Best free AI agent builder (2026)

Forever-free tiers vs time-boxed trials, based on the 10 builders we track (checked 2026-10-16).

Not every "free" plan is the same. Some builders give you a lasting free tier (or free forever if you self-host). Others only offer a short trial or one-time credits. Below we split them using each vendor's own pricing pages.

Forever free (or free forever self-host)

These keep working after signup without a paid subscription — within plan limits. n8n's Community Edition is free to self-host; Make and Zapier Agents include ongoing free allowances; Activepieces, Botpress, and Dify Sandbox also have lasting free tiers.
