What is Intercom?

Fin crossed from deflecting tickets to closing sales inside Shopify stores.

The notable move is Fin working the pre-sale conversation on Shopify storefronts — answering shopper questions, recommending products and guiding checkout. The rest is disciplined helpdesk work: workflow version history and rollback, custom redaction rules, SLA-based sorting, required ticket attributes on close, in-place ticket type changes, Round Robin coverage when teammates are away, Discord as an inbox channel, and default outbound numbers for voice.

What is Stalwart?

Stalwart is shipping email's next-generation auth stack while the specs are still in draft.

Stalwart is an all-in-one mail and collaboration server — SMTP, IMAP, JMAP, CalDAV, CardDAV and WebDAV in one binary — releasing every one to two weeks on the 0.16.x line. The last two months read as a standards campaign: DKIM2 and the full DMARCbis set in 0.16.12, VAPID push in 0.16.14, FreeBSD support in 0.16.13, and a run of IMAP extensions (UIDONLY, UIDBATCHES, MESSAGELIMIT/SAVELIMIT) in 0.16.17. Between the additions, most of each release is JMAP conformance repair driven by the jmap-test-suite.

Intercom vs Stalwart: editorial side-by-side

Intercom logo0.0

Fin crossed from deflecting tickets to closing sales inside Shopify stores.

◆ Current state

The notable move is Fin working the pre-sale conversation on Shopify storefronts — answering shopper questions, recommending products and guiding checkout. The rest is disciplined helpdesk work: workflow version history and rollback, custom redaction rules, SLA-based sorting, required ticket attributes on close, in-place ticket type changes, Round Robin coverage when teammates are away, Discord as an inbox channel, and default outbound numbers for voice.

◆ Where it's heading

Two tracks running at once. The agent is being pointed at revenue rather than only cost, while the human-facing inbox gets steadily more governable — versioned workflows, enforced attributes, redaction, SLA visibility. The second track is what makes the first sellable into larger accounts.

◆ Prediction

Expect Fin's commerce role to extend past Shopify to other storefronts, and the governance work to follow it — controls over what the agent may recommend or promise.

S5.0

Stalwart is shipping email's next-generation auth stack while the specs are still in draft.

◆ Current state

Stalwart is an all-in-one mail and collaboration server — SMTP, IMAP, JMAP, CalDAV, CardDAV and WebDAV in one binary — releasing every one to two weeks on the 0.16.x line. The last two months read as a standards campaign: DKIM2 and the full DMARCbis set in 0.16.12, VAPID push in 0.16.14, FreeBSD support in 0.16.13, and a run of IMAP extensions (UIDONLY, UIDBATCHES, MESSAGELIMIT/SAVELIMIT) in 0.16.17. Between the additions, most of each release is JMAP conformance repair driven by the jmap-test-suite.

◆ Where it's heading

The project is building toward being the reference implementation of the modern mail stack — JMAP first, with the classic protocols held at parity rather than left behind. The fix lists have shifted in character over these eight releases: less "feature does not work", more "spec detail is wrong", which is what a codebase looks like as it converges on conformance. Security and multi-tenancy fixes keep appearing alongside the protocol work, indicating real deployments are exercising the newer subsystems.

◆ Prediction

The next releases most likely track revisions to the drafts already implemented — DKIM2, JMAP push and the calendar drafts are all still moving — rather than adding another protocol surface. Expect continued JMAP conformance fixes until the test suite stops producing them.
