Lantern
Lantern — Serverless function performance monitoring for AWS Lambda including cold start analysis and invocation traces.
Our Verdict
Niche but useful if Lambda latency is your main pain; most teams will fold this into a broader observability stack instead.
Pros
- Focused on AWS Lambda cold starts and performance
- Clear, actionable invocation-level traces
- Faster to set up than generic APM on Lambda
- Complements existing CloudWatch tooling
Cons
- AWS Lambda only, no broader serverless coverage
- Very narrow scope versus Datadog or Dynatrace
- Small vendor, limited enterprise references
- Overlaps with newer native AWS features
When to Use Lantern
Good fit if you need
- Cold start duration tracking for AWS Lambda functions
- Invocation trace analysis for serverless bottlenecks
- Cost attribution per Lambda function and team
- Alert on memory and timeout threshold breaches
