The short version

  • Each has a real cost: Deno Deploy smaller ecosystem compared to AWS Lambda with fewer third-party integrations; OpenTelemetry genuinely complex to adopt: collectors, pipelines, samplers and exporters are a system to run in their own right
  • They diverge on capability: Deno Deploy covers Edge Functions, OpenTelemetry covers Vendor-neutral SDKs.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

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

Deno Deploy

  • Smaller ecosystem compared to AWS Lambda with fewer third-party integrations
  • Less mature than established serverless platforms; newer company and platform
  • 1GB deployment size limit may restrict larger applications
  • 512MB memory limit lower than some competitors for memory-intensive workloads
  • Smaller user base and community compared to Lambda or Netlify

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

Deno Deploy: What does Deno Deploy's free tier include?

Deno Deploy free tier includes 1 million requests per month, 100 GB of outbound bandwidth, 50 milliseconds of CPU time per request, 50 custom domains, 1 GiB of KV storage, and up to 5 team members.

Source
OpenTelemetry: Is OpenTelemetry free?

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

Deno Deploy: What are Deno Deploy's Pro plan features and pricing?

Deno Deploy Pro costs $20/month and removes request limits, increases KV storage to 5GB, and includes priority support. Additional storage beyond 5GB costs $0.75/GiB.

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.

Deno Deploy: What are the deployment size and memory limits for Deno Deploy?

The total size of all files within a deployment (source files and static files) should not exceed 1 gigabyte. Applications have a maximum memory allocation of 512MB.

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.

Deno Deploy: Does Deno Deploy support TypeScript natively?

Yes. Deno Deploy runs TypeScript natively with zero-configuration TypeScript support. Code can be written in TypeScript or JavaScript and runs on the same V8 engine.

Source
Deno Deploy: What security features does Deno Deploy provide?

Deno Deploy features an opt-in permission system to mitigate supply chain attacks. Permissions can be explicitly granted for file, network, and environment access, running code securely by default.
