The world's first software sleep aid

Sleep like a Baby
(Or at least a Senior Engineer)

Stably is the first pure-software sleep solution. We automate and maintain your E2E tests, so your PagerDuty app stays quiet and your REM cycles stay uninterrupted.

Hardware can't fix a broken login flow.

You bought the expensive cooling mattress. You took the magnesium. You put on the weighted blanket. But at 3:14 AM, the PagerDuty alarm goes off because a marketing intern changed the CSS class of the checkout button and your Cypress tests failed in production.

Your sleep architecture is fundamentally flawed. We fixed it at the source.

Technical Specifications

Not your average mattress cover.

Stably Hub / Cloud

  • AI-Powered Test Generation: Write in plain English, get resilient Playwright code.
  • Auto-Healing Engine: Drift detection automatically fixes broken selectors and prompts you to merge the PR.
  • Zero Hardware Leaks: 100% chance your bed stays dry.

Sleep Metrics

  • REM Optimizer: 80% reduction in false-positive test failures.
  • Deep Sleep Analytics: Video replays, DOM snapshots, and network logs for every failure.
  • Cortisol Reduction: Integrates directly with GitHub, Slack, and your CI/CD pipeline.
"I used to wake up in cold sweats wondering if the checkout button still worked. Then I got a cooling mattress, and I woke up in cold sweats, but comfortably cold. Finally, we installed Stably. Now I just sleep."

Features for better sleep hygiene

Auto-Healing Architecture

Like a smart thermostat for your codebase. Tests adapt to UI changes automatically while you dream about refactoring.

100% Cloud Slumber

No hardware to install. No messy water tubes. Just clean, reliable Playwright tests committed directly to your repo.

Deep REM Analytics

Wake up to beautiful, deterministic test run results and video replays, instead of "Error: Element not found" stack traces.

Ready to sleep through the night?

Join thousands of engineers who have reclaimed their weekends, stopped fighting flaky tests, and finally achieved full REM cycles.

* It's just a normal software trial, but "14-night" sounds more like a mattress company.
