A virtual whiteboard that makes diagrams feel hand-drawn — and that's the whole point.
Retool is a low-code platform that lets developers build internal tools — admin panels, ops dashboards, data editors, support queues — quickly by connecting directly to databases, REST APIs, GraphQL, and cloud services. It's the answer to "we need an internal tool to manage X and we can't spare a developer for 3 weeks."
Engineering and ops teams at growth-stage startups and enterprises. Typically: a developer builds the Retool app, then non-technical teammates (support, operations, finance) use it daily. It's specifically for internal use — Retool doesn't power customer-facing products.
Free tier: 5 users, limited features. Team plan at $10/user/mo. Business at $50/user/mo (includes self-hosting). Enterprise custom pricing.
Retool is the market leader in internal tooling for good reason. The breadth of connectors and the quality of the component library are unmatched. For teams that would otherwise build a bespoke React admin from scratch, Retool saves weeks. The cost is the main objection — weigh it against engineering time at your salary levels.
