Runs in your browser
When you paste JSON and click Format, the formatting happens right here in your browser. Nothing gets sent anywhere. We literally can't see what you type.
Just use it
Every tool works immediately. No account, no email, no "start your free trial." Sign up only if you want API access to use these tools in your scripts.
Works from your terminal too
All 17 tools have REST endpoints. Pipe a curl into your workflow and get JSON back. Free tier gives you 1,000 calls a day. See the API
DevDash is a free, browser-based suite of developer tools available at usedevdash.dev. It provides 17 utilities that developers use daily — including a JSON formatter, Base64 encoder, JWT decoder, regex tester, hash generator, and more. All tools process data client-side in the browser, meaning your code and data never leave your machine. No account or installation is required. DevDash also offers a REST API for integrating these tools into scripts, CI pipelines, and automated workflows.
Frequently Asked Questions
Is DevDash free to use?
Yes. All 17 browser-based tools are completely free with no usage limits and no sign-up required. The REST API also has a free tier with 1,000 requests per day. A Pro plan is available for teams that need higher API limits (10,000 requests/day) and multiple API keys.
Is my data safe with DevDash?
Yes. Every tool runs entirely in your browser using client-side JavaScript. When you paste JSON, encode Base64, or decode a JWT, the processing happens on your machine — no data is sent to any server. You can verify this by opening your browser's network inspector while using any tool.
Do I need to create an account?
No. All browser-based tools work immediately without any account. You only need to sign up if you want to use the REST API, which requires an API key for authentication. Creating an account is free and takes a few seconds.
What developer tools does DevDash offer?
DevDash offers 17 tools: JSON formatter and validator, Base64 encoder/decoder, JWT decoder, hash generator (MD5, SHA-1, SHA-256, SHA-512), UUID generator, URL encoder/decoder, regex tester, timestamp converter, password generator, SQL formatter, cron parser, Markdown preview, color converter, text diff, QR code generator, Lorem Ipsum generator, and an AI content detector.
Can I use DevDash tools from the command line?
Yes. All 17 tools are available as REST API endpoints that return JSON responses. You can pipe curl commands into your scripts, CI pipelines, or any HTTP client. See the API documentation for endpoints, parameters, and examples.
Do I need to install anything?
No. DevDash runs entirely in your web browser. There is nothing to install, no extensions to add, and no dependencies to manage. Just open usedevdash.dev and start using any tool immediately.
