Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Splunk
- No prices are published on any plan; every model requires contacting sales for an estimate
- Three separate pricing models, workload, ingest and entity, so the same deployment costs different amounts depending on which was signed
- Ingest pricing bills on data volume, so cost tracks how much you log rather than how much value you get from it
- Security, observability and platform are priced separately
Cloudflare
- Free tier limited to basic features (no advanced analytics or premium features)
- Pro tier ($20-25/month) caps at professional websites (higher tiers needed for enterprise scale)
- Caches only anonymous API GET responses (authenticated requests and non-GET methods not cached)
- Geographic coverage limited to announced 330+ cities (may not cover all regions globally)
