How Pro reaches your server
Cerid runs on your hardware. Nothing here ever connects to your instance.
STEP 1
Check out here
Payment is handled on this site by Stripe. Your Cerid server never talks to a payment provider.
STEP 2
Get a license key
You receive a signed key immediately after checkout, and again in your receipt email.
STEP 3
Paste it into the app
Settings → Plan & Billing → Activate. Verified offline, so it works air-gapped. No reinstall.
Want to try before paying anything? Install Core and start a 14-day Pro trial in the app — no credit card, no account.

No cloud account needed. No API keys required to start (Ollama runs fully local). Add an OpenRouter key later for access to Claude, GPT, and other frontier models.
Bring Your Own Key
All tiers support your own OpenRouter API key. Use Claude, GPT, Gemini, Llama — or run Ollama locally for zero API costs. No vendor lock-in. Your key is Fernet-encrypted at rest.
