HOW TO PERSIST ADMIN SETTINGS ON A LIVE WEBSITE

Netlify / Vercel / GitHub Pages

With a static HTML file like this, admin changes are stored in localStorage — they live in your browser. This is great for a single admin using one device. To share settings across devices or browsers, add a one-line config sync:

// Add to admin export: copy this JSON to a file
const config = JSON.stringify(adminState)
// Place config.json in the same folder as index.html
// On load, fetch('/config.json').then(r=>r.json())
// .then(cfg => applyConfig(cfg))

✓ Free tier available · ✓ Auto-deploy from GitHub · Deploy time: ~30 seconds

Supabase (Free) + any host

Use Supabase (free PostgreSQL database with REST API) to store your admin config. Any browser, any device — always in sync.

// 1. Create table: admin_config (key TEXT, value JSONB)
// 2. On save:
fetch('https://your.supabase.co/rest/v1/admin_config', {
  method: 'POST', headers: { apikey: 'YOUR_KEY' },
  body: JSON.stringify({ key:'cs_state', value: state })
})
// 3. On load: fetch config and applyAllState()

✓ Free up to 500MB · ✓ Works with any host · ✓ Real-time sync across devices

Contentful / Sanity / Directus

Connect to a headless CMS. Each admin toggle maps to a CMS boolean field. Deploy a new static build when the config changes, or fetch at runtime via CDN.

✓ Team access with roles · ✓ Audit log · ✓ No code to deploy for content changes
