DEV
DEV username checker
Type a name to see if it's free on DEV. To check whole lists, or every short name at once, sign in and use the dashboard.
Free checks are limited to 5 every 10 minutes. Signed-in users get 100 free checks to start.
DEV name rules
| Length | 2 to 30 characters |
| Allowed | Letters, numbers and _ |
Names that break these rules are marked invalid and don't use a check.
Check thousands of DEV names
- Paste a list or pick one. Every 3 letter, 4 letter or easy to say name, or your own list.
- Pick DEV and any other sites. One run checks them all side by side.
- Get free names sent to your Discord. Each free name is marked with how rare it is.
Is a name marked open really free?
A name is only marked open when DEV itself confirms nobody has it. If the site doesn't answer clearly, we mark it unverified instead of guessing. Claim a free name quickly, before someone else does.
Do you register the name for me?
No. avaliuser tells you which names look free. You claim them yourself on DEV.
Is avaliuser part of DEV?
No. avaliuser is an independent tool and isn't made by or linked to DEV.
