Pick Zapier Agents if
- Your processes already run on Zaps, and every app involved is one of Zapier's 9,000+ integrations.
- You want agents to share an organisation's Zapier account, connections and enterprise audit logs (Agents Enterprise).
Pick Kaer if
- Part of the job is a website with no Zapier integration and no API: Kaer works it in its own browser, like a person would.
- You want approval gates on the consequential step, an audit log of every action, and the run isolated on its own machine.
- You want the tool that does not exist yet built for you, not just connected.
Kaer vs Zapier Agents: common questions
Is Kaer a Zapier alternative?
For work an assistant does, yes; for wiring apps together with fixed triggers, Zapier is the established choice. The difference is reach: Zapier Agents act only in apps you have connected, while Kaer also operates websites that have no integration.
Can I use both?
Yes. Kaer works alongside the tools you already run; a Zap can keep doing the app-to-app plumbing while Kaer takes the jobs that need a browser, judgement or an approval.
How do the free plans compare?
Zapier's Agents Free plan includes 400 activities a month (Zapier's pricing page, read 3 October 2026). Kaer's Starter plan is free with 20 messages every day and needs no card.
