Where each one falls short

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

Sentry

Spending caps stop event ingestion when reached, eliminating visibility during critical moments
Complex configuration required for filters, sampling rules, issue grouping, and alert policies
Difficult to configure custom alerts and alert content without creating email inbox bloat
Error grouping is imperfect with noise and filtering issues causing incorrect error prioritization
Weak for distributed tracing across microservices compared to dedicated APM tools
UI dashboard is less customizable than alternatives like Datadog APM for complex monitoring needs

Skopeo

Single-purpose: it neither builds nor runs images, so it is one tool in a chain rather than a solution
Command syntax with transport prefixes such as docker:// is unusual and trips people up initially
Documentation is sparse compared with the rest of the container ecosystem
