Retool

Retool connects directly to your existing databases and APIs, then lets you drag and drop components to build admin panels, dashboards, and CRUD interfaces without writing frontend code. It supports PostgreSQL, MySQL, MongoDB, REST APIs, GraphQL, and 500+ integrations, making it practical for teams running on any tech stack.

Best for engineering teams and operations departments building internal tools quickly. Unlike traditional low-code platforms that try to replace developers, Retool targets builders who know SQL and JavaScript but want to skip boilerplate HTML and CSS. Companies use it to cut internal tool development from weeks to days, with full audit trails and access controls built in.
