What's New - June 2025 (ssr)

Written by Evelina Wahlström

Missing Image!

Ever seen content teams spend hours wrestling across disconnected tools, only to end up with a fragmented digital experience? This month, we're solving that problem with our Spring Release 2025: The Content Operating System.

It's our biggest release ever and is a result of thinking long and hard on how to enable developers to tailor how content works across your entire organization—backed by our recent $85M Series C funding round, which allows us to invest in improving Sanity as a platform and as a company further. (That's what the money is for).

In this update, you'll get a quick recap of of the new stuff in the Spring Release, some additional platform improvements we've shipped, and an exciting announcement: our first developer not-really-a-conference-maybe-more-like-a-festival in New York City, September 30th (with more details to follow soon).

I sat down with the engineers behind some cool features you'll want to try:

Spring Release 2025: Your complete guide 🚀

On May 8th, we launched the Content Operating System with a bunch of new features and products.

Feeling a little overwhelmed? I get it.

It's a foundational shift of the platform and eight new products / features / tools is a lot to take in. Let me walk you through what each one does, then I'll show you the best way to get hands-on with what matters most to your projects.

Quick recap

📊 Dashboard & Insights – Your content command center that unifies all Sanity resources across projects with automatic activity tracking.

🔧 App SDK – Build custom content experiences with live updating document lists, automatic draft creation, and multiplayer editing

⚡ Functions – Serverless automation for everything that happens next—validate content, trigger external services, or transform content with AI Agent Actions

🎨 Canvas – From rough draft to structured content with AI—no more copy-pasting between tools

🤖 Agent Actions – Schema-aware AI that validates outputs against your content's structure, eliminating tedious reformatting work

📚 Media Library – Centralized asset management across all your projects

🤖 Content Operations Agent – AI agent that audits, organizes, and suggests content updates (private beta, more on this later)

📖 Revamped Docs – CMD+F anything, ask AI, copy as markdown, new reference docs, and more

Have more questions?

Head over to Discord where we have dedicated support channels for each new feature. Our engineers have been quick to answer questions and fix bugs when reported.

Working for an agency?

Tom Smith, Senior Solution Engineer, has written a comprehensive guide for agencies navigating Spring 2025 organization changes. It covers when to create separate organizations for clients, project transfer processes, and billing considerations—essential reading as we shift to organization-centric features.

Content Operations Agent (Private beta)

What if you could get instant reviewing of your content - someone who systematically audits your documents, spots gaps, and suggests improvements without missing anything?

The Content Operations Agent works like a diligent co-worker. Think of it as having a content expert collaborating with you, catching things you might miss while you focus on the creative decisions (and still have full control over what and when to publish!).

Want a first look at what this looks like? I sat down with Rosti to see it in action.

PortableText [components.type] is missing "muxVideo2"

The Agent relies on our recently released Sanity MCP Server and Agent Actions—it's all connected to give you this seamless content review experience.

What else we've been building

Beyond our major release, we've continued improving core platform features based on the latest changelog updates:

Save frequently used GROQ queries in Vision

Finding yourself running the same queries in Vision all the time? Maybe you have a "GROQ query" note somewhere that you have to copy-paste from? (I do!)

Well, no more!

Save your queries: You can now save frequently-used GROQ queries in Vision, making it much easier to iterate on complex queries during development.

Structure Builder divider improvements

Structure Builder's divider() method let you add visual dividers in a document list to "group" list items to make it easier to parse. Now, you can add a title and translations to the divider in the structure builder, making it even easier to organize and localize your document list experience:

S.divider().title('Products')

Custom GROQ functions

The query endpoint now support custom defined GROQ Functions in all versions above v1. This allows you to create modular, reusable parts of queries for more maintainable code.

You can test it out by defining a reusable function like this:

// Define a reusable function
fn ex::name($person) = $person-> { "name": firstName + " " + lastName };
*[_type == "post" && defined(slug.current)] {
  title,
  slug,
  publishedAt,
  "author": ex::name(author),
  "excerpt": pt::text(body[0...3])
} | order(publishedAt desc) [0...10]

Read the documentation for more information, and stay tuned for more examples (and videos!).

Overlay plugins

Instead of diving through documents to find what you need to edit, this set of Overlay plugins gives you granular control over individual elements by adding custom controls and information directly to your presentation overlay.

I sat down with James and Rupert to see this in action—from simple word counters to a full Pokemon-style level editor that lets you edit game tiles directly on the visual interface. Rupert's game demo perfectly shows when editing in Presentation beats the Structure tool: instead of scrolling through hundreds of array items, you can see exactly what you're editing and where.

Schema deployment

The CLI now supports schema deployment, enabling features like Dashboard, Agent Actions, and improved Canvas experience by allowing Sanity's apps to understand your schema beyond just Studio. This foundational change unlocks better integration across the entire Content Operating System.

React compiler integration

Sanity Studio now uses the React Compiler RC, delivering 20-30% performance improvements across our codebase. We've been working closely with the React team as part of their working group, testing the compiler on our most performance-critical libraries like @sanity/ui, @portabletext/editor, and react-rx.

The results speak for themselves: our performance testing suite shows significantly higher frames per second (FPS) during editing interactions—the kind of latency that really impacts creative professionals staying in their flow.

PortableText [components.type] is missing "protip"

Post Spring Release updates

Our Engineers didn't stop iterating on our new features and products after our big release. Below are some key improvements to Agent Actions, Functions and Canvas that you may have missed.

New Agent Actions:

Enhanced image generation:

You can now generate and transform images directly by targeting image asset paths, making AI-powered visual content creation much more flexible.

TypeScript support for Functions

Build type-safe serverless workflows with full TypeScript integration and official type packages. When you run sanity blueprints add function and select TypeScript, you'll get prompted to include the type package and handler automatically.

Enhanced Canvas Studio integration

Publish Canvas-linked documents directly from Studio and add them to Content Releases without switching contexts. We've also simplified studio linking—compatible Studio versions now automatically appear in Canvas as valid targets for content mapping.
