A side-by-side editorial comparison of Maddy and Converse.js — release velocity, themes, recent moves, and the top alternatives to consider.
Maddy vs Converse.js: 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 Converse.js?
Converse.js 14 lands OMEMO:2 — the browser XMPP client catches up on modern encryption.
Converse.js reached 14.0.0 in June 2026 after a tight beta train, and the release is defined by one thing: support for OMEMO:2, the current revision of XMPP's end-to-end encryption. The surrounding work is all encryption ergonomics — per-chat encryption state remembered across chat-close and re-login, an explicit error surfaced for undecryptable messages instead of silently dropping them, the toggle hidden on untrusted devices, and original filenames preserved on encrypted image download. New PubSub API methods for create, subscribe and unsubscribe round out the release.

Maddy

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.
Converse.js
0.0COMMS
Converse.js 14 lands OMEMO:2 — the browser XMPP client catches up on modern encryption.
◆ Current state
Converse.js reached 14.0.0 in June 2026 after a tight beta train, and the release is defined by one thing: support for OMEMO:2, the current revision of XMPP's end-to-end encryption. The surrounding work is all encryption ergonomics — per-chat encryption state remembered across chat-close and re-login, an explicit error surfaced for undecryptable messages instead of silently dropping them, the toggle hidden on untrusted devices, and original filenames preserved on encrypted image download. New PubSub API methods for create, subscribe and unsubscribe round out the release.
◆ Where it's heading
The project is closing the gap between having encryption and having usable encryption. Almost every OMEMO change in this cycle is about failure modes users previously had to guess at: a silently dropped message, an encryption toggle offered where it cannot work, an abandoned bundle that never self-healed. That is the work a client does when its encryption is no longer a demo but something people depend on daily. Dropping client-compress for native browser APIs points the same way — fewer bundled dependencies in a security-sensitive path.
◆ Prediction
Expect the 14.x line to settle into interoperability fixes as OMEMO:2 meets other XMPP clients in the wild, with the new PubSub API the most likely base for the next feature layer.
