The internal tools standard, priced for companies that have an engineering budget

Specification

CategoryInternal tools platform

The realistic tier is Business at EUR 46 per builder plus EUR 14 per internal user, because audit logging, permission controls, embedded apps and unlimited environments all start there. A reader anchored on about 10 EUR will be off by an order of magnitude.
Free tierYes

n/a means the axis does not apply to this tool. It builds internal software behind a login, a native store app or an API, so there are no public crawlable pages to test. The axis is left out of the overall rating and the remaining weights are renormalised, rather than the tool being scored down for something we did not test.

Every axis is scored from 0 to 5 stars. The percentage is that axis's published weight in the overall 4.1 rating.

Our assessment in one line

The most professionally engineered product in this index, and priced accordingly. Retool takes the top marks on integrations at 4.7 and reliability at 4.6 because it connects to real databases with real credentials, has genuine source control, and self-hosts properly: a full deployment inside your own VPC via Docker in about fifteen minutes, which is a stronger ownership story than any hosted builder here, including our top-ranked tool. It also imports React apps built elsewhere, from Lovable or Replit, by ZIP upload or GitHub sync, and it now promotes a hosted MCP server on its own homepage: "Build an app from your favorite AI coding agent and deploy it here within your governed Retool environment." The honest qualifier on that axis is that the MCP server exists while the Platform API is Enterprise only with no published per-call price. Two costs to plan for: per-user pricing gets expensive fast, and Agents are billed separately from AI credits at a rate the vendor does not publish, so agent-heavy usage cannot be costed from public information.
