Author here, thanks! The selling point is really compiled performance, no runtime, <50mb binary and self contained.

You can use the following to move to prev/next prompt: Alt+Shift+Up/Down or [u and ]u or you can customize it:

smelt.keymap.set("", "<C-Up>", function() return smelt.transcript.move_block("u", { forward = false }) end, { desc = "previous user message" })

smelt.keymap.set("", "<C-Down>", function() return smelt.transcript.move_block("u", { forward = true }) end, { desc = "next user message" })

Re:No existing dev tool fits perfectly, so I built my own on Sunday March 22, 2026 @07:11AM (#47476327)
Hey HN! I've been building custom dev tools with AI agents for the past year and finally wrote up the journey.

Would love to hear how others are approaching their workflows.

already done, this is what I use now: https://github.com/leonardcser/agent
Re:Claude Code but faster: a Rust implementation on Wednesday March 11, 2026 @12:05PM (#47337398)
Thanks for the feedback. The main performance focus was rendering.

Claude Code and other TUIs (except Codex) use a layer of abstraction over the raw terminal escape sequences.

I directly used `crossterm`, which gave me more control and lower latency.

For example if nothing is going on, I don't render anything in the terminal. Or only render at keypress.

Hello HN

Claude Code is great, but I find it a bit laggy sometimes. I built a local alternative that's significantly more responsive with local models. Just wanted to share :)

Hi, not that I know of. Most of the code would not change. It could easily be ported to different editors. The core is the go server (`server/`).
Hi, I tried the model and I am super impressed by the performance/quality. Thanks for making this open source!

I am the author of this Neovim plugin for edit completions. I was able to integrate it with the Sweep Edit model.
