big is pre-launch. The free tier is waiting when you are in.

the short answer

In three lines.

big suits
Creators whose audience is on Instagram and who want the automation, the link, the form and the contact list to be one product, with a contact record as the output rather than a message count.
ManyChat suits
Creators and social-first businesses who want to handle engagement at scale without being glued to their phone 24/7.source 2
the difference
One product in which the automation, the link, the form and the contact list hand off to each other, against a messaging suite whose output is the conversation.

side by side

What each one does.

big compared with ManyChat. Claims about ManyChat were checked 10 September 2026 and each cites its source below.
FeaturebigManyChat
Channels the tool sends onNo. big automates Instagram only. It does not send on WhatsApp, Facebook Messenger, Telegram, SMS or email.Yes. Instagram, Facebook Messenger, TikTok and Telegram on every tier; WhatsApp and SMS from Pro up; email metered at 10,000, 30,000 and 100,000 sends on Pro, Business and Advanced. Free and Essential connect up to 2 eligible channels, Pro up to 3, Business and Advanced all of them.source 3
Available to sign up for todayNo. big is pre-launch. Access is by waitlist, so a reader comparing the two today can try only one of them.Yes. The Free plan card shows "$0" beside a "Start for free" button. Sign-up is open today, with no waitlist.source 3
CLI and MCP access for an agentPartly. CLI and MCP access on tiny, big and bigger, not on teeny.Partly. API access is bundled with the Pro-and-above integration categories (Google Sheets, Zapier and Make; AI providers; CRM; SMS and email platforms; commerce; payments) rather than offered as a standalone developer surface. Free and Essential have none. No CLI or MCP surface is named on the page.source 3
Conditional branching inside one automationYes. big automations are built on a visual graph with branch nodes and conditional edges, so one automation can take different paths depending on what the person replies.Yes. A Condition block on the Flow Builder canvas can "guide your subscribed contacts down different paths based on specific criteria", beside the Message, Action, Data Collection, Randomizer, Start Automation and Smart Delay blocks. Absent on Free, present from Essential up.source 4
DM automation, forms and trackable links in one productYes. big runs Instagram DM automations, branching forms and trackable short links as one platform, and each hands off to the next: a comment becomes an auto-DM, the DM carries a tracked link, the link opens a form, the form fills a contact record.No. The product line is Instagram, WhatsApp, Messenger, TikTok and Manychat AI. There is no standalone form builder or link-shortener product; in-DM data collection is a block inside the automation, not a separate tool a comment can hand off to.source 5
Who owns the captured contact listYes. Contacts captured through big belong to the creator, not to big Followers belong to the platform; the contact list does not.Yes. The Terms of Service state that Manychat "does not claim any ownership rights" in User Generated Content, which is how they define the messages a Conversation Participant sends; for customers in the EEA, UK, Switzerland and Brazil, Section 8 adds that "you remain the controller of such customer data". Neither clause describes an export of the list.source 6
Sends through the official Instagram APIYes. big sends every reply and DM through the official Instagram API from Meta.Yes. The pricing page FAQ states ManyChat "works as a partner with TikTok and an Official Meta Business Partner". Instagram, Messenger and WhatsApp are Meta platforms.source 2
Instagram accounts per workspaceYes. 1 to 5 Instagram connections, depending on plan.Not stated publicly. The plan comparison counts channel types (up to 2, up to 3, or all eligible channels), not Instagram accounts per channel. No captured page states how many accounts one workspace can connect.source 3
Active automationsYes. 10 to unlimited active automations, depending on plan.Partly. Free: up to 4 active automations. Essential, Pro, Business and Advanced: unlimited custom automations.source 7
Automation volume includedYes. 100 to 100,000 automation steps per week, depending on plan.Yes. Metered on Active Contacts: a real person messaged during the monthly billing period, counted once however many times they are messaged. Included per month: Free 25, Essential 250, Pro 2,500, Business 7,500, Advanced 25,000, then a per-contact overage fee for the rest of that month. Not automation runs or steps.source 8
File storage for media used in repliesYes. 250 MiB to 100 GiB of file storage, depending on plan.Not stated publicly. No captured page states a limit on media stored for use in replies.source 3
History retainedYes. 7 to 90 days of history, depending on plan.Not stated publicly. No captured page states how long conversation or automation history is retained.source 3

who each is for

Pick the one that fits.

These are not close calls. If you are in the right-hand column, the other product is the better buy and we would rather you knew now.

Built for big

  • Creators running one Instagram account who would rather deepen what happens after the DM than add a second channel.
  • Creators who want the contact list they build to be exportable and theirs, rather than a follower count they rent from a platform.
  • Creators whose reply has to change depending on what the person actually answered, in the automation and in the form that follows it.
  • Teams that want an agent or a script to read and change the workspace directly, on a paid plan, through the CLI and the MCP server.

Better served by ManyChat

  • Creators who want to manage messages across Instagram, WhatsApp, Messenger, TikTok, Telegram, email and SMS from one place, rather than one channel.source 2
  • Creators who want to drive clicks and sales directly from messages, without a separate link or form tool.source 2
  • Teams who want AI-powered replies and broadcasts handling FAQs and lead qualification at scale, with priority support on the Business/Advanced tiers.source 2source 9

the real difference

Where the two part ways.

big is machines that hand off: a comment becomes a DM, the DM carries a tracked link, the link opens a form, the form fills a contact you own.

