How to choose
Match the tool to your main constraint: agent autonomy, language specificity, or deliverability. Check whether you need zero-setup creation or full campaign assembly from an idea. Watch for tools that lock you into one language or require heavy integration work. Avoid assuming high upvotes equal broad fit; several strong options here have minimal votes yet solve narrow problems cleanly.
