Captra

The AI-native TypeScript framework for capability-first applications. This umbrella package exposes Captra's typed runtime, agents, adaptive memory, tools, approvals, state, React bindings, server transport, PostgreSQL adapters, and OpenAI integration.

npm install captra zod

import { capability, capabilityViews, defineApp, createRuntime } from 'captra'
import { z } from 'zod'

const hello = capability({
  name: 'hello',
  description: 'Say hello',
  input: z.object({ name: z.string() }),
  output: z.object({ message: z.string() }),
  run: async ({ name }) => ({ message: `Hello, ${name}!` }),
  view: { name: 'HelloCard' },
})

const app = defineApp({ name: 'Hello AI', scopes: [], capabilities: [hello], surface: capabilityViews() })
const runtime = createRuntime(app)

Use explicit entry points for each environment: captra/client, captra/react, captra/server, captra/server/node, captra/state, captra/postgres, and captra/openai.
