Official Meta APIs
Instagram Graph and WhatsApp Cloud API. You log in with Meta. CommentLink never stores your Instagram password.
What is free
Free means we do not invoice you
CommentLink does not charge for the product today. There is no card to start, no trial clock, and no “free forever” asterisk that hides a 25-contact ceiling. Automations, contacts, Instagram DMs, follow-gates, flows, and the shared inbox are open.
Two costs can still show up, and hiding them would be the dishonest version of “free”:
- Meta Instagram rate limitsInstagram messaging is not billed per DM by Meta, but volume is throttled. A viral Reel queues in CommentLink rather than ignoring those limits.
- WhatsApp conversation feesIf you connect WhatsApp, Meta bills your WhatsApp Business account at their published rates. CommentLink does not resell or mark that up. Instagram-only users do not pay that fee.

Included
What you get without upgrading
Instagram automations
Comment-to-DM on posts and Reels, public comment replies, Story replies and mentions, keyword or catch-all triggers, follow-gates, upcoming posts.
Links and leads
Link delivery in DMs, email or phone capture before the file goes out, welcome openers, flows, templates, suggest-more follow-ups.
Inbox and WhatsApp
Shared Instagram + WhatsApp inbox, assignment, notes, WhatsApp template broadcasts. Meta bills WhatsApp conversation fees to your WABA.
Team
Invite people, departments, roles, audit log, multiple Instagram accounts and WhatsApp numbers in one workspace.
Send queue
When comments spike, messages are paced inside Meta's limits instead of failing the automation.
How it works
Same product as the paid-looking tools
Free here is not a lite comment bot. You connect Instagram, pick a post, set a keyword, and send a DM — the comment-to-DM path most people search for. You can add public auto replies, a follow gate, Story automation, and the rest of the inbox without hitting a paywall in CommentLink.
Who it is for
Shops, creators, and small teams on Instagram
This is a fit if you run an Instagram Creator or Business account, you already ask people to comment for the link, and you do not want a monthly DM budget. It is also a fit if WhatsApp is the second channel after Instagram, not a separate paid inbox.
It is the wrong free tool if you need SMS, email marketing, Facebook Messenger, or a large multi-channel flow ecosystem — those are not what CommentLink sells, free or otherwise.
You still need the Instagram account type Meta requires: Creator or Business, linked to a Facebook Page. That is true on every official-API tool. Setup is sign up, connect, pick a post, write the DM. The comment-to-DM page walks the workflow; this page is only the commercial part — what you pay CommentLink (nothing) and what you might pay Meta on WhatsApp.
