Games

2048 Game

Classic 2048. Arrow keys or swipe to slide and merge equal numbers. Each valid move spawns a tile; score accumulates from merges. 4×4 / 5×5 / 6×6 boards, pick a goal tile.

Finance

Bitcoin Address Generator

Generate Bitcoin addresses from private keys for different address types

Security

Env File Secret Rotation Planner

Paste a .env file and get a staged secret-rotation plan. Detects database URLs, API keys, auth tokens, private keys, cloud credentials, payment keys and encryption secrets, scores each by exposure and age, and schedules them across a 4-week rotation timeline with a dual-key checklist and a generated .env.example. Optional last-rotated dates and a configurable cadence (30/90/180/365 days) drive compliance scoring.

Data Processing

.env Parser

Extract and validate .env style KEY=VALUE configurations with detection of duplicate keys and suspicious spaces/quotes

Development

Environment Config Diff Visualizer

Compare dev, staging, and production configuration bundles across JSON, YAML, TOML, or ENV formats and highlight drift, missing keys, and cleanup suggestions

Data Processing

Invert By

Invert keys grouped by values using lodash _.invertBy

Data Processing

Invert Object

Invert keys and values using lodash _.invert

Data Processing

JSON Key Extractor

Extract all keys from JSON objects with multiple output formats. Perfect for analyzing JSON structure, documentation generation, and understanding complex nested objects.

Data Processing

JSON Key Renamer

Batch rename JSON object keys with support for patterns, rules, and transformations. Perfect for API response formatting and data normalization.

Security

JWK Generator & Parser

Generate JSON Web Keys (JWK) for RSA, EC (P-256/P-384/P-521/secp256k1), and OKP (Ed25519/Ed448/X25519/X448), or parse an existing JWK to inspect its parameters, thumbprint, and metadata

Security

JWT Inspector & Verifier

Decode a JWT (header + payload) with syntax highlighting, diagnose standard claims, and verify the signature with HS*/RS*/PS*/ES*/EdDSA keys — plus a tampered-token forgery demo

Data Processing

Keys In List

List own and inherited keys using lodash _.keysIn

Data Processing

Keys List

List own enumerable keys using lodash _.keys

Development

package.json Dependency Auditor

Audit a package.json for dependency hygiene, version-range quality, and optionally inspect a transitive dependency tree from package-lock.json or yarn.lock. Flags duplicates, wildcard or pre-release specs, unsorted keys, missing metadata, and misclassified runtime/dev dependencies.

Security

RSA Encrypt / Decrypt

Encrypt text with an RSA public key or decrypt ciphertext with the matching private key, using OAEP padding (SHA-1 or SHA-256). Handles long messages by chunking. Keys and data stay local. PKCS#1 v1.5 is intentionally not offered (Node disables it for decryption due to Bleichenbacher attacks).

Security

SSH Key Pair Generator

Generate an SSH key pair (Ed25519 recommended, RSA 4096, or ECDSA P-256) with an OpenSSH-format public key ready for ~/.ssh/authorized_keys, a SHA256 fingerprint, and a PEM private key. Optional passphrase encryption. Runs locally.

Data Processing

Zip Object

Create an object from keys and values using lodash _.zipObject
