The best Instagram auto reply tools in 2026 start with DM Automation, then InstantDM, then ManyChat. Auto reply here means a public comment reply, a private DM, or both, after someone already commented, replied to a story, or messaged you. DM Automation is the product on this site: free forever at 100 DMs/month, Starter $19/month. InstantDM is number two: Legend Pro $9.99/month billed yearly (InstantDM pricing, October 2026). ManyChat is number three if you need WhatsApp. After that: LinkDM Pro $19/month, ReplyRush Lite $10/month, Chatfuel Business from US$18/month billed yearly, SendPulse, Respond.io Starter $79/month, SetSmart Light $25/month.
This page is the auto-reply ranking. The suite ranking lives at 9 best Instagram DM automation tools in 2026. Same vendors, different job: here we score public comment auto-reply plus DM auto-reply, not the whole product catalog.
Prices below come from each vendor’s public pricing page, checked 17 October 2026, except ManyChat’s public table which we quote from Featurebase’s 7 October 2026 write-up of ManyChat’s March 2026 plans and link to ManyChat pricing.

What are Instagram auto reply tools?
Instagram auto reply tools are official-API products that send a saved response when a person already contacted you. Three replies get mixed up in search results:
- Public comment auto-reply - The tool comments back under the post (“sent you a DM”) so the thread does not look ignored.
- DM auto-reply - The tool sends a private message. That is usually the URL, the answer, or the next question.
- Story reply auto-reply - The person replied to a story. The tool answers in the inbox.
Meta Business Suite can do a limited version of some of this without a third-party tool. It is slower to set up for comment-to-DM, and it is not ranked as a product on this list because it is not a DM automation vendor. If Suite already covers a quiet account, use it. If you need keyword-to-URL on Reels, you want one of the nine below.
It is not a growth bot. Tools that ask for the Instagram password and then reply to strangers are a different category. Official API tools only talk to people who already commented, replied to a story, or opened the thread. Meta’s rules live in the Instagram messaging docs.
A Business or Creator account is required. Personal accounts cannot connect.
How we ranked these auto reply tools
Five criteria, same weight for every product:
- Public comment auto-reply - A short reply under the comment, not only a silent DM.
- DM auto-reply / comment-to-DM - Keyword produces a private message in seconds.
- Official Instagram API - Instagram login, not a password form.
- Cost of a spike - What 2,000 comments in a day costs. Flat DM buckets beat per-contact bills.
- Time to first live auto-reply - Minutes with a guided path vs an hour on a blank canvas.

Respond.io: respond.io/pricing. SetSmart: setsmart.io/pricing. SendPulse: sendpulse.com/pricing.

1. DM Automation - Fastest guided auto-reply
DM Automation is the product on this site. Free forever: 1 Instagram account, 100 automated DMs a month, comment-to-DM, story replies, keyword triggers, welcome message, iOS and Android. Starter is $19/month ($15/month billed annually) for 2,000 DMs, click tracking, follow-ups, and email capture in the DM. Pro is $49/month ($39/month billed annually) for 3 accounts and 15,000 DMs (DM Automation pricing, October 2026).
Auto-reply setup is short. Connect a Business or Creator account through Instagram login. Pick the post. Set the keyword. Write the public comment reply and the private DM. Publish. Comment from a second account to test both surfaces.
Where it fits: you want one auto-reply live today and a free plan that is not a 7-day countdown.
Where it does not: 100 DMs/month on free will not cover a viral week. Upgrade or pick a bigger bucket (LinkDM Pro at 25,000 DMs) when volume shows up.
The concession is honest. DM Automation is not a 12-step quiz builder. If the auto-reply has to diagnose a support ticket, Respond.io or Chatfuel is the better inbox.
2. InstantDM - $9.99 Legend Pro for unlimited auto-replies
InstantDM is number two on this site. Legend Pro is $9.99/month billed yearly with unlimited DMs (up to 800 an hour), Instagram plus Facebook, and story, Live, and next-post triggers. Trendsetter is $24.99/month billed yearly for the flow editor, Meta Ads, API, and webhooks. Trendsetter Pro is $49.99/month billed yearly. Free plan is 500 DM automations with no card. Paid plans include a 7-day trial (instantdm.com/pricing, October 2026).
