There are alternatives to n8n depending on your stack of what is being orchestrated. Node-red, and others have quietly existed for a very long time, similar to how n8n existed for a good while before being discovered by the AI world.
I think that's a critical argument that n8n and others will have to overcome - why should users decide to over-specialise one aspect of their stack when they can do so much more and have so much more control elsewhere?
One for the many, and maybe one for a different audience.
Node-red didn't have a login at the time, and was well geared towards direct IoT type flowing. I loved how I can just jump into the logic and flows.
N8N has a lot of pre-configured connectors.
If Node-red had the pre-configured connectors to different systems as easy as n8n, I think the point here would be even stronger.
It's why I use both. I start with the low level, and if orchestration beyond it is needed, I can tie in another tool if needed.
