Comparing options? See the Filestage alternative guide — Filestage is the closest Ziflow competitor, or the best video review software across all categories.
Ziflow is built for compliance teams managing audit trails — not for creative video production. It handles file reviews, but has no production stages, storyboard tools, or video-specific workflows. You end up managing everything else in separate tools.
Krock.io is built specifically for video teams. Social content, UGC, animation, commercials — review, approvals, and production workflow all in one place, from first storyboard to final delivery.
Ziflow’s Standard plan runs $249/month for 15 users with 1TB storage ($199/month annual). Capterra reviewers consistently flag it as overpriced for what it delivers.
Krock.io is $10/seat with 2TB storage — double the space at a fraction of the cost. Or go Unlimited: one fixed monthly price, no user caps. A 3-person UGC team or 25-person agency pays the same predictable rate. See the full pricing comparison.
Ziflow approves files. It doesn’t manage production — no stage dependencies, timelines, or milestone tracking. Knowing what’s blocked, what’s next, or where a 30-clip UGC batch stands? That happens in a separate tool, creating exactly the fragmentation you were trying to avoid.
Krock.io builds production stages natively. Brief → Shoot → Edit → Review → Final. Each stage has due dates, owners, and dependencies. One platform tracks the whole production.
Ziflow’s compliance-first design creates overhead for fast-moving creative teams. Reviewers flag navigation friction and clunky file replacement mid-review — real time costs when you’re running three feedback rounds a day.
Krock.io is built for speed. Timestamped frame-level comments, one-click approvals, no account needed for clients. Most teams send it to clients cold — no training required.
Ziflow’s notifications flood inboxes — every comment, every update, every stage change triggers an email. Users find the settings unwieldy. When people start ignoring the emails, deadline alerts become useless.
Krock.io keeps it focused: assignees get notified on mentions and assignments, clients get a clean review link, deadlines sync to Google Calendar and Outlook. Signal, not noise. See how notifications work.

Intuitive UI for new users and clients
Sync review comments directly with your Premiere Pro timeline. No more switching tabs—feedback appears exactly where you need it, speeding up your edit-to-approval cycle.
Connect Krock.io to Final Cut Pro for seamless round-tripping between edit and review. Your team comments on versions while you keep cutting—without export bottlenecks.
Bring client feedback into your DaVinci Resolve workflow. Colorists and editors see time-coded notes without leaving their grading session, keeping revisions tight and deadlines intact.
Get instant notifications when clients approve, comment, or request changes. Your team stays in the loop without inbox overload—review updates land in the channels that matter.
Push motion graphics to review and pull comments back into After Effects. Animators get frame-accurate feedback while clients get a simple way to mark exactly what needs fixing.
Yes. Krock.io supports video files, images, PDFs, and audio files for frame-accurate review and annotation. It also adds production-specific formats — storyboard frames, animatics, multi-track audio — that Ziflow doesn't support. See the full supported file formats list, or the detailed guide on what file types you can upload and review in Krock.io.
