The pricing difference is structural, not cosmetic
ManyChat's Free plan caps at 25 contacts. After that, you pay per contact stored — the more your audience grows, the more you owe. Users on Reddit have documented bills jumping from $15 to $300+ after a single viral post, because every commenter who got a DM became a billable contact. The per-contact model was reasonable when comment-to-DM was a niche tactic. Now that it's table stakes for Instagram creators, it's a liability. Mastak charges a flat monthly rate. Your Starter is $12/month whether you get 10 DMs a day or 3,000.
One price. No overage math.ManyChat has an AI step. Mastak has an AI salesperson.
ManyChat's AI is a node you add to a flow — it handles a turn in the conversation, then exits. Context doesn't carry over between sessions. It also requires a paid plan plus a bring-your-own API key to unlock, making the effective cost significantly higher than the plan price. Mastak's AI runs the entire conversation: it remembers what each lead said in previous sessions, moves them through a qualification → value → objection → close sequence, and knows when to hand off to a human. No key required — it's included in the flat rate.
AI that remembers. Included.Flow builder vs. plain-text setup
ManyChat uses a visual node canvas — drag blocks, draw connections, configure each branch. Experienced users can build complex flows in it. Mastak takes a different approach: you describe your product and sales goal in plain text, pick a playbook, and the AI handles the rest conversationally. There is no canvas to maintain. When your offer changes, you update a text field, not a 15-node diagram.
Update once. Not fifteen nodes.Both use the official Meta API
ManyChat uses Meta's official Graph API — same as Mastak. Neither uses scraping or unofficial access methods. Where they differ: ManyChat went through Meta's App Review years ago and has a large install base. Mastak is going through App Review now, with Instagram in developer mode during the period before approval (Telegram works immediately). If you need Instagram automation live today and can't wait for App Review, that's an honest reason to start with ManyChat and migrate later.
