Engineers
Keep your Playwright workflow, review every diff in Git, and cut flaky reruns.
Features
Everything needed to keep browser tests reliable in production
From plain-English planning to CI execution and test upkeep, Stably gives teams one system for dependable release checks.
Stably never changes your tests silently. Your team reviews and approves updates.
QA / PM
Describe what to test in plain language and share evidence-backed run results.
Plan tests faster
Write tests in plain English or have an AI assistant draft a first pass.
Run tests reliably
Get stable release checks with visual proof and clear pass or fail interpretation.
Fix drift and real bugs
Separate test upkeep from product regressions so the right owner acts quickly.
Describe what you want to test in natural language. Stably turns it into a structured test plan with clear steps, expected outcomes, and coverage hints.
Anyone on your team can create test coverage without writing code. Engineers review and approve — no black box.
- Step-by-step test plans generated from natural language
- Coverage gaps highlighted before you write any code
- One-click export to Playwright-ready test files

Stably generates real Playwright test code from your plain-English plans. The code lives in your repo, passes code review, and runs with standard Playwright tooling.
No vendor lock-in. No proprietary framework. Your tests are portable Playwright code that any engineer can read, review, and modify.
- Clean Playwright code generated from your test plans
- Git diffs you can review like any other PR
- Smart selectors that prefer role-based locators over brittle CSS

test('checkout flow', async ({ page }) => {
await page.goto('/pricing');
- await page.click('.trial-btn');
+ await page.getByRole('button', { name: 'Start free trial' }).click();
await page.fill('#email', 'user@test.com');
+ await expect(page.getByText('Order confirmed')).toBeVisible();
+ await expect(page.locator('[data-testid="order-id"]')).not.toBeEmpty();
});
Selector rationale: Uses role-based selectors with fallback to data-testid for reliability.
Run your Playwright tests in parallel across browsers and environments. Get a clear pass/fail signal you can trust — no more re-running to see if it passes this time.
Flaky tests destroy confidence in your test suite. Stably gives you a reliable release signal so you can ship with confidence.
- Parallel test runs across browser and environment combinations
- Failures grouped by root cause, not scattered across logs
- A clear release-ready signal for every build

When your app changes, Stably automatically fixes broken selectors and test steps. When there's a real bug, it tells you — with evidence.
Stop wasting hours triaging failures that turn out to be stale selectors. Stably separates real regressions from test maintenance so your team focuses on what matters.
- Automatic classification: test maintenance vs. real product bug
- Suggested fixes with clear reasoning you can review
- One-click approve or reject for every suggested change
