cpp11 vs Sanity

cpp11 vs Sanity: at a glance
What is cpp11?
cpp11 has spent two years rebuilding itself on R's supported API surface
cpp11 is the header-only C++ interface for R packages, and nearly every release in this window is governed by one force: R core's tightening of what counts as non-API. 0.5.0 removed the growable-vector internals that made push_back() cheap, 0.5.3 and 0.5.4 removed further non-API usage, and the small releases in between are crash and compiler-warning fixes.
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.

cpp11 has spent two years rebuilding itself on R's supported API surface
◆ Current state
cpp11 is the header-only C++ interface for R packages, and nearly every release in this window is governed by one force: R core's tightening of what counts as non-API. 0.5.0 removed the growable-vector internals that made push_back() cheap, 0.5.3 and 0.5.4 removed further non-API usage, and the small releases in between are crash and compiler-warning fixes.
◆ Where it's heading
The package is trading a little performance for the right to keep passing CRAN checks indefinitely, and saying so plainly in the release notes. With R >= 4.0 now required, whole compatibility branches have been deleted rather than maintained. The remaining work is narrow: finish the non-API migration, then get back to interface features like cpp_source() handling multiple files.
◆ Prediction
Expect the last non-API dependencies to be cleared and the deprecated compatibility defines to be removed outright; the entries suggest maintenance discipline rather than new C++ surface.
Sanity
7.5DEVOPS
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.
