The best free Instagram DM automation tool depends on which unit its free plan counts. Nine tools ship a tier that never expires, and no two of them count the same thing: SuperProfile and Zorcha send without a volume limit, GRO.co is free below 15K followers, ReplyRush allows the most of the DM-metered tiers at 1,500 a month, LinkDM allows 1,000, CreatorFlow and InstantDM 500 each, ManyChat and Inro count people instead of messages, and inDM meters nothing on either plan.
So "which one is free" is the wrong question, and almost every roundup answers it anyway. Ranking free tiers on price alone puts nine identical zeroes in a column. What separates them is the meter, and the right tool is the one whose meter does not sit across the thing your account already does. Below is what each free tier includes, read off the vendors' own pricing pages with the date we read them.
Which Instagram DM automation tools have a free tier?
Nine do, on terms that don't expire, ours included, and it is listed below rather than left out of a table it belongs in. Two more have a free tier too small to run anything on, and two have none for Instagram DM automation at all.
| Tool | Free tier | What it meters | Read |
|---|---|---|---|
| SuperProfile | $0 forever, AutoDMs on Reels and Posts with no stated cap, 10 leads | Leads captured | 2026-08-08 |
| GRO.co | $0: free for accounts below 15K followers, Instagram only, unlimited posts, no card | Your follower count | 2026-08-12 |
| ReplyRush | $0, 1,500 DMs/mo, 1 Instagram + 1 Facebook. No comment auto-reply, no follow gate | DMs sent | 2026-08-08 |
| LinkDM | $0: 1,000 DMs/mo, 1 Instagram account, LinkDM branding on | DMs sent | 2026-08-08 |
| inDM | $0: unlimited DMs, no card, every automation type, 1 Instagram account | Nothing, no meter on either plan | ours |
| CreatorFlow | $0, 500 DMs/mo | DMs sent | 2026-08-04 |
| InstantDM | $0: 500 DMs/mo, Reels and Story automation | DMs sent | 2026-08-12 |
| Zorcha | $0: 15,000 AI credits, 3 automations, DMs uncapped | AI credits | 2026-08-08 |
| Chatfuel | Chatfuel Light: free, no card, Instagram/Facebook/WhatsApp automations | Not published | 2026-08-08 |
| Inro | €0, 100 contacts activated/mo | Contacts | 2026-08-04 |
| ManyChat | $0, 25 active contacts/mo | Contacts | 2026-08-04 |
| BotPenguin | Free forever: 1,000 messages/mo, but Instagram DM automation starts on the $29/mo plan | Messages, all channels | 2026-08-08 |
| Spur | None. Cheapest plan is $12/mo | , | 2026-08-08 |
Two entries in that table are the useful ones, because they are the two nobody writes down. BotPenguin's free plan exists and does not include Instagram DM automation. That starts at $29/mo. And Spur has no free tier at all. A roundup that lists thirteen tools and marks eleven of them "free" is counting plan names, not capability.
What does a free DM automation tier actually cost you?
Usually one of four things, and it is worth knowing which before you build a funnel on it.
Their name on your DM. LinkDM's free plan carries LinkDM branding; ReplyRush keeps its branding through the $10 tier and removes it at $25; GRO.co removes branding on the $30 plan. This is the most common price of free in the category, and it is charged in the one place your audience is actually looking. The message that arrives from you.
A ceiling you hit on a good day. 500 DMs a month is roughly one reel that does well. The free tiers are sized for a quiet month, which means the day the automation earns its keep is the day it stops.
The trigger you needed, missing. ReplyRush's free plan has no comment auto-reply and no follow gate. Comment-to-DM is the single most common reason to want one of these tools, so a free plan without it is free in the way a car without wheels is cheap.
A cap that is real but written as "unlimited." InstantDM's $9.99 plan is described as unlimited automation, and its own comparison table qualifies that as 750 per hour. That figure is not a product limit, 750 private replies per hour per account is Instagram's own documented ceiling, which every tool on this page is subject to whether or not it says so. It is fair to say their "unlimited" is the platform's number restated. It is not fair for anyone, us included, to promise past it.
Why can't you compare two free tiers directly?
Because six of them meter six different things, and there is no exchange rate between them.
- DMs sent: CreatorFlow, InstantDM, LinkDM, ReplyRush. Every message the tool sends on your behalf counts.
- Contacts: ManyChat, Inro. One person costs the same whether you exchange one message or forty, and the count resets monthly.
