What OneDev Developer Tools Suite does

OneDev Developer Tools Suite is a collection of 222 free, privacy-focused utilities for everyday engineering work, including JSON formatting, JWT decoding, hashing, QR code generation, unit conversion, and CSP header drafting. All tools execute entirely within the user's browser, ensuring that data never leaves the device and no accounts or tracking are required to access the core functionality. The suite is designed to enhance productivity while prioritizing privacy, offering a lightweight alternative to desktop CLI tools for quick, on-the-fly tasks.

Step by step

How to use the OneDev Tools OneDev Developer Tools Suite

  1. 1

    Select a tool from the category list or search the sidebar by name (e.g., slug generator, cron explainer, HMAC).

  2. 2

    Paste the relevant input into the browser-based interface (e.g., JSON text into the formatter, an access token into the JWT decoder, or a private key into the Base64 tool).

  3. 3

    Review the output displayed directly in the tab; the tool processes data locally and does not upload payloads to a remote server.

  4. 4

    Use category pages for guidance on when to apply each utility and which common mistakes to avoid before proceeding.

  5. 5

    For large files or air-gapped environments, prefer a local CLI, as browser tabs have memory limitations compared to command-line utilities.

Is it right for you

Best for

Developers and engineers who need quick, privacy-respecting utilities for formatting, decoding, hashing, and conversion tasks without creating accounts or uploading sensitive data to external servers.

Limitations

  • Browser memory constraints may limit processing of multi-hundred-megabyte files.
  • Encoding and hashing functions (e.g., Base64, JWT decode) are not a substitute for encryption or secure vaults.
  • Google Analytics is used to track page views for site analytics, which may be a consideration for highly privacy-sensitive users.
Questions

OneDev Developer Tools Suite FAQ

Do I need to create an account or install software to use OneDev Tools?
No accounts or installations are required; all 222 tools run directly in your browser at onedev.tools.
Is my data sent to OneDev's servers when I use a tool?
No, every tool runs as JavaScript in your browser; input stays on your device and is not uploaded to a processing API.
Can I use OneDev Tools for encoding sensitive passwords or private keys?
Do not treat encoding functions like Base64 or JWT decode as encryption; they are not a vault and should not be used for production secrets.
What should I do if I need to process very large files?
For multi-hundred-megabyte files or air-gapped environments, prefer a local CLI tool, as browser tabs have memory limitations before a command-line utility does.
