The verdict
If you ship code, pick GitHub. Almost every software team needs it, and Pipedream does not replace any part of it. Pick Pipedream as well only if you are building an agent or product that must act inside each customer's Slack, Gmail or CRM, and you do not want to build OAuth flows yourself. In that case the two work side by side. Do not choose Pipedream as a visual workflow builder for your own team, and do not start a new automation project on its old Workflows product. For that need, look at Zapier, Make or n8n. If nobody on your side writes code, neither tool is for you.
