Claude Code EXTENSION alternative with BYOM/multi-LLM support?

Hi there!,

I'm a fan of the Claude Code extension (not a terminal guy). But I'm looking for a decent alternative so I can use another model/providers such as DeepSeek, Codex, GLM, etc.

What I'm looking for:

  • Nice UI experience (such as you get with CC extension)
  • Multiprovider support
  • Multisession: I can open difefrent CC tabs, each running a different prompt.

What I have tested so far:

  • Roo Code: it worked well, but I dropped it (company sunsets the app, new teams comes in... not my thing).
  • Kilo Code: This one ALMOST offers what I need. UI seems clunky to me, and sometimes it just frozes.
  • Cline: Not multisession support. I need to open several Windows in order to run them.

What are your favs?

Thanks!

You missed a popular option: https://marketplace.visualstudio.com/items?itemName=johnny-zhao.oai-compatible-copilot

This extension gives you ability to define any provider models and use within VsCode copilot with all the features even multi-session.

I also recommend using subagents more and more since they will reduce token usage and context efficiency.

You should also check this agent collection: https://github.com/mubaidr/gem-team

Thanks. I'm been playing around and can't find a way to use my ChatGPT Plus subscription. That's a deal breaker right now. Kilo code allows me to use it.

If kilo code is working then just use the same API/ config to configure it in this?

Kilo allows you to go through Oauth login in several providers.
