clstr

Create a personal wall for experiences and share each as its own link. clstr lets you build a wall of your experiences. Every trip, concert, weekend, or milestone becomes its own page on your wall with photos, videos, and the people who were there. Friends who shared the moment can add their photos next to yours, and visitors can leave you notes. You design the wall yourself by arranging and resizing cards, splitting a photo across a bento grid, adding songs and text posts, and styling everything to feel like you. The more you live, the fuller it gets. Share the whole wall with one link or send a single experience on its own. Your wall has its own address: [yourname].clstr.life. Free, no app needed. There's a live demo wall at https://emma.clstr.life View startup

Build real distributed systems from scratch, one stage at a time. Each stage is verified by tests that simulate network failures, crashes, and real-world conditions.
