Everything you need,
nothing you don't

Full-featured Claude access with privacy and security built in.

Web search & fetch

Claude Code's native web_search and web_fetch tools work out of the box. Most providers silently block them. We don't.

1M context window

Send up to 1 million tokens per request. No artificial cap.

Zero prompt logging

All requests processed in RAM. Nothing written to disk. Your prompts are never stored, shared, or used for training.

Rolling usage windows

No midnight resets. Usage rolls on 5h and 7d cycles. Predictable capacity, no surprise lockouts.

IP-bound keys

Keys automatically bind to your IP on first use. Stolen keys can't be used from unknown locations.

India-first pricing

Priced in INR. Pay via UPI, cards, or net banking. No forex fees, no international card required.

Tenant isolation

Zero data sharing between customers. Your keys, usage, and traffic are completely isolated.

Drop-in compatible

Works with Claude Code, OpenCode, curl, any SDK. Change two env vars and you're done.

Priority support

Paid plans get priority support via email. Enterprise gets a dedicated Telegram contact.

Trusted by developers

Used daily by solo devs and teams running Claude Code full-time.
