Postproxy vs Proofapp

Unified API

The unified API provided by Postproxy allows users to publish content across multiple social media platforms with a single request. This eliminates the need to manage separate integrations, simplifying the publishing process and reducing development time.

Automatic Content Adaptation

Postproxy automatically transforms content to meet the specific requirements of each platform, including format conversion and compliance with media limits. This ensures that posts appear correctly regardless of where they are published, saving time and reducing errors.

Enhanced Delivery Guarantees

With built-in delivery guarantees, Postproxy manages retries, rate limits, and quota awareness, ensuring that your content is published reliably. Users receive clear reporting on the state of each publish request, which helps in monitoring performance and addressing any issues.

Simplified Authentication Management

Postproxy streamlines the authentication process by handling OAuth flows, token storage, and automatic refreshes. This means users do not have to worry about manually managing access tokens or dealing with platform-specific authentication hurdles.

Visual Commenting

This is the foundational feature of Proofapp. Instead of describing issues with words, reviewers can click directly on any part of the captured website screenshot to leave a comment. This action pins the feedback visually to the exact pixel location, eliminating all ambiguity. Team members can then reply within threaded conversations directly on that pin, attach supporting files, and mark comments as resolved once the feedback has been addressed. This creates a clear, actionable, and organized record of all project feedback in one central location.

Multi-Breakpoint Testing

Proofapp understands that modern websites must work across multiple devices. When you provide a URL, the platform automatically captures screenshots at both standard desktop and mobile screen sizes. This allows designers, developers, and clients to review and provide feedback on how the site appears and functions on different screen breakpoints simultaneously. This feature ensures that responsive design issues are caught and communicated visually early in the review process, preventing problems from being discovered only after launch.

Secure Share Links & Guest Access

Collaboration is made effortless with Proofapp's sharing system. Project owners can generate a secure, shareable link to send to clients or external stakeholders. Crucially, reviewers do not need to create a Proofapp account to view the project and leave comments, which drastically reduces friction for client feedback. These links can also be set to expire after a certain period, and the platform offers role-based permissions for enterprise users, providing control over who can view or comment on sensitive projects.

Real-time Collaboration & Notifications

Proofapp turns static feedback into a dynamic conversation. When a team member or client leaves a new comment or replies to an existing thread, all other participants with access to the project are notified in real-time. This live-updating dashboard ensures everyone is on the same page, can respond quickly, and see the progress of feedback resolution as it happens. This feature integrates with tools like Slack to push notifications, keeping the team connected and moving forward without constant manual checking.

Streamlined Content Publishing

Businesses that produce frequent content for multiple social media channels can use Postproxy to automate their publishing workflow. This ensures consistent messaging across platforms while minimizing the risk of errors.

Integrated Marketing Campaigns

Marketing teams can leverage Postproxy to launch integrated campaigns that require simultaneous posting across various social networks. This enables cohesive branding and messaging, driving better engagement and outreach.

Automation with LLMs

Teams utilizing large language models (LLMs) for content generation can integrate Postproxy into their automated workflows. This allows for the seamless publishing of AI-generated content, ensuring it reaches the desired audience without additional manual intervention.

Efficient Social Media Management

Agencies managing multiple clients can benefit from Postproxy by simplifying the management of their clients' social accounts. By centralizing the publishing process, agencies can save time and focus more on strategy and creativity.

Freelancer Client Approvals

Freelancers, such as web designers or developers, can use Proofapp to collect clear, organized feedback from their clients. By sharing a simple link, clients can point directly to what they want changed on the design mockup or live site. This professional approach saves hours typically spent deciphering email descriptions, reduces revision rounds, and helps freelancers deliver exactly what the client envisions, leading to higher satisfaction and faster project completion.

In-house Design & Development Team Workflow

Internal teams can streamline their handoff and review processes. A designer can upload a prototype, and developers can pin technical questions or visual bugs directly onto the design. Project managers can track progress as comments are resolved. This centralized, visual system replaces disjointed communication across chat apps, email, and project management tools, creating a single source of truth for the project's feedback and required changes.

Marketing Campaign & Landing Page Reviews

Marketing teams often need to gather input from multiple stakeholders on campaign assets or new landing pages. Proofapp allows the entire team-sales, content, and leadership-to review the live page visually. Comments about copy, imagery, or call-to-action placement are pinned in context, ensuring feedback is specific and actionable. This collaborative review prevents last-minute changes and miscommunication before a high-stakes campaign goes live.

Agency Managing Multiple Client Projects

Digital agencies managing several client projects simultaneously need organized systems. Proofapp allows them to create separate projects for each client. They can then use secure share links to gather feedback, keeping all client communication visually organized within its dedicated project space. This prevents feedback from different clients from getting mixed up, improves accountability, and presents a professional, modern image to their clients.

Reviewers do not need to sign up for a Proofapp account to participate. The project owner simply generates a secure, shareable link from within their Proofapp dashboard and sends it to the client or stakeholder. When the recipient opens the link, they will see the captured website screenshots and can immediately click anywhere to leave a comment, attach files, and join discussion threads, all as a guest user.

Can I give different access levels to different reviewers?

Yes, Proofapp offers role-based permissions, especially relevant for team and enterprise use. Project owners can control access by assigning roles such as "Admin," "Commenter," or "Viewer." This ensures that sensitive projects remain secure, and you can control who is allowed to edit project settings, leave comments, or only view the feedback.
