Pumble

Pumble is a team communication and collaboration app for businesses, with public and private channels, direct messages, group chats, and threaded replies. Teams can exchange files, links, voice messages, and video messages, then search past conversations and files. Voice and video meetings include screen sharing, meeting links, and in-call messaging. Pumble runs on web, Windows, macOS, Linux, iOS, and Android. Its API is publicly available for creating private or public integrations, and API access is available on any subscription. The Free plan costs nothing and includes unlimited users, channels, and message history, with 10 GB of workspace storage and up to three apps and integrations, alongside Clockify and Plaky. Paid plans start at $2.49/user/mo (annual); paid features can be tried for seven days without a credit card. Higher plans add storage, integrations, meetings, recordings, guest users, analytics, and Enterprise security controls.
