Conan Default Remote ✦ Original & Limited

Here’s a post tailored for a technical audience (e.g., DevOps, C++ devs, Conan users). You can use it for a blog, LinkedIn, or a community update.

The previous URL ( https://center.conan.io ) is now considered frozen as of November 2024. While it remains available to avoid breaking older Conan 1.x projects, it no longer receives updates.

In Conan, a "remote" is an abstract definition of a storage location for binary packages and recipes. Conan supports a list of remotes, functioning similarly to a stack or a prioritized list.

If a package isn't found locally, Conan iterates through its configured remotes in the order they are listed . conan default remote

conan remote list --raw > myproject/remotes.txt

Although Conan's architecture mitigates some typosquatting risks (by requiring explicit inclusion in conanfile.txt or conanfile.py ), the default remote remains an external attack surface. If a malicious actor were to introduce compromised code into a Conan Center recipe (via a compromised maintainer account or social engineering), that code would execute in the build environments of all users relying on the default remote.

As the Conan ecosystem has evolved, particularly with the transition to Conan 2.0, the definition and management of this default remote have shifted. The Evolution of the Default Remote Here’s a post tailored for a technical audience (e

If you’re managing multiple Conan remotes (Artifactory, Bintray legacy, or custom servers), you’ve probably run into this pain: forgetting which remote a package came from, or accidentally uploading to the wrong server.

While convenient, reliance on the default remote introduces Supply Chain Security vectors that organizations must mitigate.

For professional environments, relying solely on the public "default" is often discouraged: While it remains available to avoid breaking older Conan 1

Organizations should enforce configuration via conan config install . This command can apply a remotes.txt file that removes the public Conan Center default and replaces it with the corporate proxy.

Conan enforces SSL/TLS by default. However, in corporate environments with "SSL Inspection" proxies, certificate validation errors are common. Disabling SSL verification to resolve these errors exposes the client to MitM attacks, potentially allowing an attacker to inject malicious binaries during the download phase.
