heyy.to vs ManyChat (2026): Flat Pricing vs Per-Contact Billing

We make heyy.to, so read this knowing that. We are not going to pretend ManyChat is bad, because it isn't. It's the most capable Instagram automation platform on the market, and for a specific kind of user it's the right call. But it's built for a different job than heyy.to, and the biggest difference, the one that decides this for most people, is how you get billed.

ManyChat charges by contacts. heyy.to charges a flat monthly price. That one line explains almost everything else about who each tool is for.

Here's the full picture, including the parts where ManyChat wins.

The short answer

• Pick ManyChat if you're a marketing team that needs deep multi-step chatbot flows across Instagram, Messenger, WhatsApp, SMS and more, and you're fine with a bill that grows as your audience does.
• Pick heyy.to if you're a creator or small business who mainly wants comment-to-DM on Instagram, done safely, at a price that stays the same whether your reel gets 100 comments or 100,000.

If you already know per-contact billing is your problem, skip to the pricing section. If you're comparing the whole category, start with the best Instagram DM automation tools.

Side by side

	ManyChat	heyy.to
Pricing model	Per-contact (grows with your audience)	Flat monthly, never per-contact
Channels	Instagram, Messenger, WhatsApp, SMS, more	Instagram (comment-to-DM + link-in-bio)
Core strength	Deep multi-channel chatbot flows	Comment-to-DM + bio in one funnel
Official Instagram API	Yes	Yes
Rate limiting on viral posts	Yes	Yes, per-account caps
Kill switch	Account controls	Yes, instant stop
Link-in-bio built in	No	Yes, commission-free
Hindi / Marathi keyword matching	Limited	Yes
Best for	Agencies, multi-channel marketers	Creators, solo businesses, SMBs

Both tools use the official Instagram API, and both pace sends so a viral post doesn't blow past Instagram's limits. On the safety fundamentals they're level. Where they split is price, focus, and what they were built to do.

Pricing: the real difference

This is the section that matters, so let's be concrete.

ManyChat prices by contacts. A contact is a unique person who has interacted with your automation. The more people who comment your keyword or message your account, the more contacts you accumulate, and the higher your bill climbs. The logic is reasonable on paper: more contacts means more value. The problem shows up in practice.

Say you post a reel that does what you want it to do and goes viral. Twenty thousand people comment your keyword. That's a great day. Every one of those people becomes a contact. Next month, your ManyChat bill reflects all twenty thousand, whether or not any of them ever message you again. You did the hard part, you made something that worked, and the pricing model treats that success as a reason to charge you more. We wrote a whole post on why that stings: the per-contact pricing problem.

heyy.to prices flat. One monthly price, full stop. A free tier to start, and a single flat Pro plan (₹99 a month, roughly a couple of dollars) with no per-contact billing, ever. Your bill is the same on a quiet month and on the month your reel hits a million views. You are never taxed on your best content.

The trade-off is real and worth saying plainly: flat-priced tools are usually more focused. heyy.to does not have SMS, email sequences, or a fifty-node flow builder. It does Instagram comment-to-DM, story-reply, DM keyword auto-reply, and a link-in-bio page, and it does them well. If you need the multi-channel suite, ManyChat's pricing model is the cost of that breadth, and it may be worth it to you. If you don't, you're paying a growing bill for capacity you'll never use.

What it looks like as you grow

Model your cost at 10x your current audience, not today's. That's the honest way to compare.

• Small and staying small: the difference is minor. Both are cheap at low volume.
• Growing steadily: the per-contact line creeps up every month. Flat stays flat.
• One viral moment: per-contact can jump hard in a single billing cycle. Flat doesn't move.

If you expect to grow, and most people using these tools do, flat pricing is the more predictable choice by a wide margin. If you're a large operation that already has the audience and needs the flow depth, ManyChat's model can pencil out.

Where ManyChat is genuinely better

We're not going to pretend otherwise.

