Solo consultant ditches Zapier for custom Python stack, cuts per-client costs to under $2

A solo AI consultant based in Zürich replaced Zapier-based client automations with a custom Python and Postgres setup after finding that Zapier's pricing and task limits made serving multiple clients financially unviable. The consultant reports that per-client monthly costs dropped from around $50 to under $2 by running all workflows on a Hetzner CX22 server costing €4.50 per month. Beyond cost savings, the switch eliminated Zapier's minimum 5-minute polling delay, enabling sub-second triggers that improved client-facing user experience. The custom stack also provides a full audit trail via Git logs and database queries, addressing a transparency gap the consultant had experienced with Zapier's black-box execution. The main trade-off noted is an upfront investment of roughly three days to rebuild the first two or three workflows from scratch.
