What is OpenAPI Generator?

OpenAPI Generator holds a 240-change cadence across forty-odd language targets.

The project ships stable releases every four to eight weeks, each carrying 150 to 240 enhancements and fixes spread across generators for C#, Dart, Go, Java, Kotlin, C++, Crystal and dozens more. 7.25.0 follows the pattern: a parser update, restored schemaMapping imports in API interfaces, a stable input-spec hash for the Maven plugin, a way for clients to inject vendor overrides, and splitOperationsByContentType. Every recent release is labelled as carrying breaking changes with fallbacks.

What is Sanity?

Sanity's MCP server now advertises itself to agents through a server card and llms.txt.

Sanity shipped three MCP server releases in two days. 2.44.0 makes the server discoverable through a /.well-known server card, an HTML or markdown landing page, robots.txt and llms.txt, and cuts CPU per request. 2.43.0 adds an undeploy_schema tool and deprecates workspaceName for schema selection. 2.42.2 fixes validation against deployed schemas and refuses patches that would change a document's _type.

OpenAPI Generator vs Sanity: editorial side-by-side

O5.0

OpenAPI Generator holds a 240-change cadence across forty-odd language targets.

◆ Current state

The project ships stable releases every four to eight weeks, each carrying 150 to 240 enhancements and fixes spread across generators for C#, Dart, Go, Java, Kotlin, C++, Crystal and dozens more. 7.25.0 follows the pattern: a parser update, restored schemaMapping imports in API interfaces, a stable input-spec hash for the Maven plugin, a way for clients to inject vendor overrides, and splitOperationsByContentType. Every recent release is labelled as carrying breaking changes with fallbacks.

◆ Where it's heading

Two constants govern this feed. The core keeps absorbing OpenAPI 3.1 semantics - null handling, map normalisation, any-type with additional properties, allOf members alongside validation keywords - while the per-language generators take independent fixes from their own maintainers. Shipping breaking changes with fallbacks is how a project with this many downstream consumers avoids forcing coordinated upgrades, and it has held for at least six releases.

◆ Prediction

OpenAPI 3.1 normalisation has produced fixes in every release for months and is still doing so, so expect that work to continue rather than conclude.

5.0

Sanity's MCP server now advertises itself to agents through a server card and llms.txt.

◆ Current state

Sanity shipped three MCP server releases in two days. 2.44.0 makes the server discoverable through a /.well-known server card, an HTML or markdown landing page, robots.txt and llms.txt, and cuts CPU per request. 2.43.0 adds an undeploy_schema tool and deprecates workspaceName for schema selection. 2.42.2 fixes validation against deployed schemas and refuses patches that would change a document's _type.

◆ Where it's heading

The MCP server is becoming the main way agents read and write Sanity content, and the work has shifted from adding tools to making it safe and findable: guarded patches, accurate safety annotations, full schema lifecycle and discovery metadata. Studio and Manage continue alongside it with speed work and admin features for larger organizations.

◆ Prediction

Expect workspaceName to be removed after the migration period, and more guardrails on write tools such as patch_documents.
