JWT Generator

JWT Generator brings together 6 capabilities, including multiple algorithms, standard claims, and custom claims, in a single browser-based workspace. No installs, no sign-ups, no data leaving your machine. Every operation runs locally, so your files stay private by default.

Rune built JWT Generator for anyone who values getting things done over navigating menus and settings. Set issuer (iss), subject (sub), audience (aud), and expiration time with intuitive form fields. It is the kind of tool you bookmark once and reach for whenever the need comes up.

Start by configure claims. Choose algorithm, enter secret key, set standard claims and add custom claims as needed. JWT Generator accepts input immediately. No loading screens or configuration dialogs stand between you and your result.

Once your input is ready, generate token. Click generate to create a signed JWT using HMAC with your selected algorithm. Results appear in real time, giving you immediate feedback before you commit to a final output.

Finally, copy & use. Copy the generated token and use it in your API authorization headers or testing. The entire process from start to finish typically takes under a minute for most inputs.

For the best experience, keep these points in mind: Use a strong, random secret key (at least 32 characters) for HS256 in production environments. Set short expiration times (15-60 minutes) for access tokens and longer for refresh tokens. Small adjustments like these can make a noticeable difference in your output quality.
