Searching for a free alternative to anything is really two questions wearing one coat. The first is whether you can start without a card. The second is whether the thing stays affordable on the day it starts working. Vendors answer the first one loudly on the pricing page and the second one in a footnote.
We run a free tier, so treat what follows as interested. The arithmetic is still the arithmetic.
Free ends in one of three ways
A contact cap. Free until N unique people have spoken to you. The number sounds fine until you notice it counts forever, not per month. One Reel that travels can spend a year of headroom over a weekend.
A feature gate. Everything works except the part you needed. One keyword instead of many. Comment replies only on the newest post. The reply goes out with the vendor's name attached to the bottom of it.
Volume you do not control. Free until a message count, and your audience decides that count, not you.
All three are legitimate ways to run a business. The problem is common to all three: the bill arrives at the exact moment the tool starts earning its keep, which is the worst possible week to be shopping for a replacement.
Per-contact and per-reply break in different places
Both models are defensible. They fail under different conditions, and knowing which condition applies to you decides this faster than any feature list.
Metered on contacts
Metered on replies sent
That last clause is the part most people skip. If a tool meters replies but charges for every reply, per-reply pricing is just per-contact pricing with extra steps. The split has to be real: the answers you have already written should cost nothing to send, forever, and you should only pay when something genuinely new gets written.
That is how ours works. Templated replies are unlimited and free. Credits come out only when the model writes something new. Most accounts discover that four questions cover the bulk of their inbox, and four answers on file means most of the volume is free volume.
What a free tier can honestly include
Enough to answer the only question worth answering in week one, which is whether the replies sound like you.
- One Instagram account connected through Meta's official consent flow. No password handed over, ever.
- Comment replies on your posts and Reels, keyword filtered or not.
- DM replies inside Instagram's 24 hour window.
- Enough volume to cover a normal posting week, so you watch it handle a real cycle instead of a demo.
Ours is 100 credits and no card. That is roughly a week for a small account. It is deliberately enough to find out whether the drafts read like you wrote them, and deliberately not enough to run a business on indefinitely. Credit packs start at ₹499 when you need more.
What no free tier can honestly include is unlimited volume. Every reply is an API call, and a generated one is tokens on top. A tool promising unlimited free sends is either about to change its pricing or is not going through the official API at all, and the second kind of free is the expensive kind.
A free plan you cannot leave is not a free plan. It is a deposit.
Five things to check on any free plan before you build on it
- 01
Find the metered unit
Contacts, conversations, messages and automations are four different things and vendors are not consistent about which they charge for. Read it twice.
- 02
Ask whether contacts expire
Some plans roll off inactive contacts after 90 days. Some never do. That single footnote changes your annual total by a multiple.
- 03
Find out what happens at the cap
Sending stops, or sending continues and an invoice follows. Both are honest. Only one is safe to discover in production during a launch.
- 04
Look for branding in the message
A promotional footer on every reply is the free plan price, and your audience pays it rather than you.
- 05
Check the exit
Your templates and your record of who said what should export. If there is no export, you are not on a free plan, you are on a hostage plan.
When ManyChat is still the right call, free tier or not
If you need WhatsApp, stop reading. We do not do WhatsApp and are not planning to. ManyChat does, along with Messenger and other surfaces we never touch, and it carries a far longer integration list than we do. Those are real advantages that no amount of restraint substitutes for.
Same if you need a complex branching flow builder with commerce integrations wired through it. A bigger product has spent years on that surface. We have not, and shipping a worse version of it would not help anyone.
The honest summary
Free is a way to find out whether a tool is any good, not a business model you should plan around. Use the free week for the hard question. Every tool in this category can send a message. The gap between them is whether the message is one you would have written, and whether the tool has the judgement to send nothing when it is not sure.
If cost is the whole reason you are here, the bill arithmetic is the more useful page. If you want the feature by feature version, the direct comparison names what we lose at as well as what we win at.
