the macOS dmg installer, at which point I ll post the download link for macOS.Business model: free beta now, one I ve received enough feedback and the tool is mature enough - a one-time license per major version once it s out of beta. There won t be any subscriptions or telemetry ever.Would love to get your feedback, especially on missing formats/operations (e.g. RAW file formats, watch folders, a CLI) to drive the roadmap to the first official version.Cheers.
