Pull codebase updates, run sensitive package installations, and hot-reload your PM2 daemons entirely seamlessly behind the Nginx perimeter. Cosmic ensures your users never see a maintenance page.
Nginx automatically provisions isolated virtual hosts and routes custom domains to designated internal Node or Python ports. Every application is isolated in its own proxy-sandbox.
Built-in strict DNS propagation probing ensures Let's Encrypt TLS 1.3 certificates trigger perfectly upon explicit confirmation. Secure your endpoints with a single command.
Configure RAM and disk per-app with hard platform limits of 2GB RAM and 10GB disk. Live PM2 memory readings are updated continuously so you always know actual consumption.
Every deployment is permanently stored with its version number, type, and timestamp. Roll back to any previous version in seconds — no data loss, no downtime.
The platform auto-detects whether your domain needs a CNAME (for subdomains) or A-Record (for apex domains). DNS instructions are generated automatically in the dashboard.
