Local development → public web, without friction

Take local websites live in a click.

KillTheHost brings together PHP-MNGR and DB-3NGIN3 into a single workflow for running local sites, managing databases, syncing domains, and exposing projects to the public web. Connect your Namecheap domain, link your Cloudflare account, and move from localhost to a live URL without manual setup or complex networking.

Products

Run your stack locally. Publish it globally.

KillTheHost removes the gap between development and deployment. Manage your application layer with PHP-MNGR, control your data layer with DB-3NGIN3, then connect domains and expose everything through Cloudflare — all from one interface.

01 · PHP site management

PHP-MNGR

🐘

PHP-MNGR is a local control panel for PHP projects. It lists each site with its runtime state, port, PHP version, and filesystem path, and gives you direct actions to start, stop, and open projects instantly. It replaces fragmented terminal workflows with a single, consistent interface.

02 · Database service management

DB-3NGIN3

🗄️

DB-3NGIN3 manages your local database services in one place, including PostgreSQL, MySQL, MariaDB, Redis, and MongoDB. Each service exposes its running state and port, with simple controls for starting and stopping instances without relying on CLI commands.

Why it matters

From local development to live deployment, simplified.

KillTheHost is built around a single idea: your local environment should not be isolated. It should be easy to connect to real domains and share with the outside world.

🌐

Namecheap domain integration

Connect your Namecheap account and sync domains directly from the panel. Assign domains to local sites without manually editing DNS records. Support for additional providers is planned.

☁️

Cloudflare tunnel integration

Link a free Cloudflare account and expose local services through secure tunnels. No port forwarding, no router configuration, and no manual tunnel scripts required.

🚀

One-click public access

Once connected, your local site can be reachable on the public internet in seconds. Ideal for previews, demos, client reviews, and testing real-world behavior without deployment overhead.
