Supported targets and trusted timestamping are useful criteria when considering release compatibility. AWS Signer, Cosign, and SignPath are among the options shown. The listed comparisons also include free-plan availability and paid-from pricing; weigh these against the signing capabilities and key protections relevant to your release setup.
