OpSee vs Sight Machine

OpSee is an open, modular manufacturing execution and industrial data platform for factories, covering MES, OEE, historian, analytics and AI. Its data logging module connects to MQTT brokers, OPC-UA endpoints and industrial protocols, and is described as always free. The historian stores and retrieves time-series process data. Analytics includes trend charts, Pareto analysis, custom KPIs, interpolation, annotations and multi-axis support; OEE tools provide real-time gauges, production trends, downtime categories and loss analysis. MES covers production orders, operator screens, quality checks, traceability and material tracking. AI features include anomaly detection, predictive insights, root-cause assistance and plain-language questions about historical data. OpSee can run at the edge, on premises or in the cloud, with managed hosting options named for AWS, Azure and GCP. Edge deployment supports Docker Compose and lists a requirement of less than 8 GB RAM. Starter costs €59 a month per equipment and Pro costs €95 a month per equipment.

Sight Machine is an industrial AI platform that connects factory and business systems, organizes plant data, and helps manufacturing teams identify production improvements. It maps assets, material flows, lines, and process interactions into an operational digital twin, then turns signals into production events and KPIs. Its agents continuously investigate quality drift, downtime patterns, and yield gaps, proposing findings for operations experts to review. Connections can include plant controls, historians, MES, ERP systems, and document repositories without custom middleware. Enterprise integrations use API, SDK, or ODBC, and manufacturing intelligence can be published as an MCP server. FactoryTX can run locally with Docker Compose, on a managed appliance or virtual machine, or in Kubernetes. Users can view and interact with existing dashboards in a mobile browser. Sight Machine says deployment takes days. It runs on Android, iOS, web, API, and self-hosted platforms. Pricing is on request under a custom enterprise agreement scoped to specified manufacturing lines or plants.
