ChronicleSlack's paid plan has changed name once and price twice since 2014. Here is what the pricing page said at each point, from archived copies of slack.com/pricing.
The record
- February 2014. Two paid plans: Standard at $8 per user per month and Plus at $15.
- January 2015. Yearly billing appears. Standard drops to $6.67 per user per month when paid annually; Plus to $12.50.
- June 2021. Standard is renamed Pro. The yearly price stays at $6.67.
- December 2023. Pro on yearly billing rises to $7.25, the first increase in nine years.
- 2026. Pro is $8.75 per user per month billed monthly. Business+ is $18.
What it means
The monthly-billed price moved from $8 to $8.75 over twelve years, about 9%. The bigger shift is in what the free plan includes: message history went from 10,000 messages to the most recent 90 days.
Slack is also running 50% off for 3 months on Pro and Business+ right now ($4.38 and $9). See the Slack pricing page for current plans, or compare Slack with Notion.
