Linen
Lightweight, Google-searchable open source Slack and Discord alternative designed for online communities.
Linen is an open source community chat platform that positions itself as a lightweight, SEO-friendly alternative to Slack and Discord. It is designed for communities that want their conversations indexed by search engines and discoverable by new members, while still offering a familiar chat experience.
Linen ships with channels, threads, direct messages, reactions, and integrations with GitHub, and renders every conversation on the public web as well-structured, indexable URLs. This makes it an attractive choice for open source projects, developer communities, and public product support forums.
The project is released under AGPL-3.0 and is built as a TypeScript application. It can be self-hosted via Docker, with optional paid cloud and enterprise plans for communities that prefer a managed service.
