Javaflame – Simple Flamegraph for your Java application

Javaflame will generate a flamegraph of your application function calls, including the argument values and the return of each function. Check https://beothorn.github.io/javaflame to see an example. There are already some tools that render flamegraphs for java, but they are focused on measuring performance or require some other process running along with the application. They also record function calls, but do not record the arguments or return values from those functions. I needed instead something to help understand and debug my applications that was better than adding…

Javaflame – Simple Flamegraph for your Java application launched on November 7, 2023 with 31 votes, #1,209 of 4,333 launches that month and more than 75% of that year's launches. The site was still online in September 2026, 2 years on.

In plain words

Javaflame is a Java agent that generates flamegraphs showing function calls alongside their argument values and return results. Designed for developers who need to understand and debug applications, it creates interactive HTML visualizations without requiring separate processes or external dependencies. Unlike performance-focused flamegraph tools, Javaflame captures function parameters and returns by calling toString on each, offering an alternative to manual breakpoint debugging.

    Speeding up the code-test cycle for Java developers2023 · ▲69

    Hello HN, I am Parth. In my experience, the current form of testing automation takes too long. To solve this, I am creating a developer tool to speed up the code-test cycle for Java developers. It has two main parts: Direct Invoke - lets you call any Java function directly, without the need to execute the whole call hierarchy. (e.g. an HTTP endpoint) In my normal coding workflow, I use the “Evaluate Expression” feature inside IntelliJ IDE. I usually put a breakpoint somewhere in the code and after hitting the breakpoint by calling an HTTP api, let the execution remain paused while I explore…

    Videobug – The time travel debugger for JVM2022 · ▲63

    Hi All, this is Shardul here - I am the co-founder of Videobug. https://bug.video We are super excited to share Videobug with you. Videobug records run time code execution so that developers can watch it line by line as frequently as they want, right in their IDE. It takes away the pain of recreating exact conditions that led to a bug and saves developer time in every bug squash. Parth (my co-founder) and I have worked on multiple production grade applications in startups and enterprises. We used Logrocket, Sentry, and Datadog for logging and found ourselves adding more logs after…

    Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  • Hi HN, I’m Kashish, one of the co-founders of SpeedVitals, a platform for testing & monitoring website performance with a major emphasis on Core Web Vitals. Until now, our platform has only focused on Synthetic/Lab testing, such as Lighthouse tests and TTFB tests. But now, we have developed a Real-User Monitoring platform that doubles up as a Web Analytics tool. One major feature we have that most RUM tools lack is Performance Audits. Just like Lighthouse audits work on Lab test data, our audits work across all the real-user visits and gives suggestions on what task to prioritize first.…
