- No vendor lock-in — workflows are portable JSON
FAQ
Frequently asked questions
Which AI agent is best for lead generation?
n8n is our top pick at 4.5/5. Onboarding checklists, approval routing, report generation — the long tail of processes nobody wants to build an app for.
Can an AI agent handle lead generation without supervision?
It depends on the agent and the stakes. 5 of the 14 agents here run fully autonomously; the rest keep a human in the loop. For anything customer-facing or irreversible, start with an approval step and remove it only once you have watched enough output to trust it.
Do I need engineers to set this up?
Not necessarily. Clay is cloud-hosted and configurable without code. Self-hosted and framework options in this list do require engineering time, but give you more control and lower per-run cost.
What does it cost to automate lead generation?
Entry pricing across these 14 agents ranges from free tiers to enterprise contracts. The bigger variable is the pricing model — per-seat costs are predictable, while credit- and consumption-based pricing scales with how much work you actually give the agent. Model your expected run volume before committing to an annual plan.
