SafeJSON is a browser-based JSON toolkit for developers who work with API responses, webhook payloads, JWTs, JSONPath queries, and JSON Schema validation.

It includes JSON formatting, validation, viewing, diffing, JWT decoding, JSONPath querying, and schema validation. Core JSON workflows are designed so pasted content is not intentionally uploaded, and users can verify the boundary in DevTools -> Network.

SafeJSON Pro adds advanced workflows for $5/month or $39/year.

Questions & Answers

As answered by people managing Prettier and SafeJSON.dev.

What makes your product unique?

SafeJSON.dev's answer:

Safejson runs all JSON processing 100% locally in the user's browser, never uploading any sensitive JSON payloads to external servers. Most competing JSON tools send your confidential data to their backends for parsing, while we guarantee end-to-end client-side privacy alongside a full suite of JSON utilities like diff comparison and JWT decoding.

Which are the primary technologies used for building your product?

SafeJSON.dev's answer:

Frontend built with vanilla JavaScript + modern browser native APIs for local file handling and parsing, lightweight CSS framework for responsive UI, Lemon Squeezy for subscription & license management, pure client-side JSON parsing libraries with no server-side data persistence.

Why should a person choose your product over its competitors?

SafeJSON.dev's answer:

Users handling API keys, production secrets or private business data avoid data leakage risks with our local-only processing. We offer the same rich feature set as mainstream JSON tools, but with stronger privacy protection, flexible affordable subscription plans, and device-bound license activation without forced account registration.

How would you describe the primary audience of your product?

SafeJSON.dev's answer:

Backend/frontend developers, DevOps engineers, cybersecurity professionals, and indie SaaS builders who regularly work with sensitive JSON data and prioritize data privacy, including enterprise developers dealing with confidential production payloads.

What's the story behind your product?

SafeJSON.dev's answer:

As a developer, I repeatedly faced anxiety when pasting sensitive API JSON into public online formatters, knowing the data could be logged or leaked on third-party servers. I built SafeJSON to fix this pain point: a fully client-side JSON toolkit that keeps all user data local, while packing all the everyday features developers need, and launched it as an indie MicroSaaS with fair pricing.

Who are some of the biggest customers of your product?

SafeJSON.dev's answer:

Individual freelance full-stack developers handling client confidential project data Small cybersecurity consultancies auditing API JSON payloads Indie SaaS engineering teams managing internal backend configurations DevOps specialists working with production environment JSON secrets

  • Readability in the age of AI-assisted programming
    Prettier - an opinionated code formatter for many languages, including TypeScript and JavaScript. - Source: dev.to / 8 days ago
  • Visual friction in development
    Line length, spacing, and indentation matter. My preference for code is roughly 80 to 110 characters. Longer lines become tiring to scan, while very short lines can create excessive wrapping. For formatting, tools like Prettier reduce debate and keep code visually consistent across contributors. - Source: dev.to / about 2 months ago
  • How to Build a Dependency Map of a Legacy Codebase Using AI Tools
    137Foundry provides legacy modernization services that include dependency mapping as a foundational assessment phase. Prettier and ESLint are useful companion tools for enforcing code style consistency as the refactoring proceeds. Node.js and Python.org official documentation are authoritative references for understanding the import and module systems of those runtimes. - Source: dev.to / 3 months ago
  • How to Prepare a Legacy Codebase for AI-Assisted Refactoring
    Prettier and ESLint are useful tools for establishing consistent code style as a baseline before starting structural refactoring - style differences in a diff make behavioral changes harder to spot. OWASP provides useful checklists for security-critical code review that apply directly to the critical path review step. - Source: dev.to / 3 months ago
  • How I Automated My Entire Claude Code Workflow with Hooks
    The matcher field takes a regex pattern. Edit|Write means this hook only fires when the Edit or Write tool is used. Claude running Bash, Read, or any other tool won't trigger it. The command itself uses jq to extract the file path from the tool input JSON, then pipes it to Prettier. Every file Claude touches gets formatted automatically. - Source: dev.to / 5 months ago
