DevOps Debugger is part of DevStudio — a free, in-browser collection of developer utilities that work without sign-up, installation, or any backend service. CI-script Docker debugger — workspace mount + GHA / GitLab / CircleCI YAML parser + job/step tree + gateway-internal ci_replica session start (step-through + breakpoints land in WIN76), all running entirely on your device. Because the page never uploads what you paste, you can run sensitive payloads, configuration files, secrets, or production data through it with confidence: nothing leaves your browser tab. Use DevOps Debugger for ad-hoc debugging, code review, log triage, release prep, learning a new format, or as a quick scratchpad while you build. If you use this tool a lot, pair it with Code Navigator, AI Agent Runtime, Diagram Designer, and the rest of the DevStudio toolkit for related developer workflows.
