By personal start page, I mean a custom-made web page that you would set as the home page in your browser and use it as the starting point of doing things in the browser.
I'm considering building something with Next.js or Gatsby that I can self-host, but I'd love suggestions of the most customizable tools that would allow me to quickly integrate data "widgets" from diverse sources like Nextcloud, Fastmail, RSS readers (Inoreader, maybe), CalDAV, bank accounts, etc.
The goal for any portal site was to convince you to spend more time on the portal (this is how we got {Yahoo,Google} news). The more time on the portal was more ad impressions they could sell. Social media didn’t like sharing content this way and so portals became significantly less popular.
I’d forgotten how much I’d missed those.
