Flatproof vs Ziflow

Flatproof is web-based proofing software for client approvals. It handles images, PDFs, videos, audio, live websites, Figma links, presentations, and other uploaded files. A user can upload or import a proof, share one link, gather comments, manage versions, and record approvals. Clients and reviewers can comment and approve through that link without becoming paid seats. Annotation tools, approval workflow, version history, and guest reviewers are included. AI review inspects selected areas and creates private draft suggestions that the user may turn into feedback. Google Drive and Figma integrations are shown for importing source files or frames. Flatproof has a free plan with 200MB storage and 25MB uploads, plus unlimited creators and reviewers. Solo costs $5 a month with 100GB storage; Studio costs $29 a month with 1TB storage and bring-your-own AI key. The product is in beta, so bugs and interruptions may occur.

Ziflow is an online proofing platform for creative review and approval workflows. Teams can review design files, videos, live websites, and other campaign assets. ReviewAI checks checklist items and brand standards while reviewers retain control over decisions. The platform supports more than 1,200 file types and single-file uploads up to 5TB. It integrates with tools including monday.com, Dropbox, Slack, Asana, Adobe Creative Cloud, Jira, Microsoft Teams, Google Drive, Figma, and Salesforce. A RESTful API can extend workflows to proprietary applications and other platforms. Ziflow works in a browser without requiring an app: desktop Chrome, Firefox, and Edge are supported, as are Chrome on Android and Chrome or Safari on iOS. A browser extension is recommended for rich media and live website proofs. The free plan includes 2 users, 2GB storage, 1 workflow stage, and 60 days of review history. Standard costs $199 a month billed annually; Pro costs $329 a month billed annually.
