## What it is
Apex Hammer is an automated Salesforce platform process rather than a self-service tool. Before each major release, Salesforce runs an org’s Apex tests in both the current version and the upcoming release and compares the results, flagging behavior changes in custom code ahead of the upgrade. Admins can review Apex Hammer execution status for their org in Setup.

## Choose it when
- Load Testing scenarios across typical web and service stacks
- Organizations budgeting for commercial licenses or subscriptions
- Groups comfortable scripting in Apex

## Look elsewhere when
- Strictly air-gapped environments with no approved cloud path
- Projects that require a fully free open-source stack only

## Architecture
Apex Hammer runs as a cloud service: scenarios use Apex, while generators and orchestration are vendor-managed.

## Pricing
Included as part of the Salesforce platform service, not a standalone paid product.

## FAQ
### Who is Apex Hammer for?
Apex Hammer is best for engineers designing load, stress, and performance tests for web and service systems. It is commercial software, typically licensed for larger or governed programs. Vendor: Salesforce. Deployment model: cloud. Bundled with the Salesforce platform; operated by Salesforce rather than sold separately.

### How does Apex Hammer differ from Apache JMeter?
Compared with Apache JMeter, Apex Hammer is commercial while Apache JMeter is open source; deployment is cloud versus self-hosted for Apache JMeter; scripting centers on Apex rather than Java, Groovy. Apex Hammer lists protocols not recorded; Apache JMeter lists HTTP, HTTPS, JDBC, JMS, FTP, TCP. Status is active versus active. Use the Test Rig to compare full specs side by side before a proof-of-concept.

### What scripting language and concurrency model does Apex Hammer use?
Apex Hammer uses Apex for scripting or scenario definition. Runtime model: protocol-oriented virtual users configured through the product workflow. OS support: Browser. Protocols: not recorded. Match these to how your team already authors tests and which systems you must drive under load.

### What is the cloud or enterprise path for Apex Hammer?
Apex Hammer is cloud-hosted: you run tests on vendor-managed infrastructure without operating load generators yourself. That usually speeds ramp-up for distributed load while shifting capacity planning and data residency to the vendor. Pricing model: Bundled with the Salesforce platform; operated by Salesforce rather than sold separately.

### What are known limitations of Apex Hammer?
Apex Hammer limitations to weigh: cloud services trade operational simplicity for vendor pricing, data residency, and network path differences versus your production topology; commercial licensing and quotes can gate large-scale or enterprise use; protocol coverage is not fully recorded in this catalog entry. Status: active. Always validate against your target protocols and scale with a proof-of-concept.
