It's not just about the books! **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Government Administration | Enterprise (> 1000 emp.) **Reviewed Date:** June 27, 2024 **What do you like best about O'Reilly?** There are so many options to learn: Video on demand, sandboxes to play in and live webinars! I find that I reference specific chapters of books rather than reading the whole book. The search utility allows me to see chapters instead of just returning titles. I like that it's easy to use and pretty consistent across platforms. I also like that there is a productivity category. I find a few gems in there to help me with my day. Pretty much anything I need to reference will be in O'Reilly. **What do you dislike about O'Reilly?** There aren't any real downsides to using O'Reilly. The only issue I have is that AI/LLMs are dominating my feed. I get it, LLMs are the rage right now, but I'd also like to see some variations based on my other interests. It's not that big of a deal as I know how to search, have my playlists, and can discover new stuff easily so I can deal with it until it blows over. **What problems is O'Reilly solving and how is that benefiting you?** I'm a Cloud Platform Engineer. I search for various pieces of information depending on what I'm doing, i.e. Infrastructure as Code like Terraform is a constant as well as Python for writing tools for the platform. But I also look at Go material for some of the existing tools. I haven't taken advantage of the sandboxes as much, though I'd like to and probably will soon. I also save a bunch of money not buying books when I only need a chapter or two out of one. But also I might not like a particular style so I can find a different book on the same subject. ### 16. Up-to-Date, Resource-Rich, and Easy to Use **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Retail | Small-Business (50 or fewer emp.) **Reviewed Date:** May 25, 2026 **What do you like best about O'Reilly?** Up to date information. Lots of resources. **What do you dislike about O'Reilly?** Nothing I can think of, I find the material helpful and the site easy to use. **What problems is O'Reilly solving and how is that benefiting you?** Keep up to date on technology and my skills ### 17. Wroth the subscription if you love reradinfg the books **Rating:** 5.0/5.0 stars **Reviewed by:** Manjunath J. | Principal AI Engineer, Enterprise (> 1000 emp.) **Reviewed Date:** July 03, 2025 **What do you like best about O'Reilly?** Platform not just for O'Reilly but also for Packt, Manning, Apress, and many other major publications, all in one place for the cost of just one book per month! Besides affordability, we offer collections, highlight important sentences, join live courses, and listen to audiobooks. It is AI-enabled, so if you don't understand any technical terms or want to explore further, there's no need to switch between ChatGPT—just ask AI directly within the book! It also has a mobile app, so you can use it on your phone or tablet and switch seamlessly between devices from where you left off! It integrates easily with all your devices. **What do you dislike about O'Reilly?** Frankly speaking, I do not see any downside, but it would be better if they could include some less known publications as well. **What problems is O'Reilly solving and how is that benefiting you?** As a Principal AI Engineer, it helps me solve customer problems efficiently! I used to read only AI books, which help me gain knowledge and apply it to solving real-world problems. ### 18. Rich, Wide-Ranging Content in an Easy-to-Navigate Platform **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Information Technology and Services | Enterprise (> 1000 emp.) **Reviewed Date:** April 30, 2026 **What do you like best about O'Reilly?** Depth and breadth of content. Also the ease of navigating through the platform. **What do you dislike about O'Reilly?** Price is high and also the online sessions have complex navigation. **What problems is O'Reilly solving and how is that benefiting you?** Mainly help with with upskilling and also with helping with Knowledge share for work. ### 19. Very easy to focus on development learning **Rating:** 4.5/5.0 stars **Reviewed by:** Maria Camila G. | Data scientist for cyber security, Enterprise (> 1000 emp.) **Reviewed Date:** September 03, 2025 **What do you like best about O'Reilly?** The easiness to find the course I'm looking for since there are very specific and there is not a ton of courses of the same topic so it's easier to choose one and focus my learning with practical exercises suggested in the curse. **What do you dislike about O'Reilly?** So far it has fulfilled my expectations on what to expect of the courses I've taken but I'm sure I'm missing many features that I have not explored yet. **What problems is O'Reilly solving and how is that benefiting you?