ROBOTCRASH
Exploring robotics, automation, and cutting-edge technology.
From encoding Base64 and formatting JSON to generating hashes and secure passwords, converting colors and file sizes, inspecting IP addresses, and testing regular expressions, RobotCrash pairs free hands-on developer tools with practical robotics and AI guides and a richly illustrated museum. Build smarter, ship faster.
Developer & Tech Tools
Free tools for developers and makers — Base64 encoder/decoder, JSON formatter, hash generator, color converter, file size converter, IP address lookup, password generator, and regex tester.
🔁 Base64 Encoder / Decoder
Encode text to Base64 or decode it back, fully UTF-8 safe so accents, CJK, and emoji round-trip cleanly — all in your browser
✨ JSON Formatter
Beautify, validate, or minify JSON with 2- or 4-space indentation, and get a clear error message the moment the input is malformed
🔐 Hash Generator
Compute MD5, SHA-1, SHA-256, and SHA-512 digests of any text at once, locally with the Web Crypto API — for checksums and fingerprints
🎨 Color Converter
Convert a color between HEX, RGB, and HSL and preview a live swatch — paste any format and get the other two instantly
📦 File Size Converter
Convert file sizes across decimal (KB/MB/GB/TB) and binary (KiB/MiB/GiB/TiB) units side by side, with the exact byte count
🌐 IP Address Lookup
Validate and classify any IPv4 or IPv6 address — version, class, and private/loopback/link-local/multicast flags — with no external calls
🔑 Password Generator
Generate strong, random passwords with your choice of length and character sets, built on crypto.getRandomValues — nothing leaves the page
🔎 Regex Tester
Test JavaScript regular expressions against any string, toggle the g/i/m/s flags, and list every match with its index and capture groups
Robots & AI Museum
Wander an immersive museum of the ideas and engineering that power modern technology — robotics and autonomous systems alongside artificial intelligence and machine learning, the world of automation and control, sensors and perception, and computing and connected devices, each in its own gallery, so you can get to know the foundations behind every intelligent machine: how each one works, what makes it matter, and the role it plays in shaping the way we build, move, and automate the world.
Tour the museum →From the Journal
Fresh guides on robotics and autonomous systems, artificial intelligence and machine learning, automation and control, sensors and perception, and computing and connected devices, plus practical tips for building and shipping smarter machines.