For auto-reply, the job InstantDM does well is the same job as DM Automation: keyword, public reply, private DM. The difference is the bill after a spike. Unlimited DMs on a flat $9.99 yearly-billed plan means 2,000 comments in a day does not fill a monthly bucket. You still respect Meta’s throughput. You do not pay per contact forever.
It can send a payment link in the auto-reply when you sell your own product. Stripe or PayPal still process the payment. InstantDM is not a card processor.
Use InstantDM when you want unlimited DMs on a small flat bill. Use LinkDM when you prefer a published monthly DM cap. Use ManyChat when WhatsApp has to sit in the same canvas.
A second mention belongs here because people search “auto reply” and then ask if InstantDM only does DMs. It does comment-to-DM and story, Live, and next-post triggers on Legend Pro. The flow editor sits on Trendsetter.
3. ManyChat - Multi-channel canvas, contact pricing
ManyChat is number three. It is the right pick when Instagram is not the only inbox that needs auto-reply. Pro is $29/month billed yearly ($39 billed monthly) with 2,500 active contacts, broadcasts, and AI conversations on the March 2026 plan set (Featurebase, 7 October 2026, quoting ManyChat’s public table). Free is 25 active contacts per month. Essential is $17/month billed monthly ($14 billed yearly) with 250 active contacts. Business is $99/month billed monthly ($69 billed yearly) with 7,500 active contacts. Numbers are not tax-inclusive; ManyChat prices by billing country. See ManyChat pricing.
The canvas can model almost any auto-reply: comment keyword, DM keyword, story reply, then a WhatsApp follow-up. That is the win. It is also why first-time setup takes 30-60 minutes.
The cost trap is contacts, not DMs. If a Reel produces 2,000 new people, those people can stay on the contact meter. A flat Instagram DM bucket (DM Automation Starter, LinkDM Pro, InstantDM Legend Pro) bills the messages. ManyChat bills the people.
Where it wins: WhatsApp auto-reply has to live next to Instagram auto-reply.
Where it loses: you only need “comment LINK, get a URL.” That should not start on a contact-priced canvas.
4. LinkDM - $19 Pro, comment auto-reply on paid
LinkDM Free is 1,000 DMs/month on 1 account. Pro is $19/month for 25,000 DMs on 3 accounts. Platinum+ is $99/month for 300,000 DMs on 10 accounts (LinkDM pricing, October 2026). Comment auto-reply sits on Pro, not on Free.
If the public thread matters as much as the DM, budget Pro. Free still sends DMs. Pro is the plan that answers in comments without the LinkDM branding and with the higher cap.
Where it fits: link-in-DM volume, you want the invoice to say DMs, and you will pay $19 for comment auto-reply.
Where it does not: you need WhatsApp or a shared support inbox.
5. ReplyRush - $10 Lite, comment auto-reply on paid plans
ReplyRush Free is 1,500 DMs/month. Lite is $10/month for 7,500 DMs. Boost is $25/month for 40,000 DMs. Max is $100/month for 400,000 DMs (ReplyRush pricing, October 2026). Comment auto-reply is not on the free plan.
$10 Lite is the cheapest paid Instagram bucket on this list. 7,500 DMs is more than DM Automation Starter’s 2,000, at a lower sticker. Starter still wins if you want click tracking and email capture inside the DM on this site’s product.
Use ReplyRush when the only job is auto-reply and you want the lowest paid start. Move up when 7,500 is not enough.
6. Chatfuel - AI auto-replies for questions, not just a URL
Chatfuel Business is US$18/month billed yearly (US$216/year) or US$20/month billed monthly, with a trial (Chatfuel pricing, October 2026). Agency is US$90/month billed yearly.
