#What is Evex?

Evex is a community-driven agent registry for developers building AI applications with Eve, Vercel’s filesystem-first agent framework. Instead of distributing agents as opaque hosted services, Evex packages their complete configuration, instructions, tools, skills, dependencies, evals, and supporting files as source-owned resources. Developers can inspect an agent and install it directly into an Eve project using the shadcn CLI. Once installed, Evex is no longer required at runtime, making it particularly useful for teams that value auditable AI infrastructure, customization, version control, and ownership of agent behavior.

#Features ⚡

• Shadcn-Compatible Registry: Uses the shadcn registry format, bringing the familiar shadcn add workflow to reusable AI agents.

• One-Command Agent Installation: Add agents directly to an Eve project through the @evex registry namespace.

• Full Source Ownership: Agent source files are copied directly into your repository instead of remaining hidden behind an external service.

• Preview Before Install: Developers can inspect the files and implementation of an agent before adding it to their project.

• No Runtime Lock-In: Installed agents run from your own codebase and do not require Evex as a runtime dependency.

• Editable Agent Architecture: Modify instructions, tools, skills, model configuration, policies, and integrations after installation.

• Environment Templates: Agents requiring credentials can include .env.example files documenting the necessary environment variables.

• Included Evals: Agent packages can ship with evaluations alongside their source code.

• Public Agent Metadata: Registry entries expose information such as source files, dependencies, author identity, setup instructions, and update information.

• Community Publishing: Developers can submit their own Eve agents to the registry through a reviewed pull-request workflow.

• MCP Support: Evex documentation includes workflows for browsing and installing agents through the shadcn MCP server from tools such as Cursor, VS Code, and Claude Code.

#Pro and cons

Pro ✅:

• Familiar installation workflow for developers already using shadcn.

• Complete ownership and visibility of agent source code.

• No permanent dependency on a hosted Evex runtime.

• Easy to customize agents for project-specific requirements.

• Git-friendly architecture makes installed agents easy to review and version.

• Growing selection of practical AI agents.

• Strong fit for developers experimenting with Vercel Eve.

Cons ⚠️:

• Primarily useful for projects already adopting the relatively new Eve ecosystem.

• Developers remain responsible for configuring credentials and deploying installed agents.

• Community agents may require individual review before production use.

• The ecosystem is still comparatively small compared with established package registries.

• Some agents depend on external APIs or services that may introduce additional costs.

#Included Components/Templates

Evex provides complete AI agent packages rather than traditional UI components or templates. The current registry includes agents across development, marketing, research, operations, and data workflows.

• Code Reviewer agent

• Knowledge Base Gardener

• Eve Agent Builder

• Brand Visual Asset Generator

• OpenUI Assistant

• Branded SEO Page Builder

• X Draft Assistant

• X Hot Topic Digest

• Supabase Data Analyst

• Postgres Data Analyst

• Linear Operations Agent

• Agent instructions and configuration files

• Skills and tool implementations

• Evals

• README/setup documentation

• Environment variable templates where required

#Pricing 💸

Evex currently operates as a community agent registry rather than a traditional paid marketplace. Its documentation focuses on public source-owned agents and installation through the shadcn registry rather than paid Evex plans.

• Registry access: Free

• Agent source: Publicly inspectable

• Installation: Free through the shadcn CLI

• Hosted Evex runtime: Not required

• External APIs, models, databases, or services used by individual agents may have their own pricing.

#Integrations 🧰

• Vercel Eve

• shadcn CLI

• shadcn Registry

• GitHub

• MCP

• Cursor

• VS Code

• Claude Code

• Slack, depending on the installed agent

• GitHub Apps, depending on the installed agent

• Linear, depending on the installed agent

• Supabase

• PostgreSQL

• Other APIs and services defined by individual community agents

Evex acts primarily as the distribution layer, while Eve provides the underlying filesystem-first framework for agent configurations, instructions, tools, skills, channels, and schedules.
