eve

What is eve?

Vercel's open-source framework for durable backend agents.

Who is eve best for?

eve is best for TypeScript teams that want to build AI agents as a folder of files and run them in production.

• Long-running agents

  Each conversation is a checkpointed workflow, so a session can wait on people for days, survive a crash or deploy, and pick up where it stopped.

• Agents that run code

  Code the agent writes runs in its own sandbox, apart from your app: Vercel Sandbox when deployed, Docker or similar on your laptop.

• One agent in Slack and other chats

  Each channel is a small adapter file, with Slack, Discord, Teams, Telegram, GitHub and Linear included next to an HTTP API.

• Next.js teams on Vercel

  withEve() mounts the agent inside an existing Next.js app, and it ships like any other Vercel project, with a preview deployment per commit.

How much does eve cost?

eve is free and open source under the Apache 2.0 license; you pay only for the AI models it calls and for hosting, which on Vercel starts with the free Hobby plan or Pro at $20 a month.

eve has no paid tier of its own. At launch it deploys to Vercel, where running costs follow Vercel's pricing: Hobby is $0 a month and Pro is $20 a month with $20 of usage credit included. Sandboxes include 5 hours of active CPU a month on Hobby, and Pro bills from $0.128 an hour. The AI models an agent calls are billed separately, by their provider or through Vercel's AI Gateway. Full pricing on vercel.com. We checked these prices on 27 Sep 2026.
