Pros from Real Users

Pros

  • True native C# integration, eliminating the need to build and maintain Python microservices. Zero cloud dependencies or per-token API costs, allowing for predictable project budgeting. Excellent hardware acceleration that automatically targets CUDA or falls back to CPU seamlessly. Built-in capabilities like vector databases, OCR, and grammar-constrained generation save massive amounts of boilerplate code.
  • 1. Clean and Developer-Friendly API The library follows familiar .NET patterns, making it easy to adopt. Dependency injection support and clear interfaces reduces the time in getting started. 2. Abstraction Over Multiple Providers LM-Kit doesn’t tie you to a single LLM provider. This flexibility is valuable if you want to switch vendors or support multiple backends without rewriting your core logic. 3. Prompt Management It provides structured ways to manage prompts, which helps avoid scattered string literals across your codebase. This becomes especially useful in larger projects.
  • What I liked is that LM Kit works locally, so no need to send data to cloud. For my kind of apps where data matters, this is really useful. It can read documents and connect to DB which is exactly what I was looking for. Also flexible enough to integrate with .NET APIs and frontend. Once it’s set up, it does the job well.
  • Quick integration and faster responses compared to Ollama. I have used almost every other local tool but none oofer .net integration capabilities like this tool, or any other local usage method such as port integration or file importing and merging. Another good feature is that I can train models locally with my own data. Also the community license is free forever and can be shipped with your products with a reference the tool. Pretty good offer.
  • This SDK is so amazing. Got started within like 15 minutes of downloading it from nuget. Some of the features are really out of this world : 1) RAG pipeline - You can literally build your own data searching functions across the entire web using this. 2) Finetuning and Quantization both are available built in this package. I have built my own custom legal finetuned models available in Q6 and Q4 4 bits and 2bits (like literally custom functions which you can just run). 3) LORA adapters are also available in LM-Kit. You just have to prepare your own data and add it to this kit. 4) Load any publically available model from huggingface such as Mistral, Gemma, Phi etc. Works off the bat. So much available for so less. These people are seriously very hard working and provide amazing support for free (have answered all my questions in support email).
  • Fully local solution, with great integration with .NET. The API is very easy to use and samples are thorough, made RAG very easy to integrate into my project, plus a free community license!
  • Local / on-device inference & data privacy: LM-Kit.NET runs models entirely on your hardware (CPU/GPU/NPU). That means no data leaves your environment — ideal if privacy, compliance or sensitive data handling matters. Performance and low latency: Because inference is local, response times tend to be fast and predictable. The framework is optimized for performance across different hardware (CPU, GPU, Apple Silicon, etc.).
  • No need to use Python when developing .NET applications that use LLM. Very easy to use. Fast deployment. Samples that include most of the AI tasks.
  • This software is ideal for build AI models of all architectures in short time with a excellent quality of responses.
  • The ability to build AI functionality into Windows Forms applications by using it as a NuGet package.

  • As a professional who relies on workflow automation, I can confidently say that UiPath is one of the most user-friendly and versatile platforms available in the market. This platform has helped me and my team reduce manual efforts and save time by automating repetitive and mundane tasks. In this review, I'll share my experience using UiPath and the benefits it offers. One of the standout features of UiPath is its ease of use and learning. The platform offers a drag and drop functionality that allows non-technical users to create workflows without coding. The recording feature is also an excellent tool that can capture user actions and convert them into automation steps. I found it extremely easy to use and was able to start automating workflows quickly. This platform offers a wide range of pre-built activities that cover various applications and systems such as web, desktop, SAP, email, Excel, and more. This feature saves time and effort by eliminating the need to create custom activities. However, users can create custom workflows and activities to meet their specific automation needs. UiPath's robust orchestrator is another key feature that sets it apart from other workflow automation platforms. It can manage and monitor multiple robots in different environments, allowing users to schedule, activate, assign, and track automation jobs from a centralized dashboard. The orchestrator's analytics and reporting capabilities provide insights into the performance of the automation jobs, helping users identify areas for improvement. UiPath's strong artificial intelligence and machine learning component enable robots to handle unstructured data, natural language processing, computer vision, and cognitive automation. This capability enhances the automation process by providing intelligent insights and making automation more efficient. Users can also integrate UiPath with external AI platforms and services to further enhance their automation capabilities. It has a large and active user community that provides support, guidance, and best practices. The platform also offers free and open training courses through its academy, which helps users learn how to build bots from scratch, as well as advanced concepts. The training courses are easy to follow, and I found them to be incredibly useful in enhancing my skills and knowledge.
  • UiPath has a strong uniqueness that makes automation platforms fall a bit below it and that is that not only can you connect to external platforms through its API, but you can also apply UI automations, being able to interact through code internal of the different connected applications and can also interact through graphical interfaces of the different platforms that UiPath has. The possibilities that this platform has are very endless when it comes to automation to improve better workflows without having to put a lot of effort into programming this RPA. They have integrated artificial intelligence capabilities that can allow automatic learning models, which makes robots made with this platform more intelligent with information processing and can also generate more efficient optimization that can achieve the objectives set. With this feature, artificial intelligences can be created to perform different tasks, since they can be trained and then implemented in the required automations and can also be monitored in real time in order to see the impact that an artificial intelligence is causing, measuring its performance. and if the automation is working or not as planned during its construction. It allows an environment under the development of robots with low code, allowing automation to be carried out without requiring so much experience in a quick and easy way, through visual tools that can be used through the characteristics of drag and drop tasks that can be assigned and ordered by Steps. For more advanced and personalized features, tools or use, it will require some experience that I will leave in writing later to specify what I am trying to say, but for basic functions it is possible to have something and through trial and error it can be polished. robots so advanced that they can manage to satisfy certain needs. The community is very active and has a large number of developers who have experience in developing robots, this can be important in order to obtain knowledge and resources on how to have better efficiency by being able to create better quality robots that allow for better optimization in any area of work that is needed. Not only that counts with UiPath, but you can also find a lot of information through the blogs, webinars and courses that are on the website of this platform, I feel this is more useful to have good practices in automations. Also, within the UiPath community there is a large amount of material and solutions from other users that can be used for their own benefit or for a company that is looking for components that solve a problem but has little time to dedicate to building a robot or automation from zero scratch.
  • Works directly on UI layer, so no messing around with APIs and root access. Fairly easy to pick up in a short amount of time. Free version does enough for everyday users.
  • UiPath RPA is the most comprehensive robotic automation tool as it let us to automate almost every type of data workflows due to it's combability with many daily use applications and files.

