Eve Studio

Eve Studio is a native macOS app for operating Eve agents. It runs, chats with, builds, wires up, and deploys every Eve agent on your machine from one window, without a terminal.

If you already build with Eve, Studio is a faster loop: a chat console with session controls, an editor for every capability, the eve registry in a gallery, and one‑click deploys. If you're new to agents, Studio provisions everything for you: a Node 24 runtime, the framework, and your first agent, so you can start by clicking, not configuring.

What is Eve?

Eve is Vercel's open-source agent framework. Eve Studio is an independent open-source project by Kybernesis and is not an official Vercel product. Eve's core idea: an agent is a folder.

my-agent/
├── agent/
│   ├── instructions.md      # the system prompt
│   ├── agent.ts             # model + config
│   ├── tools/               # typed actions the agent can call
│   ├── skills/              # load-on-demand instructions

│   ├── channels/            # where the agent is surfaced (Slack, web, …)
│   ├── schedules/           # cron-driven jobs
│   ├── memory/              # long-term memory slots
│   └── extensions/          # mounted extension packages (Arcana, …)
└── evals/                   # scored test cases

Eve discovers everything from the filesystem: a tool at agent/tools/get_weather.ts is the tool get_weather. It gives your agent a durable runtime (checkpointed workflows, isolated sandboxes, model routing) and deploys as Vercel Functions. The framework docs live at eve.dev/docs and the official integrations at eve.dev/integrations; this site documents the Studio app and how it uses each Eve concept.

What Studio adds

  • Chat: talk to an agent's local dev server or its production deployment, with streamed tool calls, subagent delegations, and approvals, plus Cancel, Compact, Clear, and Reset session controls.
  • Capabilities: browse, create, open, edit, and delete tools, skills, subagents, and hooks. Enable Eve's experimental self-modification subagent in a click.
  • Integrations: install anything from the official eve registry with eve add, or use guided wizards for Slack, Discord, Telegram, Teams, Twilio, GitHub, Linear, and Buzz.
  • Memory: Eve's session memory, memory slots, and Kybernesis Arcana as an official eve extension for long-term memory.
  • Schedules and evals: inspect, create, and run each.
  • Deploy: link to Vercel, pull the AI Gateway token, and ship to production with eve deploy.
  • Zero setup: provisions its own Node 24 runtime, installs Eve on first use, and walks Vercel sign‑in. A first‑time user never opens a terminal.
