Username checker and ideas

Enter a username to check it against common handle rules: up to 30 characters, with only letters, numbers, periods and underscores. Enter your own words to get username ideas from fixed templates. The check runs in your browser and tells you which rule a name breaks, so you can fix it before you try to claim the handle.

Your name, brand or hobby, separated by spaces or commas.

    How it works

    1. 01

      The checker flags what would break the usual rules and adds advice for names that are legal but awkward, such as two periods in a row.

    2. 02

      Ideas combine your words with short prefixes, suffixes and separators. Every idea passes the same check, and the same words always give the same list.

    3. 03

      Copy a link to the result, or open it in the composer with 1Post and schedule it to every network.

    It runs in your browser. Nothing you type or choose is uploaded, and the page works without an account. To publish what you made, start a trial and open it in the composer.

    Questions

    What does it check?

    The shape of the name: length, allowed characters and awkward patterns such as two periods in a row. It also suggests alternatives to try.

    Why are ideas the same each time?

    They come from fixed templates and your words, so the same input gives the same list. Change a word to change the list.
