    Milkman

    Milkman

    An extensible request/response workbench

    Milkman is heavily inspired by Postman. But I got sick of all those electron-based applications that need ages and loads of memory to start up. Therefore, this is a JavaFx-based workbench for crafting requests/responses. It is not limited to e.g. HTTP (or more specifically rest) requests. Due to nearly everything being a plugin, other things are possible, like database requests or GRPC, GraphQl, etc. Request-types (e.g. Http Request), request-aspects (e.g. Headers, Body, etc), editors for...

    Standalone Git GUI based on EGit

    Looking for a powerful, yet easy-to-use, fully open-source user interface for git? Well, there are plenty of options. One of our favorites is EGit. However, EGit is actually a plug-in for Eclipse rather than a standalone tool, such as GitKraken, etc. Nevertheless, even in projects where we actually use other editors or IDEs than Eclipse, we often found ourselves firing up an Eclipse IDE with EGit just to handle more complex git branch operations, for analysing the git history, and so on....

    Flogger

    Flogger

    A Fluent Logging API for Java

    Flogger is a structured logging API for Java that decouples how you log from where logs ultimately go, making it easy to change backends without rewriting application code. Instead of building messages eagerly, it uses lazy parameter evaluation so expensive string building only happens when a log statement is actually emitted. The API encourages structured key–value context and fine-grained rate limiting, which helps keep logs informative without flooding systems during high-traffic or error storms. ...
