Roundcube vs Whereby
A side-by-side editorial comparison of Roundcube and Whereby — release velocity, themes, recent moves, and the top alternatives to consider.
Roundcube vs Whereby: at a glance
What is Roundcube?
Roundcube's October release patches 13 more holes on both branches at once.
Roundcube shipped 1.7.5 and 1.6.20 on 19 October, again as a matched pair, fixing IMAP command injection via the _uid parameter, mail header injection in bounce and reply paths, a session object-injection primitive, ImageMagick limits bypasses, an SSRF filter bypass via NAT64 and several remote-content blocking bypasses. It is the fifth paired security release since June.
What is Whereby?
Whereby folds three months into one digest and still lists nothing specific
Whereby's latest entry covers August through October in a single round-up, again framed around developer experience and SDKs, with no concrete features in the feed text. The last specific capabilities visible are session ratings for Embedded customers in April and the native iOS SDK leaving beta in February.

Roundcube
5.0COMMS
Roundcube's October release patches 13 more holes on both branches at once.
◆ Current state
Roundcube shipped 1.7.5 and 1.6.20 on 19 October, again as a matched pair, fixing IMAP command injection via the _uid parameter, mail header injection in bounce and reply paths, a session object-injection primitive, ImageMagick limits bypasses, an SSRF filter bypass via NAT64 and several remote-content blocking bypasses. It is the fifth paired security release since June.
◆ Where it's heading
Monthly security releases on both the 1.7 and LTS 1.6 lines have become the product's main output, driven by outside researchers. Several fixes revisit earlier ones, such as CSS-escape blocking bypasses fixed 'again', which suggests the content-sanitising code is still being mapped.
◆ Prediction
Another paired 1.7.x and 1.6.x security release in about a month is the pattern; feature work isn't visible in these entries.

Whereby folds three months into one digest and still lists nothing specific
◆ Current state
Whereby's latest entry covers August through October in a single round-up, again framed around developer experience and SDKs, with no concrete features in the feed text. The last specific capabilities visible are session ratings for Embedded customers in April and the native iOS SDK leaving beta in February.
◆ Where it's heading
The cadence is slowing: monthly digests have become a quarterly one, and the framing remains aimed at developers embedding video rather than meeting hosts. Without specifics in the notes, the direction can only be read from the framing, which points at SDK and embedding work.
◆ Prediction
The next entry is most likely another multi-month SDK round-up; the feed gives no signal of a larger launch.
