TrigyfyTrigyfy vs LinkDM
LinkDM is a well-known Instagram comment-to-DM tool with tiered send limits per plan. Trigyfy takes a simpler approach: one Pro plan, no DM cap.

Which one should you use?
Both tools run on Instagram's official API for the same comment-to-DM workflow, but LinkDM's entry Pro ($19/mo) is nearly double Trigyfy's ($9.99/mo). The gap widens on volume: every LinkDM tier caps your monthly DM count, so high volume pushes you toward the $99 plan, while Trigyfy's Pro stays unlimited at a flat $9.99. LinkDM offers a permanent free tier (1,000 DMs/month); Trigyfy matches it with a free plan (1,000 replies + DMs/month) plus a 14-day full-access Pro trial.
