The Backstory Every developer knows the pain: You’re debugging something simple… and suddenly you have 10 tabs open — JSON formatter, JWT decoder, Base64, timestamps, YAML converter, regex tester… I got tired of this routine, so I built the toolbox I always wished existed. What is Spoold? Spoold is a privacy-first, browser-based developer toolkit with 40+ tools, designed to reduce friction in everyday engineering work. Everything runs fully client-side — nothing is sent to any server. No ads. No sign-ups. No tracking. Just tools. What It Can Do Spoold includes 40+ instant tools: JSON formatter & validator JWT decoder Base64 / Hex / Binary converters Regex tester UUID & hashing tools CSV viewer Markdown / HTML preview Unix time & date tools curl → code converter Diff tools QR generator URL shortener Flow Canvas (easy drag-drop diagrams) Encoders, unescape utilities, data inspectors Paste anything — JSON, JWT, curl, timestamps — and Spoold opens the right tool automatically. Why Developers Use It 100% client-side processing (privacy-safe) 40+ tools in one place Instant load time Zero friction UI No ads, pop-ups, or login walls Built for speed and daily workflows A friend once messaged me: “No tool or AI agent could unescape this giant JSON, but Spoold did.” Another said Flow Canvas is “the easiest diagram tool for discussions.” Feedback like that kept this project moving. Who It’s For Backend engineers Frontend developers DevOps engineers Security engineers QA / testers Students Anyone dealing with messy data If you touch JSON or tokens daily… this is for you.
