Everything on your profile.
Four things that turn a claim into a credential.

Your discipline and rank, displayed clearly and ready to verify.
Competition record
Wins, losses, and draws, all in one place.
Academy verification
Your academy confirms your rank directly — no guesswork, no self-reporting.
QR code
A scannable link to your page, for your gym wall, your gi, or your card.

Your belt should carry your name.
A rank is only verified when the academy that awarded it says so. If you run a school, you are the only person who can confirm your students — and the only one whose word on it counts.
The first 30 academies get a founding rate held for life. Nothing is charged today, and there is no payment provider behind the form.
Free to create. More is coming.
There's no fee to build your profile, verify your rank, or share your page today.
A paid membership and a separate academy plan are in development — unlimited search and direct contact for members, roster management for academies. Planned at $9.99 a month for members and from $49 a month for academies, and neither is on sale yet.
Verified by your academy
Anyone can claim a rank online. On Onlyoss, your academy confirms it directly, so the badge on your profile means something a screenshot can't.
Your page lives at onlyoss.com/{username}, with a QR code you can put anywhere — your gym wall, your gi, your card.
One process, every profile.
Onlyoss confirms every verified rank through the athlete's own academy, and applies the same content guidelines to every profile.
The questions athletes actually ask.
- Who is this for?
- Martial artists who want proof of their rank beyond a claim on social media, and academies that want to manage and verify their roster.
- What does it cost to create a profile?
- Nothing right now. There is no fee to build your profile, add your competition record, or get your QR code.
- How does rank verification actually work?
- Your academy confirms your rank directly on Onlyoss. Anyone can say they hold a black belt online — a verified badge here means the school that ranked you backed it.
- Is there a paid plan?
- Not on sale yet. We are building a membership for unlimited search and direct contact, planned at $9.99 a month, and a separate plan for academies to manage and verify their roster, planned from $49 a month. Neither can be bought today — the Pricing page has the full terms.
- What happens if my academy is not verifying yet?
- Your profile still works — your rank and record show as entered. It just will not carry the verified badge until your academy confirms it.
- Can I update my profile later?
- Yes. Your rank, record, and academy can change whenever yours do — nothing here is locked in.
A rank is easy to claim.
Make yours provable — free, in a few minutes.
