SVG Viewer is part of DevStudio — a free, in-browser collection of developer utilities that work without sign-up, installation, or any backend service. Drop or paste SVG markup and see a live preview plus declared width / height / viewBox / element-count metadata, 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 SVG Viewer 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 Diff Viewer, Markdown Previewer, Regex Tester, and the rest of the DevStudio toolkit for related developer workflows.
