Feature Comparison
Proofapp
Visual Commenting & Annotation
This foundational feature allows any reviewer to click directly on a live screenshot of the website to leave a contextual comment. This action pins a visual marker to the exact element, whether it's a button, image, or text block, eliminating all ambiguity about location. Feedback threads can be created where team members can reply, discuss, and attach supporting files, ensuring every piece of input is tied directly to its visual context and remains organized within the platform's dashboard.
Multi-Breakpoint Screenshot Capture
Proofapp automates the tedious process of capturing website states by instantly generating screenshots for both desktop and mobile views upon project creation. This ensures that feedback accounts for responsive design from the very first review. Teams can toggle between these breakpoints to see how elements render on different devices, allowing for comprehensive feedback that covers the full user experience without manual screenshotting or resizing browser windows.
Secure, Account-Free Client Sharing
Facilitating seamless client collaboration, Proofapp enables project owners to generate secure, shareable links. The significant advantage is that clients or external stakeholders can view the project and leave detailed, pinned feedback without the friction of creating a user account. These links can be set to expire for added security, making it incredibly easy to gather input from anyone, regardless of their technical proficiency or willingness to sign up for another service.
Real-Time Collaboration & Notification
The platform operates in real-time, meaning when a comment is pinned or resolved, all project members can see the update instantly without refreshing the page. This creates a live collaborative environment akin to working in a shared document. Coupled with integrated notifications and Slack connectivity, teams stay perfectly synchronized, dramatically reducing the "waiting" period in feedback loops and ensuring everyone is always aligned on the latest changes and decisions.
Refbox
Floating Reference Frames
Refbox allows users to create floating reference frames that can be resized and positioned anywhere on their screen. This feature ensures that your references are always visible, regardless of the application you are using, enhancing your productivity.
Masonry Mode
The Masonry Mode organizes your pinned content into visually appealing layouts, making it easier to view multiple references at once. This feature is perfect for moodboarding and ensures that your creative inspirations are presented in an aesthetically pleasing manner.
Markdown-Enabled Notes
With markdown-enabled notes, users can jot down ideas, create checklists, and include styled text without needing to switch between apps. This integration keeps your thoughts organized and accessible right alongside your visual references.
GIF Playback and Pixel Rendering
Refbox supports GIF playback, allowing users to step through each frame for detailed analysis. Additionally, the pixel rendering feature ensures that pixel art is displayed correctly, providing artists with the precision they need for their projects.
Use Cases
Proofapp
Freelancer-Client Website Approvals
Freelancers can use Proofapp to present website drafts to clients in a professional, organized manner. Instead of exchanging dozens of emails with attached, annotated images, the freelancer shares a single link. The client clicks directly on the site to leave clear, visual notes, which the freelancer can then address and mark as resolved. This streamlines the revision process, reduces miscommunication, and presents a polished, efficient workflow that enhances client trust and satisfaction.
In-House Design & Development Team Sprints
For product teams running agile sprints, Proofapp serves as the central review tool for new features and UI changes. Designers can upload mockup URLs, and developers and product managers can provide specific technical and UX feedback directly on the design. This visual collaboration ensures that everyone—from UX to QA—has a unified understanding of requirements and issues, leading to fewer misinterpretations and faster iteration cycles during critical sprint reviews.
Marketing Campaign Landing Page Reviews
Marketing teams tasked with launching campaign-specific landing pages can leverage Proofapp for cross-departmental reviews. Colleagues from copywriting, design, legal, and leadership can all access the same secure link to provide feedback on content, compliance, branding, and call-to-action placement. Having all comments visually pinned on the page consolidates disparate inputs into one actionable list, ensuring the final page is optimized and approved by all stakeholders before going live.
Agency Managing Multiple Client Projects
Digital agencies juggling multiple client projects simultaneously benefit from Proofapp's project organization and client-friendly interface. Each client project is kept separate and secure. Project managers can track feedback progress, see resolved items, and maintain a clear audit trail of all communications. This eliminates the risk of mixing client feedback and provides a scalable, professional system for delivering and receiving revisions, improving overall agency efficiency and client retention.

What website breakpoints does Proofapp capture?
Upon creating a project with a website URL, Proofapp automatically captures two essential breakpoints by default: a standard desktop view and a mobile view.
