Mosaikin vs Kululu (UK, 2026)
Both collect guests’ photos and videos from a QR code, with no app, into an album and a live slideshow. Kululu’s plans differ in uploads, upload window and how long photos are kept. Mosaikin takes video on every plan, checks every photo before it appears, and keeps a downloadable archive for 5 years on upgraded events.
Built in the UK, for UK celebrations. Run under UK law, with safeguarding built in as standard: every photo is checked before it is shown, and we report what the law says we must. You keep the lot, and share it as and when you like in a digital guestbook and album.

Where Kululu is ahead
- Unlimited uploads on its top plan. Every Mosaikin plan has a photo allowance.
- Original files on its paid plans. Mosaikin resizes a photo longer than 4096 pixels on its longest edge, which a typical phone photo is not.
- Captions and guest forms: guests can caption a photo, and Pro collects guest details on a welcome form.
Where Mosaikin is different
- Checked before it is shown, on every plan. Every photo and message passes a safety check, and anything uncertain waits for the host, without choosing a higher plan to switch moderation on.
- More than an album: a guestbook with a private note to the host, an invitation page with RSVP, and a scavenger hunt with missions and a leaderboard.
- Keepsakes beyond the download: a printable guestbook, a highlight reel and a word cloud on an upgraded event.
- UK law built in: reporting without an account, and child abuse material reported to the National Crime Agency. See trust.
