Features

Everything you need, built in

SDK.dev is the typed toolkit for building AI apps, a tool-calling runtime and agent framework that installs in seconds and scales to production.

Typed tool-calling

Define tools once and get end-to-end type safety across every model call.

One-line install

Add SDK.dev to any project and have an agent running before your coffee is cold.

Model agnostic

Swap between providers and models with a single config change, no rewrites.

Composable agents

Build multi-step agents from reusable tools, memory, and control flow.

Built for scale

Streaming, retries, and observability are wired in so production just works.

Safe by default

Sandboxed tool execution and guardrails keep agent actions in bounds.

How it works

Up and running in three steps

01

Install the SDK

One command adds the runtime and CLI to your codebase.

02

Define your tools

Write typed functions and expose them to your agent with a decorator.

03

Deploy anywhere

Run on your own infra or the edge with zero config changes.
