Web3 Development Review from Marián ÄŚuprĂk
ORKA Systems did a great job for us. They delivered our website just as we wanted, and everything worked smoothly from start to finish. The team was easy to reach. Every time we had a question, they answered quickly and explained things clearly. We didnt waste time waiting for updates or chasing responses.Their technical work is solid. We asked for some custom solutions for our web3 development, and they handled even the tricky parts without any fuss. And they dont try to talk over your head with jargon. They keep things simple. The project cost was fair, with no hidden fees or surprise charges.We paid attention to the timeline, and ORKA delivered on schedule. The only delay we experienced was minor and well-communicated beforehand. I liked how the whole process was transparent. We always knew what was happening next.What stands out most is how willing they are to listen. If something was unclear, they fixed it fast. Our questions and suggestions were never ignored. Thats why I trust their team.In the end, our website looks good and runs reliably. It reflects what we wanted for our legal services business. If someone asked me to recommend a web development partner, I would mention ORKA without hesitation. No hype or big promisesjust honest work and good results.

IT Services Review from Jozef SemanÄŤĂk
Guys at ORKA systems helped my custom-bike building business not only by creating a very unique website for my company, but we are also using their own application (www.yeapp.app) for managing my business. Great cooperation - everything went perfectly!

Mobilunity Reviews & Testimonials
Dhaivat Dave's Review Sourced from Google
We’ve been working with Mobilunity since 2018 and have had an exceptional experience. We hired three frontend developers — Dmitriy, Serhii, and Marharyta — and they’ve been with us ever since. They’re among the best frontend engineers we've worked with: highly skilled in JavaScript, React, and CSS, extremely hardworking, detail-oriented, and always eager to learn.Even during very challenging times in Ukraine, they remained 100% reliable, committed, and always available. Not once have we faced delays or communication issues — a true testament to their professionalism.The support from the broader Mobilunity team has also been outstanding. Their local setup makes remote collaboration smooth, and they’ve gone above and beyond to ensure our team has everything they need to succeed. Highly recommended for anyone looking for top-tier remote talent and a reliable development partner!

Frequently Asked Questions About Software Testing Companies
What services do software testing firms provide?
Software testing companies provide different testing services to identify errors, security risks, performance issues, and how the software behaves in real-life situations and across devices. As part of their software testing service, they also check if each feature works as expected, fix bugs, make improvements, and make sure new software development updates don’t break existing functions, so the software quality remains stable.Â
Core services include:Â
- Functional testing Â
- Performance testing Â
- Security testing Â
- Usability testing Â
- Regression testing Â
- Automation testing Â
- Accessibility testing  Â
- Mobile app testing Â
- API testing Â
- Compatibility testing across devices/browsers Â
- Compliance testing Â
- Testing with artificial intelligence (AI) tools
- QA auditÂ
How much do software testing services cost?
Hourly rates for QA testing range from $25 to $200+. The final cost is determined based on the size of the software or application, its complexity, required testing type, tech stack (custom-built and older legacy systems cost more), and niche. Â
The rate will also depend on the seniority of the software tester. Across the United States, junior quality assurance (QA) tester may charge $70 to $110 per hour, while the rate for a senior QA mentor and automation engineer can range from $130 to $200 per hour. Â
Special software testing services such as QA audit goes from $5,000 to $25,000.Â
How can businesses know what type of software testing do they need?
Businesses can determine what type of testing solutions they need based on the potential impact of failures and the likelihood of defects. Namely, if they encounter:Â Â
- Core functionality issues: Use functional testing to verify features work as expectedÂ
- Unstable code or new features: Use unit testing for individual components and integration testing for modules working togetherÂ
- Poor system stability after updates: Seek regression testing to make sure new changes didn't break existing featuresÂ
- Performance and load issues: Use performance and load testing to evaluate speed and scalabilityÂ
- Security issues: Security and penetration testing are commonly used across apps handling sensitive user dataÂ
- Hard-to-navigate user experience (UX): Pursue usability testing to determine how intuitive the application is for end usersÂ
- Low compatibility across devices: Compatibility testing can evaluate how good the app works on different browsers, devices, and OS versionsÂ
There is also the option to choose between manual and automated testing. Â
Is automated testing more expensive than manual testing?
As an investment, automated testing is pricier than manual testing but offers a lower cost-per-test over time as it can run the same scripts repeatedly, without human intervention. Conversely, manual testing entails lower upfront fee, but its cost grows linearly as the project grows, as every test cycle requires paid hours from QA testers. Â
So, for short-term projects or ones with shifting requirements, manual testing is considered a more economical option, whereas for maintenance and regression cycles, automated testing grants better return on investment.Â
The main distinction between these methodologies is that manual testing relies on human observation and interaction to identify defects, whereas automated testing uses software scripts to compare outcomes against predicted results. Â
Manual testing is best suited for exploratory testing, usability assessments, ad-hoc bug hunting, and minor hotfix verifications where script development would be inefficient. Automated testing, on the other hand, is primarily used for regression testing to make sure the new code does not break existing features.Â
How do businesses measure the effectiveness of software testing?
The effectiveness of the software testing is measured via:Â
- Code coverage: The percentage of the code that has been testedÂ
- Defect density: The number of defects found per unit of codeÂ
- Test case effectiveness: The percentage of test cases that identify defects; helps prune redundant and ineffective testsÂ
- Time to detect and fix defects: The time it takes to identify and fix software defects and software bugsÂ
- Defect leakage: The number of bugs that "escaped" to production versus those caught during the testing phase Â
