Userback vs Shuffle
A side-by-side editorial comparison of Userback and Shuffle — release velocity, themes, recent moves, and the top alternatives to consider.
Userback vs Shuffle: at a glance
What is Userback?
Userback's Sites turn out to be a multi-site workspace, and the first follow-up targets agencies.
Userback has spent 2026 widening where feedback comes from (mobile SDK, Slack, mobile surveys) and adding an AI layer on top (Insights themes, video transcription, AI Context Search). The October 28 follow-up finally shows what Sites is: a per-site container with its own Site Key, settings, widget and feedback list. The new tools are prefixed readable feedback IDs that pass through to Jira, copying widget settings between Sites, open-feedback counts on the Sites page, and survey targeting by query string and hash.
What is Shuffle?
Shuffle tags builds almost daily, but the notes are empty.
Shuffle has tagged six 2.3.1 builds since November 3: release candidates 4 to 6 and three nightly builds. Only rc4 lists a change, a fix for a frontend crash; the rest link to commit comparisons. The more substantive rc1 in October handled AI agent actions in hybrid worker setups.

◆ Current state
Userback has spent 2026 widening where feedback comes from (mobile SDK, Slack, mobile surveys) and adding an AI layer on top (Insights themes, video transcription, AI Context Search). The October 28 follow-up finally shows what Sites is: a per-site container with its own Site Key, settings, widget and feedback list. The new tools are prefixed readable feedback IDs that pass through to Jira, copying widget settings between Sites, open-feedback counts on the Sites page, and survey targeting by query string and hash.
◆ Where it's heading
Sites moves Userback toward running many properties from one account. Copying widget settings and sorting Sites by open feedback are built for agencies with a Site per client. The readable IDs that travel into Jira and other integrations show the same push seen in the 'Sent to Integrations' filter: making Userback the traceable start of a ticket, not a separate inbox.
◆ Prediction
Expect more cross-Site tooling, such as copying integrations or templates between Sites, since the October 28 notes say integrations still have to be set up per Site.
Shuffle
5.0INFRA · APIS
Shuffle tags builds almost daily, but the notes are empty.
◆ Current state
Shuffle has tagged six 2.3.1 builds since November 3: release candidates 4 to 6 and three nightly builds. Only rc4 lists a change, a fix for a frontend crash; the rest link to commit comparisons. The more substantive rc1 in October handled AI agent actions in hybrid worker setups.
◆ Where it's heading
The project is iterating toward 2.3.1 with frequent builds, and the October notes show the work is about making AI agent steps run reliably in workflows. The empty release notes make it hard to see what each build changes.
◆ Prediction
A 2.3.1 final release looks close given the run of release candidates and nightlies, though the entries do not say what it will contain beyond fixes.