One trail from the comment to the contact

With ManyChat
ManyChat has no standalone form or link-shortener product: its product line is Instagram, WhatsApp, Messenger, TikTok and Manychat AI. "Data Collection" is one block inside a DM automation itself ("Collect emails, phone numbers, and text responses directly in DMs"), not a separate hosted form or tracked link a comment can hand off to. There is no ManyChat page describing a trail from a specific post or comment through a link click to a form answer as one traceable record.source 5source 10source 3
With big
In big the four machines are one product and each hands off to the next: a comment on a post starts an auto-DM, the DM carries a short link big minted and tracks, the link opens a form big renders, and the form's answers land on a contact record in the same workspace. Nothing is exported between steps, so the question of which post produced which contact is a lookup rather than a reconciliation.
Best for
Creators who want to know which post produced which contact without moving a CSV between two products.

The contact list is the output, and it belongs to the creator

With ManyChat
ManyChat's DPA frames a contact record as something it acts on at the Customer's (or a Data Subject's) instruction, not something it independently maintains: if ManyChat itself receives a request from a Data Subject to unsubscribe or delete their data, §7.2 states "Customer authorizes and instructs Manychat to unsubscribe or delete Content Data related to such Data Subject" rather than ManyChat acting on its own. §8.1 requires ManyChat to delete or return all Customer Content upon request following termination, subject to legal retention requirements. Neither clause describes an export format or a self-serve download of the contact list; both describe deletion and return as an obligation ManyChat fulfills on request.source 11
With big
What a big workspace accumulates is a contact list: the identity a person gave to a form, the tags applied to them, the links they clicked. It belongs to the creator rather than to big, which matters because the follower count on the other side of the automation never did.
Best for
Creators building an audience they intend to reach again when a platform changes its rules.

The automation branches, and so does the form after it

With ManyChat
ManyChat's own build guide shows the Condition block as one node type on a single Flow Builder canvas, alongside Message, Action, Data Collection, Randomizer, Start Automation and Smart Delay blocks: "guide your subscribed contacts down different paths based on specific criteria" by choosing a condition and defining outcomes for contacts who meet or don't meet it.source 4
With big
A big automation is a graph with branch nodes and conditional edges, and the form it hands off to is a sequence of pages with fork rules of its own, so the path one person takes can change twice: once on what they replied in the DM, and again on what they answered in the form.
Best for
Creators whose follow-up depends on the answer, in the conversation and in the form that follows it.

choose ManyChat if

Where ManyChat is the right answer.

These are things big does not do. If one of them is the job you are hiring a tool for, stop here and buy theirs.

Six ways in, not two

What they do
ManyChat's help center documents six distinct Instagram entry points beyond a post comment or a DM: a story reply or reaction, a story mention, a trackable ref-URL link, a click on a Meta Ads Manager ad, a default-reply catch-all for anything unmatched, and post or reel comments scoped per post, across all posts, or to the next post published. Each is documented as a separate mechanic with its own configuration: delay timers, once-per-user-per-window limits, and Highlight persistence for stories past 24 hours.source 12source 13source 14source 15source 16source 17
Where big stands
big starts an automation from two Instagram events: a comment on a connected post, and a direct message. There is no story reply, story mention, new follower, live comment or ad click entry point, and the graph has four node types, so a creator whose best-performing entry point is a story or an ad is comparing a narrower surface, not a cheaper one.
Best for
Creators whose audience arrives through story replies, new follows, live comments or paid ads rather than through post comments and DMs.

Five products, one account

What they do
ManyChat's own product navigation names Instagram, WhatsApp, Messenger, TikTok and Manychat AI as five separate products, each with its own page and positioning line, rather than channel settings inside one product. The pricing page FAQ names three more channels the navigation does not surface, Telegram, email and SMS, for seven in total.source 5source 2
Where big stands
big automates Instagram only. It does not send on WhatsApp, Facebook Messenger, Telegram, SMS or email, so a creator who needs one automation to reach the same person on a second messaging channel needs a second tool, and big is not that tool.
Best for
Creators whose audience answers on more than one messaging channel, or who run support in a shared inbox spanning several of them.

You can run it this week

What they do
The Free plan card shows "$0" beside a "Start for free" button, the pricing FAQ states that no credit card is needed on Free, and Essential and Pro can be trialed free for 14 days.source 3source 2
Where big stands
big is pre-launch and access is by waitlist, so anyone comparing the two today can only actually run one of them. Nothing on this page is a user count, a rating or a case study, because big has none to report.
Best for
Anyone who has to ship an automation this week.

questions

Questions about big and ManyChat.

Which Instagram events can start a big automation?

Two: a comment on a post you have connected, and a direct message. Both can match on keywords, and a DM automation with no keywords is a catch-all that fires on any DM. There is no story reply, new follower or ad click trigger.

Does big send on channels other than Instagram?

big automates Instagram only. It does not send on WhatsApp, Facebook Messenger, Telegram, SMS or email.

Does big need my Instagram password?

big sends every reply and DM through the official Instagram API from Meta. big never asks for an Instagram password and never operates a bot that pretends to be the creator. There is no scraping and no browser automation.

Who owns the contacts collected through a big form?

Contacts captured through big belong to the creator, not to big Followers belong to the platform; the contact list does not.

What does big count against a plan?

Automation steps per week, counted over the ISO week starting Monday at 00:00 UTC. Form submissions count against the same weekly budget. It is not a per-contact charge, so the bill does not grow with the size of your audience.

Can I use big today?

big is pre-launch. Access is by waitlist, so a reader comparing the two today can try only one of them.
