ManyChat vs Chatfuel: which one, or neither, for a comment-to-DM campaign

Three tools, the rows that decide most comparisons. Real monthly prices only, never an annual rate relabelled as monthly.

ManyChat is built for a business that messages people on many channels from one place. One contact record follows a person across Instagram, Messenger, TikTok and Telegram, with WhatsApp, SMS and email joining from $39. Channels running at once are capped: 2 on the $0 and $17 tiers, 3 at $39, all from $99.

The AI suite from $39 covers intention recognition, AI-drafted replies and a knowledge base the bot answers from. The flow builder has conditions and A/B branches. ManyChat holds Meta Business Partner and TikTok partner status, both documented programme memberships rather than marketing claims.

Its integration list, from Google Sheets at $17 to Zapier, Make, HubSpot, Klaviyo, Mailchimp and Kit at $39, is the deepest of the three; check the exact action you need, since a listing does not say whether a contact is created or a record updated.

Chatfuel's meter is the opposite of ManyChat's. Contacts and messages are unlimited, static keyword replies and broadcasts are never counted, and the AI plan is a flat $69 a month with a free Light plan below it. Channels are Instagram, Facebook, WhatsApp and TikTok.

WhatsApp is the strongest case. Chatfuel's WhatsApp Business Solution Provider status makes it a first-class channel rather than an add-on unlocked at a higher tier, and the company also holds Official Meta Partner status.

The AI side has a catch. Replies draw on an undisclosed fair-use allowance, and crossing it pauses the bot until the allowance resets. Chatfuel documents bringing your own OpenAI key to bypass the cap; price that separate usage cost rather than treating it as unlimited service.

Both platforms above are built to do far more than answer a comment, and you pay for the breadth whether you use it or not. If the whole job is one comment turning into a reply, a DM and a lead, a tool shaped for exactly that is worth testing first.

The free plan carries one live campaign, 1,000 engagements a month, AI matching and email capture, plus a 30-day trial of the paid features with no card needed. Paid plans are flat: $9 for 25,000 engagements adds CSV export, phone capture and Mailchimp or Kit sync.

The $29 plan (3 accounts) carries 100,000 engagements and adds outbound webhooks and AI-written replies; the top plan covers 400,000 engagements with 10 accounts. AI matching runs on every plan at 100 to 2,000 checks a day.

Overflow queues. A comment beyond the monthly allowance waits and releases oldest-first once the next cycle opens or the plan is upgraded, on every plan including free. One honest limit: a queued request that outlives Instagram's messaging window expires instead of delivering, so a flat bill is not the same as instant delivery.

The follow check is API-verified through Instagram's own is_user_follow_business field, and optional: turning it on is a creator's own choice. Email and phone capture happen on the delivery page, and every answered comment is logged as its own lead. Meta App Review approved the app in August 2026.

The first number on either page is not what a monthly subscriber pays. Three things to line up before comparing:

• ManyChat shows $29 and $69 on the annual toggle; billed monthly those plans are $39 and $99. The full real ladder is $17, $39, $99 and $199.
• Chatfuel shows $49 on the annual toggle; billed monthly the AI plan is $69. Chatfuel Light is free.
• ReplyMagnet lists $0, $9, $29 and $79 as monthly prices, with a 30-day trial and no card needed.

Figures pulled from each vendor's own published pages: ManyChat on 13 September 2026, Chatfuel on 29 August 2026. Where a vendor's material does not state something, the table says so rather than reading silence as absence.

The decision rule:

• ManyChat if Instagram is one channel among several run from a single inbox, and the flow builder, AI suite and integration catalogue are things you will actually use. Accept active-contact billing and the overage math above as the price of that reach.
• Chatfuel if WhatsApp is central and the automation is mostly keyword-and-broadcast rather than AI-driven. Unlimited contacts and unmetered static actions suit that shape; the trade is the undisclosed AI allowance.
• ReplyMagnet if the whole job is one comment turned into a reply, a DM with the file, and a captured lead, at a flat price that never surprises you with a bill or a pause.

If ReplyMagnet is the pick, five steps in this order:

1. Keep the original ManyChat or Chatfuel automation saved. Connect the Instagram or Facebook account to ReplyMagnet and start the free plan; no card is needed.
2. Create a campaign with the same trigger keyword on the same post, attach the file or link, and turn on email capture if you want the address.
3. Test from another account: open the DM on a phone and submit a test email if capture is on.
4. Turn off the old automation for that keyword or post. If both are live, whichever replies first wins the comment and the other looks like a duplicate.
5. Launch, then compare completed deliveries and usable lead records before changing the wording or adding steps.

Whatever sits in ManyChat or Chatfuel today stays there; exporting from either is outside what we can speak to. On our side, answered comments become leads at once, exportable as a CSV from $9 a month.

Start free with one existing guide or catalogue, or read the separate ManyChat pricing breakdown if the bill is your main concern.
