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, or full control with Elements. 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 cards, addresses, orders. Four embeddable iframe Elements at link.cimplify.io.

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	`pk_live_`	`sk_live_`	Real data and real payments
Test	`pk_test_`	`sk_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.
