Frequently Asked Questions

Pre-Purchase Questions

Is Noctiluca Server free?

Noctiluca Server is a paid software product. It is currently offered at a discounted price during the Early Access period. You can check the detailed pricing information here.

You can try the trial version for free for 7 days before purchasing. The trial version includes all features, so you can thoroughly test it before deciding whether to buy. Rather than purchasing right away, we recommend trying the trial version first.

Additionally, Noctiluca Server can be refunded within 14 days of purchase for any reason. For more details on the refund policy, please refer to the Refund Policy page.

What features does Noctiluca Server have?

As it is currently in the Early Access stage, it includes basic remote desktop functionality and security features. Future updates will add various features such as a plugin system, AppStream, and more. You can check the detailed feature list and roadmap on the Server Implementation Status page.

Can multiple users connect to a single computer simultaneously using Noctiluca Server?

Noctiluca Server currently supports only one remote session at a time. In other words, multiple users having their own graphical sessions simultaneously is not supported.

Additionally, this usage method violates the macOS EULA, so there are no plans to support it in the future. We appreciate your understanding.

How many computers can I install Noctiluca Server on with a single license?

A single Noctiluca Server license can be installed and used on up to 2 computers.

Is there a separate enterprise license?

At this point, as we are in the Early Access stage, only consumer licenses are available, and enterprise licenses are not sold separately. If you have any inquiries, please contact us at [email protected].

General Questions

I want to completely uninstall Noctiluca Server.

To completely uninstall Noctiluca Server, please follow these steps:

  1. Move the Noctiluca Server app to the Trash.
  2. Step 1 is usually sufficient, but to completely remove all related files, delete the following Noctiluca Server files and folders:
    • ~/Library/Application Support/app.noctiluca.server
    • ~/Library/Preferences/app.noctiluca.server.plist
    • ~/Library/Caches/app.noctiluca.server
    • ~/Library/Logs/app.noctiluca.server
    • /etc/pam.d/noctiluca (if PAM authentication was configured)

Security Questions

I want to use an SSL/TLS certificate issued by a trusted CA.

Noctiluca Server uses a self-signed certificate by default to secure TLS connections. However, it is also possible to use a certificate issued by a trusted CA.

To replace the certificate, please follow these steps:

  1. Import the certificate and private key you want to use through the Keychain Access app. Both the certificate and private key must exist in the Keychain.

  2. Open the Noctiluca Server settings and navigate to the 'Security' tab.

  3. In the 'Transport Layer' section, uncheck the 'Automatically configure server certificate' option.

  4. Click the 'Import Certificate' button to select the desired certificate from the Keychain.

  5. Save the settings and restart the server.

Connection Questions

I set up port forwarding on my router/firewall, but I can't connect from outside.

Noctiluca Server uses QUIC as its transport layer. Since QUIC is a UDP-based protocol, you need to open the UDP port, not the TCP port, when configuring port forwarding.

I changed the default port (8282), but I can't connect from outside.

Please make sure you stopped and restarted the server from the tray menu. Port number changes require a server restart to take effect.

Plugin / Sirius Protocol Questions

When will the plugin SDK be released? What language should I develop in?

The plugin SDK (NoctilucaPluginKit) is targeted for release in Q3 2026. You will be able to develop using Swift, and in theory, mixing in Objective-C / C++ should also be possible.

When will libsirius be released as open source?

The Sirius protocol and its reference implementation libsirius are targeted for open source release in Q4 2026. The MIT License is being considered.

Miscellaneous

Can Noctiluca Server be used on Windows or Linux?

Currently, Noctiluca Server is only available on macOS. There are no plans to develop Windows or Linux versions at this time.

I found a security vulnerability. Where should I report it?

Please send security vulnerability reports to [email protected]. When reporting, please include a detailed description of the vulnerability, reproduction steps, and affected version information, and please follow responsible disclosure principles.

Do you operate a bug bounty program for security vulnerabilities?

We do not currently operate an official bug bounty program at this stage. However, we are always grateful for security vulnerability reports, and we may consider providing appropriate compensation for critical vulnerabilities. Please inquire when submitting a security report for more details.
