Superfeedr vs Windmill

Superfeedr is a feed API for applications that publish content, consume feeds or monitor topics. It handles RSS, Atom and JSON feeds and delivers updates through real-time notifications, webhooks and open protocols including PubSubHubbub and RSSCloud. Publishers can use hosted hubs to notify subscribers, export subscriber information and review analytics such as subscriber counts, subscription counts and time periods. Pro Hubs add a custom CNAME, landing page and subscription controls. Subscribers submit feed URLs and receive Atom or JSON data through webhooks. Trackers search across millions of feeds using included or excluded terms, exact or fuzzy matching and language filters. Superfeedr uses push and ping methods to detect changes, while high-frequency feeds may still be checked every minute. Hosted Hub costs nothing. Subscriber use is free for fewer than 10 feeds in a month, then pay as you go. Tracker costs $2 a month per tracking feed, and Pro Hub costs $200 a month.

Windmill is an open-source workflow engine and developer platform for building endpoints, workflows and user interfaces. It is aimed at teams making internal software across engineering, data, sales, support and marketing. Scripts can be written in TypeScript, Python, Go, PHP, Bash, C#, SQL, Rust, Ruby and R, among other languages. Windmill combines a script editor, low-code flow builder, and low-code, React or Svelte app builders. Scripts and flows can be triggered by webhooks, schedules, HTTP routes, queues or an open API. Its Hub lists more than 200 resource types, including GitHub, Slack, AWS, BigQuery and PostgreSQL; users can also define custom resource types with schemas. Local development through the CLI and Git sync support version control and deployment workflows. Self-hosting is supported. The free and open-source plan is free and includes three workspaces, 50 users, 10 GiB of workspace object storage and 100 guest app users per 30 days. Enterprise is $120 a month and includes a month-long trial. Enterprise features include granular permissions, RBAC, secret management, OAuth, SSO and audit logs.
