Bluesky proper does not have a universal edit button. SecretSkies gives you the most you can do right now: an edited version that compatible third-party ATProto apps, forked communities, or community clients can choose to show while Bsky proper keeps showing the original.
Bluesky edit button
If your audience is only using Bsky proper, they will see the original post. If your audience is using a compatible third-party app or a forked community, SecretSkies can work like an edit button for that community.
SecretSkies is not a universal Bluesky edit button. Bsky proper will still show the original. But if you are using a compatible third-party ATProto app, forked community, or community client, SecretSkies can let that community show the edited version.
You searched for a Bluesky edit button because you want to fix something you already posted. The honest answer is that Bluesky proper does not currently let you edit a post everywhere. SecretSkies gives you the strongest available workaround: it creates an edited version that can appear where compatible ATProto communities choose to read the updated record.
So the promise is simple. You cannot edit Bluesky everywhere. You can edit what some compatible communities see.
The honest answer for people searching for post editing.
What works, what does not, and where edits can appear.
Bsky proper versus compatible apps and community clients.
The shortest possible explanation without drowning in protocol language.
No. It is not official and it does not change what Bsky proper shows.
It updates the ATProto record underneath a post so compatible communities may show the edited version.
No. People on Bsky proper will still see the original. Compatible third-party apps or forked communities may show the edit.
Because some communities want control over the version they display instead of being locked to Bsky proper.
