Stack

Built in Rust + Next. Audited end-to-end.

The full technology stack behind the engine, the data plane, and this site — and why each piece earns its place.

How a request flows

From DB to your phone in under 100ms.

The bot writes to Postgres + Redis. axum serves them over a typed protobuf WS-RPC plane — every operator number is decoded, contract- checked, and streamed live to the cockpit. No JSON blobs.

Why this stack

Rust for the bot

Deterministic memory, predictable latency, no GC pauses while a fill is in flight. Compile-time SQL via sqlx means a column rename can't ship a runtime bug.

Next.js for the surfaces

Marketing pages stay static + SEO-ready. The dashboard hydrates client-side with SWR polling. Same codebase, both audiences served.

Hetzner EU for the host

ARM64 CAX21 — €15/mo, 4 vCPU, 8 GB RAM, Frankfurt. GDPR-friendly. systemd --user units + ufw. No cloud bill mystery.
