In their own words
Mayhem
Mayhem is a security platform for testing code and APIs and assessing software components in a dashboard. Its fuzzing combines AI-powered, network-aware methods with symbolic execution and triage. For code, it generates tests autonomously to find vulnerabilities and supplies a reproduction and backtrace for each defect. Mayhem for API tests for OWASP Top 10 API weaknesses and supports stateful, agentless testing. Dynamic SBOM reachability analysis helps identify which software components are on the attack surface. The platform produces vendor-neutral SARIF reports and real-time notifications, and lists integrations with tools including GitHub, Jenkins, GitLab, Jira, Slack, CircleCI, Azure DevOps, Google Chat and Travis CI. Deployment options include managed SaaS, private cloud and closed-network installation; command-line tools run on macOS, Linux and Windows. The Mayhem for API free plan allows up to 50 scans per month. Paid API plans cost $236 a month, with additional scans, enterprise features and personalized support; a 30-day trial is listed for paid plans.
Onyx Launcher
Onyx Launcher is a free, open-source desktop Minecraft launcher for Windows and Linux. It manages separate instances, imports modpacks and supports Fabric, NeoForge, Forge, Quilt and Vanilla. A built-in Modrinth catalog lets users browse, install and update mods and modpacks, while automatic updates and Java runtime management are included. Onyx can detect, download and isolate Eclipse Temurin Java 8, 17 or 21 as needed. Diagnostic features measure in-game FPS, average frame times and stutters, analyze logs, track memory and garbage-collection pauses, and use Crash Bisect to look for conflicting mods through controlled launches. World Guard creates safety snapshots before risky operations and supports rollbacks. Ghost Mode unloads the launcher window, WebContents and GPU processes from memory when Minecraft starts. Microsoft sign-in uses OAuth Device Flow, and offline mode with custom skins is available. Windows builds are currently unsigned; published SHA-256 checksums can be checked. The MIT-licensed project says it is independent of Microsoft, Mojang Studios and Modrinth.
