CodeCraft – Developer Toolbox for macOS
Stop juggling browser tabs and random scripts. CodeCraft puts 50+ essential developer tools in one fast, native macOS app — always a click away.
Formatters & Beautifiers
Clean up messy code instantly. Format JSON, HTML, XML, CSS, SCSS, LESS, JavaScript, SQL, and YAML with customizable indentation. Minify for
production or beautify for readability. Preview Markdown and HTML live as you type.
Encoders & Decoders
Encode and decode Base64, URL strings, and HTML entities in real time. Decode JWT tokens to inspect headers and payloads. Convert images to Base64
data URIs. Decode PEM certificates. Compress and decompress with GZip. Escape and unescape backslash sequences.
Converters
Convert between JSON and YAML, CSV and JSON, or TOML and JSON — bidirectionally. Parse dates across formats and time zones with a visual calendar and
analog clock. Convert numbers between binary, octal, decimal, and hexadecimal. Calculate CIDR subnets, network ranges, and masks. Parse cron
expressions into plain English with upcoming run times.
Generators
Generate QR codes and read them from images. Create MD5, SHA-1, SHA-256, and SHA-512 hashes. Generate UUIDs in bulk with formatting options. Merge
images and PDFs into a single document. Create placeholder images with custom dimensions, colors, and text.
Text Tools
Inspect text with 14 case conversions and detailed character, word, and line statistics. Test regular expressions with highlighted matches and
capture groups. Generate Lorem Ipsum placeholder text. Compare texts side by side with a Myers diff algorithm — by character, word, or line. Query
JSON with JSONPath expressions. Convert CSV to formatted Markdown tables. Validate JSON against schemas. Explore files in hex view. Browse JSON as a
collapsible, color-coded tree.
Color Tools
Pick colors in 10 formats including HEX, RGB, HSL, and SwiftUI. Use the system eyedropper to sample any color on screen. Generate harmonious color
palettes — complementary, triadic, analogous, and more. Simulate 8 types of color vision deficiency to test accessibility.
JSON to Model
Paste JSON, get production-ready model code. Generate structs and classes for Swift, Kotlin, Java, Dart, C#, Python, TypeScript, and Go — with proper
type inference, nested object support, and language-specific conventions.
