Side-by-side code comparison of Hangfire (.NET) and JobRunr (Java) showing nearly identical APIs

Coming from .NET? Looking for Hangfire in Java?

Hangfire was a huge inspiration when creating JobRunr. Same API, same concepts. Fire-and-forget, delayed, recurring.

Stop Lying to Your Schedulers (Spring Boot 4) Part of the Stop Lying to your Stack series

"AI has made scaffolding infrastructure painfully easy. Add a library, copy the sample config, start the app. Problem solved.

Background processing is where that habit creates the most false confidence."

Great take by Simanta Sarma on implementing JobRunr in Spring Boot

Thanks for sharing our story how we've built ClawRunr (Aka Javaclaw)!

How We Built a Java AI Agent by Connecting the Dots the Ecosystem Already Had We built an AI agent runtime in pure Java using Spring AI, Spring Modulith, JobRunr, and Spring Events and called it ClawRunr (aka Javaclaw). Here's how the pieces fit together.

Building a Java AI agent doesn't mean starting from scratch. Nicholas D'hondt shows how to leverage existing ecosystem tools and connect them smartly.

#Java #AI #GenAI

Carbon Aware Processing The simple, open-source Java library for reliable background processing. Never lose a job again. Get a full dashboard, automatic retries, and durable job scheduling backed by your existing database.

Carbon Aware Job Processing now covers the US 🇺🇸

Add a time margin to your job schedule. JobRunr shifts execution to the lowest carbon intensity window.

Same job. Less CO2. One config change.

Reduce Your Java App's Carbon Footprint in 10 Minutes Your background jobs don't care when they run, but the planet does.

Software = 4% of global CO2. Most background jobs don't care when they run.

Shift them to when green energy is available. A few lines of code, zero infra changes 🌱

Balraj Adhana showed banks can modernize without risk:
Spring Boot + JobRunr -> 40% infra cost drop, 70% fewer manual reports, zero data loss. Automate EOM reporting & trade submits.

Observability: Tracing JobRunr Jobs Follow this guide to enable and configure distributed tracing for JobRunr Pro jobs using your observability platform of choice.

🔍 API call triggers a job. That job calls another service. Where did it fail?

You lose the trace at the queue. Your job becomes a black box.

Our new Pro guide shows how to fix this.
