LobbyStack starts free and stays under your control

LobbyStack gives a business enough free voice time to test its greeting, knowledge, booking rules, urgent transfers, and call records with real scenarios. Spam and calls under 10 seconds do not consume the allowance.

Upfirst’s per-call model can favor a company with long intake conversations. LobbyStack’s minute model can cost less when callers ask brief questions. Ninety one-minute calls fit inside LobbyStack Starter at $30, while Upfirst lists 90 calls at $59.95.

Both products handle the common receptionist tasks. LobbyStack separates itself after the call math: the code is public, the managed cloud has a self-hosted exit, and a technical team can control its providers and infrastructure.

Upfirst is a strong hosted receptionist

Upfirst gives a small business a direct setup path. You configure the business, connect a phone number and calendar, then decide how calls transfer or end. Its public feature set covers many situations that buyers care about:

direct scheduling during the call
warm and waterfall transfers
in-call text messages
recordings, transcripts, and summaries
spam filtering and caller memory
more than 35 languages

That breadth makes Upfirst a credible choice for an owner who wants hosted software and does not want to manage infrastructure. Its annual plans also pool calls across the year, which can help a seasonal business.

LobbyStack should not pretend those strengths do not exist. The choice comes down to billing behavior and control.

Compare calls with minutes using your own phone log

Upfirst charges by handled call. Its public monthly plans list:

$24.95 for 30 calls
$59.95 for 90 calls
$159.95 for 300 calls
$299 for 600 calls

Public overage prices fall as the plan grows. A call can run for several minutes without consuming a second call credit, so this model can suit businesses with long intake conversations.

LobbyStack prices hosted usage by voice minute. The Free plan includes 30 minutes, Starter includes 150 minutes for $30 per month, and Pro includes 500 minutes for $100 per month. That model can suit businesses that receive many short calls, such as callers checking hours, service areas, or appointment availability.

Take one month of call history and calculate both units. Twenty long intake calls can favor a call allowance. Two hundred brief calls can favor minutes. A headline plan price cannot answer that for you.

LobbyStack gives technical teams an exit from the hosted box

Upfirst’s reviewed official pages describe a hosted service. They do not advertise public source code or a self-hosted deployment.

LobbyStack is open source. You can use the managed cloud, inspect the code, or run the stack in infrastructure you control. A self-hosted team can manage its own provider accounts, secrets, retention policies, upgrade timing, and integrations.

That control carries work. Someone must operate the deployment, monitor calls, manage backups, and test upgrades. Upfirst removes that burden. LobbyStack gives you the choice.

The distinction matters for agencies, regulated teams, and operators who expect custom workflows. A business that only needs a dependable hosted receptionist may never use source access. A team that wants to modify call logic or avoid a permanent platform dependency may value it from the first day.

A practical service-business example

Consider an HVAC company with 180 calls in a summer month. Many callers ask one question and book a visit in under two minutes. Others describe an equipment problem for six or seven minutes before requesting a technician.

The owner should test both systems with the same calls:

an after-hours no-cooling request
a caller outside the service area
a maintenance booking with two available technicians
a customer who asks for a person
a spam call and an immediate hang-up

The winning product is the one that applies the company’s rules, completes the booking, and hands urgent calls to the right person. The bill should be calculated from that same test set.

Choose Upfirst when

Upfirst makes sense when you want a hosted service with broad language support and a mature self-serve feature set. Its call-based allowance can also work well when calls tend to run long.

Choose LobbyStack when

Choose LobbyStack when you want a free real-call test, lower pricing for frequent short calls, public code, self-hosting, or provider control. Agencies and technical teams can adapt the receptionist instead of rebuilding it.

Verdict

LobbyStack offers the stronger default starting point: no monthly charge, the full receptionist workflow, and an ownership path Upfirst does not advertise. Upfirst can still fit long-call businesses that value its language coverage and per-call billing.
