Software Development Review from David Szebeni
Finding the perfect partner is the most important step in a business. And a software partner is one of the most difficult in the life of a modern company. We are at the very end of a very long project with WebOrigo. Behind the program there is almost 2 years of joint cooperation. In which there were very difficult moments and circumstances, since the introduction of a new ERP is not smooth. Regardless, all obstacles and difficulties were dealt with in a very flexible and professional manner. In WebOrigo I found a reliable and professional software production company, I recommend them with confidence. However, I would like to inform all companies that want to create software that a lot of patience is needed to develop a program. In addition, I think it is very important that every customer is 100% sure of what they want.

Small Businesses Website Development Review from Irena Bulka
We collaborated with 5Hz on the development of a corporate website for our custom Christmas ornament business, and overall, the experience was very positive.Our main goal was to create a modern, user-friendly website that would clearly present our brand, services, and values. The 5Hz team handled the full development cycle, including business analysis, requirements clarification, UX/UI design, development, and technical implementation. As a result, we received a fully functional website with a clear structure, responsive design across different devices, and an easy-to-manage content system. They also supported the testing, launch, and post-launch stages, ensuring everything worked smoothly.The project was delivered on time and according to the agreed scope. The new website significantly improved our online presence: it clearly reflects our brand positioning, is intuitive for users, and provides a better overall experience. It also helped streamline communication with potential clients and partners by making information more structured and accessible.From a technical standpoint, the website is stable, performs reliably across devices and browsers, and is easy for our team to update without сложности. This gives us a strong foundation for further digital growth.We also appreciated their professional approach to project management. Communication was smooth and efficient throughout the process via virtual meetings, email, and messaging apps.Overall, we are very satisfied with the collaboration and have no areas for improvement to highlight.

WordPress Review from Christine Zapata, SHRM-CP, MBA
I recently had the pleasure of working with Dotix (dotix.co) for the redesign of my website, and I can confidently say that they have transformed my online presence! From the very beginning, the Dotix team was incredibly supportive and attentive. They met with me weekly, as per my request, to discuss design elements and establish clear next steps and action items. This commitment to collaboration made the entire process smooth and enjoyable.One of the standout aspects of my experience was their exceptional responsiveness. Whenever I needed to provide information or had questions, they followed up promptly, ensuring that I never felt lost or overwhelmed. Their dedication to customer service is truly commendable!The end result? A beautifully designed website that looks extremely professional. They utilized WordPress for the redesign, which was a requirement for me, and they even provided a training guide that empowers me to edit and update my site independently. As a small business owner, being able to manage my website without incurring additional costs is invaluable.Additionally, I was pleasantly surprised the entire cost of the redesign fit perfectly within my budget, making their services accessible without compromising quality. I also learned that Dotix is expanding their services to the United States, which is fantastic news for anyone looking for top-notch web design and SEO solutions.In conclusion, I highly recommend Dotix for your website redesign and SEO programming need. Check out their website for the other services they provide. Their professionalism, creativity, and commitment to client satisfaction set them apart in the industry. Thank you, Dotix, for your incredible work!

Every agency is independently vetted before it can be listed or ranked
Some agencies pay for sponsored placement, clearly labeled and held to the same vetting standards.
Blockchain development agencies design, build, and support blockchain-based solutions that automate processes, improve transparency, and enable secure digital transactions.
Common services include:
Blockchain development firms use a mix of public networks, enterprise platforms, and developer tools to build, deploy, and manage blockchain solutions. They choose platforms based on speed, cost, scalability, and whether the project needs a public or private network.
Key platforms and networks:
Development tools and infrastructure that blockchain development agencies use:
Blockchain development companies typically charge from $40,000 to $300,000+ for a full solution, depending on complexity, features, and security requirements.
The biggest cost driver is the solution's complexity, from basic smart contracts to full-scale platforms.
Different blockchain products have different price ranges based on functionality.
Your budget is split across multiple phases, not just development.
Final pricing depends on scope, security level, integrations, and whether you build on an existing blockchain or create a custom one.
Ongoing blockchain costs typically range from 15% to 25% of the initial development cost per year, depending on system complexity and usage.
Key ongoing costs include:
Costs increase as the system scales, handles more transactions, or requires higher security.
The best blockchain development company typically needs 3 to 9+ months to build a blockchain solution, depending on complexity, features, and security requirements.
Typical timeline by complexity:
Blockchain development agencies build products in stages, and each is adding time:
Factors that affect the timeline include scope and feature set, choice of blockchain platform, team experience, and whether you build from scratch or use existing tools.
Public blockchains are open to anyone, while private blockchains are restricted to approved users and controlled by an organization.
You can see the main differences in the following table:
| Feature | Public blockchain | Private blockchain |
| Access | Anyone can join | Permission required |
| Control | Decentralized | Controlled by one entity or group |
| Transparency | Fully transparent | Limited visibility |
| Speed | Slower | Faster |
| Cost | Higher (transaction fees) | Lower |
| Security | High through decentralization | High, but depends on governance |
| Use cases | Crypto, DeFi, NFTs | Enterprise systems, internal operations |
Blockchain development firms ensure security by combining secure coding, testing, and continuous monitoring to prevent vulnerabilities and protect data and transactions.
Key security practices include:
Security is built into every stage, not added after deployment.
