What each one is
Windmill
Windmill turns Python, TypeScript or SQL scripts into workflows, schedules and internal apps, with AI steps as first-class citizens.
- Scripts first, UI generated for you
- Very fast execution engine

One plan: 7-day trial, then US$ 35/month for 3 months, US$ 70/month after. Note before using it: the page never says how 9bot attaches to a WhatsApp account, so the risk of the number being restricted cannot be checked.
- Setup and daily use happen in a web dashboard; the FAQ states no coding is required.
- An MCP server lets AI assistants and agents call 9bot tools for messaging, moderation.
- Content arrives automatically from RSS feeds, Twitch, YouTube and Kick alerts, APIs.
