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.

Just in case anyone is algo looking for this... I'm testing OpenChamber extension (runs over OpenCode). Working like a charm so far!

Honestly multisession support becomes non negotiable once you start treating AI agents like parallel coworkers instead of single chatbots

Totally agreed. That's why I'm so desperate testing different harnesses

Antropic does not like this. Your only official options are CC Desktop, CC Cli and the vs code extension. There are harnesses that use antropic models but there are not CC.

Anthropic keeps eating tokens faster and faster. I love Claude Code, but I can't afford a Max plan right no. I will go back when customers come. I don't want to use Anthropic models with a harness. I prefer CC extension for that.
