Visual workflow automation — the hub that wires every other tool on this list into one pipeline.

What it is
Visual workflow automation — you connect boxes on a canvas instead of writing glue code, across 400+ services, with AI steps built in. Self-hosted Zapier, with no per-task pricing.
Why it matters
Every other tool here is a component; this is the assembly line. New video published → pull the transcript → Claude writes a blog post, a description, timestamps, an X thread and a LinkedIn post → generate the Russian versions → queue everything in Postiz. Built by dragging boxes. For someone running marketing solo, this is the line between doing something once and having it happen every week forever. It will also quietly watch Reddit and Hacker News for anyone discussing chat summarisation or scalping strategies and tell you.
- Visual, so it's buildable and — more importantly — debuggable without being a developer
- Fixed VPS cost regardless of volume, unlike Zapier
- Claude Code can generate the workflow JSON for you to import
- Not OSI open source — fine for your own business, but you can't resell it as a service
- Resource-hungry; a busy instance competes with Grasppy for RAM
- Easy to start, surprisingly fiddly to debug once workflows get long — and an AI-heavy loop can quietly burn API money
