Workflow Automation (n8n, Make, Zapier)
Not every problem needs a free-roaming agent. Often you want repeatable, auditable steps — and that is the home of no-/low-code automation platforms. They are where most teams first put LLMs to productive work.
- Place a task on the automation-to-agency spectrum and pick the right tool for it.
- Know when a deterministic workflow beats a free-roaming agent.
Not every problem needs a free-roaming agent. Often you want repeatable, auditable steps — and that is the home of no-/low-code automation platforms. They are where most teams first put LLMs to productive work.
Platform | Best at | LLM/agent story |
|---|---|---|
Zapier | Fast, simple trigger → action links across 8,000+ apps | Zapier Agents add autonomous, Copilot-built helpers |
Make | Visual, branching scenarios with a "glass-box" view | Make AI Agents orchestrate across 3,000+ apps |
n8n | Source-available, developer-grade workflows you can self-host | Native AI Agent node mixing deterministic steps with reasoning |
The key idea is a spectrum. At one end, a Zapier-style automation runs a fixed trigger → action path: utterly predictable, no judgment. In the middle, an n8n or Make workflow adds branches, loops, and an LLM as one step — you still own the control flow. At the far end, an agent is handed a goal, tools, and memory and chooses the steps itself.
Example. "When an invoice email arrives, extract the total and log it to a sheet" is a perfect deterministic workflow — never make that an agent. "Investigate why this customer churned and draft a win-back plan" is open-ended — that is where agency earns its cost. n8n explicitly recommends mixing the two: deterministic steps for reliability, an agent step where genuine judgment is needed, with human approval in between.
