Building Internal Tools with Appsmith: A Complete Guide
Build custom internal tools and dashboards with Appsmith — the open-source low-code platform you self-host with Docker.
What Is Appsmith?
Appsmith is an open-source low-code platform for building internal tools, dashboards, and admin panels. With 35k+ GitHub stars, it is the most popular self-hosted low-code platform available today. You build UIs with drag-and-drop widgets, connect them to any database or API, and deploy via Docker on your own infrastructure — all without writing frontend boilerplate.
Why Developers Love Appsmith
Appsmith takes a developer-first approach. Every widget property accepts JavaScript expressions, so you can transform data inline, build custom logic, and create complex workflows. The platform supports REST APIs, GraphQL, and 15+ databases natively including PostgreSQL, MySQL, MongoDB, Redis, and Elasticsearch.
Drag-and-Drop UI Builder
Choose from 40+ widgets — tables, forms, charts, maps, date pickers, file uploads, and more. Arrange them on a responsive canvas, bind them to data queries, and preview instantly. The result is a production-grade UI in minutes.
Self-Hosted with Docker
Deploying Appsmith is as simple as running a single Docker command. Your data never leaves your network, and you control authentication via OAuth 2.0, SAML, or your identity provider. Role-based access control lets you grant granular permissions per app or per data source.
Git-Based Version Control
Connect Appsmith apps to Git repositories for branching, merging, and deployment workflows. Treat your internal tools like code — review, test, and deploy with confidence.
Getting Started
docker pull appsmith/appsmith-ce:release
docker run -d --name appsmith -p 8080:8080 -v appsmith-data:/data appsmith/appsmith-ce:releaseOnce running, open http://localhost:8080, create your admin account, connect a data source, and build your first app. Appsmith's visual query editor lets you write SQL, REST queries, or GraphQL directly in the browser.
Use Cases
