AppSmith

Appsmith is an open-source, low-code platform designed for developers to build custom internal tools, dashboards, and admin panels with remarkable speed. It allows you to move from idea to application much faster by providing a visual, drag-and-drop interface for building UIs, while still offering the flexibility to write custom logic and data transformations using JavaScript.

Connect to virtually any data source, including databases, REST/GraphQL APIs, and even Large Language Models (LLMs) to create powerful, data-driven applications. Key features include:

• Visual UI Builder: Assemble responsive interfaces with a library of pre-built widgets.
• Extensive Connectivity: Native integrations for PostgreSQL, MongoDB, Google Sheets, and any API.
• Full Code Control: Customize every aspect with JavaScript and import your own libraries.
• Git-Based Version Control: Collaborate with your team and manage deployments with Git.
• Enterprise-Ready: Deploy on your own infrastructure with options for air-gapped environments, SSO, and role-based access controls.

As a true open-source platform under the Apache 2.0 license, it offers transparency and eliminates vendor lock-in, making it a secure and scalable choice for businesses.