• Multi-channel. ManyChat runs Instagram, Messenger, WhatsApp and SMS from one place. heyy.to is Instagram-only. If your audience lives across channels, that's a real advantage.
• Flow depth. ManyChat's flow builder is deep: branching logic, conditions, delays, integrations, a big template library. If you're building genuinely complex conversational funnels, it's more powerful.
• Ecosystem. More integrations, more tutorials, more agencies who know it. If you want to hire someone who already knows your tool, ManyChat is easier to staff around.

If those three things describe your needs, ManyChat is probably your tool, and that's fine. We'd rather you pick the right thing than switch to us and be underserved.

Where heyy.to wins

• Flat pricing that never punishes a viral post. Covered above. For creators, this is usually the deciding factor.
• Comment-to-DM plus link-in-bio in one funnel. heyy.to combines a link-in-bio page with DM automation. Someone lands on your bio, or comments your keyword, and both roads feed the same funnel. No other tool ties the two together like this. More on that in link-in-bio and DM automation together and the full link-in-bio guide.
• Commission-free bio. Your link-in-bio page links out to your own checkout. heyy.to never takes a cut of your sales, because heyy.to never touches your money.
• Safety-first defaults. Official API, per-account rate caps, and an instant kill switch, on by default, not buried in settings. See is Instagram automation safe.
• Hindi and Marathi keyword matching. If your audience comments in Hindi or Hinglish, heyy.to matches those keywords properly. Most tools are English-first.
• Simplicity. Fewer knobs. If you just want "comment keyword, get DM" without learning a flow builder, that's the default, not a feature you have to find.

One thing neither of us does: cold DMs

Worth being clear, because people ask. Neither ManyChat nor heyy.to will mass-message strangers or auto-DM every new follower. heyy.to deliberately does not build that, because it's the behaviour Instagram restricts accounts for. Every heyy.to trigger is reactive: someone comments, replies to your story, or messages you first, and then the automation fires. We explain the reasoning in why we don't auto-DM new followers. If a tool promises to cold-DM your way to sales, that's a red flag regardless of which tool it is.

How to switch from ManyChat to heyy.to

If you've decided per-contact pricing is the problem and you want to move:

1. Export your contacts and leads from ManyChat first. Your list is your asset. Get it out before you cancel anything.
2. Rebuild your key automations in heyy.to. The core mechanic (comment-to-DM) is the same, so this is quick. Point them at a low-stakes post first to test.
3. Connect heyy.to through the official Instagram login. No password sharing, ever.
4. Run a live campaign through heyy.to once before you cancel ManyChat, so nothing drops mid-flight.
5. Then cancel ManyChat. Not before.

Switching is mostly painless because you're not relearning the whole concept, just moving it to a tool that bills differently.

FAQ

Is heyy.to a full ManyChat replacement? For Instagram comment-to-DM, story-reply, and DM keyword automation, yes. For multi-channel flows across WhatsApp, Messenger and SMS, no. heyy.to is Instagram-focused on purpose.

Is heyy.to cheaper than ManyChat? It depends on your audience size. heyy.to is flat, so it's cheaper the moment your ManyChat contact count pushes you up a tier, and much cheaper after a viral post. At very low volume they're both inexpensive.

Do both use the official Instagram API? Yes. Both connect through Instagram's official login and messaging API, and neither asks for your password. That's the safe way, and it's non-negotiable. See official vs unofficial API.

Will switching tools get my account flagged? No. Connecting and disconnecting official-API tools is a normal action. What flags accounts is unofficial password-based bots, which neither of these is.

Can heyy.to do WhatsApp? No. If WhatsApp automation is core to your business, ManyChat or a commerce-focused tool like Spur fits better.

Does heyy.to track DM open rates? No. heyy.to tracks DMs as sent, not opened. Instagram's messaging API doesn't expose reliable read data, so we don't claim numbers we can't stand behind.
