6 Best Software Testing and QA Companies in Singapore (2026)

Software testing is the step that catches broken checkouts, crashing apps and slow pages before customers do, and many Singapore teams buy it from an outside specialist rather than hiring a full QA department. This list brings together six providers whose own websites describe manual testing, test automation, mobile testing or performance testing, plus one platform company built around real-device measurement. Details below are reported as each firm publishes them and have not been independently audited. Use the entries to shortlist two or three, then ask each for a sample test report, a named lead tester and a written scope before you commit to a pilot.

TechTIQ Solutions runs a dedicated software testing and QA page aimed at startups and SMEs, and lists functional, performance, security, usability, compatibility, automation and user acceptance testing as separate services. It names Selenium and Cypress for automation, JMeter for performance work and OWASP ZAP for security checks, and says its compatibility testing covers different devices, operating systems and browsers. On pricing, the page offers only a loose statement that simple projects may start from a few thousand dollars, so request a written quote. The firm lists an office on Cecil Street in the CBD and also builds apps, which can help if you want one vendor to build and then test. A sensible option for smaller teams wanting a clearly itemised menu.

Singsys, which lists a Singapore office at High Street Centre, offers a standalone software testing service covering manual, automation and security testing. Its page breaks functional testing into smoke, module, integration, system, regression and user acceptance stages, and describes performance testing across load, stress, scalability, stability and volume. It names a long list of tools, including Selenium, Appium, Cypress, JMeter, Gatling, Postman and Katalon, and says team members hold ISTQB certification. The firm also states it has more than seventeen years of quality assurance experience, a figure we have not verified. Singsys also builds mobile apps, so it may suit teams wanting a separate testing arm that can work on someone else's build as well as its own.

Equative Solutions lists a Singapore office at Vision Exchange and publishes a software testing page describing dedicated QA teams and testing management. The services it names include automated testing for web, mobile and desktop software, cross-platform compatibility testing, performance and load evaluation, end-user acceptance validation, user experience audits and code quality reviews. It also mentions regulatory and compliance testing and post-development validation, which may appeal to teams that need evidence for an auditor rather than just a bug list. The page does not name specific tools or give turnaround times, so ask how a dedicated team would be staffed and how reporting would work. It is a reasonable candidate for companies wanting a longer-running QA arrangement rather than a one-off test cycle.

Softvil Technologies lists a Singapore address at The Central and publishes one of the wider testing menus in this group. Its page names manual testing, test automation, performance testing, security testing, API testing, compatibility, accessibility and localisation testing, along with mobile app and web testing. It also lists testing for less common targets, including cloud solutions, ERP software, blockchain applications, IoT products and AI applications. Elsewhere the firm describes consultancy on software quality management and testing process improvement. The breadth suggests it could handle unusual stacks, though a long list is not proof of depth in each area, so ask for examples close to your product. It may suit businesses testing enterprise systems or specialised platforms rather than a simple website.

Xsosys Technology presents itself as a manual and automation testing provider for web and mobile applications and lists a Singapore office at International Plaza on Anson Road. Its testing page sets out a long catalogue of test types, including smoke, sanity, integration, system, regression, user acceptance, load, stress, compatibility, security and usability testing. The company says it was established in 2009, though we have not verified that. Because the page reads as a service catalogue rather than a case study, ask for named examples, the test tools it would use and a sample defect report before committing. It may suit teams that want a plain, itemised testing scope covering both functional checks and the heavier load and stress scenarios before a launch.

TestingXperts is a quality engineering company whose site lists Singapore among its global offices, giving an address at People's Park Centre. Its service pages describe software testing, functional testing, test automation, web and mobile testing and performance testing, and it promotes proprietary automation tools called Tx-Automate and Tx-HyperAutomate. The site also cites a 2026 partner award from UiPath for agentic testing and a mention in a Gartner market guide, both as the firm reports them. As a larger international provider, it may suit organisations that want regional coverage or a long-term managed testing programme rather than a small local shop. Ask whether the people on your project would be based in Singapore or delivered from elsewhere, since the office listing does not say.
