Hi Product Hunt, Zellio.io is back. If you missed the first launch: it's a set of free tools for the small jobs that come up all day, like formatting JSON, testing a regex, compressing an image, stripping a PDF's metadata or querying a CSV with SQL. Every tool runs in your browser, so the files and text you work on never reach a server. There's no sign-up, and ads keep it free. What's changed since then: each tool used to stand alone, and most real jobs take more than one. This update is about making them work together: • Recipes: 13 multi-step jobs, each on its own page. Paste once, run, and read every intermediate result. • Workflow builder: chain any of 43 operations yourself, then share the chain as a link or a JSON file. The link carries the steps, never your data. • Batch: one operation over up to 50 files, out as a single ZIP. The image resizer does bulk now too, and remembers the custom sizes you save as presets. • Projects: keep a job's files, saved tool settings and bookmarks together on your device, and export the lot as one bundle, password-protected if you like. Also new: 15 tools, including a PNG-to-SVG vectoriser, a palette extractor with a WCAG and APCA contrast matrix, an SVG optimiser, a sensitive-data scanner for logs and an HTML/CSS playground. And for learning: 87 puzzles across regex golf, cron and SQL, plus step-through simulators for OAuth, DNS/TCP/TLS and AES/SHA-256. What it deliberately doesn't do: accounts, sync, or AI that needs your data on a server. The one tool that has to call out, What Is My IP, says so on its page. Which everyday job would you turn into the next recipe?
