ReplyKaro is cheaper. Here is what that buys and what it does not.

A flat ₹99 a month against a meter that only moves when a model writes something new. Both run on Meta’s official API, both send comment-to-DM in about a second, and on price this is not close — so the honest question is what the difference actually is.

Checked ReplyKaro’s own site

We are going to lose the price argument on this page, so it is worth doing it first and doing it plainly.

Their pricing, from their own site

Read on 8 September 2026. A free forever tier with no credit card and setup described as thirty seconds. Starter at $3 a month, or ₹99 a month in India. Pro at $9 a month. Billing through UPI and Razorpay. Their own homepage positions them as India's number one Instagram AutoDM tool and the cheapest ManyChat alternative, and on the second claim they are almost certainly right.

The counters on their homepage that day read 5,266 creators, just over three million DMs sent, and a DM success rate of 96%.

Their feature list is longer than ours: comment-to-DM, DM automation, story reply automation, keyword triggers, a follow gate, a visual flow builder, broadcasts to subscribers, product mode, canvas mode, and fan loyalty rewards.

Ours, for contrast

No monthly plan. One credit is one AI-written reply. A reply sent from a template you wrote is free and unlimited, however many people it goes to, because a repeated question does not need a model. Nothing is metered per contact, per follower or per conversation.

Free tier: 100 credits, no card. Packs: ₹499 for 500 credits, ₹1,699 for 2,000, ₹4,499 for 6,000, billed in rupees through Razorpay.

₹99 a month, flat

Predictable and cheap. You pay the same in a quiet February as in the week a Reel travels. For an account whose replies are genuinely the same five sentences, this is the correct shape and the correct price.

Nothing until a model writes

Zero on everything templated, forever, at any volume. A cost that appears only where a person asked something your templates did not cover — which is also the only place a model adds anything.

The arithmetic only favours us in one situation: when most of your inbox is repetitive, so the templated share carries the volume for free, and the remainder is small enough that a few hundred credits lasts. If your inbox is mostly novel questions, ReplyKaro's flat plan will be cheaper and we would rather you knew that here than found it out in month three.

Where the two products actually differ

Not features. On features they are ahead. Two things.

The voice. We build a profile from replies you wrote yourself and draft against it, and when the model produces something ungrounded, or is unsure, or is simply slow, your own template goes out instead. The generated reply is the upgrade, not the default. That is the thing the credits buy, and if you do not want it, do not pay for it.

What happens when a reply should not go. Ten named checks run in a fixed order before every send, the first failure stops it, and the reason is recorded where you can read it. Across our production history that has meant 35 sends stopped by cooldown, 19 by the rate budget, 9 by duplicate delivery and 5 by burst — about 2.3% of sends refused on purpose.

We publish that number because the useful question to put to any tool in this category is what its refusal rate is. Zero is not a good answer.

Any tool here can send a message in under a second. The interesting part is what it does in the second before, when something is slightly wrong.

What is the same

Worth stating so the differences are readable. Both run on Meta's official Instagram API. Neither asks for your Instagram password. Neither can message somebody who has not messaged you, broadcast to your followers, or send after the window closes — seven days from a comment, twenty-four hours from a DM — because those are Meta's limits and they apply to every tool identically.

Both bill in rupees, which for a registered Indian business is worth more than it sounds: no forex markup on an international card, and a GST invoice your accountant can actually use. The arithmetic on that costs roughly ₹8,000 a year on a USD-billed foreign tool.

Who should pick which

Pick ReplyKaro if price is the deciding factor, if you want branching flows or a follow gate, if you need broadcasts to subscribers, or if your replies are genuinely the same handful of sentences and a model would add nothing. That is a large share of accounts and it is not a consolation prize.

Pick us if you want replies that read like you wrote them, and if you want to be able to ask afterwards why a specific reply did not go out and get a named answer. If neither of those is worth ₹400 a month to you, the honest recommendation on this page is the other product.

When ReplyKaro is the better answer

ReplyKaro is the better buy on price and on feature count, and it is not marginal. ₹99 a month against our ₹499 packs, a free forever tier with no card, and a feature list that includes a visual flow builder, a follow gate, broadcasts to subscribers, product mode and canvas mode — we have none of those five. If you want branching flows, or you want to gate a link behind a follow, or you simply want the cheapest working comment-to-DM in India, buy theirs.

Questions people ask

What does ReplyKaro cost?
Read from their own site on 8 September 2026: a free forever tier with no credit card, a Starter plan at $3 a month globally and ₹99 a month in India, and a Pro plan at $9 a month. They advertise UPI and Razorpay billing and describe themselves as the cheapest ManyChat alternative.
Is ReplyKaro safe to connect?
On the question that matters, they are the same shape as us. Their site states they run on the official Meta API as a Meta Tech Provider, with no browser bots and no password sharing. That is the line that separates safe tools from risky ones in this category, and they are on the right side of it.
Why is PostEngage more expensive?
Because we are selling a different thing. A flat plan sells you sending capacity. We sell the writing: replies from a template you wrote are free and unlimited forever, and a credit moves only when a model has to compose something new. If your inbox repeats, most of your volume costs nothing here and the comparison is not what the sticker prices suggest. If your inbox does not repeat, we are genuinely the pricier option.
Do both tools have a free plan?
Both do, and theirs is larger on volume. ReplyKaro advertises free forever with no card and roughly 1,000 DMs a month on one account. Ours is 100 AI replies with no card, with templated replies uncapped underneath — so ours does not stop working when the hundred are gone, it stops being clever.
What does PostEngage have that ReplyKaro does not?
Two things we can point at. A voice profile built from replies you actually wrote, so a generated reply reads like you rather than like a chatbot. And ten named checks before every send — kill switch, connection, takeover, window, dedupe, cooldown, quiet hours, rate budget, credits, content safety — where the first failure stops the send and the reason is written down for you to read afterwards.
Which should an Indian creator pick?
On price, theirs, clearly. Pick ours only if the replies sounding like you is worth the difference, or if you want to be able to ask afterwards why a specific reply did not go out. Those are the two things we would defend; the rest of the comparison favours them.
