Write once.
Deploy anywhere.

server/api/settings.get.tsDocs
import { defineEventHandler } from "h3"
import { kv } from "vite-hub/kv"

export default defineEventHandler(async () => {
  const [error, settings] = await kv.get("settings")
  if (error) throw error
  return settings
})

Define an Agent in one file.

An Agent is one more file in your server. It deploys with your app and uses the same storage as your routes.

server/agents/review.ts
import { defineAgent } from "vite-hub/agent"
import { browser, kv } from "vite-hub/agent/capabilities"
import { github } from "vite-hub/agent/channels"
export default defineAgent({
description: "Reviews pull requests.",
channels: {
channelsA pull request opens on GitHub. The run starts.
github: github({ pullRequest: { reconcile: { events: ["opened"] } } }),
},
driver: "codex",
driverCodex does the work. Claude Code and AI SDK also fit.
workspace: { mode: "write" },
workspaceThe repository stays on disk between runs.
capabilities: [browser(), kv({ mode: "write" })],
capabilitiesA browser, and write access to your app's KV.
})
server/api/reviews.get.ts
import { defineEventHandler } from "h3"
import { kv } from "vite-hub/kv"
export default defineEventHandler(async () => {
const [error, keys] = await kv.keys()
kvThe same store. No second database for the Agent.
if (error) throw error
return keys
})
