kevinchalet.com is the personal technical blog of Kévin Chalet, who describes himself as a “.NET-holic and OpenID-addict” based in France. The crawled content is almost entirely focused on OpenIddict: an OAuth 2.0/OpenID Connect client, server, and validation stack for the .NET ecosystem. The site feels more like a maintainer’s blog and technical announcement hub than a conventional SaaS product website.
Based on the posts, OpenIddict covers ASP.NET Core, .NET Framework 4.6.2+, .NET Standard, OWIN/Katana, and classic ASP.NET scenarios. Recent versions highlight features such as OAuth 2.0 Token Exchange, mTLS, client assertions, relaxed redirect_uri policies for native applications, static token lifetimes, and token formats based on JWT and ASP.NET Core Data Protection. It also provides NuGet packages and APIs, including OpenIddict.AspNetCore, EntityFrameworkCore and MongoDB integrations, plus APIs related to authorization and token revocation.
The content does not mention commercial pricing, subscriptions, enterprise support, or payment methods. OpenIddict packages are published on NuGet.org, changelogs are hosted on GitHub, and the text also references documentation and migration guides, so its usage model is closer to that of an open-source .NET library. Self-hosting is clearly supported: developers can run the authorization server and validation stack in their own ASP.NET Core applications, databases, EF Core, or MongoDB environments.
The main strengths are the high density of technical information, detailed notes on version compatibility, breaking changes, and migration paths, plus complete code examples. It is especially useful for .NET teams dealing with complex identity protocols. The downside is the relatively high entry barrier: much of the content assumes readers are already familiar with OAuth 2.0, OIDC, ASP.NET Core Identity, and EF Core. Also, it is not a commercial support page, so there is little information on SLAs, customer case studies, compliance, or paid support.
It is best suited to backend and platform teams that need to build their own authentication and authorization system in .NET/ASP.NET Core, migrate between OpenIddict versions, or deeply customize token handling workflows. The content does not provide information about access from China. Dependencies such as NuGet and GitHub may be affected by local network conditions, so preparing mirror sources or a proxy is recommended. Alternatives include IdentityServer, Duende IdentityServer, Keycloak, Auth0, and ASP.NET Core Identity.
