// ISTQB Foundation

Severity ≠ Priority.

One of the most-confused concepts in QA. Severity is how badly the bug breaks the system. Priority is how urgently the business needs it fixed. Hover any cell to see what each combination demands.

S1 · Critical — data loss, outage, security breach.
S2 · Major — core feature broken, no clean workaround.
S3 · Minor — degraded UX, workaround exists.
S4 · Trivial — cosmetic, typo, polish.

// Why BugArena

QA finally has a league.

Devs have LeetCode. Designers have Dribbble. Testers have… outdated methods. We're fixing that.

Real broken apps

Not multiple choice. Not Jira screenshots. Live React, Node, and mobile builds with planted bugs ranging from off-by-one to auth bypass.

Skill-weighted scoring

Our engine grades you on severity, rarity, repro quality, and evidence. Lazy reports lose XP. Beautiful ones go viral.

Reputation that ships

Public hunter profiles at bugarena.com/u/yourname — verified finds, skill rankings, and badges that recruiters actually trust.

Sponsored arenas

Companies drop pre-release builds for crowd QA. You hunt, they ship. Top finders get cash bounties and recruiter pings.

// Featured Arenas

Drop in. Break things.
