A Potree Alternative With Nothing to Host
Potree is free, and that is a genuine advantage. SpatialSense trades that for a hosted service with BIM, issues, and documents built in.
What Potree does well
Potree is a free, open-source WebGL point cloud renderer built at the Institute of Computer Graphics and Algorithms at TU Wien, and it is a mature, widely used piece of software for exactly what it sets out to do: render very large point clouds in a browser with level-of-detail streaming, similar to how map software loads only the tiles a user can see. It includes real measurement and annotation tools, and reads LAS and LAZ files directly. This is the one comparison on this site where "free" genuinely is not something SpatialSense can claim against the competitor, and it would not be honest to pretend otherwise.
How SpatialSense and Potree compare
| Dimension | SpatialSense | Potree |
|---|---|---|
| Cost to use the core viewer | Paid plans from $99/month for real usage; the free tier browses sample data only | Free forever, open source |
| Hosting and setup | Fully hosted — sign up and open a scan | Self-hosted — data is converted with PotreeConverter and the viewer runs on a server you set up and maintain |
| Share a scan with someone with no setup on their end | Yes — sign up once, then share a link; no server to run | Requires the hosted Potree instance to already be running and reachable wherever it's linked from |
| Point cloud formats supported | PCD, LAS, LAZ, E57 | LAS and LAZ, plus its own converted format and Entwine Point Tile (EPT) |
| BIM overlay and issue tracking | Yes | Not part of the project; it's a point cloud renderer, with no BIM or issue-tracking features documented |
Where SpatialSense differs
Nothing to host or maintain
No server, no converter step, no version upgrades to manage yourself. The free browser point cloud viewer →
Pin issues to the model
Flag a problem on the exact point in the scan and assign it to someone. Annotate point clouds and assign issues →
Overlay against BIM
Put the as-built scan next to the design model in the same project. Verify as-built against BIM →
Compare scans over time
Line up two scans of the same site from different dates in one view. Compare point clouds across time →
The honest answer: if you have the engineering time to convert, host, and maintain your own viewer and don't need BIM or issues, Potree is a fine choice, and it costs nothing. If you'd rather sign up and share a link today, start a free trial.
