Mailu vs Friendica: at a glance
What is Mailu?
A mail server whose entire visible output is patching other people's code.
Mailu is a self-hosted mail suite shipped as a Docker compose stack, and the 2024.06.x branch shown here is its maintenance line. Every release in the window is a single-issue patch — a Roundcube bump, a CVE fix, an autoconfig tweak. The cadence looks high at ten pinned releases in five months, but each carries one change.
What is Friendica?
Friendica keeps betting on being the fediverse node that speaks everyone else's protocols.
Friendica is a self-hosted decentralised social platform, released on calendar versions two or three times a year with codenames and a consistent structure: a handful of highlights, a security-fix credit, and a pointer to the changelog. The recent run — 2023.12, 2024.03, 2024.08, 2024.12, 2026.01, 2026.05 — shows the cadence thinning, with a full year between 2024.12 and 2026.01. Nearly every release credits externally reported security issues, most recently from Doyensec working with Mastodon.
Mailu vs Friendica: editorial side-by-side
Mailu
5.0COMMS
A mail server whose entire visible output is patching other people's code.
◆ Current state
Mailu is a self-hosted mail suite shipped as a Docker compose stack, and the 2024.06.x branch shown here is its maintenance line. Every release in the window is a single-issue patch — a Roundcube bump, a CVE fix, an autoconfig tweak. The cadence looks high at ten pinned releases in five months, but each carries one change.
◆ Where it's heading
Most of what Mailu ships is downstream maintenance of its bundled components, Roundcube above all, which drove three of these ten releases. The project's own work here is defensive: escaping user-controlled fields in generated sieve scripts, setting X-Forwarded-By, adapting to Microsoft's new autodiscover. This is a product in steady-state operation, where the release notes track what upstream broke rather than what Mailu decided to build.
◆ Prediction
The next pinned release will most likely be another Roundcube or Alpine bump, since component upgrades triggered half the releases here. These entries say nothing about what is happening on the main branch.
Friendica
0.0COMMS
Friendica keeps betting on being the fediverse node that speaks everyone else's protocols.
◆ Current state
Friendica is a self-hosted decentralised social platform, released on calendar versions two or three times a year with codenames and a consistent structure: a handful of highlights, a security-fix credit, and a pointer to the changelog. The recent run — 2023.12, 2024.03, 2024.08, 2024.12, 2026.01, 2026.05 — shows the cadence thinning, with a full year between 2024.12 and 2026.01. Nearly every release credits externally reported security issues, most recently from Doyensec working with Mastodon.
◆ Where it's heading
Two lines of work dominate. The first is connectors: an initial Bluesky bridge in 2023.05 made bi-directional by 2023.12, Tumblr support maintained throughout, and ATproto account integration plus Bridgy Fed support improved in 2026.05. The second is Channels — the user-defined algorithm for sorting the network stream — introduced in 2023.12 and given performance and sorting work in every release since. Running against both is a deliberate pruning of legacy: OStatus dropped in 2024.12 after the project measured how few servers still needed it, and the fancybox addon deprecated alongside it.
◆ Prediction
Expect the next release to continue the ATproto and Bridgy Fed integration work and further Channels performance tuning, with the accessibility review started in 2026.01 producing more fixes. Given the year-long gap before 2026.01, the cadence itself is the uncertain part.
