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 adds device and channel attributes to its access policies.
Mattermost v12 has arrived in three parts: agents that act with the requesting user's access and leave audit trails, Cross Guard for managed transfers across security domains, and now policy attributes that describe the user, device and channel. Access rules can evaluate the situation of a request, not just the identity behind it. The audience is defense and regulated buyers.
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 adds device and channel attributes to its access policies.
◆ Current state
Mattermost v12 has arrived in three parts: agents that act with the requesting user's access and leave audit trails, Cross Guard for managed transfers across security domains, and now policy attributes that describe the user, device and channel. Access rules can evaluate the situation of a request, not just the identity behind it. The audience is defense and regulated buyers.
◆ Where it's heading
After five weeks of zero-trust and resilience essays, Mattermost is shipping the controls those essays described, one v12 component per post. Policy attributes tie the agent permissions and Cross Guard pieces into a single access model.
◆ Prediction
Expect further v12 component posts or a point release with configuration details; the entries so far are announcements with little technical depth, so the rollout schedule is unclear.
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.