- AI credits: Zorcha. DMs are uncapped; the meter runs on the AI features instead.
- Messages across every channel: BotPenguin. Your Instagram volume shares a budget with WhatsApp and web chat.
- Your follower count: GRO.co. Free below 15K followers, then priced in audience bands up to 3M.
- Leads captured: SuperProfile. The sends aren't the meter; the people are.
A "1,000 DMs" allowance and a "100 contacts" allowance are not two sizes of the same thing. Under the two-message opt-in flow that Instagram requires for links, one converted comment costs two DMs, an opener, then the link after the person taps. So 1,000 DMs is around 500 conversations, while 100 contacts is 100 people no matter how much they message you. Work out which unit your own use case is denominated in before comparing any two numbers on this page.
Which free tier fits what you are doing?
Match the meter to the shape of your account, not the headline.
- Under 15K followers and posting consistently: GRO.co's free plan is unmetered on volume and priced on the one number you're trying to grow. That is a good deal now and a decision to revisit at 15K.
- One reel a month that does well: a DM-metered free tier will hold. 500 to 1,500 DMs covers a couple of hundred conversations.
- A small, chatty audience you talk to a lot: a contact-metered tier is the better shape, because forty messages to one person costs the same as one.
- You need comment-to-DM specifically: check that the free tier includes it. ReplyRush's does not, and it is the most common reason people arrive here.
- You need Instagram DM automation from a multi-channel tool: check it is on the free plan at all. BotPenguin's is not.
Where does inDM sit?
We have a free plan that doesn't expire (unlimited DMs, no card) as of 2026-08-16, replacing the 1,000-a-month allowance introduced four days earlier. The honest note is that it's new, and several tools in the table above got to a free tier first, unlimited free sending included.
What's in it: every automation type, unlimited keywords, the follow gate and the email capture gate, automation and audience analytics, the unified inbox, contacts and export. Nearly everything is on both plans, which is the opposite of the pattern in "What does a free tier actually cost you?" above, where the missing trigger is usually the price. Paid is $14.99/month, or $4.99 for a first month, and it adds no volume: it removes the app branding, connects up to 5 Instagram accounts, and shows you who opened your links and the countries they came from, three of the things it adds.
None of the message arithmetic further up this page applies to your inDM bill, because there is no bill to apply it to. However many messages a converted comment takes, none of them is counted. Set against the table: unlimited free sending puts us level with SuperProfile and Zorcha rather than ahead of them, and ahead of CreatorFlow's 500 and LinkDM's 1,000. Where LinkDM sells branding removal at $19, we sell it at $14.99.
Updated 2026-08-16, and the update is the whole answer. When this post was written our free plan was 1,000 DMs a month with an optional badge that made an automation unmetered. That structure is gone. The free plan now sends without any limit, on one connected Instagram account, and removing app branding moved onto Growth at $14.99.
Branding removal is where this category actually differs, and it is worth comparing on price: LinkDM removes it at $19, ReplyRush at $25, GRO.co at $30, inDM at $14.99. SuperProfile is the outlier worth knowing about: their branding is not removable on the $29 Creator tier at all, only on a custom Pro deal.
So the honest placement of inDM in the table above is no longer "a small free allowance with an escape hatch." It is unlimited free sending with no meter behind it, priced against the cheapest published removal price in the set.
Where free stops working
Every free tier on this page runs on the same official Instagram API, which means none of them can exceed the platform's own limits: 750 private replies per hour, a 24-hour messaging window, and no cold DMs to people who haven't engaged first. Those ceilings apply to the private reply mechanism itself and to the messaging window around it, so they are the same on every plan.
What free genuinely cannot survive is a post that outperforms. The allowance is sized for a normal month, the ceiling arrives mid-conversation, and the people who commented after it are the ones who never hear back. That is the moment worth planning for, and it is not an argument for paying now. It is an argument for knowing which number you'll hit and roughly when.
And "free" is the fastest-decaying fact on this page. Every figure here carries the date we read it. If you are reading this well after those dates, open the pricing pages before you decide, including ours.
If free has stopped being enough, how much Instagram DM automation costs covers the same tools' paid plans, what each one meters, and what 10,000 delivered DMs works out to at each.
If you want the mechanism rather than the money, how Instagram DM automation works covers the two-message flow every tool here is built on, and what Instagram permits covers the rules all of them share.
And for ours specifically, what the inDM free plan runs sets out every automation type it includes, the one thing it asks in return, and the things paying changes.
