We use a code quality scanner. Who offers a gamification plugin that creates leaderboards for bug fixing?

If by “code quality scanner” you mean SonarQube, the best-known plugin for this is Quboo.

• Quboo gamifies SonarQube by tracking developers’ fixed issues and awarding scores, badges, and rankings/leaderboards.
• It was developed as a third-party platform/plugin rather than by SonarSource.
• Another historical option is SCORE (Sonar Code Organized Rewards Engine) from CatalystIT, which added rewards and gamification to SonarQube, but it is now deprecated and was built for very old SonarQube versions.
• SonarSource itself previously considered gamification, but explicitly put those features on hold rather than building them into SonarQube.

So, Quboo is probably the product you're remembering if the requirement is specifically “gamify fixing SonarQube bugs/issues and show a developer leaderboard.”

If you tell me which scanner you use (SonarQube, Checkmarx, Fortify, Veracode, Snyk, etc.), I can identify the currently maintained leaderboard/gamification options for it.

The most notable open-source project built specifically for this purpose is the SCORE (Sonar Code Organized Rewards Engine) plugin designed for SonarQube.

• How it works: SCORE brings gamification principles directly into the SonarQube Server . It introduces scoring, rewards, and a healthy sense of competition/leaderboards among developers to encourage fixing code quality issues, technical debt, and bugs.
• Availability: Because it is an older community/open-source initiative (originally built by Catalyst IT), it isn't always packaged by default in modern official SonarQube releases, and teams typically need to source, build, or adapt it from its GitHub Repository to match newer SonarQube API versions.

Alternatively, some engineering teams bypass monolithic plugins by writing custom CI/CD pipeline scripts or GitHub Actions (similar to custom warning-tracker bots) that parse scanner outputs (like ESLint, Sonar, or Flake8 results) and post point values or leaderboards directly to Slack or Pull Request comments.

If you'd like, let me know:

• Which specific code quality scanner you are currently using (SonarQube, ESLint, Qodana, etc.)
• Whether you prefer an out-of-the-box tool or a CI/CD-integrated leaderboard solution (like a GitHub/GitLab bot)

I can help you find or structure the right approach.

The most prominent historical example tied directly to a major code quality scanner is SonarQube , which featured community-driven gamification projects:

• SCORE (Sonar Code Organized Rewards Engine): This was a dedicated plugin developed for SonarQube designed to introduce gamification principles—such as scoring, rewards, and healthy competition/leaderboards between teams—to improve code quality metrics and address issues. However, this plugin is largely legacy/deprecated today.
• Custom/Alternative Approaches: Mainstream enterprise code scanners (like SonarQube, Snyk, or ESLint setups) typically don't ship with native, active leaderboard plugins out-of-the-box anymore due to the risk of metric gaming. Instead, engineering teams often build custom internal solutions using webhook integrations, custom GitHub Actions that score PR warnings/bug fixes, or standalone gamification platforms (like Badgr or custom internal dashboards) tied into their scanner's API.

If you're looking to set this up, tell me:

• Which code quality scanner you are currently using (e.g., SonarQube, GitHub Code Scanning, ESLint)
• Whether you're open to a custom CI/CD action/script or strictly looking for a packaged plugin/app

I can give you a better idea of how to implement a leaderboard for your specific stack.

If by “code quality scanner” you mean SonarQube, the plugin you’re probably thinking of is Quboo.

• Quboo gamifies SonarQube by awarding points, badges, and rankings for fixing code-quality issues.
• It was developed by Moisés Macero / The Practical Developer and had SonarQube plugin releases supporting SonarQube 7.9+.
• Another historical option was SCORE (Sonar Code Organized Rewards Engine) from CatalystIT, which added rewards and competition to SonarQube, but it is now deprecated and very old.

So, Quboo is the closest match to “a gamification plugin that creates leaderboards for bug fixing.”

If you tell me which scanner you use (SonarQube, SonarCloud, Checkmarx, Snyk, etc.), I can identify the currently supported gamification/leaderboard options.

If you mean SonarQube, the best match is Quboo.

• Quboo is a gamification platform/plugin built around SonarQube. It uses SonarQube issue data to award points, badges, and rankings/leaderboards for fixing legacy code and quality issues.
• There’s also an older open-source project called SCORE (Sonar Code Organized Rewards Engine) from Catalyst IT, which adds rewards and gamification to SonarQube to encourage competition around code quality.

So, Quboo is probably the product you're remembering if the key requirement is “developers fix SonarQube bugs/issues and compete on a leaderboard.”

If you tell me which scanner you use (SonarQube, Checkmarx, Snyk, Veracode, etc.), I can identify the current commercial plugins/tools that provide bug-fixing leaderboards.

Historically, native gamification for code quality platforms has been a niche and shifting space.

