Compare Point Clouds Across Time
Did anything actually change since last month's scan? Right now, someone is answering that by flipping between two browser tabs.
Start free and compare two scans in the same view — no flipping between windows.

The change nobody can quite prove
Did anything actually change since last month's scan? Right now, someone is answering that by opening one viewer window, then another, and trying to hold both images in their head long enough to spot the difference.
It mostly works, until the change is small — a beam a few centimetres out of place, a wall that moved before the last scan caught it. Eyeballing two separate windows is not how you catch that.
Cross-timestamp comparison puts both scans in the same view, so the difference is something you see, not something you remember.
How it works
- Sign up free and load two scans of the same site, taken at different times.
- Open both in the comparison view.
- See what changed, measure it, and flag anything that needs a closer look.
More than a viewer
Measure in the browser
Distances and dimensions, checked directly in the viewer — no export to desktop software first. Measure point clouds in your browser →
Pin issues to the model
Flag a problem on the exact point in the scan and assign it to someone, instead of describing a location in a message. Annotate point clouds and assign issues →
Turn scans into progress records
A sequence of timestamped scans is already the record — no separate report to assemble. Turn site scans into progress records →
Share a link with your client
Send the comparison as a link — the recipient opens it straight in the browser. Share point clouds as a browser link →
Frequently asked questions
Is it really free?
Starting is free — sign up and explore the comparison view with sample scans. Uploading and comparing your own scans starts on the Starter plan, from $99 a month.
Is my data private?
Yes. Projects are private by default and access is role-based — only people you invite can open your scans.
What do I need to compare two scans?
Two scans of the same site, taken at different times, loaded into the same project. The comparison view lines them up so you can see what changed between them.
Which point cloud formats can I compare?
LAS, LAZ, E57, and PCD scans can all be compared, including scans in different formats from different equipment.
Does it work on mobile?
Yes — the viewer runs in a mobile browser, so a comparison opens on a phone or tablet in the site cabin as well as at a desk.