** The content is really up-to-date so I can learn and have a deep dive on features that are maybe not that commercial yet so it's been a great tool for me to learn about new topics. It really helps me a lot when I'm trying to find information about a specific topic not having like 1000 courses to choose from but only a few verified and specific. Plus in the courses I've taken the tutors have been experts in the topic and their knowledge and easiness to teach have been great for me to understand new concepts ### 20. Engaging Live Events and Helpful Sandboxes **Rating:** 4.0/5.0 stars **Reviewed by:** Verified User in Telecommunications | Enterprise (> 1000 emp.) **Reviewed Date:** May 06, 2026 **What do you like best about O'Reilly?** I like the live events and the sandboxes on the platform. **What do you dislike about O'Reilly?** Some materials are poorly reviewed, discouraging learners from proceeding. **What problems is O'Reilly solving and how is that benefiting you?** The Q&A feature saves learners a lot of time. ### 21. A rare combination of variety, quality, depth, timeliness, and usability **Rating:** 5.0/5.0 stars **Reviewed by:** Adail R. | Estudante de Mestrado em Computação Aplicada, Mid-Market (51-1000 emp.) **Reviewed Date:** September 16, 2025 **What do you like best about O'Reilly?** I find books, courses, and events by authors with a great reputation and well-known in the market **What do you dislike about O'Reilly?** The number of offers generates a bit of anxiety, as I don't have much time to enjoy them. The price is also a bit high for developing countries, like Brazil. **What problems is O'Reilly solving and how is that benefiting you?** Keeping up to date in the field of technology is a huge challenge. Being able to rely on a varied and high-quality source of information, easily accessible, is a lever of opportunities for both the professional and the company. ### 22. Great upskilling platform **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Information Technology and Services | Enterprise (> 1000 emp.) **Reviewed Date:** September 24, 2025 **What do you like best about O'Reilly?** The type of content available is very complete and up to date. Also, they have a lot of technologies that you can learn and the instructors are of the best quality. Not sure there's anything else to say. I have never needed customer support and use it very frequently. It is very easy to use. Don't have an opinion on ease of implementation or integration but can use it in my laptop or iPad without any issues. Now that I know about it probably would get me a subscription on my own even if I change employers and my new employer doesn't give me a free subscription. **What do you dislike about O'Reilly?** The only thing I could say I don't like is that IMHO they keep too many old material listed. I understand that some old material can be valuable but some is not, given that they have newer material listed. New versions of frameworks or platforms come out and make older versions obsolete. In technology 1 - 2 years is a lot of time, so when you see material that is 5-10 years old it makes their library feel a bit bloated with obsolete info. I know you can filter old stuff but still, I think is not helpful to have a lot of the older (>5 years) material, unless is one of the classic/timeless material like the Code Clean book or stuff like that. But the Security+ material from 2 versions before is not really helpful since you cannot take test on that material. Other than that is a great platform. I'm happy my company give us a subscription. **What problems is O'Reilly solving and how is that benefiting you?** I'm able to learn technologies to solve current issues at my company. ### 23. Great courses in high variety **Rating:** 4.5/5.0 stars **Reviewed by:** Marcel H. | Principal Engineer, Enterprise (> 1000 emp.) **Reviewed Date:** September 01, 2025 **What do you like best about O'Reilly?** There is a very hough amount of online events, other courses, books and resources. Really good and I would recommend it as a first choice if you are looking for a learning platform. **What do you dislike about O'Reilly?** The price for individuals is not cheap, it could be more attractive. **What problems is O'Reilly solving and how is that benefiting you?** I had a great course about SQL that allowed me really to write much better SQL queries. ### 24. Excellent learning platform with wide variety of resources available **Rating:** 5.0/5.0 stars **Reviewed by:** Josh S. | Analyst, Enterprise (> 1000 emp.) **Reviewed Date:** September 16, 2025 **What do you like best about O'Reilly?** Wide variety of resources available such as eBooks that allowed me to study at my own pace. **What do you dislike about O'Reilly?** It was sometimes hard to find specific resources or determine which were better than others **What problems is O'Reilly solving and how is that benefiting you?** Develop and grow technical skills ### 25. Excellent learning materials on the O'Reilly platform **Rating:** 5.0/5.0 stars **Reviewed by:** Brie K. | Student, Small-Business (50 or fewer emp.) **Reviewed Date:** January 31, 2025 **What do you like best about O'Reilly?