A side-by-side editorial comparison of CoolProp and Sanity — release velocity, themes, recent moves, and the top alternatives to consider.
CoolProp 8.0 bought sub-microsecond property lookups — and shipped a desktop app alongside it.
CoolProp released 8.0.0 in June 2026 after a long 7.x period, and paired it the same day with the first signed release of a Desktop GUI that had spent two months in unsigned alphas. The library release is dense: an SVD-compressed tabular backend giving sub-microsecond per-probe evaluation in the batched path, mass-basis vapor quality across HEOS and REFPROP, Chebyshev superancillaries for the SRK and Peng-Robinson cubics, a large fluid and mixture library expansion including the 2026 ASHRAE Standard 34 blends, and thread-safety work.
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.

The project is moving on two fronts that reinforce each other: making evaluation fast enough to sit inside simulation inner loops, and putting a real application in front of engineers who previously had to write Python to use it. The new tabular backend being off by default in PropsSI says the maintainers are treating accuracy conservatively while the fast path proves out. The GUI's progression from unsigned alpha to notarized and SignPath-signed release in two months is the clearest sign it is meant as a product, not a demo.
Expect the SVDSBTL backend's default-off flag to be revisited once conformance data accumulates, and the GUI to continue on its own version line now that the signing and auto-update pipeline is live.

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.
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.
