Load testing tools built into your observability platform
Push your endpoints and APIs to their limits, watch latency percentiles and throughput in real time, and see exactly which errors and hosts break under load.
Know how your system behaves before your users do
Most teams discover their breaking point in production, on the worst possible day. Traditional load testing tools sit in a separate silo: you generate traffic in one place, then jump to a different dashboard to find out which service slowed down, which query timed out, and which host ran out of memory. By the time you correlate it all, the test window is over and the signal is gone.
AllStak runs stress and load testing inside the same platform that already tracks your errors, logs, traces, and infrastructure. Define concurrency and ramp-up, set pass/fail thresholds on latency percentiles and throughput, and run the test — then watch p50/p95/p99, error rate, and CPU, memory and disk on every host move together on one timeline. One platform, one bill, one place to find the bottleneck. The free tier lets you run your first load test today.
Everything you need to load test with confidence
From a quick smoke test to a sustained soak run, AllStak gives you the controls real load testing tools demand — and ties every result back to the errors and infrastructure behind it.
Concurrency & virtual users
Generate concurrent load against any HTTP endpoint or API. Set the number of virtual users and requests per second to model real traffic, from a handful of clients to heavy parallel load.
Ramp-up & load profiles
Ramp concurrency up gradually, hold a steady plateau, or spike traffic to find the cliff. Shape each run to match a launch, a sale, or a soak test instead of a single flat burst.
Latency percentiles
Track p50, p95 and p99 response times, not just averages. Percentiles reveal the slow tail your users actually feel, so you can tune the requests that matter most.
Throughput & error rate
Measure requests per second and successful throughput while watching HTTP error and timeout rates climb. See the exact load level where success starts to degrade.
Pass/fail thresholds
Set thresholds on latency, throughput and error rate so each run reports a clear pass or fail. Use them as release gates and stop regressions before they ship.
Correlate with errors & infra
Every run lines up with your error tracking, distributed traces, and host metrics. When latency spikes, jump straight to the failing trace, the noisy exception, or the saturated CPU behind it.
Run your first load test in minutes
- 1Point at your endpoint
Add the target URL, method, headers and body for the endpoint or API you want to test. Test a staging environment or a production-shaped replica safely.
- 2Shape the load
Choose how many virtual users and requests per second, set the ramp-up curve and duration, then define pass/fail thresholds on latency, throughput and error rate.
- 3Run and watch live
Start the run and watch p50/p95/p99, throughput, and error rate update in real time alongside CPU, memory and disk from your AllStak host agent.
- 4Find the bottleneck
When a threshold breaks, drill from the latency spike into the exact trace, error group, slow query or saturated host — all in the same platform, no context switch.
Why teams load test on AllStak
- One platform for load testing, errors, logs, traces and infrastructure — no extra tool, no extra bill.
- Root-cause in one click: latency spikes link directly to the failing trace, exception and host behind them.
- Percentile-first results (p50/p95/p99) so you tune for the slow tail your users actually experience.
- Pass/fail thresholds turn each run into a release gate that catches performance regressions early.
- Predictable SAR pricing and a free tier — start load testing without a procurement cycle.
- Saudi-based, with SAR pricing and a free tier.
Load testing FAQ
What is the difference between load testing and stress testing?
Load testing measures how your system behaves under an expected level of concurrent traffic, while stress testing pushes past that level to find the breaking point. AllStak supports both: hold a steady load profile to validate normal capacity, or ramp and spike concurrency until thresholds break to find your limits.
What metrics does AllStak report for a load test?
Each run reports latency percentiles (p50, p95, p99), average and peak response times, throughput in requests per second, the HTTP error and timeout rate, and an overall pass/fail against your thresholds. Because the test runs inside AllStak, those results sit next to your error groups, traces, and per-host CPU, memory, disk and network metrics.
Can I use load test results as a release gate in CI?
Yes. Define pass/fail thresholds on latency percentiles, throughput and error rate, and each run returns a clear pass or fail you can treat as a gate. This lets you block a deploy when a change makes p95 latency or the error rate cross the line you set.
Do I need a separate load testing tool alongside my monitoring?
No. AllStak is an all-in-one observability platform, so load testing lives in the same place as error tracking, logs, tracing, uptime and infrastructure monitoring. You avoid a second vendor, a second bill, and the manual work of correlating a load run in one tool with the errors and host metrics in another.
Is load testing available on the free tier?
Yes — you can start free and run a load test today, then move up as your needs grow. Pricing is in SAR and predictable, so you always know what scaling your testing will cost.
Will load testing affect my production system?
You control the target, the concurrency and the ramp, so you decide how much traffic to generate and where. Best practice is to test a staging or production-shaped environment first, then run controlled production tests during low-traffic windows with conservative thresholds in place.
