Where they pull apart

n8n

Stands out: Billing counts full workflow executions, not individual steps, and the Community edition is free to self-host.

Watch out: Cloud prices are published in euros only. The Cloud trial is capped at 1,000 executions, and unused AI Assistant credits do not roll over.

Not the right fit for

Buyers who need a USD Cloud price
Non-technical users who will not work with nodes

Onetab AI

Stands out: The HR Agent phones shortlisted candidates itself, up to 50 calls at once according to the vendor, scores the answers and passes only qualified people to a recruiter. Every agent step shows in the thread and is logged with a person attached.

Watch out: No price is published above the free tier for five users, so budgeting needs a sales call. The credit plans on agents.onetab.ai are for Onetab's separate personal assistant, not this team product. Speed figures such as 73% faster time to hire are the vendor's own.

Not the right fit for

Buyers who need a published per-seat price before a demo
Recruiters who only need an ATS, not a chat workspace

Performance figures on the site are vendor claims
