Seedsy

Open-source SEO + GEO autopilot. Analyzes your site, writes and publishes an article a day, and tracks whether ChatGPT, Claude, Gemini and Perplexity recommend your brand.

Stack: Next.js 14 · Supabase (auth + Postgres + RLS) · OpenRouter (one key for all LLMs) · Stripe (cloud mode only)

What it does

• Analyze — crawls your site: niche, audience, brand voice, 20 target keywords, competitors, buyer questions
• Plan — 30-day calendar of formats LLMs cite: comparisons, statistics, how-tos, FAQs
• Write — daily article with named-source stats, FAQ block, internal links, Article JSON-LD
• Publish — WordPress, Webflow, Shopify, Ghost, webhook (→ Zapier/Make), or a built-in hosted blog with sitemap
• Measure — weekly share-of-voice across ChatGPT, Claude, Gemini, Perplexity
• Extras — one-click X/LinkedIn drafts per article, 5 languages, backlink exchange network (cloud)

Local development

Prereqs: Node 20+, a free Supabase project, an OpenRouter key.

git clone https://github.com/your-org/seedsy && cd seedsy
npm install
cp .env.example .env.local

1. Supabase — in your project's SQL Editor, run supabase/schema.sql, then supabase/schema-v2.sql. Under Authentication → Providers → Email, turn off "Confirm email" for local dev. Copy the URL, anon key and service_role key (Project Settings → API) into .env.local.
2. OpenRouter — put your key in OPENROUTER_API_KEY ($10 of credits goes far; each article ≈ $0.03–0.15).
3. Set CRON_SECRET to any random string. Leave the Stripe block empty — self-hosted mode (the default) never touches it.

npm run dev    # http://localhost:3000

Sign up → paste any public site URL → you should land on a project overview with keywords and a plan button in about a minute.

Deploy

Docker (self-host):

cp .env.example .env   # same values as above
docker compose up --build -d

Crons don't schedule themselves off-Vercel — see the comments in docker-compose.yml and the full guide in docs/07-self-hosting.md.

Vercel:

npx vercel && npx vercel --prod   # add the same env vars in Vercel

Schedule the crons with the free Cloudflare Worker in cron-worker/ (set APP_URL in its wrangler.toml, wrangler secret put CRON_SECRET, wrangler deploy). Set NEXT_PUBLIC_APP_URL to your production URL and add it in Supabase → Authentication → URL Configuration.

Self-hosted vs cloud

Everything ships in this repo. Cloud behavior is enabled by NEXT_PUBLIC_DEPLOYMENT_MODE=cloud (lib/mode.ts) — not hidden code.

Limitations & responsible use

• Google explicitly treats scaled content abuse and link exchanges as spam policy violations; sites doing this can be deranked. Keep humans reviewing drafts, keep the backlink exchange opt-in, keep volume sane.
• LLMs invent things. Verify statistics before publishing, and don't publish unreviewed AI content in health, finance, or legal niches.
• CMS credentials live in Postgres (integrations.config). Before serving third parties: rate limiting, encrypted credentials, legal review — see docs/06-going-to-production.md.
