Retool price: $15 per user per month (Business plan, billed annually). Two seat types: Business $50/builder + $15/internal user per month, billed annually ($65/$18 monthly); Team $10/builder + $5/internal user. The per-seat figure shown is the internal-user rate. Corroborated; the vendor page did not render prices as text. Source: vendor pricing page, checked 2026-11-10. Vendor site: Retool site. Put your plan's price into the estimator below if it differs.
Self-hosting saves about $2,940 a year for 20 seats: SaaS $3,600 vs self-host $660 (server $144, backups $36, admin time $480). Break-even at about 4 seats at these numbers.
Functions differ: an open-source tool rarely matches every Retool feature. Self-hosting means you handle updates, backups and security. Sponsored plate: none yet. Advertise.
