CYBER//HOST packs a full server stack into a single Android app — no root required, no cloud, no subscriptions.

SQLite Data API & Token Auth
Your phone isn't just serving files — it's a backend. Turn on the REST Data API and any SQLite table becomes CRUD endpoints under /data/<table>. Add the Auth API for user registration, login and bearer-token sessions, then require a valid token to read or write your data. Build a real full-stack app with the phone as the server.
- REST CRUD over SQLite (
/data/…)
- Configurable URL prefix per database
- User accounts: register / login / logout / me
Authorization: Bearer token sessions- Optional "require login" to protect data
- Runs behind every security layer & CORS

🖇
WebDAV Network Drive
Mount your website root as a network drive straight from Windows Explorer, macOS Finder or Linux — drag & drop files with no FTP client at all.
- Full read/write WebDAV (RFC 4918)
- Mount in Explorer / Finder / GVFS
- Authenticated with your FTP credentials
- Confined to the website root
- Large files stream straight to disk

🧩
Server-Side HTML Templating
An opt-in template engine renders shared headers, variables and simple logic into your HTML at request time — no build step, no framework.
- Includes / partials:
{{include header.html}}
- Variables from query & server values
- Conditionals:
{{#if}} … {{else}}
- Loops:
{{#each}} … {{/each}}
- Auto HTML-escaping (raw opt-in)

Dynamic DNS
Keep a hostname pointed at your phone even when your public IP changes. CYBER//HOST pings your provider's update URL on a timer.
- Works with DuckDNS, No-IP, Dynu & more
- Configurable update interval
- Set-and-forget background updates
New
🐘
Dynamic Scripting Engine
For advanced users, CYBER//HOST includes a complete CGI/FastCGI execution pipeline for PHP, Node.js and Python — every request passes through all the same security layers first.
- PHP via per-request CGI or persistent FastCGI
- Node.js & Python CGI runtimes
- Source is never leaked as plain text
Advanced / optional: these runtimes require a compatible native interpreter binary for your device — they are not bundled. Everything else on this page works out of the box.
