The short version

  • Each has a real cost: Bruno native Git integration, the feature that distinguishes it from cloud API clients, is Pro only at $6 per user 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: Bruno covers API Testing, 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.

Bruno

  • Native Git integration, the feature that distinguishes it from cloud API clients, is Pro only at $6 per user per month
  • OpenAPI syncs are capped at 5 a month on the free tier
  • SSO, SCIM and user management require Ultimate at $11 per user per month
  • Private workspaces are a paid feature
  • Advertised prices are annual rates

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

Bruno: What is included in Bruno's free tier?

The Open Source plan includes the core API client, limited Git integration, and up to 2 workspaces at no cost. A 14-day free trial of the Ultimate plan is also available without requiring a credit card.

Source
OpenTelemetry: Is OpenTelemetry free?

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

Bruno: What is the difference between Bruno Pro and Ultimate plans?

Pro ($6/month) includes native Git integration and unlimited workspaces. Ultimate ($11/month) adds SSO/SCIM support, audit logs, 24-hour support (vs. 48-hour), and an account manager. Ultimate supports unlimited OpenAPI syncs while Pro is limited to 5 per month.

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.

Bruno: How much does Bruno Pro save compared to other API tools?

The vendor claims Ultimate saves teams more than 70% versus Postman, though this comparison is promotional rather than a specific cost metric.

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.
