For privacy-sensitive projects, always select 'Local Vault' or 'Git Sync' to avoid cloud storage. 3. Third-party plugins may not be fully reviewed; check ratings before installing.
Use Cases
- Debug and test REST, GraphQL, or gRPC APIs during development
- Collaborate with team via Git sync without relying on cloud storage
- Automate API testing and linting in CI/CD pipelines
