Stalwart vs Zoho Cliq: at a glance
What is Stalwart?
Stalwart adds full SCIM v2 provisioning and 24-language calendar support as its standards coverage extends further than most commercial mail servers.
Stalwart is maintaining a weekly-or-faster release cadence, with alternating feature releases and dense bug-fix releases. The v0.16.20 release landed full SCIM v2 (Enterprise) including cursor-based pagination and the IPSIE lifecycle profile, conference links in calendar invites, and 24 new calendar interface translations. Below the feature line, the project is steadily closing correctness gaps across JMAP, CalDAV, IMAP, and MTA — many of them edge-case RFC compliance issues.
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.

Stalwart
6.3COMMS
Stalwart adds full SCIM v2 provisioning and 24-language calendar support as its standards coverage extends further than most commercial mail servers.
◆ Current state
Stalwart is maintaining a weekly-or-faster release cadence, with alternating feature releases and dense bug-fix releases. The v0.16.20 release landed full SCIM v2 (Enterprise) including cursor-based pagination and the IPSIE lifecycle profile, conference links in calendar invites, and 24 new calendar interface translations. Below the feature line, the project is steadily closing correctness gaps across JMAP, CalDAV, IMAP, and MTA — many of them edge-case RFC compliance issues.
◆ Where it's heading
Stalwart is building toward parity with commercial enterprise mail servers on identity federation and provisioning (SCIM v2, VAPID for web push, DMARCbis/DKIM2 already landed). The pace of RFC implementation is unusually aggressive for an open-source project; the combination of JMAP, CalDAV, IMAP UIDONLY/UIDBATCHES, and SCIM v2 positions it as a viable self-hosted alternative for organizations that need standards compliance without vendor lock-in.
◆ Prediction
WebAuthn/passkey-based authentication and improved multi-tenant administration tooling are the most likely next capability additions, given the current trajectory toward enterprise identity management.
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.
