The Best Postiz Alternative for Instagram DMs
Postiz is an open-source social media scheduler. It publishes your posts, and it has no Instagram DM automation at all. FlowGent is the other half: it answers the comments, story replies and DMs your posts create. Most people who need both use them side by side.

Why People Look for a Postiz Alternative
No DM automation at all
Postiz has no Instagram DM, comment-to-DM or story-reply automation. Its "Post comments" feature schedules comments on your own posts, which is not the same as replying to followers. If you want followers to get a DM, Postiz can't do it.
No inbox to answer from
Postiz is built for publishing, so there is no DM inbox. When a follower writes back, you answer in the Instagram app or another tool. FlowGent has an inbox with human takeover, so you can step in when the AI agent or a flow reaches its limit.
The AI writes posts, not replies
Postiz includes an AI copilot and AI images and videos for creating content. None of it replies to people. FlowGent's AI agent (Hobby and up) answers open questions in DMs, trained on your website and documents.
Self-hosting means setup work
Postiz is open source, so self-hosting avoids the monthly fee. According to its FAQ you run your own server and pay for Meta, Instagram, Threads and YouTube app approvals. That suits developers. It is a lot of setup for someone who just wants DMs answered.

FlowGent vs Postiz Pricing
Postiz costs $29/mo to start and covers posting. FlowGent costs $19/mo to start and covers DMs. They don't replace each other, so the real comparison is what each one costs for its own job.
FlowGent
Pay per message, not per contact
- Unlimited contacts on all plans
- AI included (Hobby+), no add-on fees
- 7-day free trial
Postiz
No hosted free tier, 7-day trial on every plan, self-host option (monthly billing)
- No Instagram DM, comment-to-DM or story-reply automation
- No DM inbox, so it cannot respond to followers
- No hosted free tier; self-hosting needs your own server and paid Meta app approvals
AI-Powered Conversations vs Open-Source Scheduler
Postiz's AI is for making content: an AI copilot, AI images and AI video clipping. None of it answers a follower. That is a fair split of jobs, not a flaw, since Postiz is a scheduler. If you want AI to handle the replies, you need a DM tool alongside it. FlowGent's AI agent answers open questions in DMs, learns from your website and documents, understands voice notes and hands over to you from the inbox.
FlowGent AI approach
- Understands intent, not just keywords
- Answers follow-up questions from what you teach it
- Trained on your website and documents
- Replies in the language your follower writes in
- Hands off to a human when it should
Postiz approach
- Open source with a self-host option
- Schedules to about 30 channels, including blogs and chat platforms
- API, webhooks, MCP server and CLI for automation
- Clear monthly and yearly pricing
- No DM or comment-to-DM automation
- No hosted free tier

Frequently Asked Questions About Postiz Alternatives

How much does Postiz cost?
Postiz costs $29/month (Standard, 5 channels), $39/month (Team, 10 channels), $49/month (Pro, 30 channels) or $99/month (Ultimate, 100 channels) on monthly billing. Billed yearly, that is $23, $31, $39 and $79 per month. Every plan has a 7-day trial, and there is no hosted free tier. You can also self-host the open-source version on your own server. Prices checked on postiz.com in October 2026.
Does Postiz have Instagram comment-to-DM or DM automation?
No. Postiz is a scheduler and publishing tool. It has no comment-to-DM, story-reply, keyword trigger or DM inbox features. Its "Post comments" feature schedules comments on your own posts. For automated DMs on Instagram you need a separate tool such as FlowGent.
Can I use Postiz and FlowGent together?
Yes, and they don't overlap. Postiz schedules and publishes the post. FlowGent watches that post's comments and your story replies and sends the DMs. There is nothing to switch off in either tool. See our Instagram DM automation tool guide for how to choose.
Is FlowGent cheaper than Postiz?
To start, yes: FlowGent Starter is $19/month and Postiz Standard is $29/month. But they do different jobs, so it is not a swap. Postiz can be self-hosted, which FlowGent can't. FlowGent's AI agent starts on Hobby at $49/month. See the pricing page.
Does FlowGent schedule posts like Postiz?
No. FlowGent doesn't schedule or publish content, and it isn't open source or self-hostable. It handles Instagram DM conversations only. Keep Postiz for publishing and add FlowGent for the replies.