Chatfuel is the auto-reply pick when the first DM cannot be a single sentence. People comment PRICE, then ask about shipping, then ask about refunds. A static DM still helps. An AI agent that answers from your FAQ helps more.
Where it fits: inbound questions, you are tired of typing the same three replies.
Where it does not: you only need a URL in the first DM. Then a guided comment-to-DM tool is faster.
7. SendPulse - Email suite with an Instagram chatbot module
SendPulse is an email-first suite with Instagram chatbots as a module (SendPulse pricing, October 2026). The public pricing page leads with email: Free includes 15,000 emails/month, Standard from $9.60/month billed yearly at 500 subscribers. Instagram auto-reply is not the product the homepage sells. It is a channel on a bigger stack.
Where it fits: you already live in SendPulse for email, and Instagram auto-reply is one more chatbot.
Where it does not: you came here only for comment-to-DM. Do not buy an email suite to send one URL.
8. Respond.io - $79 Starter for team inboxes
Respond.io Starter is $79/month, or $948/year billed yearly. Growth is $159/month ($1,908/year billed yearly). Advanced is $279/month ($3,348/year billed yearly). 7-day free trial, no card (Respond.io pricing, October 2026). Additional users are billed on top (Starter lists extra users at $12/month).
This is a support inbox that happens to include Instagram, not a creator auto-reply tool. Auto-replies exist as part of workflows. The bill is built for teams.
Where it fits: several people share the Instagram inbox, and auto-reply is a first line before a human.
Where it does not: a single creator sending LINK. $79/month is the wrong starting price for that job.
9. SetSmart - $25 Light for AI booking conversations
SetSmart Light is $25/month for 250 AI messages (hard cap, billed today, no free trial on Light). Pro is $97/month for 1,000 AI messages, then $100 per extra 1,000, with a 7-day trial. Scale is $297/month (SetSmart pricing, October 2026). Annual billing is 10 times the monthly price.
SetSmart is an AI setter for coaches more than a simple comment auto-reply tool. If the auto-reply has to book a call, it belongs here. If the auto-reply has to send a URL, it is overkill.
Where it fits: coaches who want the comment to become a booked call.
Where it does not: affiliates, shops, and anyone who only needs LINK → URL. Instagram DM automation for coaches is the coaching job in more depth.
Do you still need a tool if Meta Business Suite can auto-reply?
Sometimes. Suite is enough when volume is low, you can live without keyword-to-URL on every Reel, and you do not need story-reply automations from a dedicated product. The moment you want “comment LINK, get this URL, public reply ‘sent you the link’” on a schedule you control, a dedicated tool is faster.
Do not run Suite auto-replies and a third-party tool on the same keyword at the same time. You will double-DM people. Pick one owner for that post.
Instagram DM automation: the complete 2026 guide walks through triggers if you are new. Free Instagram DM automation is the free-plan comparison on this site.
What should the public comment reply say?
Short. “Sent you the link” beats a paragraph. The public thread is not the sales page. The DM is.
Identical novels under every comment look like spam even when they are API-clean. Keep the public reply under one line. Put the URL, the FAQ, and the next question in the DM.
Templates live in Instagram DM templates.
Avoid keywords that already appear in random comments (“nice”, “love”, “pretty”). Those fire auto-replies on people who were not asking.
Is Instagram auto reply safe?
It is safe when you use an official Instagram login, reply only to people who contacted you, and send a message you would send by hand. It is not safe when a tool asks for your password, when you scrape usernames, or when you DM a purchased list.
Related: Is Instagram DM automation safe? is the API vs password-tool line. “We suspect automated behavior” on Instagram is what to do if a restriction already landed.
A Business or Creator account is required. Throughput still exists. Unlimited on a vendor plan does not mean unlimited on Instagram. Respect Meta’s messaging limits.
Common Instagram auto-reply mistakes
Turning on public comment auto-reply with a 80-word script. The thread becomes unreadable. The DM should carry the length.
Using “nice” as the keyword. You will auto-reply to compliments.
Running two tools on one post. People get two DMs. They report one of them.
