BeanNest tools
Developer Tools
Format, inspect, convert, and prepare developer data with clear per-tool processing and privacy boundaries.
Base64 Encode & Decode
Encode UTF-8 text to standard Base64 or Base64URL and strictly decode it back to text without sending source content away.
Open tool →URL Encoder & Decoder
Encode or decode URL components and full URLs locally with explicit scope, malformed-percent errors, swap, and copy.
Open tool →UUID v4 Generator
Generate one or up to 500 cryptographically secure UUID v4 values locally with regenerate and copy-all actions.
Open tool →SHA-2 Hash Generator
Generate SHA-256, SHA-384, and SHA-512 fingerprints for local text or bounded local files using browser Web Crypto.
Open tool →Unix Timestamp Converter
Convert explicit Unix seconds or milliseconds to UTC/local/ISO time and convert local or UTC dates back to epoch values.
Open tool →Code Formatter
Format JavaScript, TypeScript, CSS, HTML, Markdown, YAML, and related web languages with Prettier locally in your browser without executing source.
Open tool →JSON Formatter & Validator

Open tool →SQL Formatter
Format SQL for Standard SQL, MySQL, MariaDB, PostgreSQL, SQLite, SQL Server, BigQuery, and Snowflake locally without connecting or executing queries.
Open tool →URL to Markdown
Render a public web page with Cloudflare and convert the readable result to Markdown for copying or download.
Open tool →What to expect
Useful browser results, with the browser limits explained.
BeanNest keeps the main task compact and puts deeper guidance below the work surface. A tool reports what it can actually observe or produce in your browser; it does not claim to certify hardware, formats, or system behavior that the web platform cannot verify.
Clear processing boundaries
Developer tools can be browser-local or use a narrowly scoped Cloudflare service when the job requires remote access. Each tool page says exactly what leaves the browser and what is not stored.
