Fiber vs Sanity
A side-by-side editorial comparison of Fiber and Sanity — release velocity, themes, recent moves, and the top alternatives to consider.
Fiber vs Sanity: at a glance
What is Fiber?
Fiber v3 has sat in release candidate for months while v2 gets security fixes only
Fiber's v2 line is receiving nothing but small security and correctness work — an HTML escaping fix in Ctx.Format, a CVE fix, defensive copying backports, limiter middleware repairs, and a backported X-Real-IP overwrite fix in the load balancer. Meanwhile v3.0.0-rc.3, the last release candidate visible here, carries all the actual feature work: native net/http and fasthttp handler support, Express-style request and response handlers, HostClient and LBClient, and HTTP 501 handling for unsupported methods.
What is Sanity?
Sanity is making everything outside the Studio - apps, media, roles - a first-class surface.
Sanity ships continuously across five distinct surfaces: Studio, the React App SDK, Media Library, Manage, and the MCP server, each on its own version line. The last two weeks are dominated by non-Studio work - bidirectional presence for custom apps, a redesigned Media Library grid with original-video storage, a visual builder for custom-role filters, and Shopify metafield sync. Studio's own releases in the window are almost entirely bugfix and stability work, now three consecutive minors deep.

◆ Current state
Fiber's v2 line is receiving nothing but small security and correctness work — an HTML escaping fix in Ctx.Format, a CVE fix, defensive copying backports, limiter middleware repairs, and a backported X-Real-IP overwrite fix in the load balancer. Meanwhile v3.0.0-rc.3, the last release candidate visible here, carries all the actual feature work: native net/http and fasthttp handler support, Express-style request and response handlers, HostClient and LBClient, and HTTP 501 handling for unsupported methods.
◆ Where it's heading
The split is unusually stark. Every capability that would change how Fiber is used sits behind a v3 candidate that has not moved forward in this window, while v2 — what almost everyone actually runs — gets only fixes. The v3 feature list points at a clear thesis, making Fiber interoperable with the standard library rather than an island, but that thesis is not yet available to users on a stable release.
◆ Prediction
The entries do not show a v3 release approaching; on the visible evidence, expect v2 to keep receiving security backports and the net/http interop work to remain candidate-only until the release cadence resumes.
Sanity
5.0DEVOPS
Sanity is making everything outside the Studio - apps, media, roles - a first-class surface.
◆ Current state
Sanity ships continuously across five distinct surfaces: Studio, the React App SDK, Media Library, Manage, and the MCP server, each on its own version line. The last two weeks are dominated by non-Studio work - bidirectional presence for custom apps, a redesigned Media Library grid with original-video storage, a visual builder for custom-role filters, and Shopify metafield sync. Studio's own releases in the window are almost entirely bugfix and stability work, now three consecutive minors deep.
◆ Where it's heading
The center of gravity is shifting from the Studio as the place you edit content to a platform where your own app is a peer participant. Presence becoming writable from the SDK is the clearest signal: a third-party app can now appear in the same collaboration session as Studio users rather than silently observing. Media Library and Manage are being built out with the polish and governance features enterprise buyers evaluate, while the Studio line spends its releases hardening the structure tool and CLI that everything else sits on.
◆ Prediction
Expect more Studio capabilities to be re-exposed through the App SDK write side, so the next releases likely extend the same pattern to tasks, comments, or release state.
