R.O.T.I — The Discord Bot That Actually Ships

~8 min readby Chips
Built for speed, scale, and taste. No glitter, just results.

Overview

R.O.T.I is a modular Discord bot engineered for large communities. It handles profile customization, notifications, and AI utilities without melting your rate limits.

  • 60,000+ servers
  • 99.9% uptime
  • Node.js + Redis + MongoDB

The Problem

Most bots crumble under spikes, block the event loop with AI calls, or pretend caching is a personality trait. We shipped a different playbook.

Architecture

Gateway & Shards: isolate hotspots, predictable memory.

API Layer: thin controllers, strict input contracts.

Workers: BullMQ for heavy tasks (AI, media).

Data: Redis for hot paths; MongoDB for state & audit.

Features

  • Per-server Personality: avatars/bios that fit the guild vibe.
  • YouTube/Notifications: resilient polling, de-dup, retries.
  • AI Utilities: OpenAI/Vertex with guardrails and timeouts.
  • Moderation: sensible defaults, burst protection.

Performance & Reliability

  • P95 command latency: 145 ms
  • Error rate: 0.12%
  • Uptime (90d): 99.94%
  • Cache hit: 87%

Command UX

Privacy & Security

Minimal data, opt-out paths, short retention. Secrets rotated, least-privilege roles, audit logs for admin actions.

Roadmap

Next: Events v3, smarter rate governance.

Exploring: Realtime summaries, dashboard.

Won't do: Anything TOS-grey.
