Openblocks

Openblocks is an open-source low-code platform designed for building internal or customer-facing applications. It provides a visual UI builder with pre-built components, native integrations to various data sources and APIs, and supports JavaScript for custom logic. The platform also includes features for access control, audit logs, and flexible deployment options.

Openblocks explicitly positions itself as an 'Open Source Retool Alternative' and directly lists features that align with Retool's core offerings. It highlights a 'Visual UI builder with 50+ built-in components', 'Native connections to PostgreSQL, MongoDB, MySQL, Redis, Elasticsearch, REST API, SMTP, etc.', and 'JavaScript supported everywhere to transform data, control components, etc.'. It also mentions 'Role-based access control (RBAC)' and 'Audit logs'. For deployments, it lists Docker, AWS AMI, and DigitalOcean. While it doesn't explicitly state 'one-click deployments', the listed options suggest flexible deployment capabilities. The 'DIY app themes' feature also matches 'Custom Theming & Branding'.
