Seq

Seq 10.1.15571.0, released by Datalust Pty Ltd as the twenty-third iteration of the product, is a self-hosted server purpose-built for the search, analysis, and alerting of structured logs and distributed traces. Positioned in the log management and observability category, it treats log events as fully-structured JSON rather than raw text, enabling rapid, schema-aware queries without regex parsing. Development, DevOps, and site-reliability teams deploy Seq to centralize telemetry from .NET, Java, Node.js, Python, Ruby, Go, Docker containers, message queues, and other sources via HTTP, OpenTelemetry/OTLP, custom inputs, or the seqcli command-line client. Once ingested, data can be filtered, aggregated, and visualized in real time through a built-in query language that supports complex projections, time-series calculations, and parameterised dashboards; alerts can be raised when thresholds or patterns are detected, feeding into PagerDuty, Slack, or generic webhooks for incident response. Typical use cases include live troubleshooting of production faults, performance regression analysis, security audit trails, compliance retention, and capacity planning, all performed within the user’s own infrastructure to maintain data sovereignty. The server is available for Windows, Linux, and Docker, offers fine-grained role-based access, and retains historical events through built-in compression and optional archival storage. Seq is obtainable at no cost from get.nero.com, where downloads are delivered through trusted Windows package managers such as winget, always providing the newest release and allowing simultaneous batch installation alongside other applications.