** The very best parts of O'Reilly in my mind are the webinars. First, there is something for everyone. If you're learning Linux, or Python, or AI, or studying for Security+, and just about any other tech topic, there is a webinar for you. Second, nearly every session comes with resources. I have many PDFs from the various speakers. It's great to be able to go back and look at materials. Finally, everything is recorded and a link is sent back to you when the recording is ready. **What do you dislike about O'Reilly?** Recently, O'Reilly switched to a new webinar provider and there have a been a few hiccups. Nothing that is a deal breaker, but the previous vendor was less problematic. **What problems is O'Reilly solving and how is that benefiting you?** I'm trying to skill up in many areas of tech and I can get everything I need to do so on the platform. Books, on-demand videos, webinars, lengthy content, and bite-sized content. ### 26. I trust the resources I find at O'Reilly and I have for years! **Rating:** 5.0/5.0 stars **Reviewed by:** Jared G. | Senior Database Administrator II, Small-Business (50 or fewer emp.) **Reviewed Date:** March 24, 2025 **What do you like best about O'Reilly?** The books that make up the core of the library are the highest quality. They provide good code examples that really get you started when you are looking for a quick answer on syntax. My physical library has many O'Reilly published books, so it makes sense that I would also look to them for an online library as well. **What do you dislike about O'Reilly?** Some of the books are getting a bit dated and haven't been refreshed. **What problems is O'Reilly solving and how is that benefiting you?** PostgreSQL knowledge, Python knowledge, DevOps knowledge, and the list goes on. These learnings help me in my job every day as a Database Administrator in an ever changing landscape. Today's IT Professional has to be a continuous learner and O'Reilly helps me do that. ### 27. Still the Best Tech Library **Rating:** 4.5/5.0 stars **Reviewed by:** Verified User in Information Technology and Services | Small-Business (50 or fewer emp.) **Reviewed Date:** March 25, 2025 **What do you like best about O'Reilly?** O'Reilly has a massive collection of tech books published by an array of authors from different publishers and different backgrounds. If reading isn't your thing then it has self driven sandbox courses. If self driven isn't your thing they have live courses with incredible industry savvy instructors. The amount of content is simply incredible compared to other platforms. **What do you dislike about O'Reilly?** While they do have coding sandboxes and courses, they're not as polished or comprehensive as other platforms (like say, Educative). The cost is another downside. For an individual who is paying their own subscription the cost is quite steep unless you use the platform rigorously or get a discount. For enterprise, I think the cost is a bit more fair. **What problems is O'Reilly solving and how is that benefiting you?** The primary problem that O'Reilly solves is having a diverse amount of content in a single platform. It saves users from having to have multiple subscriptions for different disciplines and fosters curiosity. ### 28. Comprehensive Resource for Professionals with Room for Improvement **Rating:** 4.0/5.0 stars **Reviewed by:** Flavio P. | Software Engineer, Enterprise (> 1000 emp.) **Reviewed Date:** January 09, 2025 **What do you like best about O'Reilly?** O'Reilly Learning Platform offers a vast and well-organized library of books, videos, and learning paths, making it an essential resource for professionals looking to expand their knowledge. Over the past year, I've been able to delve into specific topics, like Quarkus for Java, Go programming, and even career development strategies, by finding exactly what I needed in their catalog. I appreciate the ability to bookmark resources into an "interest list," which helps me keep track of subjects that matter most to me. The platform's focus on relevant, up-to-date content makes it easy to find guidance on new frameworks or emerging technologies. **What do you dislike about O'Reilly?** While the content itself is excellent, the application for accessing it, particularly on e-ink devices like my Boox Note Air 3C, leaves much to be desired. The app is not optimized for e-ink screens, resulting in glitches and occasional text display issues that require a refresh. It’s frustrating when trying to read on a device specifically meant for long-form content. Additionally, I feel the platform could improve by expanding its offerings in live courses, events, or even certifications—features I haven't explored yet but would find valuable in the future. **What problems is O'Reilly solving and how is that benefiting you?