Mattermost vs Miniflux: at a glance
What is Mattermost?
Mattermost v12.1 puts bots and burn-after-reading messages under the same access rules.
Mattermost v12 shipped in parts: agents limited to the requesting user's access, Cross Guard for transfers across security domains, and user, device and channel attributes in access policy. A November 9 partnership pairs v12 with Arqit's quantum-safe device trust. v12.1 on November 13 extends attribute-based access control to bot accounts and to Burn-on-Read permissions, and Desktop v6.4 fixes Boards on subpath deployments.
What is Miniflux?
Miniflux adds group-based admin roles and lets passkeys be the only login.
Miniflux 2.3.5 adds OpenID Connect admin role mapping from group claims, a force option on the feed refresh API and validation of CSS selectors in rewrite and scraper rules. Passkeys can now serve as the only login method when local authentication is disabled. The security list is long again, covering session sign-out on password change, feed cookie scoping and SSRF bypass blocks, following similar work in 2.3.4.

Mattermost
6.3COLLAB
Mattermost v12.1 puts bots and burn-after-reading messages under the same access rules.
◆ Current state
Mattermost v12 shipped in parts: agents limited to the requesting user's access, Cross Guard for transfers across security domains, and user, device and channel attributes in access policy. A November 9 partnership pairs v12 with Arqit's quantum-safe device trust. v12.1 on November 13 extends attribute-based access control to bot accounts and to Burn-on-Read permissions, and Desktop v6.4 fixes Boards on subpath deployments.
◆ Where it's heading
Each release closes another gap in one policy model for who and what can see a message: people, devices, channels, and now automation accounts and ephemeral messages. The audience stays defence and regulated buyers, and point releases are filling in v12 rather than starting new lines.
◆ Prediction
Further v12.x releases likely apply the same attribute rules to more objects, such as files, plugins or AI agent actions, following the pattern of v12.1.
Miniflux
5.0COLLAB
Miniflux adds group-based admin roles and lets passkeys be the only login.
◆ Current state
Miniflux 2.3.5 adds OpenID Connect admin role mapping from group claims, a force option on the feed refresh API and validation of CSS selectors in rewrite and scraper rules. Passkeys can now serve as the only login method when local authentication is disabled. The security list is long again, covering session sign-out on password change, feed cookie scoping and SSRF bypass blocks, following similar work in 2.3.4.
◆ Where it's heading
The two threads from earlier this year continue, but the security work has broadened from authentication strictness to the server's network and session behavior. SSO is the new thread: admin mapping and an authentication settings page make Miniflux easier to run for a group rather than one person. API additions and validation messages keep serving people driving it from other software.
◆ Prediction
The next release likely adds more identity options around OIDC and further SSRF hardening, since both have moved in consecutive releases. Neither is promised in these notes.
