The JMeter paradox
JMeter earned its place: thread groups, timers, and assertions express real load semantics, and a generation of load engineers thinks in them. It is also a maintenance tax: sprawling XML, GUI-edited files that diff terribly, and plans that only one person on the team can safely touch.
Keep the semantics, lose the pain
Our performance engine keeps the JMeter mental model (thread groups, ramp profiles, timers, assertions) behind a UI that produces reviewable configuration instead of XML archaeology. Results ship with P50/P95/P99 and Apdex scoring by default, because a load test without percentiles is a vibe, not a measurement.
And because lock-in is the quiet cost of every platform decision, plans export to k6, JMeter, and Locust. If you leave, your load tests leave with you. We would rather earn the renewal than engineer the exit cost.
If you run JMeter today
- Import an existing plan through Migration Setup and compare the round-trip.
- Re-run your last load test and check the P95/Apdex against your previous tooling.
- Keep your JMeter exports in the repo. Portability you can verify beats portability promised.
How we measured this
- P50, P95, P99 and Apdex are computed by the engine from every sample in a run. Apdex follows the standard formula: satisfied requests plus half of the tolerating requests, divided by all requests, against the target time configured for the run.
