Sanity vs xml2
A side-by-side editorial comparison of Sanity and xml2 — release velocity, themes, recent moves, and the top alternatives to consider.
Sanity vs xml2: at a glance
What is Sanity?
Sanity is widening the surface agents can act on while forcing its own packages onto modern Node.
Sanity ships on three tracks at once: Studio, the Media Library, and an MCP server that now moves faster than either. The MCP server took three releases in nine days, adding CORS-origin management and hardening how documents and schemas are written. Underneath that, the JavaScript client and the UI package both went ESM-only in the same week, raising the floor to Node 22.12 and React 19.2.
What is xml2?
xml2 relicensed to MIT, then moved its hot accessors from S3 into C
xml2 is the libxml2 binding under most R HTML and XML work, including rvest. Its release cadence is set by libxml2 versions and R CMD check, but two of the last six matter on their own: the 1.3.3 MIT relicense and the 1.3.6 dispatch rewrite that pushed the common accessors into C and dropped three dependencies.

Sanity is widening the surface agents can act on while forcing its own packages onto modern Node.
◆ Current state
Sanity ships on three tracks at once: Studio, the Media Library, and an MCP server that now moves faster than either. The MCP server took three releases in nine days, adding CORS-origin management and hardening how documents and schemas are written. Underneath that, the JavaScript client and the UI package both went ESM-only in the same week, raising the floor to Node 22.12 and React 19.2.
◆ Where it's heading
The MCP server is where the new capability is landing — each release either exposes another piece of project administration to an agent or closes a way an agent could silently corrupt state. That pairs with Sanity New, which removes signup as a precondition for provisioning. The package modernization is cleanup that clears the way rather than a destination in itself.
◆ Prediction
Expect the MCP tool surface to keep expanding toward project administration that today requires the management console or CLI, with the same pattern of returning corrective errors rather than accepting malformed agent input.

xml2 relicensed to MIT, then moved its hot accessors from S3 into C
◆ Current state
xml2 is the libxml2 binding under most R HTML and XML work, including rvest. Its release cadence is set by libxml2 versions and R CMD check, but two of the last six matter on their own: the 1.3.3 MIT relicense and the 1.3.6 dispatch rewrite that pushed the common accessors into C and dropped three dependencies.
◆ Where it's heading
This is infrastructure maintenance in the strict sense - most releases exist because the toolchain moved, not because the package did. Where the maintainers do choose the work, it goes to performance and dependency reduction rather than new API, and the surface has been essentially stable since 1.3.0.
◆ Prediction
Expect the next releases to track libxml2 compatibility and R-devel format-string warnings; new API is unlikely beyond occasional XPath accessors in the style of xml_find_int().