** O'Reilly helps me stay up-to-date with new frameworks, programming languages, and professional development topics by providing access to a vast and current library of resources. For example, when I needed to get familiar with Quarkus in Java or start learning Go, I found high-quality books tailored to these topics. It also helps me build a curated "interest list," which is great for organizing and prioritizing my learning path. This has significantly streamlined my ability to pick up new skills, making me more effective in my work and better prepared for challenges in my career. ### 29. Rich, high-quality book and video training library **Rating:** 4.0/5.0 stars **Reviewed by:** Verified User in Telecommunications | Enterprise (> 1000 emp.) **Reviewed Date:** September 30, 2025 **What do you like best about O'Reilly?** I can find good quality training on most technology subjects. Decent mobile app for on the go usage. **What do you dislike about O'Reilly?** The content is sometimes more oriented towards certain vendors, so it cannot be your one stop shop, it has to be complemented with other providers. **What problems is O'Reilly solving and how is that benefiting you?** Keeping up with fast evolving and broad technology landscape ### 30. O'Reilly, a pillar platform to enhance your knowledge **Rating:** 5.0/5.0 stars **Reviewed by:** Gildas S. | QA Engineer, Enterprise (> 1000 emp.) **Reviewed Date:** September 05, 2022 **What do you like best about O'Reilly?** The vast number of trainings available. The different support formats (books, on-demand courses...). The quality of the trainings. **What do you dislike about O'Reilly?** Depending of the product, it's sometime hard to find what you search because of the rich content available. In my opinion it's normal due to the size of the website. Live presentations are hard to take because they are mostly done in the USA at USA time - not easy to follow from France. **What problems is O'Reilly solving and how is that benefiting you?** Having a source of training on very different subjects. It's my source of truth for IT documentation. I can improve my skills on the subjects I'm very interested in. ### 31. Twenty years in and still going strong **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Government Administration | Small-Business (50 or fewer emp.) **Reviewed Date:** December 26, 2024 **What do you like best about O'Reilly?** The variety of books, videos, articles, live streams, sandboxes for learning new stuff, old stuff, and things only mentioned in passing. I work in a small "state/Local govt agency" where cross-training is key to meeting all the demands placed on the IT team. No training money in our budget, I scraped up the cash for my first O'Reilly account and have been a fan ever since (no corporate account for me). We actively search for new tech and ways to server our clients. O'Reilly has been my go-to choice to learn about emerging tech and to aid problem solving the old tried and true tech we stil have in play and must maintain. I thought O'Reilly was only tech info and training until I was pressed into a supervisor role. Info and resources in O'Reilly helped me get a handle on being a manager when no mentor was available. Twenty years and still going strong. This month I learning about Snowflake and trouble-shooting an old bash interface script. Neverstop learning. **What do you dislike about O'Reilly?** Can't say I have bad experiences, with books or humans. Firewall issues at work for a couple of live classes a few years ago but it was us not O'Reilly. So I just plan ahead for live courses with labs and do them off site. **What problems is O'Reilly solving and how is that benefiting you?** When boss says "would PostgresQL help us do X and Y" I goto O'Reilly and research. When my old Red Hat server had a NIC issue I used info in a well-worn O'Reilly BOOK to triage and help solve the issue. My go-to Oracle SQL language aid is a worn and faded O'Reilly pocket book that has not been reprinted but still has easy to access and still correct info. Unlikely to be updated yet still worth the original $10 on a weekly basis. I have some newer stuff online and print but I still like a good book. ### 32. Provides profound technical and practical knowledge **Rating:** 5.0/5.0 stars **Reviewed by:** Egmara A. | Data Scientist, Small-Business (50 or fewer emp.) **Reviewed Date:** December 06, 2024 **What do you like best about O'Reilly?** It's useful for staying up to date on new approaches that are emerging, such as Gen AI and Copilot, and it provides more detailed explanations of how unsupervised algorithms work than other courses I've seen. I like the hands-on experience, the insights from visualizing results and the variety of topics related to machine learning algorithms with python. **What do you dislike about O'Reilly?** Regarding the content, I'm enjoying it! What sometimes happens is that when I sign out and log in again to continue reading, the platform opens the book from the beginning of the chapter I'm on and not on the page I paused in the chapter. **What problems is O'Reilly solving and how is that benefiting you?** So far, the data visualization examples have provided great insights to take into my day-to-day work as a data scientist. It also allows me to learn how to apply unsupervised algorithms to practical problems since I have little experience with this type of algorithm. ### 33. The best learning Platform on the market.
