# Website and API Hosting: Node.js, Python, Static Sites
> Website and API hosting behind Cloudflare: included squareweb.app subdomain, auto-renewing TLS, global CDN, WAF and custom domains on Standard and up.
## Why choose Square Cloud?
Every site is served from behind Cloudflare's global network, with free TLS, a free CDN and DDoS protection wired in by default: the same production-grade edge whether you deploy a static landing page or a full framework SSR app. You configure a subdomain; we handle certificates, caching and routing.
Every site sits behind the **Cloudflare WAF** with **Square Shield** on top: DDoS mitigation, bot filtering and free, auto-renewing TLS included at no extra cost.
**Enterprise NVMe SSDs** and **10Gbps** uplinks, with your app in an isolated container. Paired with a **free global CDN**, static assets are cached at the edge and served close to every visitor.
**Bring your own domain, certificate handled for you**: [attach a domain you already own](https://help.squarecloud.app/en-us/article/how-to-set-up-your-own-domain-cnamedns-1fzbrgh/) (Standard and up), create the DNS records the dashboard shows at your DNS provider, and Square Cloud issues and renews the TLS certificate as soon as they propagate.
**One-click restore points**, included at no extra cost. Recover from a broken deploy in seconds with no data loss and **zero downtime**.
## Supported environments
Host your site with the stack you already use. Start with the [website and API hosting guide](/en/tutorials/how-to-deploy-your-website), then pick your framework below: each card opens a step-by-step guide with code.
### Frameworks
### APIs and backends
Not on the list? Virtually any other framework or library runs too: if it starts a web server on port 80, it runs on Square Cloud.
### Languages
## Developer ecosystem
Deploy and manage your site from wherever you work:
* **[Square Cloud CLI](/en/cli-reference/quickstart):** deploy, restart and follow logs from the terminal.
* **[VS Code extension](/en/vscode-extension/installation):** manage your applications without leaving the editor.
* **GitHub:** every push to your repository can deploy automatically, by [connecting your GitHub repository](https://help.squarecloud.app/en-us/article/how-to-connect-your-github-repository-and-deploy-automatically-mr6srt/) or from a [GitHub Actions workflow](https://help.squarecloud.app/en-us/article/workflow-github-actions-automated-deploy-ff34mk/).
* **[SDKs](/en/sdks/introduction) and [REST API](/en/api-reference/introduction):** automate anything the dashboard does.
## How to host my website?
Create a `squarecloud.app` file at the root of your project. The [configuration file guide](/en/getting-started/config-file) explains every field. A website also needs:
* **SUBDOMAIN:** the address of your site. `SUBDOMAIN=test` serves it at `test.squareweb.app`.
* **MEMORY:** the RAM reserved for it, **512 MB at least**.
Set `SUBDOMAIN` before the first upload. An application deployed without it can't become a website later: you would have to upload it again as a new application.
Keep your dependencies file in the project: `package.json` for Node.js, `requirements.txt` or `pyproject.toml` for Python. Square Cloud installs everything it lists on the server. Leave out built-in modules, such as `fs` in Node.js or `random` in Python, since they come with the language.
Compress your code, the configuration file and the dependencies file into a `.zip`. Leave out `node_modules`, `__pycache__`, lockfiles such as `package-lock.json` and other generated files: dependencies are installed on the server, and a smaller upload deploys faster. The CLI and the VS Code extension leave lockfiles out for you. Need pinned versions? Add `!package-lock.json` to your [squarecloud.ignore](/en/getting-started/squarecloud-ignore) file.
Your app must listen on **port 80** and host **`0.0.0.0`**. The runtime images already set the `PORT` and `HOST` [environment variables](/en/platform/environment-variables) to these values, so a server that reads them needs no change. Visitors reach your site over HTTPS, and Square Cloud handles the certificate.
Send the `.zip` on the [upload page](https://squarecloud.app/en/dashboard/new). Square Cloud installs the dependencies, sets up the environment from your configuration file and puts your site online.

## Frequently asked questions
We recommend the **Standard** plan, from **R$44.99/month** with 4 GB of RAM and 4 vCPUs, which also unlocks custom domains. A lighter site also runs on the **Hobby** plan, from **R$12.49/month**: a website needs at least 512 MB of RAM. See [Plans and Pricing](/en/platform/plans) for the full comparison.
Yes. Every web deploy includes a `*.squareweb.app` subdomain at no extra cost, as part of your plan. It's ready to use as soon as you set the `SUBDOMAIN` field in your configuration file.
Custom domains are available from the **Standard** plan and up. Square Cloud does not register or sell domain names: the feature connects a domain you already own at a registrar, one hostname per application (such as `example.com` or `www.example.com`). Follow [how to set up your own domain](https://help.squarecloud.app/en-us/article/how-to-set-up-your-own-domain-cnamedns-1fzbrgh/) for the DNS records, and see [why a domain hasn't propagated yet](https://help.squarecloud.app/en-us/article/why-hasnt-my-domain-propagated-yet-dns-f5jzoy/) if it doesn't load. To attach it from code, use [Set Custom Domain](/en/api-reference/endpoint/apps/network/custom).
