Methodology

• Only tools whose official pricing page confirms a free plan or free trial are included.
• Each claim is logged with source URL and access time (last check 2026-10-22 UTC).
• No rankings, reviews, or ratings are invented; 'best for' pages filter by category, not quality.
• Excluded: tools where a free trial could not be confirmed (e.g. Goodcall offers a demo agent, not a trial).
