Ziflow provides online proofing for creative teams, but it's often cited as complex to set up and expensive to scale. Synks offers the same proofing capabilities with a simpler interface, broader file type support, and pricing that doesn't penalize you for adding reviewers. Every plan includes unlimited guest reviewers at no extra cost.
Unlimited reviewers on every plan. Ziflow charges per user.
Review websites, 3D models, and audio files — not just images and PDFs.
Share a link, start reviewing. No complex workspace configuration.
Gantt charts, time tracking, and invoices included.
