Omnigres makes Postgres a complete application platform. You can deploy a single database instance and it can host your entire application, scaling as needed.
I started Omnigres because data-centric application development was getting more complex and I was seeking an antidote for that. I believe Postgres can be a great platform for such applications, especially considering its popularity. It needs a much improved DX and a constellations of extensions that would make it just perfect. That's Omnigres.
