mailcow vs Tinode: at a glance
What is mailcow?
mailcow's release notes are almost entirely upstream security currency.
mailcow ships named seasonal releases with lettered revisions, and nearly every revision exists to pull in an upstream security fix - Redis, ClamAV, SOGo, Rspamd, nginx, unbound, Postfix. Revision B of the Mooly 2026 release updates Redis 7.4.10, ClamAV 1.4.6, and SOGo 5.12.10, adds minor web UI and nginx hardening, and removes a legacy DeltaChat sieve rule. The last release with genuinely new features was the March cut, which added forced 2FA, ACME DNS-01 challenges, and a passwordless autodiscover endpoint.
What is Tinode?
An open-source chat server in steady maintenance while reactions sit in alpha
Tinode's release stream is dominated by dependency upgrades and bug fixes across the 0.25.x line — a gRPC auth-level fix, the Postgres driver moved to v5, AWS to v2. The last substantive user-facing work was pinned chats, subscriber counts and a system-default UI mode in late 2025. A 0.26.0 alpha exists on a reactions branch but has not converged.
mailcow vs Tinode: editorial side-by-side
mailcow
5.0COMMS
mailcow's release notes are almost entirely upstream security currency.
◆ Current state
mailcow ships named seasonal releases with lettered revisions, and nearly every revision exists to pull in an upstream security fix - Redis, ClamAV, SOGo, Rspamd, nginx, unbound, Postfix. Revision B of the Mooly 2026 release updates Redis 7.4.10, ClamAV 1.4.6, and SOGo 5.12.10, adds minor web UI and nginx hardening, and removes a legacy DeltaChat sieve rule. The last release with genuinely new features was the March cut, which added forced 2FA, ACME DNS-01 challenges, and a passwordless autodiscover endpoint.
◆ Where it's heading
For a self-hosted mail stack that bundles a dozen upstream components, keeping current with their CVEs is the product, and mailcow has organized its release cadence around exactly that. The pattern is consistent: a named release with some feature content every few months, then lettered revisions that are pure security currency plus small web UI escaping and validation fixes. The web interface is where mailcow's own code gets hardened - HTML escaping in quarantine views and sieve editors recurs across several revisions.
◆ Prediction
Expect the next entry to be another lettered revision carrying upstream updates, with the next named release likely bundling whatever feature work has accumulated since March.
Tinode
2.5COMMS
An open-source chat server in steady maintenance while reactions sit in alpha
◆ Current state
Tinode's release stream is dominated by dependency upgrades and bug fixes across the 0.25.x line — a gRPC auth-level fix, the Postgres driver moved to v5, AWS to v2. The last substantive user-facing work was pinned chats, subscriber counts and a system-default UI mode in late 2025. A 0.26.0 alpha exists on a reactions branch but has not converged.
◆ Where it's heading
Development is consolidation-shaped: the maintainers are keeping the 0.25 line current and correct rather than opening new surface. Performance work in push dispatch and intra-cluster buffers suggests attention on deployments running at size. The reactions branch is the only visible feature bet, and it has been in alpha since January.
◆ Prediction
The next meaningful release is most likely 0.26.0 carrying reactions out of alpha, but the alpha has sat untouched in the window, so a date is not something the entries support.
