Debug locally. Share instantly.
Early accesspaid beta

Start free locally. Upgrade when debugging needs to leave your machine.

Falkenr is free for local debugging from GitHub. Do not create an account for the local dashboard. Create an account only when you want the paid Team beta: hosted relay access, teammate invitations, viewer sessions, and shared replay context.

If debugging looks like this
Can you reproduce this?
What request did you send?
Send me the logs
It works on my machine

Debugging breaks the moment it leaves one developer’s environment.

What if you could just send a link?

Your teammate opens the hosted session and sees the request, logs, config, and replay context needed to understand the issue. No staging deploy. No reproduction steps.

1. Hit an issue locally
2. Open /_dev
3. Click Share session
4. Send the link

Not a fit if
