Appsmith is an open-source low-code platform, founded in 2019 and based in San Francisco, purpose-built for creating internal tools like admin panels, dashboards, and workflow apps rather than customer-facing products.
It combines a drag-and-drop UI builder with the ability to write custom JavaScript, giving both non-developers and engineers a fast path to functional internal software.

Appsmith connects to databases, APIs, SaaS tools, and LLMs, supports Git-based version control and CI/CD, and offers AI-assisted development from natural-language prompts. Self-hosting options include standard and air-gapped deployments for regulated environments.
