HedgeDoc vs Mattermost: at a glance
What is HedgeDoc?
HedgeDoc 1.x releases are now mostly advisories — security in, features rarely.
The 1.x line ships on a roughly six-to-eight-week rhythm, and almost every release leads with security fixes: HTML injection through an email localpart, YAML frontmatter denial-of-service, CSRF in the Gist export, a rate-limit bypass via the CF-Connecting-IP header, SVG upload script execution. Around that, the recent additions are operator controls — an external-link warning page with a whitelist, configurable login and signup rate limits, an option to restrict uploads to registered users or disable them entirely.
What is Mattermost?
Real product news arrives as v11.9 ABAC controls, buried under a run of security essays.
Mattermost's public feed is dominated by long-form security and zero-trust essays aimed at defense, government and regulated buyers. The one product release in the window, v11.9, pushes attribute-based access control down to the channel level and adds ranked attributes, program masking, and native Azure Blob Storage support. The company is selling governance posture as much as a chat client.

HedgeDoc
2.5COLLAB
HedgeDoc 1.x releases are now mostly advisories — security in, features rarely.
◆ Current state
The 1.x line ships on a roughly six-to-eight-week rhythm, and almost every release leads with security fixes: HTML injection through an email localpart, YAML frontmatter denial-of-service, CSRF in the Gist export, a rate-limit bypass via the CF-Connecting-IP header, SVG upload script execution. Around that, the recent additions are operator controls — an external-link warning page with a whitelist, configurable login and signup rate limits, an option to restrict uploads to registered users or disable them entirely.
◆ Where it's heading
This reads as a mature collaborative editor in hardening mode. New settings appear where an administrator needed a lever, not where a user asked for a feature, and the one substantial correctness fix in the window — data loss when five or more people edited a document at once — was a repair to the existing operational-transform client rather than new ground. Node 24 support and the removal of dead config options point the same direction: keeping a working product current.
◆ Prediction
Expect the next 1.x release to follow the same shape — one or more advisories plus a small configuration option — since every release in this window has done so.
Mattermost
5.0COLLAB
Real product news arrives as v11.9 ABAC controls, buried under a run of security essays.
◆ Current state
Mattermost's public feed is dominated by long-form security and zero-trust essays aimed at defense, government and regulated buyers. The one product release in the window, v11.9, pushes attribute-based access control down to the channel level and adds ranked attributes, program masking, and native Azure Blob Storage support. The company is selling governance posture as much as a chat client.
◆ Where it's heading
Access control is where the engineering is going: each recent release moves policy definition closer to the people running the mission rather than a central admin. The essay stream around it — zero-trust gaps after login, agentic AI in mission-critical operations, mobile data at scale — reads as demand generation for that same governance surface. Expect the product and the argument to keep converging on the claim that the collaboration layer is where zero-trust programs break.
◆ Prediction
The next release most likely extends ABAC further — policy inheritance, or attributes sourced from external identity systems — since v11.9 already handed channel owners the policy controls.
