X Communities Off-Platform Migration Toolkit and Member-List Exporter Before the May 30 Hard Sunset
X is killing Communities on May 30, 2026 with no archive, no post export, and no migration into anything bigger than a 350-member XChat group. Moderators of multi-thousand-member communities (long-form post feeds, not just chats) are about to lose their member roster, their entire post history, and their moderation context. The builder opportunity is a 21-day-window toolkit that scrapes the member list and pinned posts, then bootstraps a destination (Discourse, Lemmy, Telegram supergroup, Circle, or a WordPress BuddyPress install) with the members pre-invited.
The migration window IS the product. Don't try to build a generic community platform... sell a one-shot 'we get your X Community on a working Discourse instance by May 28th' service with a kill-switch refund if you miss the date. Charge per active member and offer a stripped free tier for communities under 200 so the toolkit becomes the de facto exporter.

Community admins have a 21-day clock and X is providing no archive. Migration destinations exist but the bridge between the two is missing.
