Mailu vs Zoho Cliq
A side-by-side editorial comparison of Mailu and Zoho Cliq — release velocity, themes, recent moves, and the top alternatives to consider.
Mailu vs Zoho Cliq: at a glance
What is Mailu?
Mailu ships one pinned release per issue, and most of them are Roundcube's.
The 2024.06 branch releases on demand: an issue or PR comes in, a pinned version goes out, and the changelog is one or two lines. Four of the six most recent releases are webmail-driven — three Roundcube bumps in this window alone, the latest to 1.6.18 clearing a TLS-configuration warning, an earlier one to 1.6.17 closing two CVEs. The remainder are Mailu's own code: an X-Forwarded-By header fix tied to a published advisory, sieve field escaping that repaired autoreplies and closed an injection path, and two admin-UI form flow corrections.
What is Zoho Cliq?
Zoho Cliq 7.0 bets on AI conversation summaries and Neat hardware to close the gap with enterprise messaging platforms
Zoho Cliq is mid-cycle on its most substantial release in years. Cliq 7.0 (August 2026) introduced AI-powered thread summaries, automatic task extraction from conversations, voice transcription with AI notes, and a redesigned developer platform. The guest user feature was overhauled for external collaboration, and the product now runs natively on Neat conferencing hardware — moving from software into physical meeting rooms.

◆ Current state
The 2024.06 branch releases on demand: an issue or PR comes in, a pinned version goes out, and the changelog is one or two lines. Four of the six most recent releases are webmail-driven — three Roundcube bumps in this window alone, the latest to 1.6.18 clearing a TLS-configuration warning, an earlier one to 1.6.17 closing two CVEs. The remainder are Mailu's own code: an X-Forwarded-By header fix tied to a published advisory, sieve field escaping that repaired autoreplies and closed an injection path, and two admin-UI form flow corrections.
◆ Where it's heading
This is a maintenance branch behaving exactly as a maintenance branch should, and the pinned-version model is the product: operators get upstream security work packaged and tagged without tracking Roundcube themselves. The security items divide cleanly — most arrive from bundled components, a minority from Mailu's own code, and the project patches both on the same cadence. Nothing in this window suggests new capability is being developed on this branch.
◆ Prediction
Expect the next release to follow the same trigger: a Roundcube advisory or a client compatibility report producing a single-line changelog and a new pinned tag. Any feature work would be happening on the main version, which this feed does not cover.
Zoho Cliq
6.3COMMS
Zoho Cliq 7.0 bets on AI conversation summaries and Neat hardware to close the gap with enterprise messaging platforms
◆ Current state
Zoho Cliq is mid-cycle on its most substantial release in years. Cliq 7.0 (August 2026) introduced AI-powered thread summaries, automatic task extraction from conversations, voice transcription with AI notes, and a redesigned developer platform. The guest user feature was overhauled for external collaboration, and the product now runs natively on Neat conferencing hardware — moving from software into physical meeting rooms.
◆ Where it's heading
Cliq is running a dual-layer play: embed Zia AI deeply enough in conversations that task tracking happens inside the messaging layer rather than alongside it, while simultaneously opening to the agentic ecosystem through MCP integration and a more accessible developer platform. The Neat hardware integration points toward a longer-term push for enterprise room-system budgets, typically owned by IT rather than team leads.
◆ Prediction
Expect deeper Zia integration within the Cliq developer platform — bots triggered by conversation context rather than scheduled tasks. The MCP path suggests Cliq is positioning itself as a target for external AI agents, not just a source of data for them.
