Overview

Stably is an AI-powered QA testing product for web applications. It turns plain-English test descriptions into Playwright coverage, then runs those tests in the browser or in CI so teams can automate release checks without building every test by hand.

The site presents Stably as a workflow for planning, creating, running, and fixing tests. It supports a no-code platform, terminal use, and CI execution, and it emphasizes reviewable outputs such as screenshots, traces, recordings, and proposed updates when tests drift.

Core capabilities

Plain-English test creation

Write test intent in plain English or import it from docs and tickets, then generate explicit Playwright coverage that can be reviewed before it runs.

Cloud and CI execution

Run tests in Stably Cloud or in your CI, with screenshots, traces, and recordings available to inspect failures and results.

Visual editor with code sync

Build tests visually in the editor and sync changes back to Playwright code so QA and engineering can work from the same test source.

Plan, run, and repair workflow

Use the plan, create, run, and fix flow to generate new suites, execute existing tests, and propose updates when test drift appears.

Reviewable governance controls

Review generated changes instead of accepting silent edits, with audit trail, role-based controls, and approval-oriented governance on enterprise-oriented workflows.

Shared workflow inputs

Connect testing work to broader product context by bringing in Jira, repos, and docs for shared test cases and rollout alignment.

Common use cases

Draft browser tests faster
Teams can describe a test in plain English, generate coverage, and review the explicit steps before it is committed to a release process.
Validate releases in CI
QA and engineering teams can run existing tests in CI and inspect screenshots, traces, and recordings when something fails.
Work visually, keep code in sync
Teams that prefer a visual flow can build tests in the editor, then sync them back to Playwright for version-controlled collaboration.
Handle test drift
Organizations with changing products can use the fix-and-review workflow to update brittle tests and surface likely real bugs for human review.
Coordinate testing across teams
Cross-functional teams can share testing context across Jira, repos, and docs so test coverage aligns with product work.

Provides reviewable artifacts such as screenshots, traces, and recordings.
Includes a fix-and-review flow for test drift and likely product bugs.
Uses transparent credit-based pricing with a free starting tier.

Cons

The public site does not provide a full integration catalog or technical setup details.
Pricing is credit-based, so ongoing usage depends on browser time and model tokens rather than a flat unlimited package.
