Changelog

Today we're launching live scene catalogs — a single place to browse and open working copies of your product's most important flows.

Each scene you mark in your Playwright tests now shows up as a one-click instance. Share the catalog link with a teammate, a customer, or a stakeholder and they land directly in a working app, seeded with the exact browser state captured during your test run.

Nothing to spin up, no credentials to hand out — just a link.

We've made the first load of an instance noticeably faster. Warm machine pooling cuts cold-start deploy time roughly in half, so reviewers clicking a fresh link wait less before the app is interactive.

PR comments got an upgrade too: each scene now shows a live preview thumbnail alongside its description, so you can tell at a glance what changed before opening it. And you can now control how long instances are retained per workspace from settings.

The first published release of @midstream/sdk is out on npm.

• midstreamScene(page, slug) for the Playwright integration via @midstream/sdk/playwright.
• npx midstream <scene-slug> CLI for pausing at a scene while debugging locally.
• Zero-config CI auth using your existing GITHUB_TOKEN.

npm install --save-dev @midstream/sdk
