How Arcops Cloud Powers Paperplane

Explore Arcops Cloud platform

Arcops Cloud provides a complete full-stack backend (PostgreSQL, Redis, Mongo, S3 Buckets, Auth, and Frontend Deployment). Because Paperplane is 100% stateless, we only use two core primitives:

ArcAuth

Active in Paperplane

User management, authentication, and sub-millisecond API key validation.

FrontEdge

Active in Paperplane

Full-stack serverless deployment from frontend to edge APIs with zero DevOps cost ($0 infra).

Unused Arcops Cloud backend primitives: PostgreSQL (pgvector), Redis cache, MongoDB, and BuckStream S3 storage buckets — keeping Paperplane 100% stateless with zero database dependencies.

Frequently
asked
questions

Paperplane securely maps the generated OTP against the recipient's phone or email in memory. When your user enters their 6-digit code, you simply pass their number and code to /otp/verify. No user-managed tokens, zero Redis clusters, instant sub-millisecond response.
