Maelstrom

Maelstrom is an advanced load testing and performance testing platform built to help organizations uncover weaknesses before they impact users. Unlike legacy tools that rely on synthetic pings or limited stress testing scenarios, Maelstrom delivers hyper-realistic performance testing at global scale. It emulates real browser sessions, APIs, SIP traffic, and DNS activity to provide accurate insights into how modern digital infrastructures behave under pressure. This ensures that web applications, cloud services, and enterprise systems are tested under the same conditions customers generate in the real world. By replicating sudden traffic spikes, region-specific surges, and complex multi-protocol interactions, Maelstrom empowers DevOps, SRE, and engineering teams to identify performance bottlenecks, scalability limits, and potential system failures. These realistic stress testing simulations allow teams to strengthen infrastructure resilience, optimize response times, and reduce the risk of costly outages. Maelstrom doesn’t just generate data—it provides actionable insights. Test results are presented in a way that enables teams to quickly pinpoint root causes, prioritize fixes, and validate improvements. Instead of lengthy static reports, Maelstrom makes performance validation a continuous and agile process. Key benefits include: Comprehensive load testing that goes beyond HTTP to cover APIs, voice/SIP, and DNS. Global performance testing at scale, simulating millions of virtual users. Actionable, real-time insights for remediation and optimization. Resilience validation, ensuring systems remain reliable under peak conditions. With Maelstrom, organizations can confidently stress test their infrastructure before it’s tested by customers—or attackers. By combining realism, scale, and precision, Maelstrom redefines what’s possible in modern load and performance testing, turning reliability and scalability into a competitive advantage.

Speedscale

Speedscale captures real production HTTP, gRPC, and SQL traffic inside your own Kubernetes cluster and turns it into a closed AI-agent loop: discover → spec → triage → reproduce → validate → PR. Nothing leaves your environment. Bring Your Own Everything. The capture agent, traffic store, and replay engine run as a Kubernetes operator in your cloud — not ours. You bring your apps, your storage, your AI models (private Anthropic, self-hosted Llama, in-house — whatever your compliance posture allows), and your governance controls. Speedscale orchestrates the loop without locking you to any cloud, model vendor, or storage tier. The closed AI-agent loop. When a production failure occurs, the eBPF capture agent records the exact request — full payload, headers, SQL statements, all dependent traffic. An AI triage agent specs the problem, classifies it, and routes it. A reproduction agent replays the identical traffic against your current codebase in a non-production environment to confirm the failure. A validation agent verifies the fix before the PR is opened. Human review is optional at every stage — run fully autonomous or fully human-gated. Same product, different governance. proxymock — the developer entry point. Teams start with proxymock, a free CLI that stands in for downstream dependencies using recorded production responses. AI coding agents (Claude Code, Cursor, GitHub Copilot) query captured production traffic through the MCP integration, giving them real-world context — actual failed requests from your environment — instead of synthetic test data. Enterprise data residency. For regulated industries — financial services, healthcare, payments, regulated retail — production API payloads cannot leave the enterprise environment. Speedscale's BYOC architecture is the only production-traffic-capture approach that satisfies this constraint without sacrificing the payload fidelity needed for AI-driven bug reproduction. Speedscale is used by engineering teams at Home Depot, IHG (InterContinental Hotels Group), FLYR, Cimpress/Vistaprint, Navitaire (an Amadeus subsidiary), and Ascension Health.
