+synopsis: Remove experimental repl-flake
+significance: significant
+issues: 10103
+prs: 10299
+---
+
+The `repl-flake` experimental feature has been removed. The `nix repl` command now works like the rest of the new CLI in that `nix repl {path}` now tries to load a flake at `{path}` (or fails if the `flakes` experimental feature isn't enabled).*
