About

Skymarshal

Read full description

Skymarshal is an independent cleanup utility for your account on Bluesky. Search every post, reply, repost, and like you've ever made, then tidy it in bulk, with the kind of confirmations a permanent deletion deserves. Not affiliated with, endorsed by, or sponsored by Bluesky Social PBC. Skymarshal is a third-party tool; all trademarks belong to their owners. Built for power users who've been around long enough that "delete one post at a time" stopped being acceptable. CONTENT MANAGEMENT - Search every post, reply, repost, and like you've ever made: keyword, content type, date range, engagement count, alt-text, presence of media. - Inline media thumbnails so you can remember exactly which post you're looking at before you act. - Swipe to delete one at a time, or Select All from a search result and delete a hundred at once. - Multiple confirmation steps. Permanent deletions deserve them. - Rate-limit aware: bulk deletes pause and retry instead of hammering the network and getting throttled. FOLLOWING CLEANUP - Pull the full list of accounts you follow and check each one against six automation signals: mass-following, no posts, missing profile bits, suspiciously round numbers, very-new accounts flooding follows, and bad ratios. - Flag inactive accounts (no posts in N days, configurable). - Flag unverified handles without treating them as deleted or automated. - Sort by follower ratio, account age, post frequency, mutuality, or influence tier (mega, macro, micro, nano). - Bulk unfollow with the same rate-limit safety net the bulk delete uses. DYNAMIC SEARCH - Filter to "with media" or "without media." - Search alt-text alongside post text; finds that capybara post even when you didn't write the word "capybara." - Combine date range + engagement bounds to surface "dead threads" (low engagement) or "old bangers" (high engagement, distant past). FIVE PRIVATE WIDGETS - Worth Joining surfaces rising posts from people who regularly engage with you, balancing that relationship with current post momentum. - Follow Snapshot shows follower, following, and inactive-account counts. - Your Top Post clearly shows engagement on one of your own posts. - Follower Trend keeps a simple recent-count sparkline on your Home Screen. - Join In puts one timely conversation on your Home or Lock Screen. - Widgets read a snapshot written by the app after a scan. The extension makes no network requests of its own and adds no new tracking. PRIVACY - Sign in with an app password, not your main password. Generate a disposable one in your account settings and revoke it whenever you like. - No usage analytics or tracking. No third-party SDKs of any kind. - No Skymarshal account and no server I host. The app talks directly to Bluesky's endpoints. It sends no usage data to me or any service I run. WHO IT'S FOR Power users with thousands of posts. Journalists. Public-facing accounts. Anyone who wants their archive on their terms. Light users will find it overkill. That's fine. Skymarshal is the second tool you reach for when the first one isn't enough. WHAT IT'S NOT Not a social client. You can't post from Skymarshal. Not a network-growth tool. Just careful, bulk cleanup of the archive you already made. Made by Luke Steuber.
