Retool has built internal tools on company data for years; its AI now generates those tools from a prompt. The distinguishing claim is that generated apps are scaffolded from the real schema, roles and permissions, and respect existing SSO, role-based access and data-level permissions by default⁠1Automate and speed up business processes with AIRetool.

Best for: Companies with existing databases and APIs that want governed internal apps built on live production data, by a few builders for many users.

Not the right fit for: Teams with no database or technical owner, or buyers who need SSO and self-hosting without an Enterprise contract.

What Retool builds

Retool's AI prompts full-stack apps on live production data in sources such as Postgres, Databricks and Salesforce⁠1Automate and speed up business processes with AIRetool. Alongside apps, it offers workflows and agents that combine language models, code and human steps⁠1Automate and speed up business processes with AIRetool. It can also import React apps built in Lovable or Replit⁠2Build internal software better, with AIRetool.

The model is a few builders serving many users. Pricing is set per builder and per internal user, with external users (clients or partners) tiered separately on the Business plan⁠3Retool Pricing: Find the plan that works for youRetool. Permissions scale with the plan: Free and Team have only fixed All Users and Admin groups, while Business adds custom groups, organisation and object roles and per-environment access to resources⁠4Permissions quickstartRetool Docs. SSO, SCIM, Git source control and self-hosting are Enterprise features; self-hosted deployments run as a Retool-managed single tenant on AWS or self-managed on Kubernetes⁠35Retool Pricing: Find the plan that works for youRetoolSelf-hosted deploymentsRetool Docs.

Its earlier AI assistant, Assist, is no longer available in the classic app builder for most instances, according to a changelog entry dated 30 September 2026⁠6Assist (changelog: conclusion of the public beta)Retool Docs · 30 Sep 2026. Buyers comparing older reviews should note the change.

Published evidence

• Komatsu. Retool reports that Komatsu built call-centre automation in four weeks, cut email handling time from over seven minutes to about three and projects more than 22,000 hours saved a year from a pilot. Vendor-reported.⁠8Komatsu built call center automation in RetoolRetool

Strengths and limits

Strengths

• Generated apps are scaffolded from the real schema, roles and permissions, which addresses the most common failure of AI-built apps.
• Connects to existing databases and APIs rather than creating a new data store.
• Business adds custom permission groups, object roles and audit logs; Enterprise adds SSO, SCIM, Git and self-hosting.
• Publishes named, quantified customer stories (vendor-reported), including Ramp and Komatsu.

Limits

• Free and Team plans have only fixed All Users and Admin groups; custom permissions need Business.
• SSO, Git source control and self-hosting require Enterprise.
• Agents are billed separately by the hour, beyond a monthly free allowance.
• Its earlier AI assistant, Assist, was withdrawn from the classic app builder in September 2026.

Choose another option if: Your data still lives in spreadsheets and nobody owns a database. Softr or OpenLazarus start closer to that point.

Pricing

Published in euros on the page we read: Team €9 per builder and €5 per internal user a month billed annually; Business €46 and €14. Enterprise on request.

Prices on Retool's page were shown in euros when we read it, which suggests the page is localised; buyers outside Europe should check the figures in their own currency.

Questions to ask Retool

• Which of our data sources can the AI generate against, and which permissions does a generated app inherit?
• Which plan do we need for custom permission groups and audit logs, and what does it cost for our number of builders and users?
• How are agent hours metered, and what would one agent running all day cost?
• What changes when we move from cloud to a self-hosted deployment?
