Is there a free Instagram auto comment bot?
Two very different products share that search term. One is free and supported; the other is free and can cost you the account.
It depends which job you mean. Free tools exist for automatically replying to comments on your own posts, and Tadlo's free plan does this through Meta's official Instagram API. Free bots that post comments on other people's posts break Instagram's terms and risk action against your account.

| What the tool does | Allowed? | Why |
|---|---|---|
| Replies to comments on your own posts | Yes | Meta's official Instagram API exposes comments on your own media for exactly this. |
| DMs somebody who commented your keyword | Yes | The comment is what opens the door; this is the API's intended use. |
| Posts comments on other accounts' posts | No | Automated activity aimed at accounts that are not yours is against Instagram's terms. |
| Bulk likes or follows to farm engagement | No | Same rule, and it is the pattern automated-behaviour detection looks for. |
| Anything needing your Instagram password | No | It is driving your session rather than using the API, so the account carries the risk. |
What can a free tool do on your own comments?
- Reply publicly to a comment that contains a keyword.
- Send the commenter a direct message with the link or code they asked for.
- Hide or filter comments that match words you do not want under your posts.
- Require a verified follow before the link is released.
All four are things Meta's API supports on media you own, and all four are on Tadlo's free plan. Comment-to-DM automation covers the reply and the DM; comments management covers the filtering.
Why avoid the other kind?
A tool that comments on strangers' posts has to act as you, which means a password or a logged-in session rather than an official authorisation. Instagram treats that as automated behaviour against accounts you do not own, and the consequences land on your account rather than on the tool.
The tell is the signup screen. An official integration sends you to Instagram to authorise it and never sees your password. If a free comment bot asks you to type your Instagram password into its own form, that is the whole answer.
A free trial is not a free plan. Several tools in this category describe a time-limited trial as free. Check whether the thing still works in week three.
How Tadlo does it
Through the official Instagram API only, so there is no password to hand over and nothing is scraped. The free plan includes comment-to-DM, story reply automation and the verified follow gate, with unlimited DMs and unlimited automations. Paid plans are on pricing, and the tool comparison shows how the free tiers differ.
More questions on this
Is using an Instagram comment bot safe?
It depends entirely on whose posts it touches. Automatically replying to comments on your own posts through the official API is a supported use. A bot that comments on other people's posts, or that needs your password, is operating outside the API and puts the account at risk of restrictions.
Can I auto-reply to comments on Instagram for free?
Yes. Tadlo's free plan replies to comments on your own posts and can DM the commenter, with unlimited DMs and unlimited automations and no card. Other tools offer this free too, though several cap how many messages a month you can send.
Will Instagram know an automated tool sent the reply?
Yes, and that is fine. An official API integration is identified as an app, which is how Meta intends third-party tools to work. What is not fine is a tool pretending to be you by using your login credentials.
Can a free comment bot grow my follower count?
Not by commenting on strangers' posts, which is the risky kind. What does work is releasing something people want only after a follow is confirmed, so growth comes from your own audience acting rather than from activity aimed at other accounts.
What about tools that promise unlimited comments and likes?
Treat the promise as the warning. Posting comments and likes at volume on accounts you do not own is the behaviour Instagram's automation rules exist to stop, whatever the tool charges or does not charge.
