Sealpixel keeps browser edits pixel-identical on the server
A source-available image-editing SDK that sends compact edit logs instead of originals, then renders matching full-resolution output on the server.
- For
- Developers building high-resolution image workflows
- Worth noticing
- A 556-byte edit log describes operations on an 80.1-megapixel original without sending that original to the browser.
Field notes
Sealpixel records crop, adjustment, redaction, filter, and resize operations as normalized edit-log data rather than transferring the source image for editing. The homepage shows a server render endpoint with S3 and inline source options, validation and size limits, deterministic job keys, and cached repeat requests. It also documents a Rust/WebAssembly core intended to run across browser and server environments, with framework examples and a plugin SDK.
