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.
View on GitHub →Publishing
Anyone can publish skills, tools, and agents to the Hub. Create a SKILL.md or plexo.json manifest and publish via URL or API.
