- Manus Handles the Rest: Manus will take care of the entire deployment process, including:
- Provisioning the necessary cloud infrastructure.
- Building and optimizing your application for production.
- Deploying it to a secure, scalable hosting environment.
- Configuring the necessary DNS settings if you are using a custom domain.
Custom Domains: Professionalize Your Brand
Give your web application a professional and memorable address by connecting your own custom domain. Manus makes it easy to publish your site to any domain or subdomain that you own.
Connecting Your Domain
To connect your domain, you simply need to tell Manus which domain you want to use. For example:“Publish this site to my custom domain, www.example.com.”Manus will then provide you with the necessary DNS records that you will need to add to your domain registrar’s settings. This typically involves adding or updating an A record or a CNAME record.
Purchasing a Domain
Purchasing a custom domain inside Manus is now one of the fastest steps in going live. Instead of bouncing between external registrars and juggling DNS settings, you can search, buy, and secure your domain directly within the builder. Everything updates on the same page, and Manus handles the setup behind the scenes. This means you can move from prototype to a fully branded, public site in minutes. Whether you are launching your first product or taking an existing project live, buying your domain through Manus keeps the entire process simple, consistent, and fast.Automatic SSL/HTTPS
Security is handled automatically. Once your domain is connected, Manus will provision and configure a free SSL/TLS certificate for your site. This ensures that all traffic to and from your application is encrypted, providing a secure experience for your users and improving your site’s search engine ranking.Hosting Modes
When you publish a web application, you can choose between two hosting modes depending on your needs.Autoscale (Default)
Your application runs on Google Cloud Run. It scales from zero when there’s no traffic, and scales up automatically to handle demand.| Spec | Detail |
|---|---|
| CPU | 1 vCPU per instance |
| Memory | 512 MB per instance |
| Auto-scaling | 0 to 5 instances |
| Cold starts | Yes — instances spin up on first request after inactivity |
| Region | US (default) |
| Pricing | Billed per active request duration. $0 when idle. |
Reserved
Your application runs on a reserved instance. It stays running continuously — there are no cold starts and no request timeout.| Spec | Detail |
|---|---|
| CPU | 1 vCPU |
| Memory | 512 MB |
| Auto-scaling | No — single persistent process |
| Cold starts | No — always warm and ready |
| Region | US (default) |
| Pricing | Billed by actual CPU and memory consumption. Up to ~$36/month at full utilization. |
Choosing Between Them
| Consideration | Autoscale | Reserved |
|---|---|---|
| Traffic pattern | Sporadic or bursty | Continuous or event-driven |
| Cost when idle | $0 | Low (idle process still consumes minimal resources) |
| Persistent connections (WebSocket, SSE) | Not recommended | Recommended |
| Background workers / queues | Not supported | Supported |
| Handles traffic spikes | Yes — auto-scales to 5 instances | Throttled — single instance may slow under heavy load |
