What is Smartsupp?
Mira AI is Smartsupp's center of gravity — formatting, context and live website ingestion compound toward a real shopping agent.
Smartsupp's release stream is dominated by Mira AI, the in-product shopping assistant. Recent work makes Mira's responses better-formatted, gives her continuous refresh access to website content (not just product feeds), and adds full-conversation context so she stops re-asking questions already answered. The non-AI surface — chat box, live-chat side — gets accessibility (WCAG 2.1 AA) and message-formatting wins, but the build energy is clearly on AI.
What is Stalwart?
Stalwart keeps hardening its mail server with standards conformance and at-rest encryption.
Stalwart is an open-source all-in-one mail and collaboration server (JMAP, IMAP, SMTP). Recent releases focus on standards conformance and security hardening: passing the JMAP test suite, adding IMAP and OAuth protocol extensions, international domain names, and now encryption-at-rest for S/MIME. It is a steady point-release cadence aimed at correctness and interoperability.

Smartsupp
0.0COMMS
Mira AI is Smartsupp's center of gravity — formatting, context and live website ingestion compound toward a real shopping agent.
◆ Current state
Smartsupp's release stream is dominated by Mira AI, the in-product shopping assistant. Recent work makes Mira's responses better-formatted, gives her continuous refresh access to website content (not just product feeds), and adds full-conversation context so she stops re-asking questions already answered. The non-AI surface — chat box, live-chat side — gets accessibility (WCAG 2.1 AA) and message-formatting wins, but the build energy is clearly on AI.
◆ Where it's heading
Smartsupp is positioning itself as an SMB-friendly AI shopping assistant rather than a generic live-chat tool. Each release narrows the gap between Mira and human-quality e-commerce support: better recall, better presentation, fewer redundant questions. That puts the product more directly in competition with Tidio AI, Gorgias and Shopify's native chatbots than with traditional live-chat vendors.
◆ Prediction
Expect AI-to-agent handoff with summary continuity, conversion-attribution metrics tied to Mira interactions, and tighter Shopify and WooCommerce hooks so Mira can act on cart and checkout state, not just describe products.
Stalwart
5.0COMMS
Stalwart keeps hardening its mail server with standards conformance and at-rest encryption.
◆ Current state
Stalwart is an open-source all-in-one mail and collaboration server (JMAP, IMAP, SMTP). Recent releases focus on standards conformance and security hardening: passing the JMAP test suite, adding IMAP and OAuth protocol extensions, international domain names, and now encryption-at-rest for S/MIME. It is a steady point-release cadence aimed at correctness and interoperability.
◆ Where it's heading
The work points toward production maturity: closing JMAP spec gaps, adding high-availability primitives (Redis Sentinel coordination), and tightening TLS, DANE, and encryption. Stalwart is positioning itself as a standards-faithful, deployable alternative to legacy mail stacks rather than chasing new user-facing features.
◆ Prediction
Expect continued point releases that finish protocol conformance and expand operational features—high-availability backends, certificate handling, and encryption options—rather than a major feature pivot.
