In many cases, your infrastructure may be sprawled from local development to cloud providers and CI/CD pipelines like you mention; you may have many environments each requiring their own set of secrets. This phenomenon is known technically as "secret sprawl" (see here for a fuller read: https://www.conjur.org/blog/what-is-secrets-sprawl-how-to-av...).

There's a lot of issues with secret sprawl but I think the relevant one to your specific question mentioning other cloud providers would be having missing secrets across infrastructure (you introduce a new secret to the codebase and forget to update it everywhere else, as well as communicate it or sync it through to other developers on your team) — applications crash, you lose time.

A big idea in secret management amongst others is the idea of *centralizing* your secret management in one place — update here, update everywhere. We help achieve that across your entire infrastructure and have a handy dandy CLI that also helps you inject secrets back into your programs (achieving secret management for local development with zero application dependencies) if you need that :D

I may be misinterpreting your question actually — Unless you mean why use Infisical versus other alternatives on cloud providers like AWS Secret Manager / Parameter Store, Azure Key Vault, etc?

They gave some reasons at the top.
