What Priflow is

Priflow is open-source proofing and approval software for designers, marketers and small agencies. Reviewers can click a point on an image or multi-page PDF to leave a numbered comment tied to that location. Teams can retain earlier versions as new ones are uploaded, tag teammates into proofs and track approvals or change requests. Clients can review through links without accounts; signing in is optional. Priflow logs uploads, amendments, replies and approvals with who performed each action and when. It is self-hosted on PHP 8 or later with MySQL, including shared hosting. The free plan costs nothing, billed forever, and includes unlimited users, proofs, reviewers and teams, plus every feature and update. Client files stay on the user's server, and the software is MIT-licensed for commercial use. The default upload limit is 50 MB. Community support is available through GitHub, and the maker offers paid setup help. The product does not claim automated compliance routing or enterprise SSO.
