Experimental

The experimental block is the catch-all for under-bake-still-on flags. The fields here are unstable: they get added, renamed, or removed between releases more often than the rest of the schema.

Options

Field	Type	Default	Allowed values	Description
fingerprints	[]string	[]	<sha256 hex>	Hex-encoded SHA-256 fingerprints of certificates that mihomo should trust regardless of the system trust store. Useful for self-signed control planes.
quic-go-disable-gso	bool	false	true | false	Disable Generic Segmentation Offload in the bundled quic-go stack. Set this if QUIC throughput is unstable on your kernel.
quic-go-disable-ecn	bool	false	true | false	Disable Explicit Congestion Notification probing in quic-go.
dialer-ip4p-convert	bool	false	true | false	Enable IP4P → IPv4 conversion for outbound dials (IPv6 addresses whose lower 32 bits encode an IPv4 endpoint).

Notes

• A field disappearing from this struct between releases is not a bug report — it has been either promoted to a stable section or dropped. Always check this page against the version of mihomo you are running.
