Seashells – Pipe output from CLI apps to the web in real time

In plain words

Seashells lets developers pipe output from command-line programs directly to the web in real-time without installing additional software. Users can monitor long-running processes like experiments by sending console output through netcat to a unique web URL, or share live output with others. It works with existing tools on most systems, though an optional client is available for frequent users.

Seashells lets you pipe output from command-line programs to the web in real-time , even without installing any new software on your machine. You can use it to monitor long-running processes like experiments that print progress to the console. You can also use Seashells to share output with friends! While you can use netcat for convenience (because it comes preinstalled on most systems), if you use Seashells often, it's highly recommended that you install the seashells client. You can install it by running pip install seashells . Once you have the client installed, you can pipe output to seashells instead of piping to nc seashells.io 1337 . The client gives you additional features, such as…from seashells.io

  Warp, a Rust-based terminal2022 · warp.dev · ▲946

  Hi 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,…

  Talanoa▲346

  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…