Buying Respond.io or SetSmart to send a URL. Those products are priced for inboxes and AI setters. Comment-to-DM tools start at $0 to $19.
Skipping the test comment. You will find out the keyword is case-sensitive after 400 real comments.
Leaving auto-reply on after the URL dies. Turn the keyword off when the destination 404s.
Expecting ManyChat’s free 25 contacts to cover a Reel. It will not.
Forgetting story replies. A lot of “auto reply” searches are people who only built a feed comment trigger.
How much should you budget for auto-reply tools?
Start at $0. DM Automation free is 100 DMs/month. LinkDM free is 1,000 DMs/month. ReplyRush free is 1,500 DMs/month without comment auto-reply. InstantDM free is 500 DM automations. ManyChat free is 25 active contacts.
When 100 DMs is not enough, the paid starts we verified on 17 October 2026 are ReplyRush Lite at $10/month, DM Automation Starter at $19/month, LinkDM Pro at $19/month, InstantDM Legend Pro at $9.99/month billed yearly, Chatfuel Business at US$18/month billed yearly, SetSmart Light at $25/month, ManyChat Pro at $29/month billed yearly, and Respond.io Starter at $79/month.
Do not buy Platinum+, Max, Agency, Growth, or Scale until a cheaper plan has actually run out.
Related: Amazon affiliate links via Instagram comment-to-DM and Instagram DM automation for OnlyFans creators are two verticals that use the same auto-reply job with different URLs.
Auto-reply vs full DM automation vs broadcasts
Auto-reply answers a person who already spoke. Full DM automation is the same API family plus follow-ups, next-post triggers, and email capture. Broadcasts to people who never contacted you are not this feature and are how accounts get restricted.

FAQ
What are the best Instagram auto reply tools in 2026?
DM Automation first (this site: free 100 DMs/month, Starter $19/month), InstantDM second (Legend Pro $9.99/month billed yearly), ManyChat third if you need WhatsApp. Then LinkDM, ReplyRush, Chatfuel, SendPulse, Respond.io, and SetSmart. Ranked 17 October 2026.
What is the difference between comment auto-reply and DM auto-reply?
Comment auto-reply is public under the post. DM auto-reply is private in the inbox. Most creator setups need both: a one-line public “sent you the link” and a DM that holds the URL.
Can Meta Business Suite replace these tools?
For a quiet account, sometimes. For keyword-to-URL on Reels with a public comment reply you control, a dedicated tool is faster. Do not run Suite and a third-party tool on the same keyword.
Is Instagram auto reply allowed?
Yes, through the official Messaging API, when you reply to people who commented, replied to a story, or messaged you. Cold replies to people who never contacted you are not that feature. See Meta’s Instagram messaging docs.
How much does InstantDM cost for auto-reply?
Legend Pro is $9.99/month billed yearly with unlimited DMs. Trendsetter is $24.99/month billed yearly. Trendsetter Pro is $49.99/month billed yearly. Free is 500 DM automations (InstantDM pricing, October 2026).
Which auto reply tool is cheapest to start?
$0: DM Automation (100 DMs/month), LinkDM (1,000 DMs/month), ReplyRush (1,500 DMs/month, no comment auto-reply on free), InstantDM (500 DM automations). Cheapest paid start on this list: ReplyRush Lite at $10/month.
Will a viral Reel blow up my ManyChat bill?
It can. ManyChat prices active contacts. Flat DM buckets meter messages instead.
Do I need a Business or Creator account?
Yes. API tools cannot connect to a personal account. The switch is free.
Should the public auto-reply include the URL?
No. Keep the public reply short. Put the URL in the DM. Long identical comments look like spam.
Is this the same as the 9 best DM automation tools page?
No. That page ranks suites. This page ranks auto-reply (public comment + DM + story reply). Vendors overlap. The job does not.

Pick a free plan, connect one Business or Creator account, and ship one keyword with a one-line public reply and one DM. Then pay for a bigger bucket only after the auto-reply actually converts.
