Maddy vs Rocket.Chat: at a glance
What is Maddy?
A one-binary mail server learning to behave like production infrastructure.
maddy is an all-in-one SMTP and IMAP server written in Go, aimed at people who want a working mail host without assembling Postfix, Dovecot and a policy daemon themselves. The 0.9 line moved quickly — 0.9.0 through 0.9.5 between late March and late May — with the sequence following a recognisable shape: a feature release, an immediate patch for a broken integration, a security release, then cleanup. Configuration is directive-based, and much of the changelog concerns the behaviour of individual modules like auth.ldap, check.rspamd and check.dnsbl.
What is Rocket.Chat?
Rocket.Chat finishes the 8.8 calling work while the licence wall for SSO gets a date.
The 8.8 candidate line is winding down. rc.2 is a bare Meteor version bump with no user-visible change, following rc.1 which promoted Voice Call Screen Sharing to stable and turned on the in-room call interface for every call, screen sharing available or not, alongside repairs to a message list that could quietly load a whole room's history in the background. The release that still defines the line is rc.0: LDAP and SAML deprecated on non-Premium workspaces with 9.0.0 named as the cutoff, forced end-to-end encryption for new private rooms, classification banners for ABAC-managed rooms, and the apps-engine default runtime moved from Deno to Node.

Maddy
0.0COMMS
A one-binary mail server learning to behave like production infrastructure.
◆ Current state
maddy is an all-in-one SMTP and IMAP server written in Go, aimed at people who want a working mail host without assembling Postfix, Dovecot and a policy daemon themselves. The 0.9 line moved quickly — 0.9.0 through 0.9.5 between late March and late May — with the sequence following a recognisable shape: a feature release, an immediate patch for a broken integration, a security release, then cleanup. Configuration is directive-based, and much of the changelog concerns the behaviour of individual modules like auth.ldap, check.rspamd and check.dnsbl.
◆ Where it's heading
The project is systematically removing the compromises that made early versions convenient. Obsolete SASL LOGIN was disabled by default, the STARTTLS plaintext fallback was dropped, the maddyctl symlink behaviour and the implicit run command were deleted after four years of deprecation warnings, and libdns providers that have not kept up with 1.x are being cut. Running the other way is operational maturity: no-downtime config reload, queue-length metrics, OpenMetrics fixes, systemd readiness reporting, and SLSA build attestations on release artifacts. This is a project moving from hobbyist-friendly to operator-friendly, and accepting breakage to get there.
◆ Prediction
0.10.0 is already scoped by the deprecations announced in 0.9.1 — expect the flagged libdns providers to be removed and gandi to require Bearer tokens. Given the 0.9.x pattern, a feature release followed quickly by an integration fix is the likely shape.
Rocket.Chat
6.3COMMS
Rocket.Chat finishes the 8.8 calling work while the licence wall for SSO gets a date.
◆ Current state
The 8.8 candidate line is winding down. rc.2 is a bare Meteor version bump with no user-visible change, following rc.1 which promoted Voice Call Screen Sharing to stable and turned on the in-room call interface for every call, screen sharing available or not, alongside repairs to a message list that could quietly load a whole room's history in the background. The release that still defines the line is rc.0: LDAP and SAML deprecated on non-Premium workspaces with 9.0.0 named as the cutoff, forced end-to-end encryption for new private rooms, classification banners for ABAC-managed rooms, and the apps-engine default runtime moved from Deno to Node.
◆ Where it's heading
Two threads run at once and point in different directions. The calling stack keeps maturing on its own — voice, then screen sharing, now a consistent in-room surface for both — which is Rocket.Chat absorbing functions its users would otherwise reach for a separate tool to get. Against that, the 9.0 licence requirement for LDAP and SAML sorts the install base: regulated and government deployments that will pay, and unlicensed self-hosted workspaces that were there for the absence of a per-seat bill. The rc train itself has settled into a familiar shape, one substantive rc.0 followed by bumps and fixes.
◆ Prediction
Expect 8.8 to go final once the message-list fixes settle, with the LDAP and SAML licence requirement, not any calling feature, as the story of 9.0. The open question is whether the Deno-to-Node runtime switch surfaces app compatibility reports before then.
