Liquidsoap vs SurveyJS
A side-by-side editorial comparison of Liquidsoap and SurveyJS — release velocity, themes, recent moves, and the top alternatives to consider.
Liquidsoap vs SurveyJS: at a glance
What is Liquidsoap?
Liquidsoap opens its 2.5 line with subtitles as a first-class content type and a streaming server of its own
The 2.5.x rolling release carries the accumulated 2.5.0 changelog, and it is the largest body of work Liquidsoap has staged in over a year. Subtitles become a dedicated content type alongside audio and video, with native SRT decoding, FFmpeg subtitle encode and decode, bitmap passthrough, callbacks, transformations and dynamic insertion. An Icecast-compatible server ships as icecast.server, with source authentication, mount points, relay and per-listener encoding. Underneath, the source composition model was rewritten: switch, fallback, rotate and random drop their parallel list parameters for per-source methods, and switching now fades by default.
What is SurveyJS?
SurveyJS ships a silent stable line while v3 rebuilds its rendering on theme adapters.
SurveyJS publishes two streams into the same feed. The v1.12.x stable line releases roughly weekly with notes that say nothing beyond the version number and a CI skip marker, so the changelog carries no information about what shipped. The v3.0.0 beta line is where the visible work is, and it is a rendering and theming rewrite: theme adapters, a shadcn adapter, tokens for dropdown menus, a refactored boolean switch with a toggle-switch variant, and repeated theme refreshes, alongside SSR hydration and responsiveness fixes.

Liquidsoap opens its 2.5 line with subtitles as a first-class content type and a streaming server of its own
◆ Current state
The 2.5.x rolling release carries the accumulated 2.5.0 changelog, and it is the largest body of work Liquidsoap has staged in over a year. Subtitles become a dedicated content type alongside audio and video, with native SRT decoding, FFmpeg subtitle encode and decode, bitmap passthrough, callbacks, transformations and dynamic insertion. An Icecast-compatible server ships as icecast.server, with source authentication, mount points, relay and per-listener encoding. Underneath, the source composition model was rewritten: switch, fallback, rotate and random drop their parallel list parameters for per-source methods, and switching now fades by default.
◆ Where it's heading
Liquidsoap is expanding on two axes at once. It is broadening what a stream can carry - subtitles are a third content modality in a system that has understood two - and it is moving up the stack from a source that feeds Icecast into something that can be the Icecast. The language work points the same way: a source(_) type for unknown content, callback release semantics, and effect-scoped clocks are the kind of changes made when scripts are getting large enough that lifetime and typing errors cost real production time.
◆ Prediction
The 2.5.0 final should follow the rolling branch within a release cycle, and the migration guide already shipped for the composition parameter changes suggests the breaking surface is considered settled. Watch whether subtitle support reaches the harbor and Icecast server paths, which the current notes do not say.
SurveyJS
5.0DEVOPS
SurveyJS ships a silent stable line while v3 rebuilds its rendering on theme adapters.
◆ Current state
SurveyJS publishes two streams into the same feed. The v1.12.x stable line releases roughly weekly with notes that say nothing beyond the version number and a CI skip marker, so the changelog carries no information about what shipped. The v3.0.0 beta line is where the visible work is, and it is a rendering and theming rewrite: theme adapters, a shadcn adapter, tokens for dropdown menus, a refactored boolean switch with a toggle-switch variant, and repeated theme refreshes, alongside SSR hydration and responsiveness fixes.
◆ Where it's heading
The v3 betas point at a component layer that can be retargeted at a host application's design system rather than shipping one look. Theme adapters plus a shadcn adapter plus CSS variable patching describe a survey renderer that adopts the surrounding app's tokens, which is a different integration story from theming a fixed widget. The betas also carry regular Merge v2 commits, so the stable line is being folded forward continuously rather than forked away from. What cannot be read from this feed is the stable line itself, whose release notes are build stamps.
◆ Prediction
The adapter work is the unfinished thread — expect further beta releases adding adapters for other component libraries before v3.0.0 leaves beta.
