What Priflow is
Priflow is open-source proofing and approval software for designers, marketers and small agencies. Reviewers can click a spot on an image or PDF to attach a numbered comment, and the workflow supports artwork and multi-page PDFs. Teams can retain successive versions, tag colleagues into proofs and follow approvals or requests for changes as proof status updates. Clients can review through links without accounts, while signing in is optional. Priflow logs uploads, amendments, replies and approvals with the person responsible and the time. It is self-hosted on PHP 8 or later with MySQL, including shared hosting; client files stay on the user's server, and the software is MIT-licensed for commercial use. The free plan is free, billed forever, and includes unlimited users, proofs, reviewers and teams, plus every feature and update. Community support is available on GitHub, and the maker offers paid setup help. The application's changelog documents a default upload limit of 50 MB.
