Uptrace is an open-source observability platform that offers a comprehensive solution for monitoring, understanding, and optimizing complex distributed systems. Built on the OpenTelemetry API, Uptrace allows users to gain confidence in their production environments and deliver better code at a faster pace. With end-to-end tracing, users can track the progress of requests across different services and components, including timings, logs, and errors. Time series metrics enable efficient measurement, visualization, and monitoring of various operations using percentile, heatmap, and histogram analysis. The platform also features an intuitive query language for filtering, analyzing, and alerting against application data. Uptrace is cost-effective, capable of handling petabytes of data, delivering sub-second query response times, and requiring no maintenance. The platform's open-source nature, with over 25k stars on GitHub, reflects its commitment to building a reliable observability platform. Additionally, Uptrace offers an application overview dashboard to monitor the entire application stack, a data explorer with the power of SQL for deep insights, and time series metrics to supplement tracing. Users can dive into individual request performance, analyze errors and logs, compare performance trends, and leverage smart alerting to recover from incidents quickly. The platform supports multiple programming languages, including Go, Python, Ruby, Node.js, .NET, Java, Erlang, Elixir, Rust, and PHP. With Uptrace, users can identify and resolve issues faster, improve application performance, and recover from incidents before customers even notice.
