## What it is
Envconsul is a Go CLI tool that launches a subprocess with environment variables populated from HashiCorp Consul key-value data and Vault secrets. Applications remain unaware of the source, reading plain environment variables, enabling 12-factor-style portable configuration.

## Use cases
- inject vault secrets into app environment variables
- launch a subprocess with config from consul kv
- 12-factor app configuration without code changes
- populate env vars from vault at container startup
- run apps with secrets without exposing them in files
- dynamically refresh environment variables from consul

## When to choose
- you use HashiCorp Consul and/or Vault for config and secrets
- you want apps to read plain env vars with no SDK changes
- you need cross-platform secret injection with no runtime dependencies

## When to avoid
- you don't use Consul or Vault
- you need Kubernetes-native secret mounting instead
- you want a library to embed in-process rather than a subprocess wrapper
