How to choose

Which platforms does it need to run on?

Choose a platform that lists the places your team works. Options on this board include web, Android, iOS, Windows, macOS and an API.

If staff switch between desktop and mobile devices, confirm that the same service supports those systems before signing up.

Does it offer API access?

Use the public API mark to find services that can connect with other software through a documented interface.

An API can matter when you need customer messages to move between this platform and tools your team already uses.

Can I try it without paying?

Check the free-plan and free-trial marks separately. A free plan can continue without payment, while a free trial gives temporary access to a paid service.

Drift is listed with a free pricing model. Help Scout and HubSpot Service Hub are listed as freemium, with a free option noted for HubSpot Service Hub.

Should I choose an open-source platform?

If you need to read or change the code, check the open-source mark and the licence before choosing.

Open-source status is separate from having an API or a free plan, so compare those marks for the way you plan to operate the service.
