Java SaaS frameworks?

Hi @littlebuddha,
you can have a look at https://Bootify.io - an application generator for Spring Boot. It is more a generic application builder and less focused on typical SaaS features, but should save a lot of time nevertheless when modelling your backend. Frontend currently has only Thymeleaf options, but the REST APIs are working fine if you would like to add your custom React/Angular/Vue stack.
All the best, Thomas
PS - Thymeleaf + HTMX getting a lot of traction currently and you get a maintainable app without an SPA

Have a look at https://www.jhipster.tech/

Top SaaS frameworks you can go with:

Symfony
Docker
Angular
Laravel
Vue
Django

I myself chose Go for my startup, despite of having 20yrs of Java experice, and knowing Go only a little.

There were few good reasons for this:

• I simply got bored with Java. I have it in my full time job, I've been doing this for years. Sure the technology is still great, but I simply wanted to have some fun working on my project and learn something new
• Java, when compared to Go is terribly slow! It also takes insane amounts of memory. Simple web service in Go needs 5-10MB of RAM and it can handle thousands concurrent requests thanks to goroutines (lightweight threads). Same thing in Java requires GBs of RAM and pretty powerful machine. So, it's also about using a tool that fits for the project
• Go feels very lightweight and is fun to work with. Works great with VSCode, no need for complex and expensive IDE, projects build in seconds

Highly recommend!

I don't know about any Java SaaS boilerplates geared towards indie hackers, and that might be a product you could make in and of itself!

I'm an intermediate Java programmer (most of my experience is JavaScript or C#), but if I wanted to spin up a SaaS product very quickly with the JVM I would use:

• Springboot
• Lombok
• PostgreSQL
• Gradle
• Tomcat
• IntelliJ
• Templating library w/ htmx (or your favorite frontend technology)

One of the coolest things about the JVM though is there's a vast array of tools and languages like Kotlin, Groovy, JRuby, and many more, very mature and widely supported – great open source community as well.

Work with what you know, don't feel pressured to do Javascript, PHP, or Python backends unless you really want to learn that tech. I think your 20 years of Java experience is definitely the way to go instead of trying to learn hip, shiny new tools though.

The startup ecosystem has moved much faster and titled towards Javascript frameworks. Because its relatively easy to code in React/HTML and also build backend with NodeJs all with Javascript knowledge. That is why more people are moving towards these frameworks. This also led to more people building SaaS boilerplates around Javascript.

I have been working in Micro SaaS Ecosystem and here are a few that really picked up momentum.
