JSON Utility is a free, browser-based toolkit for developers who work with JSON, YAML, and XML every day.

What it does

  • Validate & beautify JSON, YAML, and XML with clear, line-numbered error messages
  • Convert between JSON, YAML, XML, and JSON Schema
  • Diff two JSON, YAML, or XML files side-by-side
  • Query JSON with JSONPath expressions
  • Validate against a JSON Schema, including a batch mode for checking many files against one schema at once
  • Validate AI tool-calling schemas for OpenAI function calling and Anthropic tool use — checks structure, compiles the schema, and tests sample arguments against it

Why it's different

Everything runs entirely client-side in your browser — no file is ever uploaded to a server, and no account or signup is required. It's built to handle large files smoothly (virtualized editor, so even multi-megabyte JSON pastes stay responsive) rather than freezing like many browser-based tools do.

Who it's for

Backend and frontend developers, API integrators, and anyone building on top of LLM tool-calling APIs who needs a fast, privacy-respecting way to check their data or schemas without leaving the browser.

AWS Cloud9 features and specs

  • Integrated Development Environment
    AWS Cloud9 provides a set of tools for coding, running, and debugging applications, making the development process more efficient.
  • Collaboration
    Real-time collaboration features enable multiple developers to work on the same project simultaneously, making teamwork easier.
  • Preconfigured Workspaces
    Preconfigured environments speed up the setup process, allowing developers to start coding immediately without worrying about configuration.
  • Serverless Development
    Supports serverless apps and provides seamless integration with AWS Lambda, helping developers build modern applications.
  • Remote Development
    Enables development from any location without the need for a powerful local machine, as the IDE runs in the cloud.
  • Cost Management
    Cloud9 uses pay-as-you-go pricing, potentially reducing costs compared to maintaining and upgrading local development environments.

Possible disadvantages of AWS Cloud9

  • Internet Dependency
    Requires an internet connection to access, which can be a limitation in areas with unstable or no internet access.
  • Resource Limitations
    Dependent on the allocated AWS resources, which may require scaling and can incur additional costs for high usage.
  • Latency Issues
    Potential latency issues could affect productivity, particularly when used over slower internet connections.
  • Learning Curve
    Users unfamiliar with cloud-based IDEs or the AWS ecosystem may require time to learn how to effectively use Cloud9.
  • Vendor Lock-In
    Being tightly integrated with AWS services, it may contribute to vendor lock-in, making it harder to switch to other cloud providers.
  • Cost Management Complexity
    The pay-as-you-go model can lead to unexpected costs if resource usage is not closely monitored and managed.

JSON Utility features and specs

  • AI Tool-Calling Schema Validator
    Validate OpenAI function-calling and Anthropic tool-use schemas — checks structure, compiles the schema, and tests sample arguments against it.
  • Format Conversion
    Convert data between JSON, YAML, XML, and JSON Schema in one click.
  • JSON, YAML & XML Validation
    Validate and beautify JSON, YAML, and XML with clear, line-numbered error messages.
  • JSONPath Queries
    Run JSONPath expressions against JSON data to extract or filter values.
  • JSON Schema Validation
    Validate JSON documents against a JSON Schema, including a batch mode for checking many files against one schema at once
  • Batch JSON Validation
    Validate many JSON files against one schema at once — drag in a folder of files and instantly see which pass, which fail, and why.
  • 100% Client-Side / No Upload
    Every tool runs entirely in your browser — no file is ever sent to a server, no account required.

Analysis of AWS Cloud9

Overall verdict

  • AWS Cloud9 is generally considered a good option for developers, especially those working within the AWS ecosystem. Its cloud-based nature allows for easy access from anywhere, and the environment simplifies the process of scaling applications. However, for developers not working with AWS services, or those who prefer offline development, it might not be the ideal choice.

Why this product is good

  • AWS Cloud9 is a cloud-based integrated development environment (IDE) that is particularly beneficial for developers who need a robust and flexible environment. It offers seamless integration with AWS services, making it easier to develop, test, and deploy applications in the cloud. Cloud9 supports a wide array of programming languages, provides tools for real-time collaboration, and includes features like code hinting, debugging, and the ability to work on serverless applications.

Recommended for

  • Developers who frequently use AWS services
  • Teams that require real-time collaboration on code
  • Developers who need a browser-based IDE
  • Those looking to leverage the power of serverless computing within AWS

Questions & Answers

As answered by people managing AWS Cloud9 and JSON Utility.

What makes your product unique?

JSON Utility's answer:

  • Runs entirely in the browser — no file is ever uploaded to a server
  • No account or signup required, unlike many competing JSON tools
  • Includes a batch schema validator for checking many files against one schema at once
  • Includes a dedicated AI tool-calling schema validator for OpenAI function calling and Anthropic tool use — a feature few if any JSON tools offer

Why should a person choose your product over its competitors?

JSON Utility's answer:

  • Free, with no signup and no data ever leaving your browser
  • Covers more ground than most single-purpose JSON tools: validation, conversion, diffing, JSONPath queries, JSON Schema validation, and AI tool-calling schema validation — all in one place
  • Built to stay responsive even on large, multi-megabyte files, where many browser-based tools freeze or crash

How would you describe the primary audience of your product?

JSON Utility's answer:

  • Backend and frontend developers working with JSON, YAML, and XML data day-to-day
  • API integrators and QA engineers who need to validate or diff data quickly
  • Developers building on LLM tool-calling APIs (OpenAI function calling, Anthropic tool use) who need to validate their schemas before deploying

What's the story behind your product?

JSON Utility's answer:

It started as a simple JSON validator/formatter and grew into a full toolkit as more everyday developer needs came up — conversion between formats, diffing, JSONPath querying, and schema validation.

The AI tool-calling schema validator was added as more developers began building agents and needed a fast, offline way to sanity-check tool definitions before wiring them into a live model.

Which are the primary technologies used for building your product?

JSON Utility's answer:

  • React, Vite, and React Router on the frontend
  • Ajv for JSON Schema compilation and validation
  • Fully static, server-side prerendered HTML per route, deployed on Vercel — no backend server, since every tool runs client-side

Who are some of the biggest customers of your product?

JSON Utility's answer:

JSON Utility is a free, anonymous tool with no signup — we don't track or identify specific customer organizations. It's used by individual developers and small teams across the industry.
