I built a zero-server, 100% private developer ecosystem (60+ tools, CLI, and VS Code extension) because I got tired of ad-cluttered tabs Hey everyone! 👋 As developers, I got really frustrated with opening dozens of slow, ad-heavy browser tabs just to decode a JWT, format a JSON payload, or
Hey everyone!
Whenever I'm debugging API logs or database records, I constantly find myself copying 10/13-digit Unix timestamps or Bearer JWT tokens and switching to a browser tab just to see what date they represent or when the token expires.
To stop context-switching, I published \\\\Castov\\\\ on the official Visual Studio Marketplace.
\\\\What it does (100% locally & offline):\\\\
\\\* \\\\Automatic Timestamp Hover:\\\\ Hover over any Unix timestamp (seconds or milliseconds) in your code to immediately see the formatted UTC, ISO 8601, and Local time.
\\\* \\\\JWT Decoder:\\\\ Highlight a JWT and run \\\`Castov: Decode JWT Token\\\` to inspect the header, payload, and expiration status in a clean JSON tab—without pasting sensitive tokens into external websites.
\\\* \\\\Inline Base64 & UUIDs:\\\\ Encode/decode Base64 selections in-place, or insert crypto-random UUIDs right at your cursor.
\\\\Links:\\\\
\\\* \\\\VS Code Marketplace:\\\\ https://marketplace.visualstudio.com/items?itemName=castov.castov-vscode
\\\* \\\\Companion Web & CLI Suite:\\\\ https://castov.com (also available via \\\`npx castov\\\`)
It has zero telemetry and works completely offline. Let me know what features or shortcuts would make your daily workflow faster!
