Paste minified or single-line JSON to instantly validate, pretty-print, or compress it — handles deeply nested objects, arrays, and escaped strings entirely in your browser, no upload required.

Clean up cramped, single-line, or ORM-generated SQL into properly indented queries — handy before a code review, when sharing a query in a PR, or pasting into documentation.

Generate RFC 9562-compliant UUIDs in bulk — random v4, time-ordered v7 for sortable primary keys, or legacy v1 — ready to copy straight into seed data or test fixtures.

Generate ULIDs in bulk — a UUID alternative with a built-in millisecond timestamp, so records sort chronologically by ID alone. Useful for primary keys, event logs, or anywhere insertion order matters.

Generate strong random passwords with custom length and character sets — useful for one-off secrets like a new account sign-up or a server config, when you need a password now rather than reaching for a password manager.

Generate random API keys and secret tokens for local development, MCP servers, or test fixtures — pick the length and character set, then drop the result straight into a `.env` file or mock config.

Percent-encode or decode URLs, query parameters, and special characters — handy for debugging broken links, building query strings by hand, or inspecting an encoded parameter you received from an API.

Convert between Unix epoch time (seconds or milliseconds) and human-readable dates in any timezone — handy for decoding a timestamp buried in a log file or an API response without doing the math yourself.

Enter an IP address and CIDR prefix to instantly get the network address, broadcast address, subnet mask, and usable host range — useful when planning a subnet or double-checking a firewall rule.

Paste two versions of text, code, or config and see exactly what was added, removed, or changed, highlighted line by line — handy for reviewing a config diff or comparing pasted snippets outside of git.

Preview an SVG file and export it as a PNG — useful when a tool or platform doesn't accept vector graphics and you need a raster version of an icon or logo without opening a design app.

Compare hex or RGB color codes side by side and generate a gradient between two colors — useful for exploring a palette or previewing a CSS gradient before writing the code.
