Feature Comparison

Proofapp

Visual Commenting

This foundational feature allows reviewers to click directly on any part of a captured website screenshot to leave precise, contextual feedback. This eliminates the frustrating and time-consuming back-and-forth of describing locations with words like "top left, under the nav." Comments are pinned visually, creating an unambiguous record of exactly what element is being discussed, which dramatically reduces revision cycles and ensures everyone is aligned from the very first comment.

Multi-Breakpoint Testing

Proofapp automatically captures and presents your website at both desktop and mobile breakpoints when you provide a URL. This critical feature ensures that feedback isn't limited to a single viewport, allowing teams to review and collaborate on the full user experience across devices. It streamlines the QA process, helping teams identify and resolve responsive design issues before launch, which is a key milestone in modern web development.

Real-time Collaboration & Notifications

The platform fosters a dynamic collaborative environment where team members and clients can see comments appear live. Coupled with instant notifications, this feature ensures the feedback loop is continuous and efficient. Users can reply within threads, attach supporting files, and resolve comments, tracking progress collectively without the need for manual status updates or refreshing the page, propelling projects forward smoothly.

Proofapp simplifies client involvement by allowing you to generate secure, expirable links to share projects. Clients can view screenshots and leave detailed feedback without the friction of creating an account, lowering the barrier to participation. This professional approach not only enhances security but also streamlines the client review process, making it a seamless part of your evolved project workflow.

Refbox

Always-on-Top Floating Frames

This foundational feature allows you to pin any reference—images, videos, GIFs, or notes—into individual frames that float above all other application windows. You can resize, reposition, and minimize these frames with ease, ensuring your key sources of inspiration are always visible as you sketch, design, or animate. This eliminates constant window-switching, a major workflow interruption, and keeps your focus locked on creation.

Masonry Mode & Desktop Canvas

Refbox offers a unique, organized sidebar that displays your references in a dynamic Masonry layout. From here, you can drag and drop items directly onto your desktop, creating a customizable, infinite canvas of inspiration. This mode is perfect for building mood boards, arranging storyboards, or simply keeping a collection of related visuals within easy reach and sight, all without leaving your creative environment.

Markdown-Enabled Notes & Checklists

Beyond visual media, Refbox integrates powerful note-taking directly into your reference ecosystem. Create notes with markdown support for styling, and even embed checklists for project to-dos or step-by-step instructions. This consolidates your workflow by removing the need for a separate note-taking app, keeping your creative briefs, ideas, and action items pinned right alongside your visual references.

Advanced Media Controls

Refbox provides deep control over your reference media. Scrub through videos and GIFs frame-by-frame for detailed study, perfect for animators and motion designers. Capture website screenshots by simply pasting a URL, crop images to focus on specific details, pick colors directly from any pinned media, and view SVG files as images. These professional-grade tools save hours of manual work in other applications.

Use Cases

Proofapp

Freelancer Client Approvals

Freelancers can present their web design or development work professionally using Proofapp. By sharing a secure link, they collect clear, visual feedback directly on the site mockup or live build. This eliminates confusing email chains, saves hours typically spent deciphering notes, and presents a polished, efficient process that builds client trust and accelerates project finalization.

Agency Project Management

Marketing and design agencies managing multiple client projects use Proofapp to centralize all feedback. It replaces disjointed communication across email, Slack, and documents with a single source of truth. Teams can manage feedback across various pages and breakpoints, assign tasks via comments, and maintain an audit trail, ensuring nothing is missed and projects stay on schedule.

In-House Design & Development Handoff

Internal product teams leverage Proofapp to bridge the gap between designers and developers. Designers can share interactive prototypes or live URLs, and developers can pin specific questions about functionality or implementation directly on the relevant element. This visual, contextual dialogue reduces misinterpretation during handoff, leading to fewer bugs and a more efficient development cycle.

Marketing Campaign Reviews

Marketing teams launching new landing pages or campaign microsites use Proofapp for collaborative review. Stakeholders from copy, design, and leadership can all leave targeted feedback on the same visual asset. This ensures all perspectives are captured visually and organized before development begins, leading to higher-quality launches and significantly fewer post-launch revisions.

