The short version
- Only Comet ML has a free tier, so it costs nothing to try first.
- Each has a real cost: Comet ML the free cloud tier caps data at 25,000 spans a month with 60 day retention; Katana limited BOM explosion and lead-time offset planning requiring manual work that should be automated
- They diverge on capability: Comet ML covers Experiment tracking, Katana covers Production planning.
Where they differ

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Comet ML
- The free cloud tier caps data at 25,000 spans a month with 60 day retention
- Retention stays at 60 days even on the paid Pro plan, and extending it is a $29 per 100k spans add on
- Overage on Pro is $5 per additional 100,000 spans
- The free MLOps tier is a single user with 100 GB of storage and training hours governed by a fair usage policy
- Pro MLOps is $19 per user per month and caps the team at 10 users
Katana
- Limited BOM explosion and lead-time offset planning requiring manual work that should be automated
- No native invoicing capability, making it standalone without accounting system integration
- Limited native integrations, with heavy reliance on Zapier for non-core tools
- Slow performance with large datasets and high SKU counts

Answered from the vendors’ own pages
Katana: What is Katana's pricing structure?
Katana starts at $99/month for the Essential plan with core MRP features. The Pro plan costs $299/month and adds shop floor control and API access. Add-ons for traceability, manufacturing, and warehouse management cost extra and can reach $747-$1,095 total.
SourceKatana: Does Katana support multi-level bills of materials?
Katana has limited BOM explosion and lead-time offset planning capabilities. Complex multi-level BOMs with sub-assemblies require manual workarounds, which becomes increasingly problematic as SKU count grows.
SourceKatana: Can Katana integrate with my accounting software?
Katana has no native invoicing capability and limited integrations with accounting systems. It is essentially standalone and requires manual data export or Zapier integration for most accounting workflows.
SourceKatana: Does Katana have an offline mode?
No, Katana is a cloud-only solution requiring internet connectivity. There is no built-in offline mode for production floor access without internet.
