The short version

  • Each has a real cost: CloudCompare the project is administered by its creator in his spare time while he holds a full-time job elsewhere, so an organisation building a monitoring programme on it depends on one person with no obligation to continue; Milvus vector dimensions are capped at 32,768
  • They diverge on capability: CloudCompare covers Cloud to cloud distance, Milvus covers Billion-scale vectors.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

CloudCompare

  • The project is administered by its creator in his spare time while he holds a full-time job elsewhere, so an organisation building a monitoring programme on it depends on one person with no obligation to continue
  • There is no commercial support contract from anyone, so a defect that blocks a deliverable is resolved by a GitHub issue and community goodwill rather than by an agreement
  • Processing is single machine and memory bound, so very large aerial lidar collections must be tiled manually and large jobs are limited by the workstation rather than scaled out
  • The interface is unforgiving and organised around the underlying data structures rather than around tasks, so competent surveyors routinely take weeks to become productive
  • Plugins vary widely in maintenance, and several useful ones originated in research projects that have since ended, so a workflow built around a specific plugin can break at the next release

Milvus

  • Vector dimensions are capped at 32,768
  • A collection is limited to 64 fields, 1,024 partitions and 16 shards
  • Only 1 index is allowed per field
  • Search returns at most 16,384 vectors as top-k, and nq is capped at 16,384
  • Input and output per RPC is capped at 64 MB for insert, search and query
  • VARCHAR values are limited to 65,535 characters
  • Data loaded into query nodes cannot exceed 90% of available memory
  • An instance supports at most 65,536 collections

Can I use CloudCompare for free?
Both have a free tier, so you can try either at no cost before committing.
What is CloudCompare best used for?
CloudCompare is most often used for a monitoring engineer comparing quarterly laser scans of a retaining wall to quantify movement without buying a proprietary deformation package, a heritage team registering dozens of terrestrial scans of a building into a single cloud before meshing, a geomorphologist measuring erosion between two drone-derived surfaces of a river bank, a survey technician cleaning and subsampling a scan before delivering it to a client whose software cannot handle the full density. Of those, a monitoring engineer comparing quarterly laser scans of a retaining wall to quantify movement without buying a proprietary deformation package and a heritage team registering dozens of terrestrial scans of a building into a single cloud before meshing are not what Milvus is typically brought in for.

Answered from the vendors’ own pages

CloudCompare: Who maintains CloudCompare?

Daniel Girardeau-Montaut, its creator, administers it in his own time alongside a full-time engineering job, with contributions from a community of users and research groups.

Milvus: How much does Milvus cost?

Milvus is open-source and free to use and modify. The self-hosted version has no licensing cost. Zilliz Cloud (the managed SaaS version) does not publish pricing on the website.

Source
CloudCompare: Can I buy support?

No. There is no vendor and no commercial support offering. Some geospatial consultancies know it well and can be hired, but they are not contracted to support the software itself.

Milvus: Is there a free or open-source version of Milvus?

Yes, Milvus is fully open-source and available for free. Milvus Lite is a lightweight option for learning and prototyping that can be installed via pip.

Source
CloudCompare: Is it suitable for commercial deliverables?

It is widely used for them. The licence permits it and the algorithms are well regarded. The risk is operational, not legal: no support and no roadmap commitment.

Milvus: Does Milvus offer a managed cloud service?

Yes, Zilliz Cloud is a fully managed Milvus cloud offering with serverless and dedicated cluster options. Pricing must be requested from the company as it is not listed on the public website.

Source
CloudCompare: Can it handle a full aerial lidar survey?

Not in one piece. It is memory bound on a single machine, so large collections need tiling or a dedicated lidar pipeline such as PDAL.
