The Developer Experience Gap

For too long, integrating privacy and security tools has been a manual, error-prone process. Developers are forced to read through pages of documentation, locate the correct entry files, and carefully paste snippets into their codebases. In an era of automated deployments and AI-assisted coding, this manual 'copy-paste' workflow is a relic of the past.

At CellWall, we believe that security should be invisible and integration should be instantaneous. Today, we are excited to launch the official CellWall CLI—a developer-first tool designed to automate the integration of the CellWall privacy engine into modern web projects.

Now Available on NPM

The CellWall CLI is now public and can be run instantly via npx: `npx @cellwall/cli init`

How it Works: Intelligent Integration

The CellWall CLI isn't just a simple script. It is an intelligent agent that understands the structure of your project. When you run the init command, the CLI performs a multi-step process to ensure a seamless setup:

Framework Detection

The CLI analyzes your `package.json` and project files to identify your framework (Next.js, React, Vue, Nuxt, SvelteKit, Angular, Astro, etc.).

Entry Point Discovery

It locates the optimal file for injection, such as `app/layout.tsx` for Next.js App Router or `src/app.html` for SvelteKit.

Safe Code Injection

Using robust regex patterns and framework-specific fallbacks, it injects the CellWall snippet into the `<head>` or equivalent configuration object.

Instant Verification

The CLI verifies the syntax integrity of the modification and provides immediate feedback on the success of the installation.

Built for Every Environment

We've engineered the CLI to be robust enough for even the most minimalist or non-standard project architectures. Whether you use a standard HTML boilerplate or a custom JSX layout with 'return children;', the CLI knows how to handle it.

Framework	Auto-Target	Injection Method
Next.js	app/layout.tsx	JSX Snippet / Head Component
Nuxt.js	nuxt.config.ts	Configuration Object Mapping
React / Vite	index.html	HTML Snippet Injection
Remix	app/root.tsx	JSX Fragment Wrapper
Astro	src/layouts/Layout.astro	Astro Fragment Injection
SvelteKit	src/app.html	HTML Snippet Injection
Angular	src/index.html	HTML Snippet Injection
Gatsby	gatsby-ssr.js	setHeadComponents Injection

Safety and Proprietary Security

We understand that your codebase is your most valuable asset. That's why the CellWall CLI is designed with a 'Safety First' philosophy. If the CLI cannot determine a 100% safe injection point, it will refuse to modify your files. Instead, it will provide an 'Assisted Manual Installation' guide, printing the exact code and steps needed for your specific environment.

You can run the CLI with the `--id` flag to bypass the interactive prompt: `npx @cellwall/cli init --id YOUR_PROJECT_ID`. This is perfect for quick local bootstrapping.

The Future is AI-Native

The launch of the CLI is just the beginning. We've also integrated an 'AI Agent Prompt' into our dashboard, allowing you to automate installation using tools like Cursor, Claude, or ChatGPT. At CellWall, we are building the privacy infrastructure for the AI era—making it faster, safer, and easier than ever to protect your users.
