## Which one, for what

### Payload (C)

Good for: Teams that build on Next.js and want the content model in TypeScript, with drafts, versions and localisation in the free core.

Ahead on:
- Payments & pricing, 45 against 40

Also in its favour:
- Open source

Watch for: 49 security advisories in the 12 months to 8 October 2026, 8 critical, 38 of them published since 18 September 2026

### Sanity (BB)

Good for: Teams that model content as structured documents and want an agent to draft, patch and stage changes in releases for a person to publish.

Ahead on:
- Schema & documentation, 87 against 70
- Agent ergonomics, 74 against 64
- Security & auth, 67 against 57
- Maintenance & community, 89 against 78
- Transparency & trust, 87 against 62

Also in its favour:
- Agent-ready, a grade of BB or better
- A hosted endpoint, with nothing to install
- No incidents deducted, where Payload loses 10 points for them

Watch for: Schema validation rules run only in Sanity Studio. The HTTP mutation API accepts a document without checking them

## Verdicts

**Payload.** Payload generates REST, GraphQL and MCP interfaces from one typed config, with drafts, restorable versions and per-key MCP permissions in the free MIT core. The security record is the limit. The vendor published 49 advisories in 12 months, 8 of them critical, so an install older than 3.90.0 is exposed. No OpenAPI file is published.

**Sanity.** Sanity publishes 26 OpenAPI specs covering 225 operations, and its hosted MCP server saves edits to drafts or release versions, with publishing as a separate call. The Content Lake does not run schema validation on API writes, and custom roles that limit a token to one dataset or document type are sold only on Enterprise plans.

## Before you call either

### Payload

1. Check the installed version first. Anything below 3.90.0 carries published critical advisories, so ask the owner to upgrade before writing
2. Send REST keys as `Authorization: {collection-slug} API-Key {key}` and MCP keys as `Authorization: Bearer {key}`. The two key kinds are separate
3. To publish, set `_status: 'published'` in the data. The `draft` parameter only relaxes validation and chooses where an update is written
4. Upload files with multipart POST to the upload collection, with other fields as JSON in `_payload`. No MCP upload tool is documented
5. Roll back with `POST /api/{collection-slug}/versions/:id` after listing versions. Versions exist only where the collection config enables them

### Sanity

1. Pin a static dated version in every URL, such as `v2025-02-19`. Omitting `apiVersion` in `@sanity/client` falls back to `v1`.
2. Validate documents against the schema yourself before an HTTP write, or run `sanity documents validate` afterwards. The Content Lake does not enforce schema rules.
3. Back off on 429 for mutations yourself. `@sanity/client` retries queries five times but never retries mutations. The limit is 25 mutations a second per IP.
4. Over MCP, call `create_version` before `patch_documents` when editing inside a release, then patch the returned version ID with the same `releaseId`.
5. Use GROQ projections and slices to size results. MCP query responses are limited to 64 KiB, and a blocked Free project answers 402 with `plan_limit_reached`.
