Open a .jtl results file and read the report
A JMeter .jtl is a CSV with a million rows in it and no summary. Drop one here and get the report: percentiles, Apdex, error breakdown, throughput over time and per-endpoint timings. It reads k6 JSON and Gatling simulation.log too, and it runs in your browser — the results file is never uploaded.
Open a results file nowWhat it handles
- JMeter .jtl and .csv, k6 JSON, and Gatling simulation.log
- Percentiles, mean, min and max, per endpoint and overall
- Apdex, scored on response time and outcome — a failed request is not a satisfied one
- Error breakdown by response code and by endpoint
- Throughput and response time over the run, so you can see where it turned
- Sanitises the report before you share it, replacing identifiers with placeholders and leaving every number exactly as it was
What it will not do
- One report in a browser tab is free forever. Running it on every build is not something a tab can do — that is what the CLI is for.
- Comparing two runs statistically, gating a pipeline on a threshold, and keeping a history across runs are Perf Reporting Pro features.
Questions
Is my results file uploaded?
No. It is read and rendered inside the tab, on an origin whose Content-Security-Policy forbids network requests. Results files routinely contain production URLs and sometimes response bodies, which is why this one is built the way it is.
How do I produce a .jtl?
Run JMeter in non-GUI mode with `-l results.jtl`. The default CSV format is what this reads.
Can I use this in CI?
Not this page — a browser tab cannot run on a build agent. Perf Reporting Pro is a CLI that generates the same report, compares runs statistically, and fails a build on a threshold you set.
Why does my Apdex look lower here than in JMeter’s own dashboard?
Because failures count. Scoring Apdex on elapsed time alone treats a fast error as a satisfied user, and errors are usually the fastest responses in the file. This scores outcome as well as time.
Try it on your own file
No account, no upload, no email address. It runs in the tab and stops when you close it.
