As answered by people managing CodeSandbox and ForgePlug.
ForgePlug's answer:
ForgePlug puts 70+ everyday tools (PDF, image, developer, finance, SEO, writing, health, QR/barcode and more) in one place, and most of them run 100% in your browser, so files never leave your device. Core tools are completely free with no signup, no watermarks and no artificial daily or file limits, including batch processing that competitors usually keep behind a paywall.

ForgePlug's answer:
Students, freelancers, developers, small-business owners and everyday internet users who need to get a quick task done, like compressing a PDF, formatting JSON, making an invoice or generating a QR code, without installing software, creating an account or paying for a subscription.
ForgePlug's answer:
ForgePlug was started by an independent developer from India with 10+ years in the IT industry. After repeatedly running into "free" online tools that forced signups, added watermarks, capped files or uploaded private documents to unknown servers, the goal became simple: build one place with genuinely free, privacy-first tools that run in the browser. ForgePlug is built and maintained solo, with new tools added regularly based on what people actually search for and ask for.
