Overview

Lowdefy is an open source, config first low code web stack for building internal tools, admin panels, CRUD interfaces, dashboards and business applications. You describe an application in a single declarative configuration file, its pages, a rich library of UI blocks, data connections and requests, and the logic that ties them together through an operator and event system, and Lowdefy compiles that configuration into a production web application. Because the whole application is reviewable, version controllable text rather than hand written frontend code, teams ship internal software quickly and consistently, and the same configuration is easy to generate, diff and audit.

Why the cloudimg image

Lowdefy has no built in login, so a bare deployment is a liability. cloudimg makes it secure by default: the application server binds to loopback only and is fronted by nginx with HTTP basic authentication, and on first boot every instance generates its own administrator password and its own application signing secret and writes them to a file only the root user can read, so no default credential is ever reachable and no two instances share one. The image is hardened and fully patched, serves the official Lowdefy starter application so a live low code server is usable the moment it boots, and is ready for your own configuration. Every instance ships with a paired deployment guide and 24/7 cloudimg support.

Common uses

  • Building internal tools and admin panels
  • CRUD interfaces and dashboards over your data
  • Config driven business applications for your team

Key features

  • Config-first low-code web stack: Lowdefy compiles a single YAML file into a production web application for internal tools, admin panels, dashboards and CRUD interfaces, pre-built and serving the official starter app behind an nginx reverse proxy on port 80 with no manual setup
  • Secure by default: no known bootstrap credential ships - the app binds to loopback only, and a unique administrator password and application signing secret are generated for every instance on first boot and stored in a root-only file
  • 24/7 technical support from cloudimg, with expert help on deployment, TLS termination, application configuration, connecting data sources and scaling

Description

This is a repackaged open source software product wherein additional charges apply for cloudimg support services.

## Why This AMI Instead of Self-Deploying?

Lowdefy is an open source, config-first low-code web stack for building internal tools, admin panels, CRUD interfaces, dashboards and business applications from a single declarative YAML configuration. You describe pages, blocks, data requests and logic in lowdefy.yaml and Lowdefy compiles it into a production web application. Deploying it yourself means installing Node.js and pnpm, installing the Lowdefy CLI, building the application into a production server, fronting it behind a reverse proxy, and adding authentication because Lowdefy ships no login of its own. This AMI eliminates that effort entirely: a live, usable low-code server is running within minutes of launch, serving the official starter application behind an nginx reverse proxy, with no manual package installation and no dependency troubleshooting.

The current release available is Lowdefy 5.5.0.

## Application Stack

The Lowdefy CLI compiles the configuration into a production Next.js server that binds to the loopback interface only. A host nginx reverse proxy fronts it on port 80 and adds HTTP Basic authentication, so the whole application is reached through one URL and no application port is exposed beyond loopback. Two systemd services manage the stack for automatic restarts and clean logging.

## Secure By Default

Many pre-built images ship with shared or default credentials - a common vulnerability that exposes instances immediately after launch. This image eliminates that risk entirely:

  • There is no known bootstrap credential: the application binds to loopback only and is fronted by nginx HTTP Basic authentication
  • A unique administrator password and a unique application signing secret are generated for every instance on its first boot and written to a root-only credentials file
  • No world-open window is ever exposed and no shared or default password ships in the image
  • nginx is ready for your TLS certificate and systemd manages the service

## Ready To Use

Browse to the instance on port 80, sign in with the generated administrator credentials, and the official Lowdefy starter application renders in your browser. To build your own application you edit /opt/lowdefy/lowdefy.yaml, rebuild with the Lowdefy CLI and restart the service. Lowdefy provides a rich block library, an operator and event system for logic, connections and requests to databases and APIs, theming, and optional authentication providers, all driven from reviewable configuration that is easy to version-control and generate.

## What You Avoid By Using This AMI

  • Installing Node.js, pnpm and the Lowdefy CLI and building the production server
  • Configuring nginx as a reverse proxy with authentication in front of the app
  • Generating and securely storing an application signing secret
  • Ongoing maintenance and security patching without expert guidance

## cloudimg Support

24/7 technical support by email and live chat with a one-hour average response for critical issues. Our engineers help with deployment, TLS termination, application configuration, connecting data sources and scaling.

## Use Cases

  • Building internal tools, admin panels and CRUD interfaces from reviewable YAML configuration
  • A private, in-your-own-VPC low-code platform for dashboards and business applications
  • Version-controlled, config-driven web apps that connect to your own databases and APIs
