# Web Performance, Inc.

> Enterprise load testing company since 1999, based in Durham, NC. Web Performance helps organizations ensure their websites and applications can handle expected and peak traffic loads. WPLoadTester runs inside the customer's own AWS account on the customer's own AI keys, so EC2 costs flow directly to the customer and there is no per-VU-hour SaaS markup.

## Products

### WPLoadTester
Enterprise load testing software that scales to 1 million concurrent virtual users. Differentiators:
- **Bring Your Own Cloud (BYOC)**: load engines spin up inside the customer's AWS account. EC2 costs flow directly to the customer; no SaaS compute premium.
- **Bring Your Own AI (BYO-AI)**: uses the customer's Anthropic, OpenAI, or AWS Bedrock key. No new vendor security review, no markup on AI tokens.
- **AI auto-configuration**: paste a URL, the AI Assistant identifies auth flows (PKCE, OAuth, form login), writes the test, and runs it. What used to take days now takes minutes.
- **The system learns**: when the AI solves a correlation problem, the fix is saved as a persistent detection rule in ASM (Automatic State Management), the expert system refined since 1999. New recordings get the accumulated rules applied before the AI is invoked, so the same problem is never paid for twice. Knowledge lives in deterministic rules, not an ever-growing prompt file.
- **AI-written performance reports**: trained on 500 anonymized real-world performance reports written by Web Performance engineers. Plain-English narrative, severity ranking, root-cause hypotheses.
- **Flat license model**: at 100,000 virtual users × 4 hours, per-VU-hour SaaS pricing runs ~$60,000. WPLoadTester runs flat license + ~$77 of EC2.
- **No-coding approach**: WebDriver/Selenium recording, replay at the protocol level, no scripting language to learn.
- **Free edition**: most features work free on one computer, forever; cloud load generation and AI reports require a license.

## FAQ

**How much does WPLoadTester cost at scale?**
At 100,000 virtual users × 4 hours, per-VU-hour SaaS competitors charge ~$60,000. WPLoadTester runs the load engines inside the customer's AWS account: a flat license fee plus ~$77 of EC2. See https://www.webperformance.com/load-testing-tools/your-cloud/ for the math.

**Is there a free version?**
Yes. Most features work free on one computer, forever, with no signup or credit card. Cloud load generation and AI-written reports require a license.

**What AI providers are supported?**
Anthropic (all Claude models), OpenAI, and AWS Bedrock. The customer brings their own API key — Web Performance never sits in the middle, never sees prompts, never stores data. Existing enterprise AI contracts apply; no new vendor review.

**How many virtual users can WPLoadTester simulate?**
Up to 1 million concurrent virtual users, distributed across cloud or local load engines.

**Do I need to write code to create load tests?**
No. WPLoadTester records real browser actions via WebDriver/Selenium and replays them at the protocol level. The AI Assistant handles auth flows (PKCE, OAuth, form login), session state, and variable correlation automatically.

**Does WPLoadTester's AI learn over time?**
Yes, through the expert system. When the AI Assistant solves a correlation or session-state problem, the fix is stored as a persistent ASM detection rule. Every new recording gets the accumulated rules applied automatically, before the AI is invoked, so repeat problems cost zero AI tokens. The learning is stored as deterministic rules rather than growing prompt context, so it never degrades AI consistency.

**Where does test traffic originate?**
From load engines that run inside the customer's AWS account in regions the customer chooses — typically outside the target's region so traffic takes the same internet path a real user's request would. Traffic never leaves the customer's cloud boundary.
