Top 5 Documentary Streaming Services in 2025
Pros
- Extensive library of high-quality documentaries.
- Affordable pricing.
- Wide range of educational subjects.
Cons
- No dedicated mobile app.
- Limited amount of original content compared to some competitors.
Key Specifications
Curiosity Stream is an excellent choice for documentary enthusiasts seeking a vast library of factual content at an affordable price. It provides a wide range of documentaries across various subjects, including science, history, nature, technology, and society. This service stands out due to its extensive collection and budget-friendly subscription tiers, offering significant value. While the user interface could be slightly improved and the amount of original content isn't as high as some larger competitors, Curiosity Stream delivers high-quality streaming and an impressive selection of educational and engaging films.
Pros
- Large library of original documentaries.
- User-friendly interface.
- Wide variety of non-documentary content.
Cons
- Subscription cost is higher than some competitors.
- Documentary selection is only a portion of its massive content library, so it may provide more of a 'jack-of-all-trades' offering but not a specialization.
Key Specifications
Netflix provides a substantial selection of documentaries, alongside its extensive original movies and TV shows, offering a wide variety of content from true crime to nature and social issues. Its strength lies in combining its large and well-produced original documentaries with a broad range of third party options, making it a solid entertainment hub overall. Netflix's user interface is very intuitive, making it simple to search and discover content. However, if documentaries are your priority, the vast selection means the documentary catalog is a subset of the service, and it would not provide as deep a specialized library as a service like Curiosity Stream.
Amazon Prime Video
Best If You Already Subscribe to Amazon Prime
https://www.amazon.com/gp/video/getstarted/Pros
- Good selection of documentaries.
- Included as part of Amazon Prime subscription.
- Offers a wide array of non-documentary content.
Cons
- Requires an Amazon Prime subscription.
- Documentary selection is mixed in with other content which can make it challenging to find specifically documentaries.
Key Specifications
Amazon Prime Video offers a good selection of documentaries as part of its broader streaming service, which combines access to movies, TV shows, and original content. Its documentary offerings cover a range of subjects, featuring both original productions and licensed films. The integration within Amazon's ecosystem provides added benefits, such as access to exclusive content, but makes Amazon less focused on documentaries compared to dedicated documentary channels like Curiosity Stream. Overall, it's a good addition for Prime members looking to stream documentaries along with their regular content.
Pros
- Specialized focus on history, science, and nature documentaries.
- High-quality, in-depth content.
- Minimal ads.
Cons
- Smaller library compared to bigger services.
- Focus is niche
- Lacks other entertainment options outside of documentaries

It is a very good resource for those looking for a niche, but could be limiting due to the lack of variety compared to services that offer much broader content libraries. Magellan TV is a good option for a highly-specialized documentary experience.
Pros
- Free access through libraries and universities.
- Good selection of award-winning documentaries.
- Curated content.
Cons
- Limited selection of 4k content.
- Can be expensive
- Limited number of original documentaries

For a vast and varied library with high-quality content, a service like Curiosity Stream is hard to beat, especially for the price.

Ultimately, the best choice is the one that aligns with your viewing habits and budget.
