The hard parts, already built right
Auth, user management, encrypted file handling — the pieces everyone gets subtly wrong (especially AI tools). Start from primitives adapted from a real encrypted-messenger codebase instead of rebuilding them from scratch and hoping.
Book a free discovery callYou're probably here because
- You're about to build auth from scratch — or let an AI tool do it — for the third time.
- The security-critical pieces (login, sessions, file uploads) are exactly where a mistake hurts most.
- Every week spent reinventing primitives is a week not spent on your actual product.
What you get
- Authentication and device/session management — token-based, multi-device, without the half-baked JWT footguns. Extracted and hardened from a real platform.
- User and identity service — profiles, multi-device, and a relationship/permission model done with proven patterns (SpiceDB / Zanzibar).
- Encrypted file service — chunked AES-256-GCM uploads, virus scanning, and presigned access, not a naive public bucket.
- Clean service boundaries (DDD) so each primitive drops into your app without dragging the rest along.
- Integrated into your stack and documented — yours to own and inspect, not a black box.
You skip months of rebuilding the risky, boring foundations and start from primitives built to a real encrypted-messenger's standard.
Common questions
Are these off-the-shelf or custom?
They're services I've already built for a real encrypted-messenger project (Chatter), adapted to your stack — so you start from a working foundation instead of from scratch, without SaaS lock-in.
Which primitives are available?
Authentication and device/session management, user/identity with fine-grained permissions, and encrypted file handling today — the bounded contexts from a real DDD codebase, extractable as standalone services.
Why not just use Auth0 or Firebase?
You can — but you trade control, cost at scale, and lock-in. These primitives are yours: self-hosted, inspectable, and built to the standard of an encrypted messenger, not a generic SaaS.
