Theres several open source options you can use.

The highest github stars one is called `zed` another one i've heard about is `Cline`

theirs also a few that yc backed ones:

`Void`

`Continue`

`PearAI`

For what its worth the non yc ones have way more github stars but im sure the yc ones are good too. I think `Continue` is the biggest yc one.

Happy pi.dev user here, give it a try! I would say that's kind of the "vim experience" but for harnesses: has the minimum, if you want something more you extend it :)

At Poolside we have pool (https://github.com/poolsideai/pool), it runs in a terminal and you can use it with any Agent Client Protocol compatible agent (https://agentclientprotocol.com/get-started/agents).

Nvim + Claude code. Or zed. Honestly basically every ide is adding agent harness features as their primary focus right now. Just throw a rock and you’ll hit something that will work for you. You can even just use emacs and have ai build harness features for you.

Since you've asked, I am working on one but it is super early days so I am just posting it here for feedback.

The idea is to make it fully autonomous so it is not really something that is meant to be constantly prompted and it is unlikely to fit most workflows but the idea is to make something that fits the future - not the present.

I'm very curious what coding agent interfaces other HN users are using.

I run a bunch of Claude / Codex TUIs + vim in terminal tabs on i3 workspaces on Linux whch I know isn't the most common.

I've been pretty damn happy with codex and vscode.

Between the codex app, cli, and vscode extension there are options for most ways of working

If you're open to using remote Linux VM's and a web-based interface, I quite like exe.dev and Shelley.

I am seriously thinking about adapting Kate with a fully opensource ai harness. it should be good enough for mac and linux for most devs. it already supports lsp server & has a established plugin infra so it should not really be any blockers. anybody wanna collab?

this class of spyware pretending to be ide makes me sick.

Paseo with opencode backing.

pi is for real engineers
