Can I vibe code Substack?
Publish a newsletter and get paid, with discovery built in.
The Substack editor and its send-to-subscribers loop are easy to clone; doing so would give you a newsletter tool and none of Substack. The product is the network: the app's recommendation engine, Notes, the discovery feed, and the reader habit that sends new paying subscribers to writers who bring an audience. That distribution — plus subscription-payment handling and deliverability — is why people choose Substack over self-hosting. You can rebuild the publishing; you cannot rebuild the network that finds readers, so it is a no.
Build a self-hosted paid newsletter (a Substack alternative — the publishing, not the network) for my own audience. Include a post editor, a public archive with per-post pages and RSS, an email send to subscribers via a transactional API (such as Resend or SES), and paid subscriptions using Stripe that gate premium posts to paying members. Add a subscriber dashboard and a member account page. Use Next.js App Router with auth and a hosted Postgres, deployable to Vercel. Be explicit in the README that Substack's real value is its discovery network and reader app, which this does not attempt, and that deliverability at scale requires a dedicated ESP with SPF, DKIM, and DMARC.
A self-hosted newsletter with paid subscriptions via Stripe and a web archive — publishing without the discovery network.
- The discovery engine — recommendations, Notes, and the reader app
- A built-in audience that surfaces you to new subscribers
- Subscription payments and payout handling wrapped up
- Deliverability maintained across a huge sending domain
- The credibility and reader habit of the Substack brand
Substack is free to use because the writer is not the customer of the fee — the cut it takes buys distribution. The recommendation network and reader app turn other writers' audiences into your subscribers, and that growth is the entire value. No self-hosted clone has a network, which is why serious newsletters stay.
A prompt is the first move, not the whole game. Course 01 teaches you to take a prompt like this one to a shipped, working app — reviewing, correcting, and steering the agent the whole way.
