Can an agent replace Sanity?
A developer-first headless CMS with a customisable editing studio and a queryable content lake.
No. Sanity is where the content lives and what your front end reads from. An agent drafts, edits and publishes through the API happily. The free tier covers most small teams, so there is barely a bill to attack anyway.

- What it actually costs
- free tier covers most small teams; Growth ~€15/user/mo
- Verdict
- The agent does the work inside it. The tool stays because that is where the data lives.
What the agent takes over
Every job this product exists to perform, with our verdict on each. Follow one through for the step-by-step breakdown.
- Content writingHalf. An agent gets you a structurally sound draft in minutes and will never get you a piece worth sharing on its own. The gap is not writing ability — it is that it has nothing of its own to say.HALF
- DocumentationYes, and it fixes the real problem, which was never writing documentation but keeping it true. An agent regenerates docs as the code changes, which no human team has ever sustainably managed.YES
- SEOMostly. Technical audits, internal linking, schema, briefs and refreshes are agent work now, and tedious enough that they usually go undone. What an agent cannot manufacture is the authority, originality and relationships that decide who actually ranks.MOSTLY
Why it survives
It is the record. An agent working inside it makes it more useful, not less.
What you would still need it for
- The content lake your sites query
- The studio, for the humans who still review what ships
What replaces it
- An agent writing and patching documents through the API, with a human eye on the studio
The brief
What you would tell an agent to take over from Sanity, assembled from the jobs above.
I want to cut the work inside Sanity. It currently does: A developer-first headless CMS with a customisable editing studio and a queryable content lake. Take over this work: - Content writing — HALF. Half. An agent gets you a structurally sound draft in minutes and will never get you a piece worth sharing on its own. The gap is not writing ability — it is that it has nothing of its own to say. - Documentation — YES. Yes, and it fixes the real problem, which was never writing documentation but keeping it true. An agent regenerates docs as the code changes, which no human team has ever sustainably managed. - SEO — MOSTLY. Mostly. Technical audits, internal linking, schema, briefs and refreshes are agent work now, and tedious enough that they usually go undone. What an agent cannot manufacture is the authority, originality and relationships that decide who actually ranks. Do not take over: - The content lake your sites query - The studio, for the humans who still review what ships These stay with me across all of it: - The argument - Anything drawn from your own experience - Final edit and the decision to publish - Architectural rationale - Deciding what deserves documenting - The overall narrative - Positioning - Genuine expertise in the content - Relationships that produce links - Deciding what not to publish Before we start, tell me: which of these you cannot do with the access I can actually give you, and what would break if this ran unattended for a month. — brief built at cananagentdo.com/sanity

Keep the tool, cut the hours
Sanity is not the line item worth attacking. The money is in the people-hours spent working inside it, and that is what an agent takes over — with Sanity still holding the data.
