Misskey vs Roundcube
A side-by-side editorial comparison of Misskey and Roundcube — release velocity, themes, recent moves, and the top alternatives to consider.
Misskey vs Roundcube: at a glance
What is Misskey?
Misskey moves to Sentry v11 and keeps shipping security fixes in its monthly releases.
Misskey, the ActivityPub social server, shipped 2026.10.0 with a security fix and an HTTP Signatures fix, then 2026.10.1, which moves to Sentry SDK v11 and replaces sendDefaultPii with a dataCollection setting. The 2026.10.2 alpha improves how quote posts from Mastodon and other software display and makes the server stop safely on a bad job-queue config.
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.
Misskey vs Roundcube: editorial side-by-side
Misskey
5.0COMMS
Misskey moves to Sentry v11 and keeps shipping security fixes in its monthly releases.
◆ Current state
Misskey, the ActivityPub social server, shipped 2026.10.0 with a security fix and an HTTP Signatures fix, then 2026.10.1, which moves to Sentry SDK v11 and replaces sendDefaultPii with a dataCollection setting. The 2026.10.2 alpha improves how quote posts from Mastodon and other software display and makes the server stop safely on a bad job-queue config.
◆ Where it's heading
Each version goes through alpha and beta tags before stable, and security fixes appear in most stable releases since 2026.9.0. Federation polish, such as how other servers' quotes and signatures are handled, is the main user-facing thread.
◆ Prediction
Expect 2026.10.2 stable soon after its alpha, carrying the quote display and deck fixes, with 2026.11 alphas following on the monthly cadence.
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.
