rlang vs Sanity
A side-by-side editorial comparison of rlang and Sanity — release velocity, themes, recent moves, and the top alternatives to consider.
rlang vs Sanity: at a glance
What is rlang?
rlang moved tidyeval off R's private internals and onto official C API.
rlang is at 1.3.0, which rewrote hash() to walk objects itself rather than lean on R's serialiser — fixing stability against bytecode and shrinkable vectors, at the cost of invalidating every existing hash value. The release before it closed a multi-year effort: rlang and tidyeval are now fully backed by official C APIs of R, work the notes credit to collaboration with R core.
What is Sanity?
Sanity is making the fastest path into its platform an agent typing a CLI command.
Sanity releases across many independently versioned packages at once — Studio, @sanity/ui, the MCP server, the React App SDK and Media Library — often several in the same week. Early August carried two directional moves within a day of each other: @sanity/ui v4.0.0 went ESM-only behind subpath imports, and Studio v6.9.2 shipped Sanity New, account-less project creation explicitly aimed at AI agents. The rest of the cadence is steady corrective work on Studio and Media Library.

rlang

rlang moved tidyeval off R's private internals and onto official C API.
◆ Current state
rlang is at 1.3.0, which rewrote hash() to walk objects itself rather than lean on R's serialiser — fixing stability against bytecode and shrinkable vectors, at the cost of invalidating every existing hash value. The release before it closed a multi-year effort: rlang and tidyeval are now fully backed by official C APIs of R, work the notes credit to collaboration with R core.
◆ Where it's heading
The through-line across this whole window is one migration. Release after release retires something that depended on private R internals — env_browse(), env_unlock(), ns_registry_env(), the SEXP iterator now behind a compile flag — and replaces it with sanctioned API. The hash() rewrite in 1.3.0 is the same instinct applied to the serialiser: own the behaviour rather than inherit it.
◆ Prediction
With the C API migration declared complete in 1.2.0, the next releases are likely to be ordinary maintenance and type-checking additions rather than further defunct markings.
Sanity
7.5DEVOPS
Sanity is making the fastest path into its platform an agent typing a CLI command.
◆ Current state
Sanity releases across many independently versioned packages at once — Studio, @sanity/ui, the MCP server, the React App SDK and Media Library — often several in the same week. Early August carried two directional moves within a day of each other: @sanity/ui v4.0.0 went ESM-only behind subpath imports, and Studio v6.9.2 shipped Sanity New, account-less project creation explicitly aimed at AI agents. The rest of the cadence is steady corrective work on Studio and Media Library.
◆ Where it's heading
Two currents run in parallel. The platform is being made agent-addressable: the MCP server can now run Sanity CLI commands without a shell, patches documents transactionally, and refuses to write to Studio-managed schemas, while project creation itself no longer requires an account. At the same time the front-end stack is being modernized without much regard for laggards — ESM-only, Node.js 22.12, React 19.2, styles as an imported stylesheet, deprecated APIs removed outright. Sanity is optimizing for teams and agents starting fresh rather than for consumers pinned to old toolchains.
◆ Prediction
Sanity New issues temporary credentials with a 72-hour window before a project must be claimed, and the MCP server is iterating weekly; the observable pattern points to the claim-and-expiry flow and the MCP schema guardrails being the next pieces to firm up. Whether agent-created projects convert into paid ones is not something these entries show.
