Meet first, algorithm later.
This is how Casti begins
Natural connections that start with real encounters
Built for you
Tools designed for meaningful connections
Your own space
Create your personal space with photos, diary, and guestbook. See who visited and what they left behind.
Photo gallery
Organize memories by album and set visibility. Share with friends only, or keep them private.
Diary
Record your daily life with real-time sync across devices. Your entries are encrypted — only you can read them.
Communication
Stay connected through messages, guestbook, and emoji reactions. Messages disappear from the server once read.
15 friends
Save your relational energy. Casti connects you only with people who truly matter. The 15-person limit is intentional.
Nearby encounters
No algorithms — start with real encounters. Discover people in close proximity.
You are in control
Set your content visibility, with sensitive data encrypted.
E2E encryption
Diary and messages are encrypted — even the server cannot read them.
Read and delete
Messages are deleted from the server once received.
Visibility control
Control who can see your location, photos, and content.
