I am the initiator of this project. It&#x27;s an honor for Pippo to be mentioned on ycombinator.<p>I see some debates related to &quot;micro&quot; definition. A while ago a friend of mine posted some comments on reddit justifying why Pippo is &quot;micro&quot;. If you are interested to find out the arguments please read <a href="https:&#x2F;&#x2F;www.reddit.com&#x2F;r&#x2F;java&#x2F;comments&#x2F;3x1wsm&#x2F;why_are_java_web_apps_so_much_bloated&#x2F;cy0xlki" rel="nofollow">https:&#x2F;&#x2F;www.reddit.com&#x2F;r&#x2F;java&#x2F;comments&#x2F;3x1wsm&#x2F;why_are_java_w...</a>.<p>When I published the first article about Pippo on Dzone(about one year ago), someone asked me &quot;what are the key differences&#x2F;advantages of Pippo compared to another Java micro framework Spark?&quot; You can see my answer in the comment section of the article  (<a href="https:&#x2F;&#x2F;dzone.com&#x2F;articles&#x2F;pippo-micro-java-web-framework" rel="nofollow">https:&#x2F;&#x2F;dzone.com&#x2F;articles&#x2F;pippo-micro-java-web-framework</a>)
Pippo is small, modular but it&#x27;s not a simple toy. You have a lot of features that are not available in other (Java) micro frameworks.<p>If you want more features (security, scheduler, rest doc, event bus, mailer, DI), try Fathom (<a href="http:&#x2F;&#x2F;fathom.gitblit.com" rel="nofollow">http:&#x2F;&#x2F;fathom.gitblit.com</a>).  Fathom is a Undertow+Guice+Guava+Config+Logback stack over Pippo.
For people that like the super declarative approach (via Java annotations) from Spring Boot, we will try to upstream the fathom-rest module (<a href="http:&#x2F;&#x2F;fathom.gitblit.com&#x2F;rest" rel="nofollow">http:&#x2F;&#x2F;fathom.gitblit.com&#x2F;rest</a>) in the pippo-controller module.<p>There are some new features&#x2F;modules that are not documented yet (for example PippoTest class from pippo-test module, ...) but Pippo demos (<a href="https:&#x2F;&#x2F;github.com&#x2F;decebals&#x2F;pippo-demo" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;decebals&#x2F;pippo-demo</a>) are great and you can learn incrementally many aspects of Pippo from these.<p>Have fun!
