Where you live on the web.$1/moHow the math works
Three traffic scales, three price points per option. Hobby targets a weekend-project budget (free where possible, $5-10 VPS otherwise). Side-project assumes paying customers around 5k monthly active users — where free tiers usually end and you pay for the cheapest credible paid tier. Scale targets ~50k MAU production workloads.
Payment processors (Stripe, Lemon Squeezy, Paddle, Polar) show as $0/mo because their fees are per-transaction, not subscription — see stripe-alternatives for the per-sale math that includes tax-compliance overhead.
Every price traces back to a public pricing page verified within the current month. When vendors change pricing, this calculator updates with the next commit. See methodology for the full pricing approach.
