Pricing that matches the question you are asking
Stresix charges per run, not per seat. One credit costs $2: a Standard run spends one credit ($2) and a Massive run spends three ($6). Pick the traffic level, run the test, and keep the setup recommendation. Credits come from capped campaign codes now, with paid checkout opening at launch.
Load tiers and what each run includes
| Tier | Concurrent users | Run window | Credits | Price |
|---|---|---|---|---|
| Standard | 2,500 | 10 minutes | 1 | $2 |
| Massive | 10,000 | 15 minutes | 3 | $6 |
How billing works
Each Standard run spends one credit, each Massive run spends three, and one credit costs $2 — so a Standard run is $2 and a Massive run is $6. Credits land in your balance through a promo code from a launch campaign, with paid checkout opening at launch. The ledger tracks every charge, refund, and redemption.
What a run returns
A run returns live percentiles (p50, p95, p99), throughput, error rate, and a clear next step for the load you sent. The recommendation is the point of the product: you leave with a number you can use on the next deploy.
What the hard limit protects
Every run has a maximum window of 15 minutes. When the window ends, the test stops, telemetry stays saved, and the test infrastructure is removed. No orphaned servers, no surprise bills.
undefinedFrequently asked questions
How much does a run cost?
One credit costs $2. A Standard run spends one credit ($2), a Massive run spends three ($6). Launch campaign codes grant credits free, and paid checkout opens at launch.
What does one credit buy?
One Standard run: 2,500 concurrent users for 10 minutes for $2, with percentiles and a setup recommendation at the end.
How is the recommendation decided?
From the measured percentiles, the error rate, and whether the app degrades under sustained load — compared against the tier that ran the test. You leave with the setup that fits the load you measured.
Can I test a private Docker image or repository?
Yes. Push an image to the private Stresix registry, or point at a repository and Stresix builds it in an isolated container before the run.
What happens after the run window ends?
The test stops and the test infrastructure is removed. Your telemetry and the recommendation stay in the workspace.
