Choosing well
Check Android and desktop coverage
Confirm that the service has an Android app with the features your team needs on a Xiaomi, Redmi or POCO phone. Then match its web, Windows, macOS, iOS or Linux support to your other devices.
Platform coverage can differ between tools, so check the listed apps and browser access before switching.
Compare free plans, trials and paid prices
A free plan can help you start without a subscription, while a free trial gives a limited evaluation period. Check what is included before inviting a team.
Paid pricing may be quoted per user or as an annual amount. Compare the stated starting price and ask for a quote when pricing is on request.
Review access and retention controls
Guest access can let outside participants join selected conversations. Single sign-on can fit an organisation's existing login process.
Retention controls matter when your team must manage how long messages remain available. Check these settings alongside the service's message-history details.
Check history and group size
Message-history coverage affects how far back people can search or read conversations. Group-size limits affect whether a tool fits a team, project or larger meeting.
Compare these fields directly, since a service that suits small groups may not match a broad company chat.
Consider open-source code
Open-source code is available from tools in this category. If you need to read or change the code, check the project's licence, deployment terms and update activity before choosing.
