Loadster is a load testing, stress testing, and monitoring platform for websites, web applications, and APIs. Create realistic test scripts and play them back with thousands of virtual users to find bottlenecks, improve performance, and prevent crashes. You can record load test scripts right in your browser with the Loadster Recorder extension for Chrome or Firefox. Just step through your site like a real user would while Loadster records every step into a script. After recording, play your script back in real time, making edits as necessary. It's simple to add custom validation and capture server responses to reuse later in the script. Configure your test scenario with groups of bots in regions of your choosing, running your scripts, ramping up the load. Load test your site to prepare for your next traffic spike, and monitor it continuously to detect problems quickly. Your site has a breaking point. Find it before your users do!

AI bug repair from real production traffic, run entirely in your cloud. Speedscale captures HTTP, gRPC, and SQL traffic via eBPF inside your Kubernetes cluster. Production payloads never leave your perimeter. When a failure occurs: the capture agent records the exact request, a triage agent classifies it, a reproduction agent replays it against your codebase, and a validation agent verifies the fix before the PR opens. Fully autonomous or human-gated. You supply the cloud, storage, and AI models (Anthropic, Llama, or your own). Speedscale orchestrates the loop with no cloud, model, or storage lock-in. proxymock: free CLI giving AI coding agents (Claude Code, Cursor, Copilot) real production context via MCP. No signup required. Meets PCI and HIPAA data-residency requirements. Used by Home Depot, IHG, FLYR, Cimpress/Vistaprint, Navitaire, and Ascension Health.

Appvance IQ (AIQ) delivers transformational productivity gains and lower costs in both test creation and execution. For test creation, it offers both AI-driven (fully machine-generated tests) and also 3rd-generation, codeless scripting. It then executes those scripts through data-driven functional, performance, app-pen and API testing — for both web and mobile apps. AIQ’s self-healing technology gives you complete code coverage with just 10% the effort of traditional testing systems. Most importantly, AIQ finds important bugs autonomously, with little effort. No coding, scripting, logs or recording required. AIQ is easy to integrate with your current DevOps tools and processes. Appvance IQ was developed by a pioneering team who envisioned a better way to test. Their innovative vision has been made possible by applying differentiated, patented AI methods to test creation while leveraging today’s high-availability compute resources for massive levels of parallel execution.
