Index Checker

🗄️ Connected = every result is stored in a shared Cloudflare D1 database, synced across all your devices & browsers. Leave blank to work in this browser only (local mode).

⚡ Index checks run server-side via Serper.dev — the key is stored as a server secret, so there's nothing to enter here. Just connect the cloud database above, then load URLs and press Start checking.

⚡ Parallel checks: at a time — higher = faster (Serper rate-limits are retried automatically; 8 is a good default)

⏱ Delay between checks: seconds — optional throttle; leave 0 for full speed

💡 For very large lists, load a few hundred URLs (or one site) at a time — the browser checks them one-by-one, so smaller batches are easier to manage.
