Duende Migration 2026 — check your code for free

Maps every Duende IdentityServer / IdentityServer4 call in Program.cs or .csproj to its OpenIddict equivalent and prices the Duende edition your setup needs today. Runs entirely in your browser — nothing is uploaded.

Free here: Scan one Program.cs or .csproj: every Duende call mapped to its OpenIddict replacement, plus the Duende edition and list price your setup needs.. In the editor: Whole-solution scan across every project, with a migration plan export (Markdown/CSV) per project for the pull request and the licence review. — that part asks for a licence key.

Same engine as the VS Code extension, byte for byte.
