Stop Reinventing the Wheel
As developers, we often find ourselves writing small scripts to do mundane tasks: decoding a Base64 string, parsing a URL, or formatting JSON. These context switches kill productivity.
Karvics provides a dedicated suite of developer utilities designed to save you time.
1. JSON and Data Formats
Working with APIs often means wrestling with JSON.
- JSON to TOON: Convert JSON to Token-Oriented Object Notation for easier analysis.
- TOON Validator: Ensure your data structures are correct and error-free.
2. Encoding and Decoding
Need to debug an authentication header or encode a binary file?
- Base64 Encoder / Decoder: Instantly switch between raw text and Base64 strings.
- URL Analyzer: Decode complex URLs, view query parameters in a clean table, and modify them on the fly.
3. Token Estimation
Building LLM applications? You need to keep an eye on costs.
- Token Count Estimator: Paste your prompt and get an instant estimate of token usage and cost for models like GPT-4 and Claude.
4. Quick Utilities
- QR Code Generator: Generate QR codes for testing mobile deep links or sharing Wi-Fi credentials.
- Online Notepad: A quick scratchpad for pasting logs or code snippets without opening a new file.
5. Dev Tools for Everyday Data Wrangling
- JSON Formatter & Validator: Beautify, minify, or validate JSON, with a collapsible tree view for deeply nested data.
- JWT Decoder & Debugger: Decode a token's header and payload, check expiry, and verify an HS256 signature.
- JSON to CSV Converter: Flatten nested JSON objects into dot-notation columns for spreadsheets.
- Timestamp / Epoch Converter: Smart input auto-detects seconds, milliseconds, or a date string.
- UUID / ULID / NanoID Generator: Generate up to 1000 IDs at once, in whichever format your schema needs.
- YAML ↔ JSON ↔ TOML Converter: Auto-detects the input format and converts to any of the other two.
- Hash Identifier: Not sure if that string is MD5, SHA-256, or bcrypt? This narrows it down instantly.
- Barcode Generator: Create CODE128, EAN, or UPC barcodes for testing checkout flows.
- Mock Data Generator: Generate realistic fake Users, Products, Companies, or Transactions for testing, exportable as JSON, CSV, YAML, TOML, or TOON.