Refbox

3D Modeling and Texturing

For 3D artists, maintaining visual consistency is crucial. Refbox allows you to pin reference images for textures, lighting, anatomy, and concept art directly over your 3D viewport. You can scrub through turntable videos frame-by-frame, pick colors from photos for materials, and keep modeling guidelines visible, all without ever leaving your modeling software, accelerating the entire sculpting and texturing process.

UI/UX Design and Development

Designers and developers can use Refbox to pin style guides, component libraries, and competitor screenshots for quick comparison. The floating frames ensure brand colors, spacing rules, and layout references are always in view while designing in Figma or coding in an IDE. Notes can hold hex codes and copy, while the gallery mode on a second monitor is perfect for reviewing full user flow mockups.

Digital Illustration and Concept Art

Illustrators and concept artists can build a dynamic mood board by dragging inspiration images directly onto their desktop canvas around their drawing software. They can lock a frame with a specific anatomical reference to draw over, use the color picker to sample palettes from photos, and keep narrative notes or client feedback pinned and visible throughout the entire sketching and painting phase.

Animation and Motion Graphics

Animators can pin sequential storyboard frames, character turnarounds, or video references in floating frames to study movement. The frame-by-frame scrubbing for GIFs and videos is indispensable for breaking down complex motions. Having these critical motion references always on top of the timeline in After Effects or Blender ensures accuracy and saves immense time otherwise spent switching back and forth.

Frequently Asked Questions

Proofapp FAQ

How do reviewers leave feedback without an account?

Reviewers do not need to create a Proofapp account to participate. The project owner simply generates a secure, shareable link from within their Proofapp dashboard and sends it to clients or stakeholders. Anyone with the link can view the captured screenshots and leave comments directly on the design, making the feedback process incredibly simple and frictionless for all parties involved.

Does Proofapp work on live websites or just mockups?

Proofapp works on any live, publicly accessible website URL. You paste the link, and the platform automatically captures screenshots. It is designed for reviewing live sites, staging environments, and prototypes. For static mockups or design files, you can often host them online or use the file attachment feature within a comment to provide context during a review.

Can I review multiple pages of a website?

Yes, Proofapp supports multi-page projects. You can add multiple URLs to a single project, allowing for comprehensive feedback across an entire website or a specific user flow. This is essential for agencies and product teams who need to manage feedback on entire sites, not just isolated landing pages, keeping all contextual notes organized in one place.

What happens after my free trial ends?

Proofapp offers a generous free tier with core functionality. After a trial of a paid plan, you will revert to the features and limits of the free plan. You can continue using the platform for smaller projects or upgrade to a paid plan to unlock additional capabilities like unlimited projects, priority support, and advanced security features to match your growing business needs.

Refbox FAQ

What types of files can I add to Refbox?

Refbox supports a wide range of media to fuel your creativity. You can directly add images (JPG, PNG, SVG, etc.), video files, and GIFs. You can also create text notes with markdown formatting. Additionally, you can import content by dragging from the web, your local file system, or even by pasting URLs to instantly capture website screenshots.

How does Refbox help with multi-monitor setups?

Refbox excels in multi-monitor environments. You can use the full-screen Gallery mode on a secondary monitor to display an entire collection of references like a digital mood board, leaving your primary screen completely free for your creative software. Floating frames can also be moved and resized across monitors, giving you flexible control over your reference placement.

Can I organize my references into different projects?

Yes, absolutely. Refbox allows you to create multiple, distinct Collections. You might have one collection for a client's branding project, another for a personal illustration, and another for tutorial resources. You can swap between these collections instantly with a single click or a keyboard shortcut, keeping your workspace organized and context-specific.

Is there a way to quickly hide Refbox when I don't need it?

Yes, Refbox is designed to be unobtrusive. You can set your main "Box" sidebar to auto-hide, so it only appears when you need to access your library. Individual floating frames can also be minimized to a small tab or managed with keyboard shortcuts, giving you full control to clear your screen and focus solely on your primary application when necessary.
