Appsmith | Open-Source Low-Code Application Platform
Stop grappling with data, scouring for the perfect React library, and coding everything from scratch. Build custom software 10X faster with Appsmith.
Categories:
Appsmith is an open-source low-code platform that enables developers and teams to build admin panels, internal tools, dashboards, and custom applications quickly by connecting to databases, APIs, and SaaS tools.
🚀 Overview
Appsmith solves the problem of building custom internal tools and apps from scratch, which is time-consuming and expensive, by offering drag-and-drop UI building, 25+ data source integrations, and JavaScript extensibility to create production-ready apps 10x faster.
It's built for developers, IT teams, support agents, and businesses—from startups to enterprises—who need to automate workflows, create dashboards, AI apps, customer support tools, and extend SaaS like Salesforce.
The Appsmith team built it to provide a secure, self-hostable low-code platform with full developer control, Git integration, and enterprise features, used by companies like GSK and Block to save development hours and costs.
✨ Key Features
- Connect to 25+ databases (PostgreSQL, MongoDB, etc.), any REST/GraphQL API, SaaS tools, and LLMs for real-time data access and self-hosted security.
- Drag-and-drop 40+ responsive widgets to build UIs; create custom widgets with JS/HTML/CSS or natural language AI prompts (what it does and why it matters: rapid prototyping with pro customization).

- Git version control, CI/CD, branching, and collaboration for deployment and maintenance.
- Enterprise security: SAML/OIDC SSO, RBAC, SCIM, audit logs, air-gapped self-hosting, SOC 2 Type II. Optional: upcoming AI low-code enhancements and package management.
