Build storefronts, embed checkout, and let agents transact on Cimplify. The SDK, hosted checkout, and UCP all share one backend and one data model.

Build with Cimplify

Whether you're shipping a full storefront, embedding checkout in an existing site, or building an agent that transacts on behalf of a customer, there's a path for it. Same backend, same data model, three surfaces.

Storefronts

A complete Next.js App Router storefront from six industry templates. 90+ React components and 13 typed services, so most of your code is brand.

Checkout

A single line of code on any site, embedded checkout, or full headless control. Mobile money, cards, 1-click via Cimplify Link.

Agents (UCP)

The Universal Commerce Protocol lets AI agents discover products, build carts, and check out, with signed mandates and verifiable consent.

Accelerate with the Cimplify CLI

curl -fsSL https://cimplify.io/install | sh   # one-time, ~5 seconds
cimplify init my-store --template retail       # scaffold a Next.js storefront
cd my-store && bun dev                         # mock API on :8787 + Next on :3000

A single native binary handles scaffolding, dev, env vars, deploys, custom domains, and self-update. The TL;DR page walks the ten commands from empty shell to live production domain; the full CLI reference covers every subcommand, JSON envelopes for agents and CI, and exit codes.

Reference

TypeScript SDK

createCimplifyClient + 13 services. Every method returns Result<T, CimplifyError>; never throws.

React SDK

90+ components, 30+ hooks. CimplifyProvider, CartDrawer, full-page CataloguePage and CheckoutPage.

Cimplify Link

Cross-merchant saved addresses, payment methods, orders, checkout acceleration, and customer account APIs.

REST API

Every endpoint the SDK uses, documented end-to-end. Flat /checkout, variant-aware /scheduling, signed UCP.

Tools

CLI

cimplify init / login / deploy / env / domains / update. Every flag, every JSON envelope, every exit code.

MCP server

api.cimplify.io/mcp exposes 26 typed tools so Claude / Cursor / ChatGPT can drive every workflow as tool calls.

Testing harness

In-process Hono mock + three pre-baked vitest suites. 30-second feedback loop, zero production calls.

Environments

Environment	Public key	Secret key	Description
Live	`cpk_live_`	`csk_live_`	Real data and real payments
Test	`cpk_test_`	`csk_test_`	Isolated sandbox, no real charges

Test mode uses a completely isolated sandbox business. Create your keys at app.cimplify.io/settings/developer.

For agents

This site is built for both human readers and AI agents.

Every doc URL has a Markdown twin: /llms/<path>.mdx, e.g. /docs/sdk/cart maps to /llms/docs/sdk/cart.mdx.
A section index lives at /llms.txt. Full content concatenated at /llms-full.txt.
Heading IDs are server-rendered, so anchor links work in raw HTML fetches.
robots.txt explicitly allows GPTBot, ClaudeBot, anthropic-ai, PerplexityBot, Google-Extended, CCBot.
Every scaffolded storefront ships /.well-known/ucp so UCP-aware agents can discover the business automatically.
