PocketStackA preview for every Compose PR

Add one GitHub Action. Browser-compatible Docker Compose pull requests receive a static, shareable preview; unsupported services receive a precise blocking report.

Add the GitHub Action
Check compatibility
See the examples

One pull-request workflow

The Action checks out the PR, analyzes Compose, generates static output, deploys a stable branch URL, and updates one PR comment.

Compatibility stays explicit

Arbitrary containers never masquerade as previews. Partial and blocked stacks fail the check and receive a static report with service-level reasons and suggestions.

Proven with real applications

A storefront, sprint board, and analytics dashboard demonstrate frontend, mock HTTP, PGlite, and static-web adapters through working interactions.

The contract ​

PocketStack publishes an application preview only when every active Compose service maps to a browser adapter. There is no Docker runner behind the URL.

Compose PR in. Static preview out—only when every service is browser-compatible.
