The show has gained popularity and positive reviews, so naturally fans are trying to watch The Flash online free. Here’s a look at your best options.

If you’d like to enjoy The Flash live stream, or you’re looking to binge-watch The Flash full episodes using an on-demand service, the options below are your best bet.


Watch The Flash Online With Hulu

Best Choice
$39.99 - $43.99

Update October 2016: If you’re wondering, is The Flash on Hulu? The answer is, unfortunately, no. Hulu is not currently offering The Flash streaming. We’ll keep you posted if this changes.

If you want to make sure you don’t miss an episode of The Flash, Hulu is the best bet. (Find our overall thoughts on Hulu here). Hulu offers up the latest five episodes of The Flash, with new ones available a little more than a week after they air on TV.

Hulu has a huge library of hit TV shows like Seinfeld and Grey’s Anatomy, along with movies like Interstellar and original shows like Casual. Hulu is available for as little at $7.99 a month ($11.99 with no commercials), and is giving customers the chance to try them out for seven days completely free.


The Flash Live Stream is Available Through the CW App

The CW app is available on almost any Android or Apple device, and has a few The Flash free episodes available for streaming. Most TV network apps require you to have a cable company account that you can log in with, but with CW that is luckily not the case. If you just want to check out a few episodes to see what the show is about, this is the way to go to watch The Flash online free.


Is The Flash on Netflix?

Netflix currently offers past seasons of The Flash for on-demand streaming! This is great news, considering that many of our readers probably have Netflix already.


Is The Flash on Amazon Prime?

Unfortunately not. Although Amazon Prime is known for having the impressive selection of the Amazon Prime Instant Video library, that library does not currently offer The Flash.


Watch The Flash Live With an Antenna (for Free!)

The Flash airs on the CW network, so there’s a good chance you can pick up an HD digital signal with just an antenna that hooks directly to your television. This could allow you to watch shows from ABC, CBS, Fox, NBC and more live. We put together a guide to the best antennas available. You also may want to consider using a DVR to record the show, giving you added flexibility.


Buy Episodes of The Flash To Own and Watch Anytime

The day after The Flash airs on television, episodes are available to buy on Amazon Instant Video. Vudu also has single episodes of The Flash not long after they air on TV, as does iTunes. Remember that if you do choose to watch The Flash this way, you’re going to end up paying much more over time.

If you’re going this route, the discounted season pass is the best option. You own the content for life, and new episodes will be sent to your account soon after they air.

You will own the episodes permanently to watch any time, but for the price of a handful of episodes, you could subscribe to a monthly service and have access to most of your favorite shows.

We hoped this guide covered everything you need to know to watch The Flash online.
