Use jcode with any AI provider

High-performance Rust-based coding agent harness. Pointing jcode at kRouter gives it 100+ providers behind a single local endpoint — free tiers, subscriptions you already pay for, and paid APIs — with automatic failover when one runs out. jcode is configured through a config file.

Note: jcode is a Rust-based coding agent with semantic memory, multi-agent swarms, and extreme performance (27.8 MB RAM, 14ms boot).

Note: Configure kRouter as an OpenAI-compatible provider to route all jcode requests through kRouter's optimization layer.

Heads up: Requires jcode installed. Install via: curl -fsSL https://raw.githubusercontent.com/1jehuang/jcode/master/scripts/install.sh | bash

Setup

  1. Install kRouter

    Install globally, then start it in the background.

  2. Connect a provider

    Open the dashboard and connect whichever providers you want jcode to reach.

  3. Point jcode at kRouter

    Set the base URL to http://localhost:20128/v1 and paste a kRouter API key.

Model slots jcode exposes

Each slot maps to whichever provider model you choose, so jcode keeps its own naming while the request goes wherever you point it.

What changes for jcode

Nothing about how you use jcode changes — same interface, same workflow. What changes is where its requests land. Instead of being tied to one vendor and one bill, every request goes through your own machine first and out to whichever provider you mapped: a free tier for routine edits, a subscription you already pay for on the heavy turns, a paid API only when nothing else fits. When one account hits a limit, the next takes over mid-session rather than failing the task. And because the router runs locally, your prompts are not passing through a third-party service on the way.

Troubleshooting jcode

The config file change has no effect

Confirm you edited the file the tool actually reads — some tools keep separate global and project configs, and the project one wins. Restart the tool after editing.

Model not found after switching

Model ids are provider-prefixed here (provider/model). Call GET /v1/models against kRouter to see the exact ids your connected providers expose.

jcode + kRouter FAQ

Can jcode use providers other than its default?

Yes — that is the point of routing it through kRouter. kRouter presents one OpenAI-compatible endpoint that fans out to 100+ providers, so jcode can reach any of them without knowing they exist.

How is jcode pointed at kRouter?

Through a config file. Nothing about jcode itself changes — it still speaks the same API.

Does routing jcode through kRouter cost anything?

kRouter is free and MIT-licensed and adds nothing to your bill. What you pay is whatever the provider you routed to charges — which is often nothing, if you route to a free tier or a subscription you already hold.

What happens when a provider runs out of quota mid-session?

kRouter parks that account until its real reset time and fails over to the next one you have connected, so jcode keeps working instead of erroring out mid-task.
