Use Kiro with any AI provider
Kiro IDE with MITM. Pointing Kiro 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. Kiro is configured through MITM interception.
Why Kiro needs interception
Kiro has no setting for a custom endpoint — it talks to runtime.us-east-1.kiro.dev and nowhere else. kRouter runs a local proxy with a trusted certificate that intercepts just that host, so the app keeps working exactly as before while its requests are routed to whichever provider you mapped. Nothing leaves your machine except the upstream call.
Setup
Install kRouter
Install globally, then start it in the background.
Connect a provider
Open the dashboard and connect whichever providers you want Kiro to reach.
Point Kiro at kRouter
Enable Kiro interception on the CLI Tools page and map each model to a provider.
Model slots Kiro exposes
Each slot maps to whichever provider model you choose, so Kiro keeps its own naming while the request goes wherever you point it.

What changes for Kiro
Nothing about how you use Kiro 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 Kiro
Kiro shows a certificate warning
The local certificate has not been trusted yet. Run the trust step from the CLI Tools page — it installs kRouter's root certificate so the intercepted host validates normally.
Requests fail after MITM is turned off
Interception writes host entries while it runs. If it was stopped without cleaning up, those entries can point the app at a proxy that is no longer listening. kRouter detects this state and tells you how to clear it.
Kiro + kRouter FAQ
Can Kiro 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 Kiro can reach any of them without knowing they exist.
How is Kiro pointed at kRouter?
Through MITM interception. Kiro has no endpoint setting, so kRouter intercepts its traffic locally instead.
Does routing Kiro 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 Kiro keeps working instead of erroring out mid-task.
