Fiber vs SurveyJS
A side-by-side editorial comparison of Fiber and SurveyJS — release velocity, themes, recent moves, and the top alternatives to consider.
Fiber vs SurveyJS: 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 SurveyJS?
SurveyJS runs a silent maintenance train while v3 is rebuilt in the open.
Two trains are visible. The v1.12.x line ships every week or two with release notes consisting of nothing but the version number and a CI skip marker, so what changed is only discoverable from the repository. The v3.0.0 beta line is the opposite: long PR lists showing a theming system being rebuilt — theme adapters, component radius CSS variables, design tokens for dropdowns and toggle switches, progress UI state.

Fiber v3 has sat in release candidate for months while v2 gets security fixes only
◆ 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.
SurveyJS
5.0DEVOPS
SurveyJS runs a silent maintenance train while v3 is rebuilt in the open.
◆ Current state
Two trains are visible. The v1.12.x line ships every week or two with release notes consisting of nothing but the version number and a CI skip marker, so what changed is only discoverable from the repository. The v3.0.0 beta line is the opposite: long PR lists showing a theming system being rebuilt — theme adapters, component radius CSS variables, design tokens for dropdowns and toggle switches, progress UI state.
◆ Where it's heading
v3 is a presentation-layer overhaul rather than a functional one, judging by where the PRs land: styling, tokens, theme adapters, and a steady stream of creator-side ticket references. The v1.12 train exists to keep existing embedders patched while that work continues.
◆ Prediction
Expect the beta series to continue until the theming and token work stabilises, and the v1.12.x releases to stay contentless — reading this product's actual changes requires the repository, not the release feed.
