Are there any legitimate ways to read Marvel comics online for free, perhaps through official channels or trials often highlighted on Reddit?

Yes, legitimate options exist. Official services like Marvel Unlimited occasionally offer free trial periods (e.g., 7 days, 30 days) that are often promoted and discussed on Reddit. Additionally, many public libraries provide free digital comic access through services like Hoopla or OverDrive, which allow you to read a selection of Marvel comics with a valid library card.
