Coralogix
- No self-hosted option; cloud-only SaaS requiring use of customer's AWS, Azure, or GCP infrastructure
- Pricing is purely usage-based per GB with no flat-rate subscription option; suitable for unpredictable workloads but no cost ceiling
Fluent Bit
- Fluent Bit ships over 100 built in plugins against more than 1,000 external plugins available for Fluentd, so fewer integrations exist out of the box
- It is written in C, so extending it beyond the built in plugins means writing C rather than Ruby
- Dependencies are zero only until a plugin requires one
