cURL to Ruby Converter

Transform shell cURL commands into production-ready Ruby code with support for standard Net::HTTP, Faraday, and HTTParty HTTP clients.

At a glance

cURL to Ruby Converter is a free online tool that converts cURL commands to Ruby code using Net::HTTP (standard library), Faraday, or HTTParty. It generates zero-dependency Ruby code with built-in URI parsing, SSL verification, and JSON payload handling. All processing is local: nothing is uploaded, and no account is required.

Standard Net::HTTP

Part of the Ruby Standard Library with zero third-party gem dependencies. Ideal for standalone scripts, lightweight utilities, and CI/CD automation without adding gems to your Gemfile.

Faraday Middleware

The gold standard HTTP client for production Rails applications. Features modular middleware for JSON serialization, automatic retries, connection pooling, and multi-adapter backends.

HTTParty Simplicity

Delivers clean, declarative one-liners for quick API calls with automatic response parsing and simple authentication options.

Why Use This cURL to Ruby Converter?

Standard Library Net::HTTP: Generates zero-dependency Ruby code with built-in URI parsing, SSL verification, and JSON payload handling.

Faraday Gem Support: Converts requests into modern Faraday middleware blocks with authorization, adapters, and custom headers.

HTTParty Simplicity: Generates clean, declarative HTTParty method calls ideal for quick scripts and API prototyping.

Multi-Line & Escaped Shell Support: Robust POSIX shell tokenizer supporting trailing backslashes, single/double quotes, and Windows caret continuations.

Full Authentication Extraction: Automatically maps Basic Auth (-u user:pass) and Bearer tokens (Authorization: Bearer) to native library methods.

100% In-Browser Privacy: All cURL parsing and code generation execute strictly in local browser memory. No headers, secrets, or URLs leave your machine.

How to Use cURL to Ruby Converter

Paste Your cURL Command

Paste your cURL command into the editor, drag-and-drop a command file, or select one of the built-in presets (GET, POST JSON, Basic Auth).

Select Target Ruby Client

Choose between Net::HTTP (Standard Library), Faraday (Gem), or HTTParty (Gem) based on your project requirements.

Copy or Download Ruby Code

Click "Copy Ruby Code" to paste into your codebase, or click "Download .rb" to save as an executable Ruby script.

Worked example: cURL to Ruby Converter

All cURL parsing and Ruby code generation execute 100% locally in your browser. No tokens, secrets, or request data are transmitted externally.

Frequently Asked Questions

Which Ruby HTTP client should I choose?

Net::HTTP is built into Ruby and requires zero gems, making it perfect for standalone scripts and minimal environments. Faraday is the industry standard for production Rails applications with its rich middleware ecosystem. HTTParty is ideal for fast, simple API integrations.

How does the converter handle JSON request bodies?

If your cURL command includes a valid JSON payload with -d, the engine formats it as a native Ruby Hash literal passed through JSON.dump, ensuring clean formatting and proper type handling.

Are my API keys and tokens kept safe?

Yes. All conversion logic runs 100% client-side in your local browser. Your cURL commands, credentials, and API endpoints are never sent to any server.

Does it support SSL/HTTPS endpoints?

Yes. For Net::HTTP, the generator automatically configures use_ssl: uri.scheme == https and handles default ports (443/80) appropriately.
