The Agentic Backend

The backend built for AI agents
— and the humans who direct them.

The first backend-as-a-service where AI agents are first-class users. Data, auth, compute, hosting, and orchestration — all accessible via API, all operable by agents.

agent.ts
import { KapableClient } from "@kapable/sdk";

// 1. Agent connects to the workspace
const kapable = new KapableClient({
  apiKey: "sk_live_..."
});

// 2. Agent creates the data model
await kapable.data.create("customers", {
  name: "Acme Corp",
  plan: "enterprise"
});

// 3. Agent wires real-time updates
kapable.data.subscribe("customers", (event) => {
  console.log("Changed:", event.record);
});

// 4. Agent triggers an AI flow
await kapable.flows.run("onboard-customer", {
  customer_id: event.record.id
});
One API key. Agents handle the rest.

What no other backend can do.

AI agents aren't an add-on. They're built into the platform. Every API endpoint is designed for both human developers and autonomous agents.

AI Co-Builder

Describe what you want in plain language. Your AI assistant breaks it into tasks, generates schemas, wires endpoints, and tests the result.

co-builder.ts
// Tell the assistant what you need
await kapable.assistant.ask(
  "Create a customers table with name, email, and plan fields"
);
// ✓ Table created, endpoint live, types generated

Sandboxed Dev Environments

Give an AI agent a full development environment inside an isolated container. It writes code, runs tests, and deploys — without touching production.

sandbox.ts
// Spin up an isolated dev session
const session = await kapable.sessions.create({
  repo: "github.com/you/app",
  agent: "claude-sonnet"
});
// Agent codes, tests, and submits a PR

Visual Workflow Orchestration

Build multi-step AI workflows with a drag-and-drop editor. Budget caps, human-in-the-loop approvals, and 21 node types out of the box.

workflow.ts
// Define a workflow programmatically
await kapable.flows.create({
  name: "onboard-customer",
  steps: ["validate", "provision", "notify"],
  budget: "$0.50"
});

Universal AI Gateway

Route to any LLM through one API. One endpoint for every major model. Usage billing, token management, and automatic failover built in.

gateway.ts
// One API, any model
const reply = await kapable.ai.chat({
  model: "claude-sonnet",
  messages: [{ role: "user", content: prompt }]
});
// Switch models — same endpoint, same billing

Stop stitching. Start directing.

Building a modern application usually means signing up for five different services before you even write your core logic. You need Supabase for data, Auth0 for identity, Railway to host it, Resend for emails, and OpenAI plus LangChain to make it smart.

That's six dashboards, six billing accounts, and six APIs to glue together. With Kapable, agents handle the integration. You describe what you want — they build it on a platform designed for them.

One SDK. Everything included.

One dashboard, one API key, one predictable bill.

your-app.ts
import { KapableClient } from "@kapable/sdk";

const k = new KapableClient("sk_live_...");

await k.data.create("leads", payload);   // Database
await k.auth.signup(email, pass);       // Auth
await k.apps.deploy("prod");           // Hosting
await k.email.send(template);         // Email
await k.ai.chat({ model, messages }); // AI

Everything you'd expect, nothing you don't.

All the infrastructure a modern app needs — accessible to your code and your agents.

Dynamic Data API

POST your data, schema infers automatically. Real-time SSE on any table. PostgreSQL underneath.

Identity & Auth

Sessions, RBAC, JWT, OAuth providers, SSO. Built in, not bolted on.

Container Hosting

Deploy from Git. CI/CD pipelines, auto-TLS, isolated environments.

Serverless Functions

TypeScript to WASM. Fuel-metered execution. Data ABI for native DB access.

Transactional Email

Templates, delivery tracking, retry with backoff. Via API.

Webhooks & Scheduling

Event-driven hooks. Cron scheduling. Delivery history and retries.

GitHub Integration

Connect repos. Branch-based deploys. Webhook auto-deploy.

Feature Toggles

Boolean and percentage flags. Progressive rollouts. SDK included.

Secrets & Vault

Encrypted key-value store for API keys and credentials. Server-side encryption at rest. SDK and API access.

The vision

Today, agents build apps on Kapable with an API key and natural language. Tomorrow, anyone can describe an app in a sentence and have it running in minutes. We're building the platform where ideas become products — no assembly required.

Honest, transparent pricing.

Start for free. Scale predictably as you grow.

Pricing is subject to change before general availability.
