There's a meeting that happens on almost every enterprise headless build. The stack is agreed: Sanity for content, Next.js on the front, Mux for video. Then someone from marketing or procurement asks the question that adds a quarter to the timeline: "where does the DAM go?"
I'm going to leave names out of this, but trust me, it always happens. The most recent time was a client mid-migration off a legacy CMS onto Sanity and Next.js, with a dedicated DAM on the table, and the answer we ended up settling on, is the same thing I'm going to recommend in the post. You probably don't need a DAM, and you're overkilling it.
What people think they're buying
Having sat through a lot of these conversations, the push for a DAM comes from three places, one of these is the right answer, the other two you're making a mistake.
The checkbox habit. Someone had Bynder at their last company, or a DAM line item is sitting in an RFP template from 2019. You should absolutely not be doing this, you're going to have a sub-optimal experience.
Brand asset governance. This one is real. Marketing wants a single source of approved logos, imagery, and campaign assets, with usage rights and expiry dates attached, so nobody ships a photo whose licence lapsed in March. If the website team can't offer this, the DAM conversation starts without them.
Volume fears. "We have thousands of assets, surely we need dedicated tooling for search and tagging." No, no, no, no. Unless you're clickbaiting every article with a high-res image, your traffic is very unlikely to cap out the Sanity media library. And even if you somehow get close, the overage costs pennies on the dollar against a DAM licence.
A dedicated DAM answers all three, which is why the pitch works. The problem is what it costs and what it duplicates.
The DAM is already in your stack
If you didn't know, Sanity has its own enterprise media library, and if you're looking for a DAM chances are you're already an enterprise client. Hell, why do you think we're targeting this keyword.
The Media Library is Sanity's actual DAM: an org-level asset repository that sits above your projects rather than inside one dataset.
Run down the governance list from that procurement meeting:
- One library, every project. Upload the logo once, reference it from all eight sites. No duplicate uploads, no "which version is current" archaeology.
- Rights management on the asset. Licences, expiry dates, approved territories, attached to the file itself rather than living in a spreadsheet nobody opens.
- Custom metadata through Aspects. Code-first schemas for whatever your team needs on an asset: campaign, photographer, product line. It's the same schema thinking as the rest of Sanity, so your developers already know how to extend it.
- AI search over content, not filenames. The library indexes subjects, scenes, and colours, so "person climbing at sunset" finds the image regardless of it being called
IMG_4711_final_v3.jpg. - Versioning with rollback, role-based access, and authenticated delivery for the assets that shouldn't be public.
That's the feature list a DAM vendor reads you on the demo call, native to the platform your editors already work in. No sync pipeline, no second login, no integration project to get assets from the library into the page. I can't stress how much of a crap experience working with Sanity with a plugin media library is, if it's not native, it feels jank.
The distinction Sanity draws, and the reason this beats a bolted-on DAM for a website team, is that assets are structured, queryable content. An image in the Media Library is a document your front end queries like any other, not a file behind someone else's API that you mirror into your CMS and hope stays in sync.
Video is where the DAM argument really falls over
Here's the part the DAM pitch glosses over: a DAM doesn't solve video. It stores video, which was never the hard part.
The hard parts of first-party video are delivery and everything around it. A 200MB MP4 in a beautifully governed asset library is still a 200MB MP4 when it hits a phone on 4G. What you actually need is adaptive streaming: the upload transcoded into a ladder of renditions, each visitor served the version their device and connection can handle. That's what Mux does, and it's why video loading well feeds directly into your Core Web Vitals, which remain one of the levers on your rankings.
Just to give you context on this, here's all the different formats you need to provide one video in a nice, mobile/tablet/desktop optimisable format. Mux gives you this off the bat, without this crazy boilerplate.
Fourteen files, eleven codec strings you'd better get exactly right, and an ffmpeg pipeline to regenerate the lot every time someone re-exports the master. And here's the kicker: it's still not adaptive. The media attributes pick a file by viewport width, not bandwidth, so the phone on hotel wifi gets the same 720p it would on fibre and buffers anyway. Actual adaptive streaming means generating HLS or DASH manifests on top, shipping hls.js for every browser that isn't Safari, and writing the retry and quality-switching logic yourself.
Or:
So buy the DAM or don't, you still need Mux. A DAM can't stream, which leaves it with exactly one job: being a governed image library. Sanity's Media Library already is one. If something's getting cut from the stack, it isn't the video platform.
The Sanity side of this is first party too. The mux-input plugin is maintained by Mux and Sanity together: editors upload from the Studio, and playback IDs, thumbnails, and captions land in the document without anyone touching the Mux dashboard. We've run this combination in production for years and wrote up our exact player component separately.
