What is Echo?

Echo is running two lines in lockstep, and security is what triggers releases

Echo maintains v4 and v5 in parallel and treats security parity as non-negotiable — both of the vulnerabilities in this window were fixed on v5 and backported to v4 within hours. The issues themselves are the same class twice over: values taken from request headers and paths being trusted too readily. Context.Scheme accepted malformed forwarded scheme values, and encoded path separators in static file URLs could bypass route-level middleware and disclose files.

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.

Echo is running two lines in lockstep, and security is what triggers releases

◆ Current state

Echo maintains v4 and v5 in parallel and treats security parity as non-negotiable — both of the vulnerabilities in this window were fixed on v5 and backported to v4 within hours. The issues themselves are the same class twice over: values taken from request headers and paths being trusted too readily. Context.Scheme accepted malformed forwarded scheme values, and encoded path separators in static file URLs could bypass route-level middleware and disclose files.

◆ Where it's heading

The pattern that matters is where each vulnerability lived: both sat in code that decides what a request is, before any application logic runs, which is where a web framework's security surface actually is. Feature work is confined to v5 — an optional rate-limiter store context for response headers, core hot-path optimisation — while v4 receives security fixes only, a clean maintenance split with no ambiguity about which line is current.

◆ Prediction

Expect v5 to keep taking the middleware and performance work while v4 continues receiving same-day security backports, and further hardening around path and header parsing given that two reported issues in a row landed there.

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.
