LogdyReal-time logs browsers and viewers
If you want to see the logs from an application in real-time, here is a list of a few tools that can be used
Logdy
Logdy is a versatile DevOps tool designed to enhance productivity in the terminal. Operating under the UNIX philosophy, Logdy is a single-binary tool that requires no installations, deployments, or compilations. It works locally, ensuring security, and can be seamlessly integrated into the PATH alongside other familiar commands like grep, awk, sed, and jq. It is particularly beneficial for professionals such as software engineers, game developers, site reliability engineers, sys admins, and data scientists who frequently work with terminal logs or outputs.
Logdy records the output of processes, whether from standard output or a file and directs it to a web UI. The web UI served on a specific port by Logdy, provides a reactive, low-latency application for browsing and searching through logs. It supports various use cases, such as tailing log files, integrating with applications (e.g., node.js, Python scripts, Go programs, or anything else that produces standard output), and tools like kubectl, docker logs etc.
One notable feature is its hackability with TypeScript, allowing users to filter, parse, and transform log messages by writing TypeScript code directly within the browser. This hackability provides flexibility to express custom logic without delving into the intricacies of other command-line tools. Overall, Logdy offers a convenient and efficient solution for managing and analyzing terminal logs.
