What it is AI-extracted, prompt v1, taxonomy v1, 2026-08-30, confidence not recorded

The former web frontend (React/TypeScript) of Mattermost, an open-source team messaging and collaboration platform. The repository has been archived and all development moved into the mattermost/mattermost monorepo.

Use cases

  • self-host a team chat alternative to Slack
  • customize the Mattermost web client UI
  • contribute to Mattermost frontend development
  • embed team messaging into an internal tool
  • audit the Mattermost web app source code
  • build plugins that extend the Mattermost web interface

When to choose

  • you want to modify or study the Mattermost web client for a legacy extended support release
  • you need a historical reference for code that predates the monorepo migration

When to avoid

  • you want to contribute code or use the latest Mattermost web app - use the mattermost/mattermost monorepo instead
  • you are starting a new chat product from scratch
  • you expect active maintenance or accepted pull requests here