Cons

  • Compared to some of its competitors, UiPath can be expensive, especially for enterprise level licenses. Additionally, the pricing scheme can be confusing and subject to frequent changes, making it difficult for companies to plan and budget for the platform. UiPath's slowness annoys me a lot, especially when dealing with large or complex workflows. Some users reported experiencing compatibility or stability issues with some activities or integrations, which may affect the efficiency and reliability of the automation process. UiPath's documentation for some of its newer features may be insufficient or out of date, making it difficult for users to fully understand and use these features. The support team can also be slow or unresponsive at times, which can be frustrating for businesses that require immediate assistance with troubleshooting or technical issues. As a result, some users may find that they rely more on user forums or online resources for help, which can be time consuming and less reliable.
  • While UiPath is a robust and versatile platform, there are some cons that users should keep in mind before investing in the platform. Here are some of the challenges that users may face while using UiPath. One of the primary concerns with UiPath is its cost. The platform can be expensive, particularly for small and medium-sized businesses that require multiple licenses or advanced features. Additionally, users may incur additional costs for cloud deployment, maintenance, and support. The pricing model of UiPath may not be suitable for organizations with a tight budget. Integration challenges can be another hurdle for users of UiPath. Users may face some integration challenges with complex IT infrastructures or legacy systems that may require custom scripting or configuration. This issue can result in additional time and effort required to integrate UiPath with existing systems. Another drawback of UiPath is that users may encounter some bugs or features that are unresponsive or unreliable. These bugs can hinder workflow automation and cause frustration for users. While UiPath has a large and active user community that provides support and guidance, it can still be challenging to resolve some of these issues. UiPath may also have some functionality and scalability limitations when dealing with large data volumes or image-based automation. Users may need some advanced knowledge or skills to handle some scenarios or use cases that are not covered by the pre-built activities or workflows. This issue can result in additional effort and time required to customize the platform to meet specific business needs.
  • You have to be familiar with this type of RPA platform, even more so when you have to connect the APIs of different web services that require automation through code, so you also have to have advanced programming knowledge to apply these improvements or automations. Therefore, if you are a private person with no prior knowledge of what I have just mentioned, you will need to invest a large amount of time and effort to learn about this platform and be able to handle it correctly in an effective way in order to achieve efficiency within the automations. There are many advanced features within this platform that you will need to go through certain challenges in order to fully understand the functionality of each tool or feature that UiPath offers. Keep in mind that there is a great risk when handling certain confidential information with this platform since, as I have said, it can handle automations both at the API level and also at the interface level, so certain storage data can be very confidential and that these robots can gain access to them. So you have to know about how privacy is managed and that the safeguarding of confidential information is being complied with since everything is stored in the cloud. I recommend that when using this platform for the first time, all available security measures such as two-step authentication are implemented, and that all data is encrypted for greater security and important data is not leaked.
  • Packages suddenly stop working and need to be downgraded to suit particular tasks. There are several errors which do not give proper information so troubleshooting is not easy at all. Design looks a little dated nowadays.
  • UiPath RPA performs well for all type of automations and no cons found.
