FollowCarry

A free, one-click migration assistant for Fediverse users losing their home instance — preserving their network graph and pointing followers to their new home so a community doesn't dissolve when one server shuts down.

Target user

Fediverse users displaced when their home instance closes or migrates

Features
  • One-click archive of your posts, media, and following/follower graph
  • Auto-announce to followers with a personal migration message
  • Server recommendation engine based on language, region, and vibe of your old home
  • Bulk unfollow/cleanup of inactive accounts after migration
Why now

With toot.community announcing a hard Oct 28 shutdown, several thousand users need to relocate, and Mastodon's built-in tool only moves followers — not posts, not media.

Signals · overall 5/10
Demand
5/10

Need is real but episodic and niche: toot.community had ~2,500 MAU / 31k accounts before being absorbed by mastodon.world, Mozilla.social had only 270 active users, and the source HN thread was modest at 22 points — Mastodon docs themselves note 'posts will not be moved, due to technical limitations.'Blog post for August 2024 (and July.. and June.. and... so on)Mozilla exits the fediverse and will shutter its Mastodon server in DecemberMoving or leaving accounts - Mastodon documentation

Whitespace
7/10

No production competitor exists: Mastodon's built-in tool explicitly moves followers only and is Mastodon-only; fedi-port (the most ambitious comparable) is pre-award with no code committed and is waiting on an NLnet grant; remaining options are manual wiki guides or per-software exports.GitHub - sattva2020/fedi-portMoving or leaving accounts - Mastodon documentation

Monetization
3/10

Stated as free for a niche episodic audience; comparable projects (fedi-port) rely on NLnet/NGI grants, and even established instances like toot.community rely on a 'Support us' Patreon page — direct willingness to pay for a migration utility specifically appears low.GitHub - sattva2020/fedi-porttoot.community hub

Longevity
5/10

Instance shutdowns and admin burnout are an ongoing pattern (Mozilla, toot.community, others), so the underlying trigger persists, but demand is bursty and could shrink if Mastodon's built-in migration is extended to cover posts/media.Mozilla exits the fediverse and will shutter its Mastodon server in DecemberMozilla leaves the Fediverse and closes its own Mastodon instance

Feasibility
5/10

Doable but non-trivial: requires handling ActivityPub Move/alsoKnownAs, downloading/re-uploading media, serializing post graphs, and writing per-platform adapters (Mastodon ↔ GoToSocial, etc.) — fedi-port's roadmap estimates ~7 months for a v1.GitHub - sattva2020/fedi-portMoving or leaving accounts - Mastodon documentation
