Validate a Fediverse or Bluesky handle
Check the handle format, open the right profile or lookup page, and choose whether to run a live account check.
Syntax checks stay local. A live check contacts the account server or Bluesky API only after you request it.
Who this is for
People checking a Fediverse or Bluesky identity before adding it to a launch or contact plan.
Inputs
- A Mastodon-style or Bluesky-style handle
- An explicit choice to run an optional live lookup
Outputs
- A normalized handle, syntax result, and likely profile link
- For a live check, the resolved account identity or a clear failure result
Limits
- A syntax result does not prove that an account exists.
- Live checks time out after eight seconds and can fail when a server blocks browser requests.
- The tool validates identities; it does not connect an account to OpenPost.
Privacy
Syntax checks stay local. A live check contacts the account server or Bluesky API only after you request it.
Next step
Copy the normalized handle or open the profile. Connect only your own publishing account from OpenPost Social accounts.
Check a social handle
Validate the format first. A live request only runs after you choose to check it.
Mastodon-style Fediverse handle
The syntax is valid. A live check can confirm that the server resolves it.

Result
Syntax checks run locally. Live checks contact the account server or Bluesky API.
