The chat platform Slack, which is mostly used by companies, is increasing its monthly price and changing the terms of its free plan. This afternoon, the company wrote a blog post about it. It is written there that if you pay for the “Pro” plan per user per month, the price will increase from $8 to $8.75 per user per month. Next, if you pay for the yearly “Pro” plan, it will cost you $7.25 per user per month instead of $6.67. And last, if you have the free plan, they are changing how messages are saved and for how long. The free Slack was showing the most recent 10,000 messages and 5 GB uploads. But now, it will not depend on how much was sent but on how much time has passed.
