As answered by people managing LeetCode and Test Surely.
Test Surely's answer:
HTML, Tailwindcss, React, NextJS and Supabase
Test Surely's answer:
Surely stands out because it was born from empathy for QA engineers overwhelmed by too many tools, requirements, and expectations. It saves time by streamlining the organization and tracking of open tabs and browsers, reducing friction and freeing up QA engineers to focus on productivity.
Test Surely's answer:
Choose Surely over competitors because it's built from real empathy for QA engineers' common struggles, like cluttered desktops, lost tabs, overlooked activities, and missed defects. Beyond just streamlining and organizing workflows, its AI assistant is always on hand to brainstorm issues, draft concise defect reports, and deliver over 70% productivity gains.
Test Surely's answer:
The primary audience for Surely is QA engineers and software testers in tech teams, particularly those juggling multiple tools, browsers, and tasks while dealing with cluttered workflows, defect tracking, and productivity challenges
Test Surely's answer:
Surely was born out of real frustration. A QA engineer, overwhelmed by juggling too many testing tools, lost productivity, missed bugs, and rising subscription costs, decided something had to change. After a critical bug slipped through during a late-night testing session, I created Surely to simplify QA work, organizing tabs, streamlining workflows, and using AI to help document issues, without expensive subscriptions. Surely exists to give testers back their time, focus, and sanity.
