DataBench – Browser Data Workbench

What it does

DataBench is a free browser-based workbench for developers and data people. Format JSON, convert CSV, generate SQL, test Regex, encode Base64, preview Markdown, convert timestamps, and more — 25+ tools in one fast tab. Everything runs 100% client-side. No installs, no sign-up, no server. Your data never leaves your machine. Stop juggling bookmarks across slow, ad-heavy sites. Open DataBench, get it done.

Free online tools for JSON, CSV, SQL, XML, YAML, images, PDFs, and more. Everything runs in your browser, no signup needed.

// Stop pasting sensitive data into random sites. // 30 tools. Client-side. Nothing leaves your machine. Open any tool and paste text or drop a file. No account, no upload step, no waiting on a server to accept the request. Formatting, validation, and conversion all happen locally with JavaScript. Your data never leaves the tab it's typed into. Grab the result and go. Nothing is stored on our end, so there's nothing left behind once you're done. What actually happens to your data on server-side "free" tools, and why that's a problem for API keys and exports. The syntax errors that trip people up most often, and how to catch them before they reach production. Patterns, flags, and capture…from databench.netlify.app

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself.

  Homebrew 6.0.0▲1,481

  Today, I’m proud to announce Homebrew 6.0.0. The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!

  Performative-UI – A react component library of design tropes▲1,181

  Hi HN! I was super frustrated at apps like tiktok and wechat preventing me from saving or downloading the animated gifs, so I made a little tool to turn a screen recording into a slack-sized emoji. Hope you get some value from this!
