Seastar – Build and dependency manager for C/C++ with Cargo's features
Hi hackers! I'm a self-taught solo teenage dev working on Seastar, a unified build system and dependency manager for C and C++. It is capable of compiling and linking projects, managing recursive dependencies and headers, and even has a template system -- your C++ library is one `seastar new mylib --lang c++ --lib` away! Also, everything is configured in TOML, because TOML is awesome. C is one of my favorite languages, but I usually end up writing stuff in Rust because I love Cargo. Unlike C, Cargo handles the dependencies, linking, globbing, and so much more for you. So I wrote Seastar to…
Seastar – Build and dependency manager for C/C++ with Cargo's features launched on June 15, 2025 with 45 votes, #565 of 7,999 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
Seastar is a build system and dependency manager for C and C++ that simplifies project setup and management similar to Cargo for Rust. It compiles and links projects, manages recursive dependencies and headers, and includes templates for quickly scaffolding new libraries. Users configure everything in TOML files. The tool aims to bring Rust's convenient dependency handling and workflow automation to C and C++ development, with planned features including a package registry and CMake compatibility.

A simple, unified build system inspired by Cargo for C, C++, and maybe Rust - nonscalar/Seastar
This project is not yet a full build system! It is still in its infancy, and thus it is not recommended to use it for anything important! Seastar is a fast, extensible build system for C, C++, and maybe soon, Rust and Zig as well. I believe that it should be easy to make, prototype, and iterate upon designs. While C is still one of our most widely used languages, it makes it hard to create programs easily, especially for beginners. Instead, Seastar aims to be more like Rust's tooling with cargo , but supporting seamless compilation across more languages. Seastar is very simple to build and run. Assuming you have Cargo and Rust installed, clone the repository, cd into the example folder, and…from github.com

I built a Cargo-like build tool for C/C++Apr 2026 · github.com · ▲177I love C and C++, but setting up projects can sometimes be a pain. Every time I wanted to start something new I'd spend the first hour writing CMakeLists.txt, figuring out find_package, copying boilerplate from my last project, and googling why my library isn't linking. By the time the project was actually set up I'd lost all momentum. So, I built Craft - a lightweight build and workflow tool for C and C++. Instead of writing CMake, your project configuration goes in a simple craft.toml: [project] name = "my_app" version = "0.1.0" language = "c" c_standard = 99 [build] type = "executable"…
Warp, a Rust-based terminal2022 · warp.dev · ▲946Hi HN community, I’m Zach, founder and CEO of Warp, and am excited to show you Warp, a fast Rust-based terminal that’s easy to use and built for teams. As of today, Warp is in public beta and any Mac user can download it. It works with bash, zsh, and fish. The terminal’s teletype-like interface has made it hard for the CLI to thrive. After 20 years of programming, I still find it hard to copy a command’s output; I always forget how to use `tar`; and I always have to relearn how to move my cursor. To fix fundamental accessibility issues, I believe we need to start innovating on the terminal,…

Lstr – A modern, interactive tree command written in Rust2025 · github.com · ▲227Hi HN, (First time poster!) I'm the author of `lstr`. I've always loved the classic Linux `tree` command for its simplicity, but I often found myself wanting more modern features like interactivity and Git integration. So, I decided to build my own version in Rust with a philosophy of being fast, minimalist, and interactive. It was also an excuse to help learn more about Rust\! Here's a quick look at the interactive mode: https://raw.githubusercontent.com/bgreenwell/lstr/main/asset... I've just released v0.2.0 with some features I think this community might find…

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…

Hey HN! Pilots everywhere are required to keep a logbook of all their flying hours, aircraft, airports, and so on. Since I track everything digitally (some people still just use paper logbooks!), I put together some data visualizations and a few 3D globes to show my flying history. This globe is probably my favourite so far: https://jameshard.ing/pilot/globes/all If you’ve got ideas for other graphs or ways to show this kind of data, I’d love to hear them!

I was the main contributor to workout.lol, an open-source fitness app to easily build a workout routine. The project had traction (1.4k GitHub stars, 95 forks, ~20K visits/month), but was eventually sold due to video licensing hurdles. The new owner stopped maintaining it, and the repo went abandoned. Over the next 9 months, I sent 15 emails to try to save it : no replies. Feature requests & issues were ignored. The community was left with a "broken" tool let's say. I couldn't just let it die So I built the new version from scratch with the same open-source spirit, but a better…
