The short version

  • Only OpenTelemetry has a free tier, so it costs nothing to try first.
  • Each has a real cost: Heroku there is no free dyno tier; the cheapest Eco dyno is $5 per month; OpenTelemetry genuinely complex to adopt: collectors, pipelines, samplers and exporters are a system to run in their own right
  • They diverge on capability: Heroku covers Git-based deployment, 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.

Heroku

  • There is no free dyno tier; the cheapest Eco dyno is $5 per month
  • Eco dynos sleep after 30 minutes of inactivity, are restricted to personal accounts and allow only 2 process types
  • Free SSL and 10 process types start at the Basic dyno at $7 per month
  • Private and Shield dyno types require a Private Space, which is billed on top of the dynos
  • Private Space dynos start at $250 per month for Private-M and $500 per month for Private-L
  • Dyno prices are per dyno per month, so an app with several process types multiplies the bill

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

Heroku: How much does Heroku cost?

Heroku dyno pricing starts at $5 per month USD for the Eco tier (with 30-minute inactivity sleep), $7 per month for Basic (always-on), and scales up to $1,500 per month for Performance-2XL with 126 GB RAM.

Source
OpenTelemetry: Is OpenTelemetry free?

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

Heroku: What is the cheapest always-on Heroku plan?

The Basic Dyno at $7 per month USD is Heroku's cheapest always-on container option. It provides 0.5 GB RAM, free SSL, and support for 10 process types.

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.

Heroku: How is Heroku Postgres priced?

Heroku Postgres Essential tier (shared resources) starts at $5-$20 per month for 1-32 GB disk. Standard tier (dedicated) ranges $50-$12,000 per month. Premium, Private, Shield, and Advanced tiers offer higher performance at corresponding prices.

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.
