Feature Comparison
Proofapp
Visual Commenting
This is the heart of Proofapp. Instead of describing changes in lengthy emails, reviewers simply click on any part of the captured website screenshot to leave a comment. This pins the feedback directly to the exact pixel, eliminating confusing instructions like "move the button a bit to the left, under the header." Comments support rich threads, allowing for back-and-forth discussion directly on the design element in question, ensuring perfect clarity and context for every piece of feedback.
Multi-Breakpoint Testing
Proofapp understands modern web design requires a responsive approach. When you submit a URL, it automatically generates screenshots for both desktop and mobile views in one go. This allows teams and clients to review the user experience across critical breakpoints simultaneously, catching layout or functionality issues specific to each device without needing to manually resize browsers or take separate screenshots.
Secure, Account-Free Sharing
Streamlining client collaboration is a priority. With Proofapp, you can share a review project by generating a secure, shareable link. The powerful feature is that your clients or external stakeholders do not need to create an account or log in to view the screenshots and leave comments. This drastically reduces friction in the feedback collection process, making it as easy as sending a link, while you maintain control over project access.
Real-Time Collaboration & Resolution
Feedback becomes a live conversation. Team members and clients see new comments and replies appear in real-time, fostering a dynamic collaborative environment. Each comment can be marked as "resolved" once the feedback has been addressed, providing a clear, visual progress tracker for the entire project. This feature turns a static list of notes into an actionable workflow, ensuring nothing falls through the cracks.
Refbox
Floating Reference Frames
Refbox offers floating frames that stay on top of all other applications, providing instant access to your references without disrupting your workflow. You can resize these frames to fit your needs, ensuring that your workspace remains clutter-free while all your essential media is always within reach.
Infinite Canvas
The infinite canvas feature allows users to view all their media at once, flipping through items like a slideshow for quick comparisons. This capability makes it easy to assess multiple references simultaneously, streamlining the creative process and facilitating better decision-making.
Auto-Hide Functionality
Refbox includes an auto-hide option that lets you minimize distractions by hiding the floating frames until you need them. This feature ensures that your references are only visible when required, allowing you to maintain focus on your creative tasks without unnecessary interruptions.
Customizable Shortcuts
With customizable shortcuts, Refbox gives users complete control over their references. You can quickly swap out floating references, change collections, or lock frames, making it easier to manage your resources efficiently and enhancing your overall productivity.
Use Cases
Proofapp
Freelancer-Client Website Approvals
Freelancers and independent contractors can use Proofapp to present website drafts to clients professionally. Instead of exchanging dozens of emails with attached, annotated images, they share a single Proofapp link. Clients click to give precise visual feedback, which the freelancer can then address and mark as resolved. This use case saves hours per project, reduces miscommunication, and presents a polished, efficient workflow that enhances client trust and satisfaction.
In-House Design & Development Handoff
Internal teams can streamline the handoff process between designers and developers. A designer can upload a live prototype or staging site URL to Proofapp. Developers can then click directly on elements to ask specific implementation questions, report bugs visually, or confirm design specs, all within the context of the design itself. This visual thread creates a clear audit trail and reduces back-and-forth in chat apps.
Marketing Team Landing Page Reviews
Marketing teams often need collective input on campaign landing pages from copywriters, designers, and managers. Proofapp allows the entire team to collaborate on a single page simultaneously. Stakeholders can pin comments on headlines, call-to-action buttons, or form fields, ensuring all feedback is consolidated visually in one place, speeding up the revision process before the page goes live.
Agency Managing Multiple Client Projects
Digital agencies managing several client websites can use Proofapp as a centralized feedback hub for all projects. They can organize reviews by client or project, using the platform's dashboard to track open and resolved comments across all active work. The account-free sharing for clients simplifies their process, while the agency benefits from a standardized, professional review system that scales with their workload.
