Tools

Minimal, fast developer tools that run entirely in your browser. No data is ever sent to a server.

.env Parser

Splits dotenv content into a key/value table, flags invalid lines, and masks values of sensitive keys such as secret, token and password. Runs in your browser.

Tool

Backoff & Jitter Calculator

Compute an exponential backoff schedule and see how full, equal, and decorrelated jitter spread the retries. Client-side, nothing is retried.

Tool

Base64 Encoder / Decoder

Encode and decode text as Base64, with a URL-safe variant and full UTF-8 support. Runs in your browser; your text is never sent anywhere.

Tool

Code Image Generator

Turn a code block into a shareable PNG. The code itself never leaves your browser; pick a theme, export scale, and window chrome.

Tool

gitignore Generator

Generate a .gitignore from your project folder. Unlike the competition, nothing is uploaded — not even the file names ever leave the page.

Tool

HTTP Status Codes Reference

What common HTTP status codes mean and where each shows up. Search by code, name or keyword. Runs in your browser; nothing you type is sent anywhere.

Tool

JSON Formatter

Format JSON with 2-space, 4-space or tab indentation, or minify it; invalid JSON gets an error message. Runs in your browser; your data never leaves it.

Tool

JSON Schema Backward-Compatibility Diff

Diff two JSON Schemas: is the change backward-compatible, or a breaking one that needs a new message version? Runs in your browser.

Tool

JWT Decoder

Decodes a JWT header and payload and shows the exp and iat claims as ISO timestamps. It does not verify the signature; the token stays in your browser.

Tool

Password Generator

Cryptographically secure password generator: set the length and character classes, and optionally exclude look-alike and shell characters. Runs in your browser.

Tool

Typing Speed Test

Measures Turkish and English typing speed honestly: CPM is the primary metric, and a code mode exercises real brackets and template syntax.

Tool

Unix Timestamp Converter

Convert both ways between Unix timestamp and ISO 8601. Seconds and milliseconds are auto-detected; shows UTC, local and relative time. Runs in your browser.

Tool

URL Parser

Breaks a URL into protocol, host, port, pathname, hash and credentials, and lists its query parameters in a table. Runs in your browser; the URL stays there.

Tool

UUID Generator (v4 & v7)

Generates UUID v4 (random) and v7 (time-ordered, RFC 9562), one at a time or in bulk. Runs in your browser with the Web Crypto API; nothing is sent anywhere.
