Cage vs Approval Studio: An Honest 2026 Review and Comparison

Last updated: July 2026

Some time ago, an Oklahoma company of enthusiasts produced an exciting collaboration tool called Cage, and we will pay it a visit again. It’s a 2026 update of our previous review, where we’re about to see if any interesting updates have been developed. This year has been pretty fruitful for comparisons.

We’ve already had more expensive tools (like Ziflow and Pageproof) and more accessible ones (like QuickReviewer, ReviewStudio, and Govisually) on our night show. As usual, I’ll try to be as unbiased as possible and give you an honest review across three main categories: review & proofing, version management, and integrations. And then we’ll show you a strong Cage alternative and work out which tool you need based on what each does best! Let’s check!

What is Cage?

So, if Capterra is right, Cage was established in 2011. That kinda surprised me, to be honest, because I thought this app was among the recently launched ones. The reason for my prejudice was that it does not have all the basic features I’m used to seeing in other proofing apps… but let’s not jump to any conclusions beforehand and start from the very beginning.

They claim to be a versatile tool “from solo to enterprise”, offering users very similar features across all the plans, just keeping the seat count, storage, and support tier as the real levers between them. 

The list of Cage features is honestly impressive. They focus heavily on delivering a sound and affordable tool for the teams that need an easy way to review designs and get approvals. Everything we love: simple for the team, simple for the client! However, let’s look at all the features more in-depth. 

CageApp features

Let me talk about the method a little bit. What I do in each of our comparison articles is research everything there is to the tool, CageApp in our case, and then summarize it according to three main online proofing categories: review & proofing, version management, and integrations. So you’ll see the tool’s features in the category and my thoughts on it, mixed with the real reviews found on various platforms. So, I’m ready whenever you are!

Review & Proofing

So, the actual Cage review tool is pretty easy and straightforward, especially for those who have never used a review tool before (and that’s going to be, what, nine out of ten of your clients?) 

• Sketch, circles, and highlight annotations
• DeepZoom for inspecting fine detail
• @ mentions and public vs. private comments
• Timestamped approvals with a file status view (ready / approved / has comments / new version)
• Roles (Administrator / Team Member / Reviewer / Group) and Flexible Sharing by password, public link, or email
• “Your tasks” section to track what has to be done
• File presentations

Honest opinion: Listen, when your internal process is easy, you don’t really need much. However, CageApp closes that “not needing much” and opens a door to a bit more convenient approval process. Another thing that people point out is that it’s just good to look at. And the dashboard that allows you to track tasks, projects, and your team in a simple view works great for every overworked creative and manager out there. So, from me it’s definitely a “it does the job and looks nice doing it” out of 10. 

Version Management

Happy manager, happy life! And the manager is happy when the work gets done on time and with all the documentation that’s needed. Online proofing tools usually have different version management features to help with the second, and CageApp isn’t an exception. 

• Version history with date/time stamps
• Comment history is preserved per version, not lost on upload
• Resolve outstanding feedback to mark what’s been addressed
• Only saves the versions you choose to share, not every autosave
• Asset Management and Storage 

Honest opinion: I feel like the word basic is going to be a cornerstone of today’s review. And it isn’t bad. Many users don’t need extra features; they just want to see when their design was approved, by whom, and what changed. Even more, I saw multiple reviews talking about how Cage helped them record the work and keep track of how it’s going. However, what I have not seen are the compare modes, which, for me, are the most crucial part of the entire second round of reviews. So, for me it’s not more than “I can use my eyes anyway” out of 10. 

Integrations

The cardinal rule is that you don’t change the workflow for the review tool, but it adapts to yours. And integrations play a big part in this rule. Here’s what Cage is offering:

• Slack
• Dropbox
• Adobe XD
• Adobe Photoshop
• Chrome Extension

Honest opinion: a great starting point for any freelancer or creative team. You’ve got something for communication, something for storage, and something for the designs themselves. However, the more exciting stuff is on their coming soon page with Figma, Adobe Premiere Pro and After Effects plugins. So, “great, can’t wait” out of 10 from me. 

Cage pricing

Now that we know enough about CageApp features, let’s see how much you will have to pay for them. For convenience, I offer you a direct comparison with Approval Studio and some features you’re going to get with the tools. Before making any decisions, I recommend checking the official pricing pages for Approval Studio and CageApp. 

Pro XL ($300/mo) includes up to 15 users and 30GB storage, same features as Pro. Both products also offer Enterprise tiers on request.

