The short version
- Only OpenTelemetry has a free tier, so it costs nothing to try first.
- Each has a real cost: OpenTelemetry genuinely complex to adopt: collectors, pipelines, samplers and exporters are a system to run in their own right; RAD Studio professional edition costs $2,000 for the perpetual license plus $599 for year one maintenance, totaling $2,599 before tax

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
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
RAD Studio
- Professional edition costs $2,000 for the perpetual license plus $599 for year one maintenance, totaling $2,599 before tax
- Enterprise edition steps up to $3,400 license plus $1,199 maintenance, and Architect edition to $4,416 license plus $2,183 maintenance
- The perpetual license only entitles the buyer to updates for one year; continued access to new updates and upgrades requires an annually renewable Update Subscription

Questions people ask
- Is OpenTelemetry or RAD Studio better?
- Neither clearly leads. OpenTelemetry starts at Free and RAD Studio at $2000/perpetual, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
- Which is cheaper, OpenTelemetry or RAD Studio?
- OpenTelemetry has a free tier; the other does not. Paid plans start at Free for OpenTelemetry and $2000/perpetual for RAD Studio.
- Does OpenTelemetry or RAD Studio run on more platforms?
- OpenTelemetry runs on Linux, macOS, Windows, Kubernetes, Docker. RAD Studio runs on Web.
- Can I use OpenTelemetry for free?
- Yes. OpenTelemetry has a free tier, so you can try it without paying. RAD Studio starts at $2000/perpetual.
- What is OpenTelemetry best used for?
- OpenTelemetry is most often used for instrumenting once and keeping the option to change observability vendor later, standardising telemetry across services written in different languages, routing and filtering telemetry centrally to control observability spend. Of those, instrumenting once and keeping the option to change observability vendor later and standardising telemetry across services written in different languages are not what RAD Studio is typically brought in for.
- What can OpenTelemetry do that RAD Studio cannot?
- OpenTelemetry covers Vendor-neutral SDKs, Collector, Three signals, Auto-instrumentation.
Answered from the vendors’ own pages
OpenTelemetry: Is OpenTelemetry free?
Yes, open source under the CNCF. What you pay for is the backend you export to.
RAD Studio: How much does RAD Studio cost?
RAD Studio uses perpetual licensing: Professional Edition $2,000 perpetual license + $599 first year maintenance ($2,599 total + tax). Enterprise Edition $3,400 license + $1,199 maintenance ($4,599 total + tax). Architect Edition $4,416 license + $2,183 maintenance ($6,599 total + tax).
SourceOpenTelemetry: 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.
RAD Studio: What is the difference between RAD Studio editions?
Professional Edition ($2,599 total + tax) targets individual developers. Enterprise Edition ($4,599 total + tax) adds multi-tier app capabilities. Architect Edition ($6,599 total + tax) includes advanced database and cloud features. All three include perpetual licenses.
SourceOpenTelemetry: 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.
RAD Studio: Does RAD Studio offer Kai AI integration and discounts?
Yes, adding Kai AI to any edition provides discounts: 25% off Professional ($2,136 + tax), 30% off Enterprise ($3,394 + tax), and 40% off Architect ($4,109 + tax). This promotion is active through August 31, 2026.
