What is Gallabox?

WhatsApp-first CX tool expands into new channels and AI-built bots.

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.

Gallabox vs Stalwart: editorial side-by-side

G0.0

WhatsApp-first CX tool expands into new channels and AI-built bots.

◆ Current state

Gallabox is a WhatsApp Business messaging and CX platform that is broadening from a single-channel tool into a multi-channel inbox with AI automation. Recent releases add Voice and Instagram DMs as channels while leaning into AI-authored chatbots and team-routing features.

◆ Where it's heading

The product is heading toward an omnichannel conversation hub where WhatsApp remains the anchor but Voice, Instagram, and AI bots reduce reliance on any one surface. Much of the changelog also tracks Meta's pricing changes, which shape how customers use broadcasts.

◆ Prediction

Expect Voice and Instagram to graduate from early access/waitlist to general availability, and deeper AI-bot tooling that turns plain-language instructions into deployable agents.

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.
