Sanity vs Strapi: Choosing a Headless CMS

Sanity is a hosted content platform built around GROQ. It's a query language that resolves deep nested references in one call. Strapi is an open-source CMS you self-host, storing content in a SQL database you control. Pick Sanity for real-time editing and deep reference joins. Pick Strapi for full infrastructure control and no per-seat pricing.

This guide compares the two directly. Our Sanity alternatives roundup already covers Sanity against Payload, TinaCMS, and Draftbase. This page answers a narrower question: Sanity or Strapi, specifically.

Architecture: Hosted Content Lake vs Self-Hosted Database

Sanity stores every document in its Content Lake. That's a hosted database, reached only through the Sanity API and GROQ. There's no self-host option. You query it, you don't run it.

Strapi runs on infrastructure you control. Content lives in a SQL database of your choice, Postgres or MySQL. A Node.js process serves the admin panel and API alongside it. That's real ownership, and real maintenance. Someone has to patch the server, back up the database, and handle uptime.

GROQ vs Strapi's REST and GraphQL

GROQ is Sanity's real differentiator. One query can project, filter, and resolve references at any depth. A blog post with an author reference and three tags comes back fully joined in a single round trip.

Strapi has no GROQ equivalent. It ships REST and GraphQL, both solid for most content-fetching needs. A deeply nested reference structure, three or four levels of linked content, takes more calls in Strapi. Or a heavier GraphQL query, for the same shape Sanity handles in one.

Does every project need GROQ's depth?

No. A blog with a post, an author, and a couple of tags doesn't benefit much from deep joins. That shape is common, and REST or GraphQL handles it without friction. GROQ earns its learning curve on a genuinely deep content model, not a flat one.

Real-Time Editing vs Self-Hosted Control

Sanity's real-time collaboration works at the field level. Two editors can type in different fields of the same document at once, with no lock and no save conflict. That's a real engineering investment, and no self-hosted CMS replicates it out of the box.

Strapi has no equivalent. Editors work one at a time on a document, the same as most CMS admin panels. What Strapi trades for that is infrastructure ownership. No vendor-hosted database. No data leaving your own servers. No per-seat fee tied to editor count.

Pricing: Per-Seat vs Infrastructure Cost

Sanity's free tier covers three users and 10,000 API requests a day. That's generous for a small project. Past that, Growth pricing runs per seat, and a 10-to-15-person editorial team feels that bill directly.

Strapi's license is free either way. The cost moves to infrastructure instead. Realistically $50 to $200 a month in hosting, plus the engineering time to keep it patched and running. Strapi Cloud, the managed option, starts with a free plan and scales to $499 a month on the Team tier.

Sanity vs Strapi: A Practical Comparison

	Sanity	Strapi
Hosting	Hosted only, Content Lake	Self-hosted, or Strapi Cloud
Query language	GROQ, deep joins in one call	REST / GraphQL
Real-time editing	Field-level, built-in	None
License cost	Free tier, then per-seat	Free (MIT), self-hosted
Best fit	Deep content models, many concurrent editors	Teams with DevOps capacity wanting full control

Contentful vs Sanity: A Quick Aside

Contentful and Sanity get compared often enough to mention here. This guide's main pairing is Sanity and Strapi, but the aside is worth a paragraph. Contentful treats its content store as a black box behind REST and GraphQL. Sanity opens that box with GROQ and lets you query it directly. If GROQ's join power is the deciding factor, Sanity beats Contentful the same way it beats Strapi's REST-only model.

When to Pick Each

Pick Sanity when your content model has real depth, several levels of linked references. Pick it too when your editorial team is small enough that per-seat pricing stays reasonable. The real-time editing pays for itself once multiple editors work the same documents daily.

Pick Strapi when a data-residency rule keeps content on infrastructure you control. Or when your team already runs servers and doesn't want a vendor-hosted database in the loop. The plugin ecosystem also runs deeper than Sanity's, if a pre-built integration saves real time.

What This Choice Actually Costs Later

Migrating away from either platform later carries a real cost, just a different kind. Sanity's Portable Text format has no shared open standard. Leaving means writing a custom converter for every consumer of that content. Strapi's rich text is usually plain HTML or a simpler JSON shape. That migrates more predictably. But self-hosting means the exit cost shows up earlier, in the ongoing hours spent running the server.

Neither cost disappears by picking the other option. It just moves to a different point in the project's life. Weigh which one your team is better positioned to pay: a migration years from now, or infrastructure hours starting today.

What About Team Size?

A solo developer or a two-person team should weigh Strapi's ops burden heavily. Running a database, patching a Node process, and monitoring uptime is a real chore, even with a free license. That's hours spent on infrastructure instead of content or product work, every month the project runs.

A larger team with dedicated platform engineers absorbs that cost more easily. Self-hosting buys something real in return. No per-seat pricing. No API rate limit set by someone else. The option to run the CMS next to the rest of the stack. That's a fair trade once keeping servers healthy is already someone's job.

The editorial team's size matters separately from the engineering team's. Sanity's real-time editing pays off once several non-technical editors work in the same documents at the same time. A single writer working alone doesn't need that feature, and paying Sanity's per-seat price for it is a mismatch either way. Count both team sizes before picking, not just the one that writes the code.

What Content Modeling Feels Like Day to Day

Sanity's schema is defined in JavaScript or TypeScript, with a visual Studio for editors built on top of that same schema. A developer writes the field definitions once, and the Studio's editing UI reflects them automatically, no separate admin-building step.

Strapi takes a more visual route by default. Its content-type builder lets a non-developer add a field through the admin panel, with no code change required. That's a real advantage for a team where content modeling isn't strictly an engineering task, though it can also mean schema changes happen without a code review, which some teams prefer to avoid.

Neither approach is wrong. A team that wants schema changes tracked in version control, reviewed like any other code, leans toward Sanity's model. A team that wants an editor to add a field without waiting on a developer leans toward Strapi's.

Conclusion

Sanity and Strapi solve different problems well. GROQ and real-time editing against full infrastructure control and no per-seat pricing. Neither one is a universal upgrade over the other. The right pick depends on content depth, and who's running the servers.

Draftbase is worth a look too, if MDX-native storage sounds closer to what you need. No Portable Text rendering overhead, and no self-hosting burden. See the full Sanity alternatives comparison for how it stacks up against Payload and TinaCMS too. Start on Hobby for free, no card required.
