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.

andOTP features and specs

  • Open Source
    andOTP is open-source, meaning its code is publicly available for inspection, allowing users to verify its security and contribute to its development.
  • Offline Functionality
    It works offline, which adds an extra layer of security by not needing to connect to any network to retrieve codes.
  • User-Friendly Interface
    The application features a clean and intuitive interface, making it easy for users to set up and manage their two-factor authentication (2FA) accounts.
  • Backup and Restore Options
    It supports encrypted backups of the user's 2FA data, making it easy to restore credentials if you switch devices or reinstall the app.
  • Multiple Encryption Methods
    The app offers different methods of encryption to protect stored data, providing users with the option to choose the level of security that meets their needs.

Possible disadvantages of andOTP

  • Android Exclusive
    The app is available only for Android devices, limiting its usability for users on other platforms such as iOS.
  • Manual Data Entry
    Users need to manually enter or scan the QR codes for their accounts, which may be inconvenient for those who have a large number of 2FA accounts.
  • Maintenance and Updates
    As an open-source project, it may not receive regular updates and maintenance compared to commercial alternatives, potentially leading to security vulnerabilities over time.
  • Lack of Cloud Sync
    Unlike some other 2FA apps that offer cloud syncing to synchronize across devices, andOTP does not support this feature, requiring users to rely on manual backups.
  • Learning Curve
    Although user-friendly, those who are not familiar with setting up 2FA or using advanced features like encryption might face a learning curve.

Questions & Answers

As answered by people managing andOTP 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
