The extension ecosystem for AI workspaces

Plexo Hub is the public registry for everything that extends what Plexo can do. Think VS Code Marketplace or Docker Hub — but for AI workspace capabilities.

What you'll find here

Skills

Procedural knowledge modules the agent can invoke. Written as SKILL.md files with structured frontmatter.

Tools

Callable functions that give the agent new abilities. API integrations, data transforms, system actions.

Agents

Autonomous actors with their own planning loops. Delegate complex tasks to specialized sub-agents.

Channels

Messaging adapters that connect your workspace to Telegram, Slack, Discord, and more.

Open source

Plexo is open source under the AGPL-3.0 license. The Hub is part of the Plexo monorepo and can be self-hosted by anyone running their own instance.

Publishing
