Mattermost vs Tella
A side-by-side editorial comparison of Mattermost and Tella — release velocity, themes, recent moves, and the top alternatives to consider.
Mattermost vs Tella: 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 Tella?
Tella adds a Free plan, redesigns the editor, and broadens distribution into Intercom and beyond.
Tella is in a sustained editor-polish-plus-distribution cycle. The big change: a Free plan now sits alongside Pro, paired with an in-product AI support assistant. The editor was redesigned with a left-side toolbar, lighter UI, and a new transcript sidebar. New layouts (50/50 split) and finer camera-bubble positioning (3×3 grid plus three sizes across orientations) give creators more compositional control. Distribution widens with an Intercom Help Center integration and a refreshed tella.com.

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.
Tella
6.3COLLABMEETINGS
Tella adds a Free plan, redesigns the editor, and broadens distribution into Intercom and beyond.
◆ Current state
Tella is in a sustained editor-polish-plus-distribution cycle. The big change: a Free plan now sits alongside Pro, paired with an in-product AI support assistant. The editor was redesigned with a left-side toolbar, lighter UI, and a new transcript sidebar. New layouts (50/50 split) and finer camera-bubble positioning (3×3 grid plus three sizes across orientations) give creators more compositional control. Distribution widens with an Intercom Help Center integration and a refreshed tella.com.
◆ Where it's heading
The product is leaning into accessible-funnel-plus-creative-control: lower the barrier to start (Free plan), make the editor look modern and inviting, and embed videos where customers already are (Intercom). View notification controls and webhook events for viewer activity hint at an upcoming push toward integration-ready video analytics.
◆ Prediction
Expect more distribution surfaces (Slack, Notion-style embeds beyond Intercom) and AI features beyond the support assistant — likely auto-chapters, B-roll generation, or transcript-driven editing. The Free plan likely drives an experimentation phase before the next pricing/packaging tightening.
