Premium proofing platforms charge hundreds per user, per month for what small teams actually need: pin-point feedback on artwork & PDFs, guest review links, versioning and clean sign-off. Priflow gives you all of it — open source, self-hosted, yours forever.
PHP + MySQL · no build step · runs happily on a $5/mo shared host
Built for designers, marketers and small agencies who need fast, unambiguous feedback — not another subscription.
Click anywhere on an image or PDF to drop a numbered comment exactly where the change is needed — no more “the logo, top-left-ish”.
Upload v2, v3 as the work evolves. Everyone sees the latest by default, and earlier versions stay on record.
Share a link and reviewers jump straight in as guests — or sign in to be recognised. Zero friction for clients.
Each reviewer gives Approve or Request changes. The proof’s status rolls up automatically — no ambiguity.
Accounts with dashboards, tag teammates into proofs, and see what’s yours and what you’ve been pulled into.
Every upload, amend, reply and approval is logged with who and when — so sign-off is never in dispute.
No software for reviewers to install. No accounts required to give feedback.
Drop in your artwork or multi-page PDFs and create a proof in seconds.
Send the review link to anyone — clients, colleagues, stakeholders.
Collect pinned amends, reply, resolve, and get a clean, logged approval.
Proofing platforms are priced for enterprises. Small studios end up funding features they'll never open.
