DoubleTick vs Roundcube
A side-by-side editorial comparison of DoubleTick and Roundcube — release velocity, themes, recent moves, and the top alternatives to consider.
DoubleTick vs Roundcube: at a glance
What is DoubleTick?
WhatsApp-commerce blog feed is stale — newest entry is late 2024
DoubleTick's feed is WhatsApp-commerce how-to content — CRM roundups, broadcast guides, and selling tips for SMBs. Notably the entries all date to late 2024, so the crawled feed appears stale and no recent activity or changelog is visible.
What is Roundcube?
After four years, Roundcube 1.7 lands — and the release stream is otherwise all CVEs
Roundcube maintains two lines in lockstep: 1.6 as LTS and 1.7 as stable, with security fixes released to both on the same day. The vulnerability stream is heavy and varied — stored XSS via an unescaped attachment MIME type (CVE-2026-54432), a pre-auth SQL injection in the virtuser_query plugin, CSS injection through SVG animate, SSRF bypasses via local address URLs, an infinite loop in the TNEF decoder. Version 1.7.0, released in May after almost four years of development, is the only feature release in the window.

DoubleTick

WhatsApp-commerce blog feed is stale — newest entry is late 2024
◆ Current state
DoubleTick's feed is WhatsApp-commerce how-to content — CRM roundups, broadcast guides, and selling tips for SMBs. Notably the entries all date to late 2024, so the crawled feed appears stale and no recent activity or changelog is visible.
◆ Where it's heading
The content positions DoubleTick around WhatsApp marketing and sales enablement, but with no 2025 or 2026 entries the trajectory is indeterminate — either the blog stopped updating or the crawler is pointed at an archived feed.
◆ Prediction
Without fresh entries no confident prediction is possible; the feed source most likely needs re-pointing to current content.
Roundcube
5.0COMMS
After four years, Roundcube 1.7 lands — and the release stream is otherwise all CVEs
◆ Current state
Roundcube maintains two lines in lockstep: 1.6 as LTS and 1.7 as stable, with security fixes released to both on the same day. The vulnerability stream is heavy and varied — stored XSS via an unescaped attachment MIME type (CVE-2026-54432), a pre-auth SQL injection in the virtuser_query plugin, CSS injection through SVG animate, SSRF bypasses via local address URLs, an infinite loop in the TNEF decoder. Version 1.7.0, released in May after almost four years of development, is the only feature release in the window.
◆ Where it's heading
The arc is a long-lived webmail codebase paying down structural risk. 1.7.0's headline changes are defensive rather than user-facing: a mandatory public_html/ entry point so installations aren't exposed by default, improved OAuth2/OIDC support including discovery and logout, removed code bloat and automated code style and quality checks. Everything since has been paired security releases across both lines, several of them reporting classes of bug — sanitizer bypasses, injection through plugin queries — that the 1.7 hardening work is aimed at. Expect the security cadence to stay high while the 1.6 LTS remains supported.
◆ Prediction
Expect continued same-day paired security releases on 1.6 and 1.7, with 1.7.x accruing incremental OIDC and sanitizer hardening before any 1.8 work becomes visible.
