Learning and careers decision
Kajabi
A competent developer can build a useful subset (courses + payments + landing pages + email automations) in about a week and maintain it cheaply, but replicating Kajabi’s full integrated feature set, audience/network, mobile app bundling, and enterprise polish is impractical to match without product‑grade engineering and scale.
Visit website↗Open-source builds that already do this
Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need — the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship.
What a replacement has to do
- Host course pages and landing pages; accept payments and manage customers; gate content by membership; send marketing/transactional emails and basic automations; provide admin UI to create/manage products.
What it still won’t have
- Integrated proprietary audience network and prebuilt marketplace reach (Amplify)
- Dedicated mobile app bundling and value (branded mobile app included in product)
- Deep, production-grade feature parity (funnels, upsells/downsells, advanced automations)
- Enterprise-grade reliability, support, and scaling handled by vendor
What remains hard
- Product polish and ongoing maintenance

Paying is—cheaper in year one.

What we assumed
The verdict above measures whether you could build it. This one is only about money.
Runnable build prompt
Build a minimal self‑hosted Kajabi‑like app using Next.js (React) + PostgreSQL + Tailwind; deploy to Vercel (or DigitalOcean App Platform). Implement: (1) page/landing template editor with a few block types (text, media, CTA); (2) user auth and membership gating (Clerk or NextAuth); (3) product model for courses/memberships and admin UI to create lessons and upload video/file assets (store assets in S3); (4) Stripe checkout and subscription handling with webhooks and order records; (5) email sending and simple automations (SendGrid or Postmark) for purchases and drip sequences; (6) basic analytics dashboard (revenue, contacts). Out of scope: built mobile app, multi-tenant enterprise scaling, in-platform marketplace, AI agents. Include error handling, webhook retries, tests for auth/payment flows, and deployment instructions (env, DB migrations, backups).

The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time — so the same evidence always produces the same number.
