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.
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 });
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.
// 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.
// 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.
// 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.
// 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.
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.
