Websites and hosting decision
Unbounce
Build only if you don't need Unbounce's AI optimization and large-scale hosting; Unbounce's claimed advantage is AI and conversion data/models (proprietary) that are costly to reproduce, so continuing to pay is reasonable for equivalent functionality.

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
- Create, publish, and optimize campaign landing pages to capture leads and measure conversions.
What it still won’t have
- Smart Traffic AI optimization driven by Unbounce’s conversion models
- Built-in AI copywriting (Smart Copy) tied to Unbounce UI
- Large template library and brand-managed hosting/scale
- Concierge/professional services and enterprise traffic/limits
What remains hard
- Proprietary data
Leverage AI-driven insights powered by billions of conversions
- Proprietary models
Let AI and ML do the heavy lifting Simplify your CRO and provide visitors with a better experience by using our AI tools and insights powered by over two billion conversions.
- Brand trust
Over 15,000 brands rely on Unbounce to boost leads and sales while saving time and money.

Paying is—cheaper in year one.
On cash alone, building overtakes the subscription at 1 seat.

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 landing-page service using Next.js (React) + PostgreSQL + Vercel (or DigitalOcean) that supports: 1) a small set of editable landing-page templates (blocks-based editor, not full visual drag-drop), 2) publishing to a custom domain with CDN and SSL, 3) lead capture forms saved to Postgres and delivered via webhook/email, 4) simple A/B testing (traffic split, variant rendering, conversion counting, reporting dashboard). Out of scope: AI Smart Traffic, built-in AI copywriting, multi-tenant agency features, and concierge services. Include error handling, input validation, migrations, automated tests for publishing, form submission, and A/B routing, and documentation for deployment and recurring backup/maintenance tasks.

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.
