The first stable release of the official Postscale CLI is available for macOS,
Linux, and Windows.
- Configure domains, inspect DNS records, and verify email authentication.
- Send API-native JSON from a file or stdin, or validate it locally with
--dry-run. - Inspect outbound messages, delivery events, received email, and webhook attempts.
- Use named OS-keychain profiles or environment credentials, with JSON output
and explicit test/live credential context for scripts.
Download the archive for your platform and verify its SHA-256 against
checksums.txt. Each archive contains the CLI, README, license/notices,
changelog, and sample message. Prebuilt binaries do not require Go.
Go 1.25+ users can install with:
go install github.com/postscale/postscale-cli/cmd/postscale@v1.0.0See the installation and usage guide.
Known limits: auth status checks local configuration, email inspection uses
resource UUIDs, and mutations are never automatically retried. The pinned SDK
omits newer response environment fields; inspect context.credential_environment
and data.status. Webhook forwarding, batch sending, and deletion are not included.
Built with Go 1.25.11. Binary downloads are unsigned; checksums.txt provides
SHA-256 integrity verification. See CHANGELOG.md.
