BlazeMeter vs Gatling

From $149 per month (indicative entry plan)

From €89 per month (indicative, Enterprise Cloud entry)

Priced by concurrent virtual users. Large enterprise tests are a substantial annual commitment.

Open source is free; Enterprise adds distributed injectors and reporting, billed by virtual-user-hours.

Free tier with a small virtual-user cap and limited test duration.

Gatling open source is complete for single-machine load generation.

• Runs your existing open-source scripts unchanged — no migration cost.
• Global load generation from many regions without owning infrastructure.
• Reporting and trend analysis suited to handing results to management.

• Very high throughput per load generator thanks to the async architecture.
• Code-first scenarios that review, diff and refactor properly.
• The default HTML report is genuinely good enough to hand to a stakeholder.

• Expensive relative to running the same open-source scripts on your own machines.
• Virtual-user pricing makes frequent large tests costly.
• Adds a vendor to a workflow that can function entirely on open source.

• Historically Scala-first; the Java and JavaScript DSLs are newer and less documented.
• Fewer protocols than JMeter.
• Distributed load without the enterprise product means building your own orchestration.

Enterprises with existing JMeter estates that need scale and reporting without building it.

JVM teams wanting code-first performance tests with excellent reporting.
