Stack
Tech stack of the templates
The languages, libraries, services, build tools, web servers and test tools the templates use, and what Light Cloud does with each when it deploys your app.
Free plan, no card. Google or GitHub sign-in.

Nothing to set up: Light Cloud builds the project with its runtime or its Dockerfile, and the build turns the code into what runs.
TypeScriptJavaScript with types, checked before the code runs.
JavaScriptThe language of the browser, and of Node.js on the server.
HTMLThe markup every web page is made of.
CSSThe language that styles web pages.
C#Microsoft’s typed language for .NET.
ClojureA functional Lisp that runs on the Java virtual machine.
HaskellA pure functional language with a strong type system.
Frameworks and libraries
Installed with the app's other dependencies when Light Cloud builds it, from the lockfile or the template's Dockerfile. Nothing to set up.
WaspA full-stack framework that generates a React front end and a Node.js server from one config.
Django REST frameworkThe toolkit for building REST APIs with Django.
EchoA fast, minimal web framework for Go.
SlimA micro framework for PHP APIs.
LaravelThe PHP framework for web apps, with an ORM, queues and auth built in.
Ruby on RailsThe Ruby framework for database-backed web apps.
React RouterRouting for React apps, from simple pages to full-stack loaders and actions.
RxJSReactive streams for JavaScript, used throughout Angular.
TanStack TableHeadless tables with sorting, filtering and paging.
discord.jsThe Node.js library for Discord bots.
htmxHTML attributes that fetch and swap page fragments without writing JavaScript.
ZodSchemas that validate data in TypeScript and give it types.
PydanticData validation for Python with type hints.
Better AuthSign-in for TypeScript apps: email and password, sessions, organisations.
UI and styling
Compiled into the app's HTML, CSS and JavaScript by its build script, which Light Cloud runs on every deploy. Nothing to set up.
Data and databases
Templates keep their data in a PostgreSQL database that Light Cloud creates and connects, with the connection string in an environment variable.
Drizzle ORMA TypeScript ORM with SQL-like queries and migrations.
PrismaA TypeScript ORM with a schema file, generated client and migrations.
SQLiteA small SQL database kept in a single file.
MySQLA widely used open-source SQL database.
GraphQLA query language for APIs: the client asks for exactly the fields it needs.
Services and APIs
Needs an account and keys of its own. They go in the app's environment variables on Light Cloud; the deploy form asks for the ones the template needs.
StripeOnline payments, subscriptions and invoices.
ResendAn API for sending email from your app.
ClaudeAnthropic’s AI models, used through its API.
OpenAIOpenAI’s models, used through its API.
Amazon S3Object storage for files, with an API many providers copy.
Telegram Bot APIThe HTTP API for Telegram bots.
Build tools and package managers
Runs inside the Light Cloud build, in the build container, so there is nothing to install or run yourself.
ViteA fast dev server and bundler for front-end projects.
npmThe package manager that comes with Node.js.
ComposerThe package manager for PHP.
MavenThe build tool and package manager for Java.
RubyGemsRuby’s package system, used through Bundler.
Alpine LinuxA tiny Linux distribution often used as a container base image.
Web servers
Runs inside the app's container and answers its requests; Light Cloud sends HTTPS traffic for the app's URL to the port the container listens on.
Testing and code quality
Runs on your machine or in CI. A Light Cloud build installs the dependencies and runs the build, never the tests or the linter, so run it before you push.
VitestA fast test runner for Vite and TypeScript projects.
JestA JavaScript test runner with mocks and snapshots built in.
Testing LibraryTests that use components the way people do.
pytestThe most used Python test framework.
JUnitThe standard test framework for Java.
go testGo’s built-in test tool.
ESLintThe linter that finds problems in JavaScript and TypeScript.
RuffA very fast Python linter and formatter.
Formats and specifications
Part of the files in the repository: change them and push, and Light Cloud builds and deploys the new version.
YAMLA readable format for data and settings.
JSONThe common format for data on the web.
MarkdownPlain text with light formatting, turned into HTML.
MDXMarkdown with React components inside.
NunjucksA templating language for HTML layouts.
OpenAPIThe standard description of an HTTP API, read by docs and client generators.
