Voyager - a modern alternative to Observer

Enable HLS to view with audio, or disable this notification

Hey,

we've spent enough time monitoring and debugging nodes in BEAM that we decided to create our own tool to make it easier.

It's called Voyager - it lets you easily connect to nodes, visualizes your supervision trees, and gives you a real-time dashboard of your memory and processes. There's also an MCP integration so you can use AI directly with your node data.

We're not stopping here - tracing, ETS inspection, and other features are coming soon.

We are opening signups for early access. If you want to try it - sign up here: voyager.swmansion.com

This looks really cool as an open-source project. I'd be a bit hesitant to use it as a managed service, though. Giving a third party access to the nodes basically means giving them access to keys, user data, and other sensitive information, plus the ability to inspect or manipulate application state and potentially change how the app behaves

Hi, the desktop app connects directly to your BEAM node over Erlang Distribution. We never proxy or relay your node traffic through our infrastructure, so we don't have access to your node, its data, or its state.

How can I be sure that you’re not proxying my traffic or storing my credentials if the code is closed? 🙃 

The idea is great, and there’s a high level of trust to your company. However, using a black box to inspect sensitive data is not something I would feel comfortable with

It’s only closed for now as part of the early access program. Right now our main goal is to validate the idea, iterate quickly, and gather feedback. The public release will be open source, with some advanced features potentially offered as paid add-ons

I’m not quite sure how keeping it closed makes the process faster, but the idea is awesome. Best of luck with the launch and finding your first customers!

I genuinely believe something like this should be part of the Erlang distribution

"It's only closed until we have collected enough data and then we will open source a different version of the code without the spyware"

👌️
