Low-code tools
20 services
Low-code tools split into internal tool builders, which wire forms and tables to your databases and APIs, and app builders for customer-facing web or mobile apps. On internal tool builders the limit that bites is usually seats: ReTool and UI Bakery each allow 5 users on the free plan, and manubes allows 1. Open-source options such as Windmill, BudiBase and ToolJet avoid seat limits entirely when self-hosted, at the cost of running the server yourself.
