Four tools that run in your browser — convert a HAR recording or a script between JMeter, k6 and Gatling, open a results file without the GUI, scan a script for secrets before you share it. Nothing is uploaded; the page has no way to upload it. No account.
Scripting & Quality
Write better scripts faster. perf-script-studio turns a HAR recording or an existing script into a runnable JMeter, k6 or Gatling test, with the values that change between runs extracted. perf-lint enforces 53 rules across all three tools, and jmeter-cli-editor edits JMX without the GUI.
Execution
Run tests anywhere. perf-containers provides Docker images with 17+ protocol support, and perf-lab supplies the templates and the course that go with them.
Results & Reporting
Understand what happened. perf-reporting generates Apdex and SLA reports from raw JMeter, k6 or Gatling output, gates a build on them, and compares any two runs statistically — Mann-Whitney U and Cohen’s d.
Test Data
dummydatagenpro generates realistic, referentially intact test data in any format, through a web app or its API.
