Retool

Retool is one of the highest-signal internal-tools products to include because it remains the benchmark many teams compare against when they want to build business software faster without building every interface from scratch. Its value is not just low-code speed; it is the combination of data integrations, app building, workflows, permissions, mobile support, and now AI-adjacent surfaces under one platform. That makes it more of a platform buy than a simple drag-and-drop app builder.

Its pricing is also nuanced enough that it needs a proper editorial read. Retool differentiates builder users from internal users, which usually makes more economic sense than charging every seat equally. The pricing page shows Free at $0 for up to 5 users, Team at $10 per builder and $5 per internal user per month, Business at $50 per builder and $15 per internal user, and Enterprise custom. Workflow runs, agent hours, and external-user pricing add further cost dimensions. That means Retool can be very cost-effective or surprisingly expensive depending on usage shape, not just seat count.
