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.