Aren't we going to hit overages?
The "thousands of assets need a DAM" instinct deserves a straight answer, so here's ours: the biggest libraries we've run through Sanity + Mux without a DAM sit in the 5,000 to 20,000+ asset range, with multiple editors in them daily. Search and organisation held up, because AI discovery over image content is doing the job manual tagging used to justify.
Video at volume is where it gets interesting. Adding five videos to a website is no sweat; nobody needs tooling for five videos. At 500, you need a system, because nobody hand-writes captions, titles, tags, and descriptions for a back catalogue that size, and crawlers can't watch video. Whatever a video contains, the only part search engines and AI assistants can index is the text attached to it.
This is Mux Robots territory: hosted AI workflows that run against your library, generating captions (22 languages for on-demand video), translations, dubbed audio, tags, summaries, and thumbnails. Mux shipped six new workflows in July 2026, including premium captions on higher-accuracy speech models. Metadata-at-scale is half of what teams think the DAM is for, and Robots turn it into a batch job.
The numbers
DAM pricing is famously "book a demo", so here's what we can tell you from the quotes and renewals clients have actually shown us, next to what the Sanity + Mux equivalent costs. Mux prices checked against mux.com/pricing on 6 July 2026.
| Item | Cost |
|---|---|
| Dedicated DAM licence (quotes we've seen) | Mid five figures per year ($30k–70k) |
| DAM → website integration build | Scoped separately, and someone owns it forever |
| Sanity Media Library | Part of the Sanity platform you're already on |
| Mux free tier | 100,000 delivery minutes/month, up to 10 stored videos |
| Mux storage (720p baseline) | $0.0024 per minute per month |
| Mux delivery (720p baseline) | $0.0008 per minute after the free 100k |
| Mux encoding (Plus tier) | From $0.025 per input minute |
| Mux Robots workflows | $0.0003–0.005 per minute, plus per-job fees |
Run the maths for a realistic marketing site. A 500-video library averaging two minutes a video is 1,000 stored minutes: roughly $3 a month in storage at 1080p. Delivery costs nothing until you stream 100,000 minutes in a month, which a marketing site doesn't approach. Encoding the whole library is a one-off in the $25 to $40 range. Our own bill for robotostudio.com is effectively nothing. Sorry Mux team.
Against a renewal in the mid five figures, every year, for a system that still doesn't stream video, I honestly find it difficult to recommend them ever.
There's a second saving that never shows up on a quote: vendor count. Every tool in an enterprise stack is an InfoSec review, and those reviews are measured in calendar time. A headless build already asks the security team to onboard a CMS and a video platform. Cutting the DAM is one fewer procurement cycle, one fewer data processing agreement, one fewer renewal negotiation in two years.
When a DAM actually earns its place
We'd be doing the demo-call thing ourselves if we said never, so here's where I think you might want one: it's rare, but the use-case is specific.
A DAM makes you pay for every workflow it bakes in, whether your team uses it or not. Our default is the opposite: build the one plugin your editors actually need. The Studio is designed to be extended, a focused plugin is days of work, and you own the result. Against a mid-five-figure annual renewal, that trade wins almost every time.
Where it stops winning is when multiple projects rely on the same asset workflows but never really communicate: separate sites, apps, print teams, and regional operations all pulling from one governed library, most of them nowhere near Sanity. At that point you'd be rebuilding a cross-platform distribution product plugin by plugin, and the build cost genuinely can climb past the licence. That's the case where the DAM is the cheaper system. If every consumer of your assets is a Sanity project, you're not in it.
Two more things to go in with your eyes open on, both Mux-side. Transcoding is lossy: the file you upload is the best that video will ever look, and it shows most on high-detail 4K masters with on-screen text. The worst example on our own site is the Slingshot Bio case study, and you can see the crunchiness if you look for it.
And any player on a page costs performance. Our answer is the lazy-loaded facade in the component post: nothing heavy loads until the reader asks for the video. We have a more modern version of this, but we haven't written it up yet.
The verdict
If your assets exist to be published through Sanity, the DAM conversation is over before it starts: the Media Library is the governed, searchable, rights-aware repository the procurement checklist is asking for, and Mux covers everything a DAM was never going to do with video. That's the stack the clients in this post landed on, and it's the one we'd pick again.
Reserve the dedicated DAM for the one scenario that justifies it: many disconnected projects sharing one asset operation, where building the connective tissue yourself costs more than the licence. Everyone else is paying mid five figures a year for a second place to put the logo.
