I was an SEO lead in enterprise. The dev team hated me. So I built an open-source landing builder to fix the gap
Hey,
I've spent years in SEO across different niches and enterprise teams. I've been on both sides — first as an SEO specialist, then as a full-stack developer.
And I kept seeing the same problem everywhere:
The SEO-Dev gap.
In every company I worked for, SEO tasks were stuck in a backlog. Changing an H1, adding a FAQ block, or updating a phone number — these are 2-minute tasks that took 2 weeks because they required a developer.
And I get it. Devs have real product features to ship. They don't want to be interrupted by marketing tickets.
The enterprise solution?
In big companies, we built internal landing constructors. Custom tools where SEOs could build pages themselves — no designers, no frontend devs, no waiting.
But here's the catch: every company rebuilds the same thing from scratch. It's expensive, time-consuming, and only big players can afford it.
So I built an open-source alternative.
SEO Landing Constructor — a free, self-hosted landing page builder with SEO at its core.
What it does:
- Blocks-based builder — Hero, Pricing, FAQ, Testimonials, CTA, Features. SEOs can assemble pages in minutes.
- Global shortcodes — change price, phone, or company name in ONE place. Updates across all pages instantly.
- SEO out of the box — SSR, metadata, sitemap, schema.org, Open Graph, optimized Core Web Vitals.
- Devs stay in control —
overrides/blocks/system lets you customize anything without touching core code. Keep your design system. - Self-hosted — deploy on your own domain, subdomain, or separate domain. No vendor lock-in.
- Bulk JSON import — migrate entire page structures or generate pages via AI in seconds.
What's coming (Roadmap):
- Live Preview & Draft mode — see changes before publishing (in progress)
- Advanced SEO blocks — Stats, Trust Bar, Comparison Table, Logos, Countdown, FAQ with schema
- Custom HTML Block — for full flexibility
- Built-in form handling — with server actions and validation
- Page templates — reusable structures to speed up creation
- A/B testing — for individual blocks
- Multi-language (i18n) support
- Reusable Widgets system
- AI-assisted content generation — for blocks
- Analytics integration — GTM/GA4 through server components
- CLI improvements — and template update mechanism
- Smart page templates — with block inheritance (edit template → updates all derived pages, except manual overrides)
Tech stack: Next.js 15 + Payload CMS 3 + Tailwind + shadcn/ui + PostgreSQL. MIT license.
⚠️ It's an MVP.
There are bugs. The UI isn't perfect. I'm not selling anything — it's completely free and open source.
I'm looking for:
- SEOs who want a tool they can actually own
- Devs who want to stop being interrupted
- Founders who want to let their marketing team move faster

I've seen this work in enterprise. Now I want to make it available for everyone — indie founders, small teams, and anyone who's tired of the SEO-Dev gap.
Try it. Break it. Tell me what's missing.
