Pbar.io – Distributed progress bars that work in terminals and browsers
I built pbar.io because I was tired of SSH'ing into servers to check if my data processing scripts were still running, or worse, having them finish/crash without knowing. It's a simple REST API that lets you create and update progress bars from anywhere. The same progress bar can be viewed as terminal output (with ANSI colors), in a browser, or consumed as JSON. I'm actually tracking this HN discussion with pbar. The progress bar increases with each comment - watch it live as we discuss! Web: https://pbar.io/Y8yg3BG Terminal: curl…
Pbar.io – Distributed progress bars that work in terminals and browsers launched on September 11, 2025 with 25 votes, #538 of 8,160 launches that month and more than 90% of that year's launches. The site was still online in September 2026, 1 year on.
In plain words
Pbar.io is a REST API that creates and monitors progress bars for long-running scripts and data processing tasks. Users can update progress bars from anywhere and view them in terminals with ANSI colors, in browsers, or as JSON data. It supports hierarchical progress bars that automatically aggregate child progress, includes a Python package compatible with tqdm, and provides QR codes for monitoring on mobile devices. The tool is designed for developers who need visibility into remote script execution without SSH access.

Talanoa▲346Hi 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…

I made a built-from scratch Wayland Compositor to display any GUI app* in the terminal! I think there is a lot of unexplored potential in custom Wayland compositors, a lot of really cool things you can embed existing applications into! So, I started with embedding apps into the terminal because that is the easiest input/output (output is just utf-8 and I use the great `chafa` library for that, and I just read from stdin for the input). If you have any other ideas for cool Wayland compositors, let me know. I purposedly wrote 80% the app in Typescript to appeal to the most developers and…

Years ago I stumbled across a basic version of this concept and it stuck with me. I knew if I was ever going to take on such a project, it would need to be flawless, but without coding experience it was just another idea that would never happen. By the end of 2024, as AI coding tools exploded everywhere, I finally had a way to make it real. I started from zero knowledge and spent months collaborating with AI agents as a learning experience. Every pixel and every function went through me. The AI translated what I asked for into code, but every decision was human. I didn't use existing OS…
