16 auto DM tools, judged on the only number that matters.
Every tool here says "free". They mean very different things by it. Below is what each free plan actually allows, read from each vendor's own pricing page rather than from other people's comparisons.
Quick answer
Of 16 Instagram DM automation tools checked on 1 September 2026, only three advertise a free plan with no monthly DM cap: Peerseek Auto DM, WhoseDM, and SuperProfile, which is uncapped on Reels and Posts only. Peerseek is the only one of the three that covers every trigger including story replies, includes follow-gating that SuperProfile and Zaprep charge for, and sells consultations, webinars and digital products from the same account. Every other tool caps free usage at 1,000 DMs a month or less, and ManyChat stops at 25 active contacts.
Free plans, side by side.
Ranked by how far the free plan gets you before it stops. Prices are monthly-billed unless noted.

| 2.SuperProfile AutoDM | Unlimited AutoDMs on Reels and Posts, with a link-in-bio store included. | Partly | Only 3 keyword triggers and 10 lead-magnet responses. Story, Live and DM triggers, follow-gating and email capture all need the paid plan. | $29/mo |
| 3.ReplyKaro | 1,000 DMs per month on 1 Instagram account, 3 active automations. | No | Hard 1,000 DM ceiling. One viral reel can clear it in an afternoon. | $3/mo |
| 4.LinkDM | 1,000 DMs per month on 1 Instagram account. | No | Free is limited to your last 10 posts, carries LinkDM branding, and comment auto-reply needs Pro. | $19/mo |
| 5.CreatorFlow | 500 DMs per month on 1 Instagram account, with unlimited keyword triggers. | No | 500 DMs is roughly one strong reel, and it resets rather than rolls over. | $15/mo |
| 6.ManyChat | 25 active contacts per month, up to 2 channels, up to 4 automations. | No | Counted per person, not per message, so 25 people ends the free plan regardless of volume. | $17/mo |

Questions, answered
What is the best free Instagram auto DM tool in 2026?
Three of the 16 tools checked advertise uncapped free DM volume: Peerseek Auto DM, WhoseDM, and SuperProfile. Peerseek is the only one that is uncapped across every trigger including story replies, allows 20 keyword triggers, and lets you sell consultations, webinars and digital products from the same account. SuperProfile is uncapped only on Reels and Posts with 3 keyword triggers; WhoseDM is a much newer, smaller tool offering automation alone. Everything else caps free usage: ReplyRush 1,500 DMs/month, ReplyKaro, LinkDM, BlazeReply, Grohubz and Zaprep 1,000, CreatorFlow and Kwikzy 500, SendDM 300, DMlite 200, and ManyChat 25 active contacts.
Is there a genuinely free ManyChat alternative with no contact limit?
Yes. ManyChat's free plan allows 25 active contacts per month, after which you move to Essential at $17/month. Peerseek Auto DM has no contact tier and no DM ceiling at any volume, so a reel that draws 2,000 comments sends 2,000 DMs at no cost. Peerseek earns a flat 5% only when a DM turns into a paid booking or sale.
Do these tools work outside India?
Peerseek Auto DM works anywhere Instagram's official API is available, and signup accepts international phone numbers. Paid selling through Peerseek settles through Indian payment rails, so creators outside India can use Auto DM free but cannot yet take payouts. ManyChat, LinkDM and CreatorFlow are all global. ReplyKaro is India-first with global plans.
Will using an auto DM tool get my Instagram account banned?
Not if the tool uses Meta's official Instagram API. Every tool in this comparison connects through Instagram's OAuth login rather than asking for your password, which is the approach Meta sanctions. The tools that carry real risk are the ones that ask for your Instagram username and password directly, or promise automated likes and follows. Auto DM is not a growth or follower tool.
How was this pricing verified?
Every figure on this page was read directly from the vendor's own pricing page on 1 September 2026, with the monthly and annual billing toggles checked separately. This matters more than it sounds: most published comparisons quote annual-billed prices as if they were monthly rates, which understates the real monthly cost by 20 to 30 percent.
Which tool should I pick if I want to sell from my DMs?
Peerseek, because the booking page, webinar, digital product and payment collection are part of the same account rather than an integration you assemble. With the other tools you automate the DM, then send people to a separate checkout you host elsewhere. If you only need the DM to deliver a link and nothing more, any tool here will do it.
