OpenAPI to CLI and SDK Generator

Turn your OpenAPI spec into a CLI, SDK, and docs with auth, errors, and publishing included.

Give us your OpenAPI spec. We generate a production-ready CLI, type-safe SDKs, install flow, auth handling, structured errors, publishing setup, and full documentation so developers and AI agents can adopt your API faster.

Terminal

You give us your OpenAPI spec...

$ acmeinc users list --limit 10

✓ Fetching users from /api/v1/users

Found 10 users. Displaying results.

Agents can call your API too

$ acmeinc billing invoice --customer cust_12345

✓ Invoice INV-2026-0342 generated ($249.00)

Why Teams Buy This

A CLI page is really an API adoption page.

Teams search for an OpenAPI to CLI generator when reference docs are no longer enough. The need is usually broader: install flow, auth guidance, structured errors, SDKs, and documentation that stay in sync as the API evolves.

Installable workflows beat reference-only onboarding

Developers and agents both move faster when the first step is npm install, brew install, or a binary download instead of digging through reference pages alone.

Auth and errors need one source of truth

CLI commands, SDK methods, and docs examples should agree on auth, request shape, and error handling instead of teaching three slightly different workflows.

Publishing only matters if sync is automatic

The win is not launching a CLI once. The win is keeping the CLI, SDK, and docs aligned every time the OpenAPI spec changes.

How It Works

OpenAPI in. CLI + SDK + Docs out.

One spec is all we need. We handle the rest and keep it current forever.

You provide

• OpenAPI Spec (Swagger / OpenAPI 3.x)

We generate

• CLI (npm / brew)
• TypeScript SDK (Type-safe)
• Python SDK (pip install)
• Docs (FREE)

Share your spec

Send us your OpenAPI / Swagger file.

We build it all

CLI, SDK, and full docs generated.

We publish it

npm, PyPI, hosted docs. Ready to go.

Always in sync

API changes? We regenerate everything.

Supported Outputs

Everything that should ship from one OpenAPI input

From one OpenAPI spec to CLI, SDK, docs, auth guidance, publishing, and ongoing sync.

Production-ready CLI

A branded CLI that maps every API endpoint to a human-readable command. Install via npm, brew, or binary.

Type-safe SDK

A fully typed SDK (TypeScript/Python) with autocomplete, error handling, and auth built in.

Full documentation (free)

Reference docs, quickstart guides, and usage examples for every command and method. Included at no extra cost.

Auto-sync forever

When your API changes, we regenerate the CLI, SDK, and docs. Keeping it in sync costs the same as creating it.

Auth & error handling

OAuth, API keys, bearer tokens. We handle auth patterns, plus structured error output agents can parse.

Published & distributed

Your CLI is published to npm/PyPI, docs are hosted, and everything is ready for developers and agents to use.

Category Fit

Who this works for, what ships, and when it's worth doing

A real category page should answer whether this workflow matches your API motion before you ever book a call.

Use cases

• API companies that want faster self-serve onboarding for developers.
• B2B SaaS teams adding a terminal workflow for support, automation, or internal ops.
• Platform teams that need docs, SDKs, and CLI distribution to ship from one spec.

Supported outputs

• A branded CLI with install commands for npm, Homebrew, or binary downloads.
• A TypeScript or Python SDK with auth, errors, and method-level structure built in.
• Hosted docs, quickstarts, examples, and publishing setup that match the generated outputs.

When this is a fit

• Your API changes often and the docs, SDK, and CLI drift today.
• Buyers care about implementation speed, not just endpoint completeness.
• You want a programmatic onboarding surface for both humans and agents.

Simple Pricing

One price. CLI + SDK + Docs. Sync included.

No hidden fees. Docs are free. Keeping everything in sync costs the same as creating it.

Starter

$250/month

• Up to 50 endpoints
• Perfect for early-stage products with a focused API surface.

Growth

$500/month

• Up to 100 endpoints
• For products with a broader API that need comprehensive coverage.

The Difference

Without a CLI vs. With a CLI

See why adding a CLI and SDK transforms how developers and agents interact with your product.

Without CLI & SDK

• Agents can't use your product
• Read docs, find endpoints, write code
• Hours to days
• SDKs break, docs go stale
• You write and maintain it
• Same as everyone else

With CLI & SDK

• Instantly callable by any agent
• npm install → start building
• Minutes
• Auto-synced on every change
• Generated and kept current, free
• First-mover in the agentic era
