How Chromoly Builds Apps: Blueprint, Review and Runtime
Chromoly separates the description of an app from the shared machinery that renders and runs its supported features. The saved blueprint gives planning, compilation and change review a common structure.
The underlying principle
AI interprets the requested system and proposes a blueprint or edits. The blueprint describes pages, records, APIs and workflows. Shared runtime components implement supported behaviour. A structured definition can include executable logic; it should not be presented as proof that no generated code or runtime error is possible. Product definition.
From request to working preview
- Describe the users, content, records and actions the app needs.
- Review the proposed result and any missing configuration.
- Generation applies structure and behaviour checks; larger builds can use saved phases.
- Inspect the preview with representative records and test the important paths.
- Configure external services and review the result before deployment.
How edits are reviewed
The change review compares the saved version with the generated candidate. It shows additions, modifications, removals and dependent features. The dependency map connects blueprint elements such as fields, APIs, components, pages, workflows and roles. Review and dependency map documentation.
Why use a shared structure?
A common representation helps locate related parts of the app and apply consistent components. It also defines a support boundary: a requested feature must be expressible and supported by the platform. A visual match to a demo is not evidence that an unsupported integration or workflow will run.
What to compare with other approaches
Evaluate the visibility of changes, the supported app patterns and the operating model. Code-oriented tools may offer different extension and collaboration options. Chromoly’s approach is a product choice, not proof that dependency analysis or safe release processes are unavailable elsewhere.
Operational limits still matter
Static analysis cannot see every dynamic relationship or external effect. Saved-version restoration does not reverse data edits, messages or payments. Connected services need their own credentials and tests. Managed implementation and maintenance are agreed separately; consult current availability before committing to a rollout. Workflow operations; plans and service scope.
Frequently asked questions
What does the compiler build from?
The saved AppSpec blueprint describes supported app structure and behaviour. The compiler and shared runtime use that definition to assemble the app.
Does the architecture guarantee a production-ready app?
No. Generated output requires review, representative behaviour tests, permission checks and configuration of connected services before use.
