SubStack Migration Helper

One-click move from Substack to self-hosted platforms with compliance checks.

Problem

Substack's blanket compliance with Australia's Online Safety Act for all articles alienated some writers, who publicly announced they are leaving on Hacker News and lamented missing good blogs. Migrating to self-hosted Ghost, Write.as, etc., involves export, redirects, and subscriber transfer, which most authors can't handle alone.

Solution

A web tool that takes a Substack domain, auto-scrapes public posts, generates a static site or Ghost import package, and provides a compliance risk checklist per jurisdiction. It also helps migrate subscriber lists (CSV export/import) and guides custom domain redirect setup.

Users

Independent bloggers, journalists, and newsletter writers on Substack who are unhappy with platform policies and want content sovereignty.

MVP

Input Substack URL and scrape public posts; export as Markdown + image bundle; generate Ghost/Write.as/Hugo import files; produce compliance risk checklist; provide subscriber CSV migration guide.

Revenue

Per-export fee $5–$15, or $8/month subscription for ongoing sync and hosting options; affiliate revenue from self-hosting providers.

Why now

Content platform compliance pressure is rising globally, creator dissatisfaction with lock-in is growing, and self-hosting toolchains are mature enough for an indie developer to build a lightweight migration bridge.
