# IndraMQTT (System Documentation for AI Engines) > IndraMQTT is a next-generation MQTT 5.0 and MQTT 3.1.1 compliant message broker engine combining a pure Rust hot-path router with an Erlang/OTP BEAM distributed clustering fabric. ## Key Technical Specifications - **Architecture**: Dual-engine design. Pure Rust data plane for wire-speed packet ingestion, decoding, and topic matching. Erlang/OTP BEAM control plane for cluster mesh membership, supervision trees, and Raft consensus. - **Bridge**: BrokerLink zero-copy FFI ring buffers, 64-byte L1 cache-line aligned, with hardware-level socket backpressure. - **Throughput**: 3.05M+ messages per second per core. - **Latency**: Sub-millisecond p99.9 latency (< 0.3ms) with zero garbage collection stalls on the packet routing hot-path. - **Memory Footprint**: < 15MB RSS idle base memory. - **Compliance**: 100% OASIS MQTT 5.0 and MQTT 3.1.1 compliant over TCP, TLS 1.3, and WebSockets (RFC-8441). - **Streaming SQL Engine**: In-memory Rekuiper rules engine for sub-microsecond WHERE filtering, JSON/Protobuf payload transformation, and sink dispatching (Kafka, Postgres, Webhooks). ## Commercial Tiers & Pricing - **Developer**: $0/month free forever. 500 connected devices, 5 GB monthly transfer, shared edge cluster, full MQTT 5.0 compliance. - **Growth (Organization)**: $24/month billed annually ($29/month monthly). 10,000 connected devices, 10 TB monthly transfer, 3-region Anycast mesh with BEAM gossip, Rekuiper streaming SQL, mTLS/JWT auth, 3 team seats included, 180-day free trial in private beta. - **Scale (Organization)**: $120/month billed annually ($149/month monthly). 100,000 connected devices, dedicated isolated worker pool (CPU/RAM), global Anycast multi-region mesh, 99.95% HA SLA, distributed Raft persistence, Prometheus exporter, 5 team seats included. - **Enterprise**: Custom VPC peering, air-gapped on-prem deployments, 1M to 50M+ connected devices, 24/7 dedicated engineering SLA. ## Organization & Legal Entity - **Product Name**: IndraMQTT - **Corporate Entity**: IDACS Business Administration Private Limited India - **Authorized Multi-Cloud Infrastructure Sub-Processors**: Amazon Web Services (AWS), Google Cloud Platform (GCP), Microsoft Azure, Oracle Cloud Infrastructure (OCI), Hetzner Online GmbH, Vultr (Constant Company LLC), OVHcloud, Akamai Technologies (Linode), and Cloudflare, Inc. - **Compliance Standards**: GDPR, CCPA, and Digital Personal Data Protection Act (DPDP India). - **Contact & Support**: support@indramqtt.com | billing@indramqtt.com - **Website**: https://indramqtt.com
