I'm the founder. It's a tool for interacting with deployment diagrams like you mentioned in your article.
We have customers who also model state machines and generate code from the diagrams.
What an interesting tool! It's rare to see robust data models, flexible UX abstractions for dev + ops, lightweight process notations, programmatic inventory, live API dashboards and a multi-browser web client in one product.
Do you have commercial competitors? If not, it might be worth doing a blog post and/or Show HN on OSS tooling (e.g Netbox inventory, netflow analysis of service dependencies) which offer a subset of Schematix, to help potential customers understand what you've accomplished.
Operational risk management consultants in the finance sector could benefit from Schematix, https://www.mckinsey.com/capabilities/risk-and-resilience/ou.... Lots of complexity and data for neutral visualization tooling.
Some of our best users are professional consultants who use us for a project which often introduces us to a new customer.
A Show HN would certainly be in order. Thanks for the thoughts!
