Proofapp
Visual Commenting
Forget describing where something is with "top left, under the nav, next to the blue thing." Proofapp's visual commenting lets you and your reviewers click directly on the live screenshot to drop a pin and leave feedback. It's context on steroids. Every comment is visually anchored to the exact pixel, eliminating all guesswork and turning vague notes into crystal-clear, actionable tasks. Threaded replies keep the conversation organized right where it matters.
Multi-Breakpoint Testing
Your site needs to look fire on every device. Proofapp gets this. The moment you paste a URL, it automatically captures crisp screenshots at both desktop and mobile breakpoints. Reviewers can seamlessly switch between views to leave feedback specific to each layout. This means you catch responsive design issues early, ensuring your client doesn't text you a blurry mobile screenshot with a sad face emoji after launch.
Secure, Account-Free Sharing
Chasing clients to create yet another account is a vibe-killer. With Proofapp, you just generate a secure, shareable link and send it. Your clients click, review, and comment—no login, no password, no friction. You can even set links to expire for extra security. It’s professional, polished, and removes every barrier to getting the feedback you need, fast.
Real-Time Collaboration & Notifications
Watch feedback roll in live, like a group chat for your project. When a teammate or client drops a comment, you see it instantly—no refreshing the page needed. Get pinged with real-time notifications and stay in the loop with Slack integration. Reply, resolve threads, and track progress together in a single source of truth. It turns slow, staggered email loops into a dynamic, synchronous conversation.

Proofapp
Freelancers Managing Client Approvals
As a freelancer, your time is money, and looking pro is everything. Proofapp lets you ditch the messy email chains and shared Google Docs full of confusing notes. Send a clean Proofapp link to your client for feedback. They click to comment visually, which saves hours of back-and-forth decoding. You get precise, actionable feedback that makes revisions a breeze, helping you deliver faster and look like a total rockstar.
Design Teams Iterating on UI/UX
Internal design reviews can get messy with opinions flying everywhere. Proofapp gives your design team a centralized, visual hub for critique. Pin feedback directly on the latest mockup or live prototype. Discuss in threaded comments, attach inspiration files, and resolve issues as you go. It streamlines the iteration process, ensuring everyone is literally on the same page and reducing revision rounds dramatically.
Development Teams Handling QA & Bug Reports
Trying to describe a visual bug in a ticket is the worst. "The button is misaligned on mobile" is not helpful. With Proofapp, QA testers or product managers can capture the live site and pin comments directly on the glitch. They can attach console logs or videos. Developers get a perfect visual bug report with exact location and context, slashing the time spent reproducing issues and fixing them.
Marketing Agencies Reviewing Campaign Pages
When launching a new campaign, feedback comes from all directions: copy, design, CRO, the client. Proofapp consolidates this chaos. Share the landing page link with the entire team and client. Everyone can leave targeted feedback on specific elements—hero image, CTA button, form layout—in one organized place. It ensures the final page is polished and on-brand before it ever hits the public.

Frequently Asked Questions
Postproxy FAQ
How does Postproxy handle authentication?
Postproxy simplifies authentication by managing OAuth flows, token storage, and automatic refreshes for you. This means you can focus on creating great content instead of wrestling with access permissions.
Can I publish to multiple platforms at once?
Absolutely! With Postproxy, you can publish your content to multiple social networks with a single API call, saving time and reducing the complexity of your publishing pipeline.
What happens if a post fails to publish?
No worries! Postproxy features robust error management, which includes automatic retries and clear reporting of publish states. You’ll always know what went wrong and why, allowing you to take action when necessary.
Is there a free plan available?
Yes! Postproxy offers a free plan that allows you to explore its features and capabilities without any financial commitment. Scale as your needs grow, making it an excellent choice for startups and developers.
Proofapp FAQ
How do reviewers leave comments without an account?
It's stupid simple. You, as the project owner, create a review link in Proofapp. You send that link to anyone you want feedback from—clients, teammates, your grandma. They click the link, your website screenshots load, and they can immediately start clicking and commenting. No sign-up, no password, no barrier. They're in and giving feedback in under 10 seconds.
What happens after I resolve a comment?
When you mark a comment as "Resolved," it gets neatly tucked away in a resolved section, cleaning up your active feedback view. But it's not gone forever! You and your team can always go back to view the entire history of the conversation. This gives you a perfect audit trail of all decisions and changes, which is golden for onboarding new team members or justifying choices to a client later.
Can I use Proofapp on a local development site?
Yes, but with a quick workaround. Since Proofapp needs a public URL to capture screenshots, you'll need to use a local tunneling tool (like ngrok or LocalTunnel) that exposes your localhost to the internet with a temporary public URL. Paste that generated URL into Proofapp, and you're good to go! It's perfect for getting early feedback before you even push to staging.
Is there a limit on projects or comments?
The free tier is seriously generous, designed to let you truly test the workflow. You get a solid number of active projects and unlimited reviewers and comments. If you're a power user managing tons of concurrent projects for multiple clients, you'd look at the paid Solo plan. It lifts those limits, giving you unlimited active projects and more advanced features to scale your workflow.

Postproxy is the ultimate social media publishing API, a powerhouse in the design and automation tool category that unifies platforms like Instagram and LinkedIn into one slick endpoint. It’s the secret weapon for developers and creators who want to automate their feed without the chaos. But let's keep it real—no single tool is a perfect fit for everyone. You might be hunting for alternatives because your budget’s tight, you need a niche feature, or your tech stack demands a different vibe. It’s all about finding the right gear for your specific grind. When scouting for other options, you gotta look under the hood. Prioritize a rock-solid API, smart error handling that doesn’t ghost you, and clear pricing without hidden traps.

Proofapp Alternatives
Proofapp is your go-to design review sidekick, slashing through the chaos of client feedback. It lives in the design tools arena, letting teams and freelancers drop visual comments directly on live website screenshots. It’s all about killing vague email chains and making feedback pop, literally. But let’s be real, no single tool is everyone’s perfect match. You might be hunting for a different vibe—maybe the price tag doesn’t vibe with your budget, you need deeper integrations with your project management stack, or you’re craving more advanced features like video annotations or developer handoff. The search for an alternative is totally valid. When you’re scoping out the competition, keep your non-negotiables front and center. Think about your squad's workflow, the must-have features that’ll save you hours, and how much you’re willing to invest. The goal is to find a platform that feels like an extension of your team, not another annoying app to manage.
