24 alternatives to Gottp – A Postman/Insomnia-Like TUI API Client Built in Go
What it does: A Postman/Insomnia-like TUI for building, sending, and organizing HTTP/GraphQL/gRPC/WebSocket requests. Supports saved collections stored as YAML/JSON files, environment variables, auth presets, response diffing, and request history. Why it's needed: This is the single largest gap in the Go TUI ecosystem. The abandoned wuzz (10.5k stars) proved massive demand for terminal HTTP inspection, but it's been dead for years. Posting (Python, ~6k stars) and ATAC (Rust, ~2k stars) are thriving alternatives in other languages. The Go options — gostman and go-gurl…

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…

Hi everyone, I recently published a small open-source project. It’s a minimal network packet analyzer written in Go — designed more like a learning toy than a replacement for Wireshark. It currently supports parsing basic protocols like TLS, DNS, and HTTP, and includes a tiny fuzzing engine to test payload responses. You can inspect raw packet content directly from the terminal. The output is colored for readability, and the code structure is kept simple and clear. The entire program is very small — just about 400 lines of Go code. I know it’s not anywhere near Wireshark’s level, and I still…

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…

We built Gonzo to make log analysis faster and friendlier in the terminal. Think of it like k9s for logs — a TUI that can ingest JSON, text, or OpenTelemetry (OTLP) logs, highlight and boil up patterns, and even run AI models locally or via API to summarize logs. We’re still iterating, so ideas and contributions are welcome!

Hello everyone! I was poking around GoLang's HTTP/networking capabilities to see what things I could do. Turns out it is pretty easy to insert your own networking stack into HTTP clients and servers.

I wanted to build a persistent message queue based on SQLite, because that's what I'm using for my main state anyway. This gives me ACID across state and messaging, which is nice! I've been inspired by the terminology of AWS SQS for this, but it's obviously much simpler. Maybe you can use it too. :)

Hey folks! Shahar and Tal from Keep (https://www.keephq.dev) here! For the last few weeks we’ve been building Peeng and can now share our beta with you: https://www.peeng.sh. Peeng is the easiest and quickest “heartbeat” architecture we could think of. Just pick a subdomain (e.g. x.peeng.sh), configure an interval, an endpoint, and a payload, and hit that subdomain every <X (interval) seconds — If you won’t, Peeng will send an HTTP POST request to your configured endpoint. It’s Pingdom/Cronitor/heartbeat.sh free alternative (but the other way around and A LOT…

Hey guys and gals! I'm learning Go at the moment and LOVING it. I was hoping to get constructive feedback on a project I'm working on - goatee - which is a notification server that utilizes Redis pub/sub and WebSockets. It's fairly bare-bones at the moment but I'm hoping to add in a lot more features as time goes on such as queueing and WebSocket channel subscriptions (via Go Socketio possibly).

I’ve been working on gotui, a modern fork of the unmaintained termui, rebuilt on top of tcell for TrueColor, mouse support, and proper resize handling. It keeps the simple termui-style API, but adds a bunch of new widgets (charts, gauges, world map, etc.), nicer visuals (collapsed borders, rounded corners), and input components for building real dashboards and tools. Under the hood the renderer’s been reworked for much better performance, and I’d love feedback on what’s missing for you to use it in production.

I've been building go-tui (https://go-tui.dev), a terminal UI framework for Go inspired by the templ framework for the web (https://templ.guide/). The syntax should be familiar to templ users and is quite different from other terminal frameworks like bubbletea. Instead of imperative widget manipulation or bubbletea's elm architecture, you write HTML-like syntax and Tailwind-style classes that can intermingle with regular Go code in a new .gsx filetype. Then you compile these files to type-safe Go using `tui generate`. At runtime there's a flexbox layout engine based…
