Yapi – FOSS terminal API client for power users

I shared a previous version of yapi a few months ago in the comments section of a post talking about the insanity of Postman being 'down'. yapi has developed into a more mature project since then! https://github.com/jamierpond/yapi Still very early, but it makes me much more productive vs Postman, Bruno, Insomnia, etc. If youre a nvim/tmux culture human, you might like this!

In plain words

Yapi is an open-source terminal API client designed for developers who work in Neovim and tmux environments. It provides an alternative to graphical API testing tools like Postman and Insomnia, offering command-line functionality tailored for power users. Still in early development, Yapi aims to improve productivity for developers who prefer terminal-based workflows and are comfortable with keyboard-driven interfaces.

Yapi is an OSS command line tool that makes it easy to test APIs from your terminal. Yapi speaks HTTP, gRPC, TCP, GraphQL (and more coming soon). I use yapi daily in my development workflow. However, yapi is a SUPER young project and will have bugs, missing features and rough edges. If you download yapi , I would LOVE your feedback on how to make it better. Please open an issue if you have any suggestions or find any bugs! # create-issue.yapi.yml yapi: v1 # specify yapi version method: POST # or GET, PUT, DELETE, PATCH, etc. url: https://api.github.com/repos/jamierpond/yapi/issues headers: Accept: application/vnd.github+json Authorization: Bearer ${GITHUB_PAT} # supports environment…from yapi.run

    Hi HN! I just released version 1.0 of Posting, an open source terminal application I've been working on which you might find useful if you work with, test, or develop HTTP APIs! Posting (https://github.com/darrenburns/posting) is an HTTP client, not unlike Postman and Insomnia. However, as a TUI application, it works over SSH and enables efficient keyboard-centric workflows. Your requests are stored locally in simple readable YAML files, meaning they're easy to read and version control. Some other features include: - "Jump mode" navigation - Environments/variables…

    Hi HN! I'm Greg and I've been working on Yaak for just over a year. I usually describe it as a Postman alternative since most developers are familiar with that, but it's targeted more toward users that just want an API client (no mocking, testing, spec design, etc). Having also created Insomnia for a similar purpose, I never thought I'd build another API client again. But, after selling Insomnia in 2019 and watching it expand into the broader feature set of Postman, I was left wanting a simpler tool again. Yaak was my answer to that. It's hard to describe how it's better than the 100 other…

    I built PrettyMux as a native Linux terminal workspace for multitask workflows and keeping track of my agents. It’s a GTK4 app built on Ghostty/libghostty, with split panes, workspaces, vertical tabs, notifications, project-aware tabs (shows favicons/logo automatically), and an in-app browser so terminals and docs/tools can live side by side. I started it because I wanted something tmux-like for modern GUI workflows on Linux, but native and not Electron, there is cmux but only available on macos (prettymux compiles on windows and macos too but not tested for now there) It’s…

    Hey, HN! With all recent agentic workflows being primarily terminal- and tmux-based, I wanted to share a little project I created about decade ago. I've continued to use this as my primary terminal "window manager" and wanted to share in case others might find it useful. I would love to hear about other's terminal-based workflows and any other tools you may use with similar functionality.

    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…
