What is Smartsupp?

Smartsupp keeps compounding its Mira AI shopping assistant

Smartsupp's updates are a steady build-out of its Mira AI shopping assistant and live chat: one-click conversation translation, product cards pulled from the merchant feed, richer AI-response formatting, automatic website-content refresh, and full-context awareness so Mira stops asking for details it can look up. A compact chat-box header is the lone cosmetic item.

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.

Smartsupp vs Stalwart: editorial side-by-side

S2.5

Smartsupp keeps compounding its Mira AI shopping assistant

◆ Current state

Smartsupp's updates are a steady build-out of its Mira AI shopping assistant and live chat: one-click conversation translation, product cards pulled from the merchant feed, richer AI-response formatting, automatic website-content refresh, and full-context awareness so Mira stops asking for details it can look up. A compact chat-box header is the lone cosmetic item.

◆ Where it's heading

The direction is a more autonomous, context-aware commerce assistant, grounding Mira in the merchant's own feed and site, cutting manual setup, and smoothing multilingual support. Each release is incremental, but together they push Smartsupp from live chat toward an AI-first shopping layer.

◆ Prediction

Expect further Mira grounding and autonomy, with more automatic data sourcing and richer in-chat commerce as the product-card work points toward deeper catalog actions. Multilingual support looks set to widen.

S6.3

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.
