Build delightful internal tools in minutes with REST APIs

Connect any REST APIs in clicks, write queries and configure params + request body in the light-weight query editor, and bind data dynamically to a growing library of 45+ widgets from tables, charts, tabs, forms, a rich-text editor, and more. Give your end-users an easy interface to view and write records while preventing accidental data damage.

Deploy confidently to our cloud or self-host our on-prem open-source on Digital Ocean, AWS ECS, AWS AMI and more using our pre-built Docker and Kubernetes images.

What you can do with REST APIs + Appsmith

Present and view data with HTTPS methods: Use GET natively inside Appsmith to call any REST API and view the data as you like in widgets.
Write to REST: Use POST, PUT, DELETE and PATCH to write to any REST API that you connect to.
Import with cURL: Paste your cURL commands with APIs in one click and get a ready connection.
Bring other tools: Trigger actions to other datasources or SaaS tools from your app or stitch data together in the same UI.

Why Appsmith

Popular open source: Self-host the most popular open source app builder on the planet or deploy to our cloud. Get started in minutes on your Docker or Kubernetes clusters or choose one of our natively supported IaaS services.
Start quickly, deploy reliably: Start with our ready templates or fork them into existing builds. Manage multiple environments with ease and deploy fully functioning apps to production environments without breaking changes.
Only code when you want to: Drag-and-drop widgets to build your UI and bind data in seconds. Or go pro mode and write snippets or longer code anywhere in Appsmith, including on an in-built IDE for more complex CRUD actions.
