How do I open a .META file?

Drop a .META file onto Analyser at https://analyser.valjdakosta.com/ and it opens directly in your browser - no upload, no account and no software to install. Open Unity game-engine assets in the browser. Unity serialises scenes (.unity), prefabs, Animator Controllers (.controller), animation clips (.anim), materials (.mat), physics materials (.physicsMaterial2D) and other assets (.asset) as a YAML object stream, with a .meta importer record (carrying the asset GUID) beside every file. Analyser splits the object documents and reads each - a scene's GameObjects and component-type breakdown (Transform, SpriteRenderer, colliders, scripts), an animation's sample rate and curves, a controller's layers and states, a material's friction and bounciness, and a .meta's GUID and importer.

Can I open a .META file online for free?

Yes. Analyser is a free online .META opener and viewer that runs entirely in your browser - your .META file never leaves your device, so there is nothing to upload and no software to install. It even works offline once installed.

What is a .META file?

META is the sidecar Unity writes next to every asset - a YAML record holding the asset’s stable GUID and its import settings. Created and opened by the Unity editor.

Did you know: Deleting a .meta file makes Unity re-import the asset with a brand-new GUID, which is why every reference to it breaks.
Unity never edits your source files; each one gets a .meta sidecar, and the GUID inside is how references survive even when an asset is moved or renamed.
Not committing the .meta files is a classic Unity mistake, because it breaks every link that pointed at the asset.
