What is OpenGyver?
OpenGyver is an open-source, zero-dependency command-line interface (CLI) tool built in Go, offering a "swiss army knife" of over 47 commands and 180+ subcommands. It's designed for a wide range of common tasks including unit and currency conversions, various encoding and hashing operations, data generation (passwords, UUIDs, test data), and formatting/validation for different data types like JSON, HTML, and SQL. Its single-binary distribution makes it highly portable across Linux, macOS, and Windows.
This tool is ideal for developers, system administrators, and anyone who frequently performs data manipulation, conversion, or generation tasks. It can be used standalone for quick operations, integrated into CI/CD pipelines for automated processes, or hooked into shell scripts and AI agents (like Claude) to extend their capabilities. Its structured JSON output mode makes it particularly useful for scripting and piping results into other tools, enhancing automation workflows.
Key benefits include its extensive functionality, ease of installation and portability due to being a single binary, and its adaptability for both manual use and integration into automated systems. It streamlines many common development and data-related tasks, reducing the need for multiple specialized tools.

OpenGyver FAQ
How does OpenGyver achieve zero-dependency for its wide range of conversion tools?
OpenGyver is built in Go, which compiles into a single, self-contained binary. While it integrates with external tools like ffmpeg for audio/video conversions and Calibre for ebook conversions, the core OpenGyver CLI itself is distributed as a single executable without requiring additional runtime dependencies for its primary functions.
Can OpenGyver be used to automate tasks within a CI/CD pipeline, and how?
Yes, OpenGyver is specifically designed for this. Its CLI nature and support for structured JSON output make it ideal for scripting. You can integrate its commands directly into your CI/CD scripts to perform tasks like data validation, file format conversions, generating test data, or calculating file checksums as part of your automated build or deployment processes.
What kind of AI agent integrations does OpenGyver support, and what are the benefits?
OpenGyver can be hooked into AI agents, such as Claude, by adding its marketplace plugin. This allows AI agents to leverage OpenGyver's 16 native tools for tasks like encoding, hashing, conversion, generation, and even fetching real-time data like weather or stock prices, extending the AI's capabilities beyond its core language model.
Beyond basic unit conversions, what are some of the more advanced or niche conversion capabilities offered?
OpenGyver offers a wide array of advanced conversions including audio format conversion (33 formats), CAD file conversion (DWG, DXF, DWF), ebook conversion (25 formats), font format conversion (TTF, OTF, WOFF, etc.), image format conversion (RAW, SVG, WebP), presentation conversion (PPTX, KEY, ODP), and vector graphics conversion (SVG, EPS, AI, CDR, plus 20 more). It also includes tools to create GIFs from images and ICO files from images.
How does OpenGyver handle sensitive data like passwords or API keys during generation?
OpenGyver includes commands to generate secure passwords, passphrases, API keys, and secrets. As a CLI tool, these are typically generated locally on your machine. The output can be piped or redirected, allowing users to manage how these sensitive outputs are handled, such as storing them securely or using them directly in scripts, without them being transmitted externally by the tool itself.
