The best Storyblocks alternative is Pexels. It’s a tool that’s very similar to Storyblocks except there’s a lot less cool footage and everything is free to download. The main component that makes Storyblocks so much better than competitors is the fact that they pay creators money to upload footage to their archive. This drives a lot of motivated creators to add more footage to the archive.
Storyblocks is the best stock footage website I’ve used and they also have an easy video editor you can drop and drag from. I’m not sponsored by Storyblocks but actually just love their tool. There are alternatives to Storyblocks but they’re not nearly as good.
