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.

What is Slack?

Slack raises the Marketplace bar back to ten installs while the agent platform consolidates.

Slack's developer platform runs two tracks. The agent build-out has produced a spark roughly every two weeks since June — MCP client, a skills plugin targeting Claude Code and Cursor, and Slack Code — and now has a consolidation date attached: assistant_view is deprecated in February 2027, replaced by an Agent Sessions API. The second track is platform administration and tooling, and this window belongs to it: Marketplace submissions again require at least ten installed active workspaces, held throughout the review, after a period at a lower temporary threshold. The CLI has shipped three times since late July.

Friendica vs Slack: editorial side-by-side

F0.0

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.

Slack raises the Marketplace bar back to ten installs while the agent platform consolidates.

◆ Current state

Slack's developer platform runs two tracks. The agent build-out has produced a spark roughly every two weeks since June — MCP client, a skills plugin targeting Claude Code and Cursor, and Slack Code — and now has a consolidation date attached: assistant_view is deprecated in February 2027, replaced by an Agent Sessions API. The second track is platform administration and tooling, and this window belongs to it: Marketplace submissions again require at least ten installed active workspaces, held throughout the review, after a period at a lower temporary threshold. The CLI has shipped three times since late July.

◆ Where it's heading

The install requirement moving back up is a distribution decision arriving in the middle of a platform push, and the two point the same way. Slack is making it easier to build agents and harder to list one, which favours developers who already have distribution — existing workspace tools and vendors — over a new app hoping the Marketplace supplies its first users. Combined with the assistant deprecation and the Agent Sessions API, the platform is narrowing on one agent surface and one class of builder rather than widening the funnel.

◆ Prediction

The threshold is described as a return from a temporary lower bar rather than a new policy, so the open question is what replaces the Marketplace as the discovery path for an app that cannot reach ten workspaces on its own. These entries do not answer it.
