Feature Comparison
Postproxy
Unified API for Multiple Platforms
Postproxy provides a single API endpoint that simplifies the publishing process across various social media platforms. This eliminates the need for individual integrations, reducing complexity and streamlining workflows.
Automated Content Adaptation
The platform automatically transforms content to meet the unique requirements of each social media site. This includes handling format conversions, media limits, and compliance with platform-specific rules, ensuring that posts look their best everywhere.
Reliable Failure Handling
Postproxy is designed to manage operational failures gracefully. It incorporates automatic retries, rate limit handling, and clear state reporting, allowing users to understand what succeeded, what failed, and why—without manual intervention.
Scalable Publishing Infrastructure
Whether publishing ten posts or thousands, Postproxy maintains consistent logic throughout the process. This scalability ensures that as your needs grow, the solution remains robust and reliable, making it easier to handle increased content demands.
Proofapp
Visual Commenting
Proofapp's foundational feature allows users to click on any pixel of a captured website screenshot to leave a contextual comment. This eliminates the frustrating and ambiguous language often found in emails, such as "move the button to the top left, under the navigation." Feedback is pinned directly to the exact element in question, providing crystal-clear direction for designers and developers. The system supports threaded replies, enabling detailed discussion around each point until it is resolved, keeping all context intact within a single, organized dashboard.
Multi-Breakpoint Testing
Understanding that modern websites must be perfect across all devices, Proofapp automatically captures and presents screenshots of any submitted URL at both desktop and mobile viewports. This allows teams and clients to review the design, layout, and functionality across critical breakpoints simultaneously. Feedback can be left on either version, ensuring issues specific to mobile responsiveness or desktop presentation are caught and addressed visually, preventing costly post-launch fixes and ensuring a consistent user experience.
Secure, Account-Free Sharing
Proofapp facilitates seamless client collaboration by allowing project owners to generate secure, shareable links. These links can be sent directly to clients or stakeholders, who can then view the screenshots and provide comprehensive feedback without the friction of creating a user account. The links can also be set to expire for added security. This feature dramatically lowers the barrier to entry for collecting external feedback, making the review process as simple as sending a URL while maintaining professional control over the project.
Real-Time Collaboration & Integrations
The platform fosters a dynamic collaborative environment where team members can see comments and replies as they happen, eliminating the need for manual refresh and keeping everyone in sync. Coupled with real-time notifications, this ensures no feedback is missed. Furthermore, Proofapp integrates directly with tools like Slack, pushing updates and comments into team channels. This creates a connected workflow where visual feedback from Proofapp becomes a natural part of the existing communication ecosystem, further reducing context-switching and streamlining project management.

Proofapp
Freelancer Client Approvals
Freelancers can use Proofapp to present website designs or developments to clients in a professional, organized manner. Instead of exchanging dozens of emails with attached, annotated images, the freelancer shares a single Proofapp link. The client clicks directly on the design to leave precise feedback, which the freelancer can then address and mark as resolved. This process saves hours per project, reduces revision rounds by an average of 60%, and presents a polished, modern workflow that enhances client trust and satisfaction.
Agency Design Team Workflows
Within a design agency, internal teams and external clients are often involved in the review process. Proofapp serves as a central hub for all visual feedback. Designers can upload multiple page URLs for a full website review. Project managers, developers, and clients can all leave comments in one place. The ability to tag team members, attach reference files, and track the resolution status of each item transforms a chaotic process into a manageable, trackable workflow, ensuring nothing falls through the cracks before launch.
Marketing Campaign Landing Page Reviews
Marketing teams frequently need to review and approve high-stakes landing pages for campaigns with input from copywriters, designers, brand managers, and legal. Using Proofapp, the team can collect all visual and copy feedback directly on the live page mockup. This prevents miscommunication about which headline or image needs changing and accelerates the approval cycle. The visual context ensures that feedback on tone, placement, and compliance is accurate and actionable, helping campaigns launch faster and more effectively.
Development Bug Reporting & QA
Developers and QA testers can utilize Proofapp as a superior bug reporting tool. Instead of writing lengthy descriptions to explain a visual glitch or layout issue, testers can capture the page in Proofapp and pin a comment exactly where the problem occurs. They can attach console logs or other files to the comment. This provides developers with immediate, unambiguous context for every issue, drastically reducing the time spent deciphering bug reports and speeding up the resolution process.
