Ember.js Octane | Node.js | Scala | Playwright | Puppeteer | Postman | AWS | Load Testing SaaS
Testable.io is a distributed load testing platform trusted by Deutsche Bank, RBS, Adidas, and Mastercard. The platform supports Playwright, Puppeteer, Selenium, JMeter, Gatling, and dozens of other testing tools across 100+ cloud regions. ISO 27001 certified, it scales to millions of virtual users. We've been their development partner for over 5 years, working across Ember.js frontend, Scala backend, and Node.js testing agents.

This partnership began when we helped upgrade legacy Ember to Octane edition. We incrementally migrated components from outdated patterns to modern Ember Octane architecture, ensuring zero downtime throughout the transition. What began as an Ember.js upgrade evolved into full-stack platform development.
We built and maintain the Node.js Test Runner Agents that power Testable's distributed testing. These agents integrate with Playwright, Puppeteer, and Postman, allowing users to run their existing test scripts at scale without modifications. The agents coordinate with the Scala backend to distribute load across cloud regions.
One of the most technically challenging features we delivered: recording video from headless Chrome instances running inside virtual servers with no GUI. Users can now watch exactly what happened during their test runs, even when browsers spawn across distributed infrastructure. This required deep integration with the test runner architecture.
We've built significant admin panel functionality including a complete code editor (SLIM IDE) for editing test scripts directly in the browser, complex visualization graphs for comparing test results across runs, and most recently, monitoring tests infrastructure for ongoing test health tracking.
We developed a native macOS application that automates Testable installation, downloading all necessary components and configuring the local environment. Users can set up their Mac as a test runner node without touching the command line.
