The full answer
Almost all modern software relies on open-source components. Using mature, widely adopted projects means bugs are found and fixed quickly, documentation is plentiful and engineers who can work on your product are easy to find.
Not every library is a good choice. Before adding a dependency, Creuto considers whether it is actively maintained, how widely it is used, whether it has a history of security problems and whether its licence is compatible with how you plan to use and distribute your product.
Dependencies are scanned automatically in the CI/CD pipeline for known vulnerabilities, and updates are applied on a regular schedule as part of maintenance. This reduces the risk of an outdated library becoming a security issue.
Open-weight AI models such as Llama follow the same approach: licence terms and suitability are reviewed before they are used in a product.
Using open-source components does not affect your ownership of the custom code Creuto writes for you. A list of significant third-party components and their licences can be included in the handover documentation.
