Flame vs Mattermost: at a glance
What is Flame?
Self-hosted dashboard that finished its feature arc and stopped shipping in 2023.
Flame is a self-hosted startpage for homelab services — app tiles, bookmarks, weather, and a search bar. The feature set it set out to build was finished across 2021 and 2022: custom app descriptions, Docker secrets support, a secondary search provider, and a custom theme editor. The most recent release in this feed is v2.3.1 from July 2023, and it is entirely bug fixes.
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.
Flame vs Mattermost: editorial side-by-side
Flame
0.0COLLAB
Self-hosted dashboard that finished its feature arc and stopped shipping in 2023.
◆ Current state
Flame is a self-hosted startpage for homelab services — app tiles, bookmarks, weather, and a search bar. The feature set it set out to build was finished across 2021 and 2022: custom app descriptions, Docker secrets support, a secondary search provider, and a custom theme editor. The most recent release in this feed is v2.3.1 from July 2023, and it is entirely bug fixes.
◆ Where it's heading
The arc reads as a project reaching completion rather than one under active development. Later releases shifted from adding capability to correcting the edges of what already existed — search-provider interactions, iOS input rendering, theme editor field sizes, label wording. There has been nothing since.
◆ Prediction
Nothing in these entries suggests further releases; anyone deploying Flame should treat the current version as the final one unless the project resumes.
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.
