BrightByte DevKit

A comprehensive suite of developer tools for formatting, encoding, generating passwords and more

BrightByte DevKit puts 7 developer tools — and 20+ chainable operations inside the flagship Data Transformer alone — behind a single toolbar click. No more bookmarking a different website for every JSON formatter, Base64 encoder, or password generator you need. Everything runs locally in your browser. Nothing you paste in is ever sent anywhere. WHY DEVKIT • One plugin instead of a dozen bookmarked sites, half of which show ads next to a textarea • 100% local — every transform runs in your browser; nothing is ever sent to a server • No accounts, no tracking, no analytics • Free, with no upsell tier • Built for real developer workflows, not just a single conversion: chain steps together, verify JWT signatures (not just decode them), catch JSON duplicate-key bugs that JSON.parse silently swallows THE DATA TRANSFORMER The core of DevKit: build a recipe by clicking operations from a searchable, categorized palette, then watch the output update live as you type. Chain as many steps as you want — Base64 Decode into Format JSON into SQL Escape, for example — reorder or remove any step, and get told exactly which step failed and why if one does. Includes: JSON/XML/YAML formatting, JSON linting (catches duplicate keys JSON.parse ignores), JSON/XML minifying, URL/Base64/HTML-entity encode and decode, SQL escaping (MySQL/PostgreSQL) and SQL parameterizing, JWT decode with optional signature verification, MD5/SHA-1/SHA-256/SHA-384/SHA-512 hashing (individually or all at once), text case conversion, regex find-and-replace and match highlighting, side-by-side text diffing, and UUID v4 generation (up to 1000 at once). Structured output gets a real collapsible tree view, not a wall of text — and Diff/Regex steps get their own purpose-built highlighted view. Pop the output into its own window when you need more room. PASSWORD TOOLS Generate cryptographically secure passwords (crypto.getRandomValues, not Math.random) with configurable length and character sets, one click to copy. Optionally keep a local history of what you've generated, with timestamps — nothing leaves your device. CONVERTERS • SQL Parameterizer — paste a concatenated SQL string straight out of your Java/JS/C#/Python source and get back a parameterized query with placeholders, in the style your client expects (:name, ?, or $1/$2/...) • cURL to Code Converter — paste a curl command (e.g. "Copy as cURL" from DevTools) and get a ready-to-run JavaScript fetch, Python requests, or Java HttpClient snippet SECURITY AES-256-GCM encryption via the browser's own Web Crypto API — PBKDF2-HMAC-SHA256 key derivation at 600,000 iterations by default. A wrong passphrase, mismatched Associated Data, or tampered ciphertext fails outright instead of silently returning garbage. Includes an "Advanced" mode for ciphertext from another system (manual salt/IV, raw-key mode) and a built-in explainer for anyone who wants to understand what AES-GCM is actually doing. DATE & TIME A live-updating current-timestamp display plus two-way conversion between Unix timestamps (seconds or milliseconds, auto-detected) and ISO/UTC/local/relative dates. PRIVACY BY DESIGN DevKit requests only the permissions each feature needs, and asks for nothing beyond that — no browsing history, no bookmarks. Every permission is documented in the extension's privacy policy. There is no server component: everything above runs entirely inside your browser.
