AI Testing that Writes, Runs & Maintains Tests for Every PR & Release
Makers of Orca (OSS Cursor) and Stably (AI testing platform)
Stably AI auto-writes, runs, and maintains end-to-end tests directly in your CI, guarding every pull‑request and production release—no flakiness, no test maintenance. Hundreds of modern engineering orgs already use Stably to merge code in minutes, replace brittle Playwright/Cypress suites, and slash QA spend by up to 80%. Stably offers - AI-generated test flows that mirror real user journeys. - Diff-aware execution—only tests affected by your change run, so CI stays under five minutes. - Automatic selector & assertion healing when your UI shifts, keeping the suite green. - Plain‑English editor letting PMs and QAs add tests without writing code. - One‑click GitHub App or API for instant pipeline integration.
We build devtools. Orca is an open-source Cursor—a local-first AI coding environment. Stably is our AI testing platform that writes, runs, and maintains E2E tests in CI. Developers use Orca and Stably to ship faster with more control—coding with their own AI setup and merging with confidence in minutes.
Stably AI expanded from just an AI testing platform to now also building Orca, an open-source Cursor (AI coding environment), representing a meaningful product expansion beyond their original focus.
