DoorMamba by GorillaDesk: what "free" really means
DoorMamba is the door-to-door app from GorillaDesk, the pest control and lawn care software. It is advertised as free forever. Here is what signing up involves, and how it compares.
Rep $30/mo, or $25/mo billed yearly · 14-day free trial · no contract
DoorMamba's website calls it "Door-to-Door sales software that's Totally Free!" and "The Only Free Forever D2D Sales App." Its Get Started and Login buttons open GorillaDesk's own sign-up and login pages, so a DoorMamba login is a GorillaDesk account, which starts as a 14-day trial. GorillaDesk plans are $49, $99 and $149 a month per route. DoorMamba is built "to seamlessly integrate with your GorillaDesk platform," and the jobs reps sell sync to the GorillaDesk calendar.
Signing up for DoorMamba created a GorillaDesk account with a 14-day trial. When the trial ended, we no longer had access to DoorMamba. So although it is advertised as "100% free" and "free forever", in our experience you need a paid GorillaDesk plan (from $49 a month per route on their pricing page) to keep using it, which is why we could not test it properly.

Questions people ask
What is DoorMamba?
DoorMamba is the door-to-door sales app made by GorillaDesk, the field-service software for pest control, lawn care and similar trades. It was released in December 2025 and is built to sync with GorillaDesk scheduling and billing.
Is DoorMamba free?
DoorMamba's site says it is "free forever" and both app stores list it as free. Signing up opens a GorillaDesk account, which starts as a 14-day trial; GorillaDesk plans are $49, $99 and $149 a month per route. When our trial ended, we lost access to DoorMamba, so in our experience it needs a paid GorillaDesk plan to keep using. Ask GorillaDesk in writing what you will pay before you start.
Do I need GorillaDesk to use DoorMamba?
Its sign-up and login buttons go to GorillaDesk's own sign-up and login pages, and the app is described as built to integrate with your GorillaDesk platform. FieldStacker works on its own, with door knocking, quotes, jobs and marketing in one app.
Does DoorMamba show homeowner names?
Not that we could find on its site or help pages. FieldStacker shows the owner's name, whether they own or rent, and an estimated age on plans with the owner reveal.
