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 i created 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...

Hello Insomnia Users 👋. Recently, a way to import insomnia data was added due to the latest changes on insomnia. Rest assured that the restriction of having an account in Postman (and now, Insomnia) was one of the main reasons to create Milkman and such a thing will never ever happen.
The importer will be available in version 5.7.0 but is already implemented in the nightly release.

some resolved issues and FAQs are available in the wiki.

• Everything is a plugin: Request-types (e.g. Http Request), request-aspects (e.g. Headers, Body, etc), editors for request aspects (e.g. table-based editors for headers), importers, whatever it is, you can extend it. The core application only handles Workspaces with Environments, Collections, Requests and their aspects.
• Http Request Plugin: Several plugins are provided already that extend the core application to be a replacement for postman/insomnia. Crafting and Executing Http/Rest requests with json highlighting. Support Proxy-server configuration and SSE.
• Grpc Plugin: support of Grpc Services, Server Reflection and Streaming
• Test Runner: run several requests as separate test-scenario
• JavaFX Application: as in: fast (compared to electron at least :D) and skinn-able (you can extend milkman with your own themes using simple CSS).
• Commandline Interface: there is a command line interface for Milkman which allows to edit/execute requests on your command line.
• Slack Command: you can use /milkman <privatebin-url> in slack to share requests in a better way. More Info.
• Some more details of the core application features, such as hotkeys etc.

Note: see respective plugin folder for more details

The Http request plugin packaged with the release contains all means to do http request as well as import collections, environments or dumps from postman or insomnia. To migrate from postman, just export a dump-file from postman and import it by pasting its content into the Postman (v2.1) Dump-Importer.
To migrate from insomnia, see docs. The Http Request Plugin also comes with Proxy-support. Some proxies require credentials and support for supplying BASIC proxy credentials is built into the plugin. See Options-page to activate that as it is off by default. Additionally, the plugin supports chunked responses, enabling testing of Server-sent events (SSE).

No client fits all, so you are encouraged to write your own plugins to e.g. add headers that are necessary for your internal service structures or add importers for internal service registries.

A sample plugin was provided that extends all requests with a Note tab so you can add some description to any kind of requests.

More details about developing plugins can be found in the plugin development guide.
