Guest access forhotelsno subscriptions or hardware lock-in.

Remote check-in sets you free

GuestIn lets staff manage guest access in one mobile app while guests simply open a link.

No subscription. Pay only when a reservation uses GuestIn. If you open the door, you don't pay.

Staff download the app. Guests do not need one.

The problem

Most guest-access tools force the wrong tradeoff.

  • Some systems lock you into one hardware ecosystem.

  • Some add another monthly subscription before you ever use them.

  • Some guest flows are easy for staff but painful for guests.

  • Some tools are built for hardware first, hospitality second.

GuestIn is software-first, hospitality-first, integration-friendly, and fair on pricing.

01

Use supported devices, not a locked ecosystem

GuestIn already supports eWeLink and Shelly, and the integration layer is built to accept more providers over time. Flexibility, not vendor switching.

02

No subscription

There is no recurring platform fee just to keep the system available. Activate it, leave it on, run your hotel.

03

Maximum flexibility

Customize the guest access page with your property's branding — logo, colors and tone of voice — for a seamless experience.

How it works

From reservation to guest entry in a few steps.

The host workflow is app-based. The guest workflow is link-based. That split is one of the clearest usability advantages of GuestIn.

Pricing

Pay only when GuestIn is used.

No monthly subscription. You pay only when a reservation actually uses GuestIn. If the same reservation opens doors many times, you are still charged once.

One reservation

A guest checks in for a 3-night stay.

Many doors

Main entrance, room door and rooftop gate, used multiple times.

One charge

That stay counts as a single GuestIn usage.

From operators

Designed with hospitality teams in mind.

We didn’t want to change our whole hardware setup just to modernize guest access. GuestIn gave us a much simpler path.

The pricing finally makes sense. We pay when a stay actually uses it, not every month just to keep the software alive.
Owner, independent seaside hotel
“
Our staff uses the app, our guests just tap the link, and that’s exactly how it should work.
