How we calculate
For each paid tool you keep switched on, we take its public list price for the plan shown and multiply it by the seats your team would need. Some tools are only used by part of a team, so a row may count a share of your team or a fixed number of seats; the row says how many. Prices that depend on sales or usage are shown but not counted.
From that we subtract an estimate for running the open-source stack yourself: $165/month plus $2 per person per month (Two 8 vCPU / 16 GB cloud servers, plus storage per person), and any extra running cost a row lists, such as a GPU. The time it takes to set up and maintain the tools is not included.
