Full Comparison
| Criterion | Betty Blocks | Retool |
|---|---|---|
| Starting price | From €1,500 / month Create plan. Scale is €3,500 / month and Custom is quoted. Builders and internal, external and anonymous app users are unlimited. | Free; paid plans from $10 / builder / month Annual billing: Team $10 per builder and $5 per internal user per month, Business $50 per builder and $15 per internal user. On monthly billing that becomes $12 / $7 and $65 / $18. Enterprise on request. |
| Free trial | Not stated | Free plan for up to 5 users |
| Output | Business applications, portals, workflow automations, AI agents and MCP servers | Internal web and mobile apps, workflows and AI agents |
| API | Yes, native, data and third-party APIs, and applications can be exposed to AI clients as MCP servers | Yes, the Retool API manages the organisation, its users and Spaces |
| Hosting | Public cloud, private cloud or on premises | Retool cloud or self-hosted |
| What you build | Business applications, client, employee and partner portals, workflow automations, AI agents and MCP servers, generated from prompts or built visually | Internal tools: web and mobile apps, scheduled and event-driven workflows, and AI agents; an AI app builder starts an app from a prompt next to the classic drag-and-drop editor |
| Stack and frameworks | A metadata-driven visual application model whose applications output React and WebAssembly; custom actions are uploaded as WebAssembly modules compiled from languages such as Rust, Go, Python, C#, JavaScript or TypeScript | Drag-and-drop component library with JavaScript in queries, bindings and transformers; custom components are written in React and TypeScript and published to the organisation's component library |
| Auth and database | Role-based access and single sign-on through ADFS | Connects to any database, API or LLM provider, with a hosted Retool Database included; permissions and audit logging from the Business tier, SSO and SCIM on Enterprise |
| Connectors | Native, data and third-party APIs, with direct connections to SAP, JD Edwards, Workday, Salesforce, Microsoft Dynamics and Exact; reusable integrations are built, stored and configured in the Block Store | Listed integrations for databases such as PostgreSQL, MySQL, MongoDB, Microsoft SQL Server, Snowflake and BigQuery, for AI providers, CRMs such as Salesforce and HubSpot, messaging and Stripe, plus generic REST, GraphQL, gRPC, SOAP, OpenAPI and JDBC connectors for anything else |
| Hosting and deploy | Public cloud, private cloud or on premises, chosen at purchase or migrated from public cloud later, with Kubernetes and Docker container support for single-tenant installations | Retool cloud or self-hosted; the free, Team and Business tiers can both be self-hosted, Enterprise adds unlimited end users and white-labelling |
| Governance and admin | Roles, environments and approvals before changes reach production, plus control over which data and actions are exposed to AI clients through MCP; ISO 27001 certified with a SOC 2 Type 2 report | Rich permission controls, audit logs and resource environment permissions from Business; Team gets staging and production environments, Business unlimited ones. SSO over SAML or OIDC, SCIM, enforced 2FA, Git source control, independent Spaces and usage analytics are Enterprise-only, and the platform APIs are limited on Business and fully open on Enterprise |
| Payments | Payment processing in the apps it builds, through PayPal, Mollie, Stripe or another payment gateway, for example to settle invoices in a vendor portal; a Stripe connection lets customers pay and view invoices in a customer portal | No built-in billing or checkout; a payment provider is connected as an API resource like any other |
| Access to the code | Customers own their applications, which export as standard React and WebAssembly | Apps live in Retool rather than as an exportable codebase; JavaScript and custom React components extend them, and Git-backed source control is an Enterprise feature |
| AI assistant | Betty Genius is the app generation engine and builds applications and interfaces from prompts, with guided prompting and automated validation; AI usage carries no extra charge, and the Custom plan adds a free choice of LLM | An AI agent in the app builder's Chat tab plans and builds React apps from natural-language prompts, with uploaded files as context and a choice of model per thread; functions that change data need approval while previewing and before publishing. Metered as AI credits, from 250 a month on Free to 3,000 on Business, and Enterprise can bring its own API keys |
| Pricing model | A flat monthly platform price in euros by app bundle size, Create €1,500 and Scale €3,500, with Custom quoted; builders and app users are not counted | Per seat, split by role: builders and internal users are billed separately, and external users on Business are free up to 50 and then priced in volume bands. Annual billing saves 20 percent against monthly, a free plan covers up to 5 users and Enterprise is quoted. Self-hosting uses the same seat prices, capped at 100 users on Team and Business |

- A developer sandbox and multiple MCP servers start with the €3,500 Scale plan

- Self-hosting is available on every tier, the free one included

How we check reviews
Reviews are not published yet. The form on a tool's page works and reaches us, but nothing from it appears on this site, so no score here is based on a review. The rules below are the ones that will apply once reviews go live.
Every review is read by a person before it appears. We require a working email address and use it to come back to the author, so a review has a reachable sender rather than being anonymous. We publish positive and negative reviews alike, we pay nothing and offer nothing for a review, and we accept none that was bought or incentivised.
What we cannot do is verify a purchase. There is no shop here and no account, so whether the author really used the tool rests on what they tell us, plus the plausibility of what they write. We say so rather than implying a check that does not exist.
A vendor cannot have a review removed, cannot buy one, and cannot have one changed. Paid placement and a paid listing have no effect on which reviews appear or on any score.
