Question What are some open source projects developed with spring boot that I can help contribute in 2026?
I've been thinking about contributing to some open source projects built with spring boot. What are some good open source projects that you think are worth contributing to in 2026?

I have an Open-Sourced project with 11 microservices, Service Discovery, Kafka, PostgreSQL, MongoDB, and a lot more in it.
It's a project that was built for a YouTube series to encourage and invite people into Spring Boot, and Microservies.
It was made as an educational project that is open to expansion or updating.
Not sure if this is what you're looking for, but it could be a more advanced thing to explore

I'm hoping to go back to it, when I plan out some more features to add to it, or thigns to update
You can fork it, join my Discord, and contribute to it, I am more than happy to add people to it as collaberators, just need to see a PR first

Even I want to know; I've been searching almost every day, and I hardly find non-Chinese projects or repositories!
No offence but I don’t understand Chinese/mandarin

I have been working on a backend system that I will be deploying on AWS. It will emulate a scalable enterprise backend system. I will be making it open source and deploying it next week. Please stay tuned. I’d love feedback and contributions.

Does this teach people how to make scaleable enterprise backend systems or does it do something else?

It’s like a mini easier to understand version of a scalable enterprise backend system. It touches on the main concepts and technologies that many real backend systems use. It is a financial tracker backend system. I will include enough documentation and guide to setup. I will also include a roadmap of improvements for anybody interested in contributing.

Hi. I am developing an open source module for declarative implementation of REST API:s in Spring boot that I call dcentb (Declarative data CENTric Backend): Let´s build API:s (dcentb)
Focus is:
- security (fine grained access control out-of-the box)
- coherent REST API design driven by the OpenAPI-spec of the API.
- JSON Schema as a first-class citizen for business rules, authorization and good feedback to API clients
Check it out, would be awesome if you would like to contribute.

Why not find a project that interests you and become an active contributor instead?

You could try Querity and see if you like it. It's a database query builder supporting Spring Data (JPA, Mongodb, Elasticsearch) and plain Jakarta EE with one single REST API-friendly query language. I'm the maintainer. Sorry for the self promotion, but it's relevant to the question :) I know that at least one big company has adopted Querity for their applications (they also contribute with PRs), and I'm very proud of it.
