ManyChat alternative
The best ManyChat alternative, and the most agentic
Comment to DM, keyword flows and follow to unlock, run by your AI assistant over MCP, with a post scheduler built in.
The short answer
Postkey is the best ManyChat alternative and the most agentic one: ChatGPT, Claude or your own agent can build your Instagram DM automations, answer DMs and schedule posts over MCP. It automates Instagram and Messenger DMs today, and one plan holds up to 15 accounts, where ManyChat bills each Instagram account separately.

Why people look for a ManyChat alternative
- Price per account: each Instagram account needs its own ManyChat account and its own bill. "You can create and manage multiple Manychat accounts, and each one is billed separately. Pricing is applied per account, not per user."
- Contacts: since March 2, 2026 ManyChat's plans are priced by Active Contacts, 250 on Essential, 2,500 on Pro, 7,500 on Business, 25,000 on Advanced, with a charge for each contact past that.
- No post scheduler: you need a second tool to plan and publish the posts your automations reply to.
- No official MCP server: AI assistants cannot build ManyChat automations for you.

Questions
Postkey. It matches ManyChat's DM automation, adds a post scheduler, and is the most agentic DM automation tool, with an MCP server your AI assistant runs it through, all in one plan for less than ManyChat.
Postkey has a Free plan with 25 contacts a month and 5 scheduled posts a week, and paid plans with a free trial.
Yes. Postkey connects through Meta's official sign-in and API, so it works inside Instagram's rules, including the 24-hour reply window.
Yes, but do not run the same keyword in both, or people get two DMs. Switch each automation over one at a time.