Cage vs Approval Studio: feature comparison

Here’s a complete side-by-side comparison of every major feature as of 2026:

Approval Studio features

Now that we’ve discovered how Approval Studio works in big strokes, let’s get down to more detail. I’m going to show how Approval Studio’s features compare with CageApp across the same three categories, but to be more neutral, I won’t score them and leave it all to you. 

Review & Proofing

Feature-wise, Approval Studio’s review tool is the more capable of the two. CageApp supports more file formats on paper, but once you’re actually inside a proof, Approval Studio gives you more to work with.

• 5 annotation shapes with pinned comments directly on the artwork
• Live chat in the review tool, no page refresh needed
• Selective approval: allow clients to choose one design from among many
• Full accountability log (who approved, when, which version)
• Customizable review invitations to input your logo, text, and any information you need
• Notifications for new feedback, approvals, and upcoming deadlines
• Packaging-specific: color separation, overprint simulation, barcode reader, on-screen ruler
• Trigger-based workflows for automated routing

Version Management

The two tools are pretty alike here. However, Approval Studio goes a little further, offering you fewer opportunities to make a mistake. 

• Automated file versioning and cycle management
• Four comparison modes: side-by-side, side-by-side with difference, fader and toggle
• Proof report for every version and the project as a whole
• Digital Asset Library (DAL): one central place to store all your assets

Integrations

Approval Studio’s integration list is deeper than CageApp’s, and most of the integrations start in the PRO version. 

• Shopify integration, ideal for e-commerce creative approval workflows
• Adobe Creative Cloud
• Slack
• Zapier
• REST and GraphQL API
• MCP server for n8n, Make, or AI-agent integration
• Native iOS and Android app

Which is best for me?

Listen, as much as I would love you to get on Approval Studio’s side (it’s really cool, I promise), I understand that it might not be the right tool for you at the moment. And that’s okay, cause each of our workflows is completely different and requires different things. That’s why, at last, I present you with use cases for each app. I hope this will help you identify yourself in one of these and move on with the best-fitting tool for you, specifically. 

Who should choose Cage?

Cage is a solid fit for the freelancer who wants something genuinely simple and nothing more. If your workflow is “upload a design, send the client a link, get a yes,” you don’t need a heavy tool, and CageApp doesn’t try to be one. The free-forever plan gives a solo designer one project, a clean review tool, and a place to collect feedback without paying a cent or sitting through a learning curve. Your client opens it, clicks around for thirty seconds, and figures it out on their own. That’s the whole appeal.

It also works nicely for micro teams, the two- or three-person operations where everyone wears five hats already. At that size, you get the useful bits, roles for who sees what, private team comments before the client weighs in, and a shared space to keep files and feedback together, without the tool feeling bigger than the team using it. Per-seat pricing barely registers when there are only a couple of seats to pay for, so a tiny team gets the collaboration features without the collaboration-tool price tag.

And that’s really the heart of it: CageApp is for teams watching their budget. Eight dollars a user is easy to say yes to, and the free plan means you can start at zero and only pay once you actually need to. If money is the deciding factor and your approval needs are straightforward, Cage earns its spot. Just know what you’re trading for that price: there’s no compare mode, and half the exciting integrations are still sitting on a “coming soon” page. For a lean budget and simple work, that trade is often worth it.

Who should choose Approval Studio?

The packaging or print team is who Approval Studio was practically built for. If your work ends up on a physical shelf, a two-millimeter shift or the wrong Pantone turns into a very expensive phone call and a very awkward meeting. The four compare modes, color separation, barcode reader, and many more tools are designed specifically to keep your final “shelf” design on the shelf.

The Shopify seller or e-commerce team gets something Cage can’t offer at all: a native Shopify integration. Approval Studio has a native Shopify integration in which you can use an online proofing tool inside your Shopify store. And with Selective Approval, it’s much easier to understand which version was approved cause everything is timestamped, named, and audited. 

The growing or AI-curious team is the third fit. And if you’ve got even one eye on where creative work is heading, Approval Studio is already there. The MCP server lets you point Claude, ChatGPT, n8n, or Make straight at your approval data, which is a genuinely forward step while most tools are still figuring out their first AI feature. It gives you a lot more room to grow. And the tool doesn’t punish you every time a new member joins. 

Final thoughts

So who wins? Short version: Cage is the cheaper, simpler pick for freelancers and small teams who want proofing with a bit of project management on the side. Approval Studio is the stronger choice for packaging, print, and growing teams that need compare modes, flat pricing, and deeper integrations.

I lean toward Approval Studio, but you don’t have to take my word for it. Cage is free to start, and Approval Studio gives you 14 days, so test both. And if you book a (completely free) demo, we’ll walk you through the whole system with PRO features included. 

Cheers!
