Starpl ✦
A star from the night sky, for you.
Starpl — the star that holds you
A small space to place your star on the map, write your days onto it, and stay close with star friends.
Starpl gives you a star of your own in the night sky. Write your days onto that star, and stay quietly connected with kindred people across the star map.
It is not a dot drawn on a screen — it is a real, observed star with its own Tycho-2 number, truly shining somewhere in the night sky.
You choose who sees each record — public, star friends, or only you. It works as a private diary no one else can read, or as a small SNS shared with your star friends.
Starpl carries the memory of the 2008 starpl.com — "a star that holds you", a service that began at Wecon Communications and closed long ago, now rebuilt by one of its former team members. It inherits the feel of the old Starpl as an homage. Rather than a dazzling plaza, we will keep working to make this a place you want to stay long and return to.

Built with open source
Starpl stands on the shoulders of countless open-source projects. From star data to the web framework and the database — without tools shared so freely, this star could never have risen. We cannot name everyone, but we offer our deep respect and gratitude to every open-source developer.

Who made this
Starpl is a small service built slowly by one person (with Claude). It aims to be a star that stays for the long run, rather than one chasing fast growth.
