Enterkey vs ButterflyMX
ButterflyMX is building-installed hardware sold to property managers. Enterkey is a renter's app for the buzzer you already have. Compare costs.
This is less a rivalry than a category difference. ButterflyMX is a video intercom platform that buildings install: new panels at the door, sold to owners and property managers. Enterkey is an app an individual renter sets up on the buzzer their building already has. If you're a renter who can't rewire the lobby, that difference is everything.
| ButterflyMX | Enterkey | |
|---|---|---|
| Who buys it | Building owners and property managers | Individual renters (your PM just updates one phone number) |
| Hardware | Video intercom panels installed at entrances (panels list around $4,000–$6,500 each, checked July 2026) | None: uses the existing buzzer |
| Cost model | Roughly $30–42 per unit per year billed to the building, plus hardware | $9.99/month or $69.99/year (about $5.83/month), with a 14-day free trial for new members |
| Video at the door | Yes | No: audio buzzer systems |
| Time to working | A building retrofit project | Typically a day (one directory change) |

Can a renter just get ButterflyMX?
Not individually. ButterflyMX is sold building-wide: the property invests in panels and pays per-unit software fees, and residents get the app once the building is equipped. It's a genuinely strong product for new construction and buildings ready to modernize the whole entrance.
Enterkey exists for everyone else: the renter in a building that isn't retrofitting anything this decade. If your buzzer can dial a phone number, you can have smart entry this week without asking your landlord to spend thousands. Here's how the setup works.
What are the alternatives to ButterflyMX?
The alternatives to ButterflyMX fall into two groups. Buildings replacing their entry hardware compare other video intercom platforms sold to owners and property managers. Renters who cannot change the lobby panel use a buzzer app on the intercom that is already there: Enterkey, Lowkey, Ringo and Protobuzz all work that way, each with different features and pricing.
We compare six options side by side, with what each costs and who it is for, in ButterflyMX alternatives. If you are still working out whether your building's panel can call a phone at all, start with the apartment buzzer guide.