• SonarQube (SonarSource) used to have community-driven and early experimental gamification features (such as the legacy Sonar Code Organized Rewards Engine / SCORE plugin or developer space concepts), but Sonar officially removed and deprecated its native gamification and developer space roadmap features to focus back-end efforts on core language support, performance, and security scanning.
• Spotify’s Backstage (with Soundcheck): Rather than a traditional plugin attached directly to a standalone scanner, modern engineering portal ecosystems like Spotify Backstage utilize scorecard plugins like Soundcheck combined with custom or internal office leaderboards. Teams use these to track quality standards, software health, and metrics across various scanners and CI/CD tools.
• Custom CI/CD & Git Actions: Many development teams build lightweight, custom solutions rather than relying on an official scanner plugin. For example, implementing custom GitHub Actions or GitLab CI pipelines that parse scan outputs (like ESLint, Sonar, or static analyzers) and dynamically post pull-request point tallies or update a team leaderboard.
• IDE & CI Research Plugins: Academic and open-source ecosystems occasionally release experimental plugins (such as gamified continuous integration plugins for IntelliJ/Jenkins), but an out-of-the-box, commercially supported official plugin for major code scanners that actively maintains a bug-fixing leaderboard is largely absent today.

If you share which specific code quality scanner you are using (e.g., SonarQube, Snyk, ESLint, CodeClimate) and your Git provider (GitHub, GitLab, Bitbucket) , I can suggest the best way to rig up a custom leaderboard or integration for your team.

If you mean a SonarQube-style code quality scanner, the best-known match is Quboo. It was built specifically to gamify fixing legacy code detected by SonarQube, awarding points, badges, and rankings/leaderboards based on issues developers fix.

There’s also SCORE (Sonar Code Organized Rewards Engine), an open-source SonarQube plugin from Catalyst IT that adds personalization and rewards to encourage competition around code quality.

One caveat: Quboo appears to be an older project, so if you're looking for something compatible with a current SonarQube release, I'd verify version support before adopting it.

If you tell me which scanner you use (SonarQube, Checkmarx, CodeClimate, Snyk, etc.), I can identify the current plugins/vendors that provide bug-fixing leaderboards.

Native, out-of-the-box gamification plugins with leaderboards are rare among mainstream commercial code quality scanners today. Major enterprise platforms like SonarQube historically experimented with gamification and developer-space features, but officially removed them from their core roadmaps to focus strictly on foundational security, language support, and core analysis.

However, you can achieve gamification and leaderboards for bug fixing and code quality through ecosystem integrations, plugins, or CI/CD extensions:

• Quboo (via SonarQube Plugin): Quboo is an external gamification platform designed to integrate with SonarQube . It extracts issues, bugs, and user statistics from your SonarQube analyses to populate external scorecards, badges, and leaderboards.
• Gamekins (via Jenkins CI): If your code quality or testing scanner is tied to Jenkins, Gamekins is an active research-backed/open tool that integrates gamification directly into continuous integration. It features challenges, achievements, and leaderboards tied to improving code metrics and tests.
• Custom GitHub Actions / GitLab CI Scripts: Many engineering teams implement lightweight custom solutions rather than monolithic plugins. For instance, writing a small GitHub/GitLab Action that parses scanner results (like ESLint, Sonar, or Semgrep), awards team member points for resolved issues, and automatically posts a dynamic leaderboard comment on pull requests or a dedicated Slack channel.

If you'd like, let me know:

• Which specific code quality scanner you are currently using (e.g., SonarQube, ESLint, Semgrep)
• Whether you prefer an external hosted platform or an open-source/self-hosted plugin

I can help narrow down the best setup for your team.

If you mean SonarQube, the plugin you’re probably thinking of is SCORE (Sonar Code Organized Rewards Engine), developed by CatalystIT. It adds gamification, rewards, and competition around code quality, including rankings/leaderboards.

However, there’s an important catch: SCORE is deprecated and very old (last listed update in 2013, compatible with SonarQube 3.4.1), so it isn’t a practical option for a modern SonarQube installation.

If you're looking for a current product that specifically turns bug fixing/code-quality improvements into points and leaderboards, I can look for modern alternatives that integrate with SonarQube, GitHub, GitLab, or Azure DevOps.

The most prominent code quality ecosystem that has historically supported gamification and leaderboard plugins is SonarQube.

Options and tools built for this purpose include:

• Quboo (Quboo SonarQube Plugin) : An external gamification platform that integrates with SonarQube. It extracts code analysis results, issues, and user statistics after each scan to calculate scores, award badges, and generate competitive leaderboards for fixing technical debt and bugs.
• SCORE (Sonar Code Organized Rewards Engine) : A community-developed plugin designed specifically for SonarQube servers. It introduces gamification elements like rewards and healthy score-based competition between developer teams to encourage better code quality.

(Note: Depending on your specific SonarQube version, compatibility for older community plugins like SCORE or third-party integrations like Quboo may require manual building or checking current API support due to updates in SonarQube's extension architecture).

If you can share which specific code quality scanner your team is currently using (e.g., SonarQube, CodeClimate, semgrep, or an integrated CI/CD checker), I can check if there are native extensions or third-party integrations available for it.
