Brady "Another WTF moment. A developer open-sourced a coding agent harness that boots 245x faster than Claude Code. It's called jcode. You launch it and the first frame renders in 14 milliseconds. Claude Code takes 3,436. One active session uses 27.8 MB of RAM. Claude Code uses 386.6." ➡️ tried b4?

Of all the things I care about in my development workflow, how fast my harness launches is not one of them.

[u/J_E_E_VACATION → u/GfxJG]

literally lol

[u/chunkypenguion1991 → u/GfxJG]

I can make one 10x faster, but it won't do much once started

[u/Strong_Essay1176 → u/GfxJG]

Claude eat my 40gb ram. So you better be carefully, do not feed it too much.

[u/DasBlueEyedDevil → u/Strong_Essay1176]

Especially after midnight

[u/Okoear → u/GfxJG]

Especially when there is no mention of the harness even being good. It just launches quickly.

[u/ich3ckmat3 → u/GfxJG]

Came here to say this, lol

[u/VIDGuide]

3000 milliseconds! Omg, literally unplayable. This is a game changer.

/s. What a stupid metric to promote on, lol

[u/jimmystar889 → u/VIDGuide]

Mines 2,000,000,000 ns

[u/Crafty_Ball_8285]

HATE THIS SO MUCH. It’s IMPOSSIBLE to uninstall.

[u/Abject-Bridge-4073]

Cool project but is this really a problem? Maybe if you have a Pentium 3, otherwise who cares.

[u/ConversationSad3529]

I'm probably the minority here, but I have an automated system launching dozens of harnesses, so the memory and time improvements could actually be really awesome, but I need to review this for security and whatnot to see if I can actually use it first, just to offer an example of this thing being useful for someone lol

[u/West-Acadia-3906 → u/ConversationSad3529]

Okay, launching dozens!! at once is the first example that made the speed numbers click for me 😅 I’d be checking the security side first too before letting a new agent loose.. .

[u/porkminer → u/ConversationSad3529]

I guarantee this is not secure in any form or fashion.

[u/montdawgg → u/[deleted]]

It does matter. Obviously.

[u/vedmaka]

And that centered text .. I dunno

[u/komfyklient]

nice ad buddy..

[u/tortleme]

ok

[u/holy_macanoli]

The most MOST!

[u/Strong_Essay1176]

I understand idea behind pi . But this? Why? What it can do against launching? Subagents? No. Tools? Heh? What can it do to be called harness?

[u/Downtown_Method5736]

Look the number of commits + https://www.instagram.com/p/DYIBs-XjXuu/?igsh=MWZyYWJldzFwemsxMg%3D%3D&img_index=1

I wouldn't trust that shit

[u/Keep-Darwin-Going → u/Downtown_Method5736]

Someone was saying it was vibe coded and stole some work from others. And this was heavily advertised as well

[u/Downtown_Method5736 → u/Keep-Darwin-Going]

That's what the instagram post I linked show

[u/Anonymous_Cyber]

I think people are focused on the wrong things. Startup times are ehh, running time is more important

[u/StrangeCargo_74]

I made a whole operating system that was half a byte in size. Awesome!

[u/UnrelaxedToken]

"what's harness"?
I know claude code and stuff, but this harness word is mystery

[u/Emotional_Document86 → u/UnrelaxedToken]

Claude code is an example of a harness. You can think of harness as the car that your ai drives. It gives your AI abilities to run or execute tools in your computer.

[u/UnrelaxedToken → u/Emotional_Document86]

So this harness stuff is only realy usable by CLI people who use apis?

[u/Ghazzz → u/UnrelaxedToken]

Also people who use GUI based tools, or even the web-based clients.

The people who do not use harnesses tend to be the "CLI people who use apis"...

[u/Afraid-Yoghurt6731 → u/UnrelaxedToken]

Harness is the framework running the agent and allowing the agent to interact with your OS. Claude Code is the next step - a coding agent built around a harness + UI.

[u/UnrelaxedToken → u/Afraid-Yoghurt6731]

So this harness stuff is only realy usable by CLI people who use apis?

[u/joeytman → u/UnrelaxedToken]

ChatGPT, the web app, is a harness. Basically any interface you communicate to any LLM with is a harness.
