What is Sanity?

Sanity ships across every package at once, and the agent-facing surface moves fastest.

Sanity releases as a fleet: MCP server, Studio, JavaScript client, Media Library and UI all cut versions within days of each other, and the changelog reads as one stream of package releases. The current window is dominated by two lanes — the MCP server steadily gaining tools agents can call, and a round of modernization breakage in the client libraries (ESM-only, Node 22.12 floor). Studio v6.10.0 now bundles the App SDK, so custom Studio tools can call SDK hooks without wiring their own provider.

What is Vitest?

Vitest 5 is in bug-fix mode: the second RC is almost entirely hardening

rc.2 carries one feature — a custom title for the GitHub Actions summary — and otherwise fixes the failure modes the RC period surfaced. The browser mode gets most of it: failing instead of hanging when the browser stops responding, exiting cleanly on disconnect during cancellation, and triggering Chromium GC when disk runs low. Snapshot evaluation moved server-side to work under a no-unsafe-eval CSP, and the UI now requires auth for coverage reports and every subtree request.

Sanity vs Vitest: editorial side-by-side

S
Sanity
DEVOPS
7.5

Sanity ships across every package at once, and the agent-facing surface moves fastest.

◆ Current state

Sanity releases as a fleet: MCP server, Studio, JavaScript client, Media Library and UI all cut versions within days of each other, and the changelog reads as one stream of package releases. The current window is dominated by two lanes — the MCP server steadily gaining tools agents can call, and a round of modernization breakage in the client libraries (ESM-only, Node 22.12 floor). Studio v6.10.0 now bundles the App SDK, so custom Studio tools can call SDK hooks without wiring their own provider.

◆ Where it's heading

The MCP server is where the capability surface is actually growing — asset upload, schema discovery, CORS management — each release handing agents another operation that previously needed a human in the dashboard. The library work underneath is consolidation: one module system, one supported Node line, fewer dependencies, and now one SDK shared between Studio extensions and standalone apps. Read together, Sanity is narrowing the number of ways to build against it while widening what an agent can do unattended.

◆ Prediction

Expect the MCP tool list to keep absorbing dashboard operations — deploy, dataset and role management are the obvious remaining gaps — and the ESM-only floor to propagate to the packages that have not taken it yet. The releases are per-package, so a single dated entry rarely tells the whole story of a given week.

5.0

Vitest 5 is in bug-fix mode: the second RC is almost entirely hardening

◆ Current state

rc.2 carries one feature — a custom title for the GitHub Actions summary — and otherwise fixes the failure modes the RC period surfaced. The browser mode gets most of it: failing instead of hanging when the browser stops responding, exiting cleanly on disconnect during cancellation, and triggering Chromium GC when disk runs low. Snapshot evaluation moved server-side to work under a no-unsafe-eval CSP, and the UI now requires auth for coverage reports and every subtree request.

◆ Where it's heading

The v5 line has spent four betas and two candidates reshaping config resolution, projects, mocking defaults, and the benchmark API; this candidate adds nothing to that surface and only stabilizes it. The concentration of browser-mode and pool fixes says that is where the remaining risk sits, and where real-world RC adoption is finding edges.

◆ Prediction

On this trajectory the next tag is either a final 5.0.0 or one more candidate, with browser mode the deciding factor rather than any remaining API work.
