# Zenith > Run the open source apps your business needs, without running them yourself. One bill, scaled to what you use, not your headcount. Zenith is a managed platform for open source business applications. It replaces the SaaS your business pays per seat for: CRM, marketing automation, team chat, video meetings, team docs, email and calendar, project tracking, and shared files. You log in and use the apps the same way you would Salesforce or Slack. Zenith runs the open source software behind them. A ten-person team replacing Salesforce, HubSpot, Slack, Zoom, Notion, Google Workspace, Atlassian Jira, and Dropbox Business pays roughly $4,361 per month on SaaS. The same stack on Zenith is roughly $184 per month, saving about $50,124 a year. Pricing is a simple markup on compute usage. Growing the team does not grow the bill. Zenith is for small business owners and growing teams who are paying per-seat SaaS and cannot migrate off, because the alternatives need someone to run, secure, and maintain them. Zenith removes that barrier. ## What Zenith replaces - Your CRM, in place of Salesforce or HubSpot. - Your marketing automation, in place of HubSpot Marketing. - Your team chat, in place of Slack. - Your video meetings, in place of Zoom. - Your team docs, in place of Notion. - Your email and calendar, in place of Google Workspace. - Your project tracker, in place of Atlassian Jira. - Your shared files, in place of Dropbox Business. Existing data, accounts, pages, channels, links, calendars, boards, files, and pipelines come with you. The team logs in the way they always did. ## How Zenith is priced A simple markup on compute usage. No per-seat fees. No tiered plans. A growing headcount does not increase the bill. ## For developers building open source business software Open source ships on Zenith. If you build a self-hostable application that replaces a paid SaaS category, Zenith runs it for businesses that would never run it themselves. We pay 70% of profits to the developers who built the open source apps on the platform.
