Klang vs Slack
Slack is made for companies, and it’s very good at that. For a community, a gaming group or friends, Klang keeps your whole history for free, has voice channels for everyone and charges per server, not per person.

Built for different groups
Slack is the standard for work chat: channels, threads, hundreds of integrations and admin tools for companies. Its prices follow that: you pay for every active member, and the free plan only shows the last 90 days of messages.
Klang is built for people who talk, play and hang out together. Everyone uses it for free, history is never cut, and voice is a place you drop into, not a call you schedule.
Where Klang is ahead
- All your history, free. No 90-day window: last year’s plans are still there.
- Voice channels. Join a voice channel and whoever is there can hear you. Group calls of up to 10 people on the free plan, with screen sharing.
- You don’t pay per member. One person can upgrade a whole server for $4.99 or $11.99 a month.
- Guests. An invite link is enough to join and talk, even without an account.
Where Slack is ahead
- Integrations and workflows, from calendars to ticketing tools.
- Huddles of up to 50 people on paid plans, and files of up to 1 GB.
- Threads and enterprise tools like Slack Connect, retention policies and compliance.
The bottom line
For a company, Slack does things Klang doesn’t try to. For a community or a group of friends that’s tired of losing old messages or paying per head, Klang is free, keeps everything and has voice built in.
