The short version

  • Each has a real cost: Serverless Framework exclusive to AWS Lambda - no support for other cloud providers; OpenTelemetry genuinely complex to adopt: collectors, pipelines, samplers and exporters are a system to run in their own right
  • They diverge on capability: Serverless Framework covers YAML configuration, OpenTelemetry covers Vendor-neutral SDKs.

What people use each for

The jobs each tool is most often brought in to do.

Serverless Framework

  • Building event-driven applications with serverless functionsnot OpenTelemetry
  • Managing multi-language serverless projectsnot OpenTelemetry

  • Instrumenting once and keeping the option to change observability vendor laternot Serverless Framework
  • Standardising telemetry across services written in different languagesnot Serverless Framework
  • Routing and filtering telemetry centrally to control observability spendnot Serverless Framework

Where each one falls short

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

Serverless Framework

  • Exclusive to AWS Lambda - no support for other cloud providers
  • Paid tier requires credit system that can be confusing for budgeting
  • Plugin ecosystem quality varies significantly

OpenTelemetry

  • Genuinely complex to adopt: collectors, pipelines, samplers and exporters are a system to run in their own right
  • Language SDKs mature at different rates, so a polyglot estate gets uneven support
  • It produces and moves telemetry but does not store or visualise it, so a backend is still required and still billed

Answered from the vendors’ own pages

Serverless Framework: When do I have to pay for Serverless Framework?

The Serverless Framework CLI v4+ is free for organizations earning under $2 million annually. Organizations earning more must purchase credits at $4 per credit standard rate or reserved credits starting at $1 per credit with volume discounts.

Source
OpenTelemetry: Is OpenTelemetry free?

Yes, open source under the CNCF. What you pay for is the backend you export to.

Serverless Framework: What cloud providers does Serverless Framework support?

Serverless Framework is exclusive to AWS Lambda. It does not support other cloud providers like Azure or Google Cloud.

Source
OpenTelemetry: Does OpenTelemetry replace Datadog or Grafana?

No. It replaces their proprietary agents and instrumentation libraries. You still need a backend to store and query the data.

Serverless Framework: What does one credit cover?

One credit equals 1 Service Instance, 50,000 Traces, or 4 Million Metrics.

Source
OpenTelemetry: Why adopt a vendor-neutral standard?

Because instrumentation is the expensive part. Once code emits OTel, changing observability vendor is a collector config change instead of re-instrumenting every service.
