What we build with Elixir
Online gaming and betting platforms
Real-time multiplayer game servers, live odds engines, bet processing with sub-millisecond latency, concurrent user management and regulatory compliance for gaming.
Real-time communication
Chat systems, live streaming infrastructure, push notification engines and WebSocket servers handling millions of persistent connections with Phoenix Channels.
FinTech transaction processing
High-throughput payment processors, real-time fraud detection pipelines, order matching engines and financial event sourcing with guaranteed message delivery.
IoT data ingestion
Sensor data aggregation from millions of devices, MQTT broker integration, real-time alerting and time-series data processing with Broadway pipelines.
Distributed systems
Multi-node clusters with automatic failover, distributed caching, CRDT-based state synchronization and split-brain resolution for globally distributed applications.
Event-driven microservices
Event sourcing with Commanded, CQRS patterns, saga orchestration and reliable message processing with backpressure using GenStage and Broadway.
Elixir vs Node.js vs Go for real-time systems
| Factor | Elixir/BEAM | Node.js / Go |
|---|---|---|
| Concurrency model | Millions of lightweight processes, preemptive scheduling | Node.js: single-threaded event loop. Go: goroutines |
| Fault tolerance | Built-in supervisors, self-healing processes | Node.js: process crash = restart. Go: manual recovery |
| Hot code upgrades | Deploy without disconnecting users | Node.js: rolling restart. Go: rolling restart |
| WebSocket scale | 2M+ connections per server (proven at WhatsApp) | Node.js: 100K-500K. Go: 500K-1M |
| Distributed clustering | Native node clustering, built into BEAM VM | Node.js: external tools. Go: external tools |
| Latency consistency | Predictable sub-ms due to preemptive scheduling | Node.js: event loop blocking. Go: GC pauses |
| Ecosystem size | Smaller (Hex), but battle-tested for its niche | Node.js: largest (npm). Go: growing (Go modules) |
Pharos Production recommends Elixir for real-time systems requiring persistent connections, fault tolerance and predictable latency at scale - gaming, chat, IoT and financial event processing. Node.js suits general-purpose APIs. Go suits CPU-bound microservices.
Limitations: Elixir has a smaller talent pool than Node.js or Python - hiring takes longer and rates are higher. The BEAM VM is not optimized for CPU-intensive computation (number crunching, ML inference). For standard CRUD APIs without real-time requirements, Elixir adds unnecessary complexity over Node.js or Go. Library ecosystem is smaller than npm or PyPI, so niche integrations may require writing custom bindings.

-
Elixir handles millions of concurrent connections with predictable latency thanks to BEAM’s preemptive scheduling. Node.js event loop can block under heavy compute.
For gaming, chat and financial systems, Elixir provides fault tolerance that Node.js cannot match.
-
The Elixir talent pool is smaller than Node.js or Python but highly skilled. Pharos Production has maintained an in-house Elixir team since 2017 with experience across gaming, FinTech and real-time platforms.
-
Yes. Elixir services communicate via REST, GraphQL, gRPC or message brokers (Kafka, RabbitMQ).
We commonly deploy Elixir as a real-time layer alongside Node.js or Python services in a microservices architecture.
-
Phoenix for web applications and APIs, LiveView for real-time UIs without JavaScript, Broadway for data processing pipelines, Commanded for event sourcing and Nx for machine learning.
-
Real-time back-end MVPs start from $30,000-$60,000 (8-14 weeks). Full gaming or financial platforms with clustering and fault tolerance range from $80,000 to $250,000+.
