Make offers substantially more logic per pound than Zapier: a proper canvas with routers, iterators and error branches, at a fraction of the per-operation cost. The trade is a steeper learning curve and a smaller app library.
Best for technical teams needing self-hosting or high volume
n8n is the technical team's automation platform: a capable visual builder that lets you write code where needed, and a self-hosted edition with no per-execution cost. Setup and maintenance are yours to own.
Pipedream is an integration platform aimed squarely at developers: prebuilt components where convenient, Node, Python, Go or Bash where not. Enormously productive if you code, largely pointless if you do not.
