TrenTyx

TrenTyx collects the small utilities developers reach for several times a day and runs all of them client-side, so that inputs such as JWTs, SQL queries and API payloads are never transmitted anywhere.

There are 24 tools across four groups. Data converters handle JSON to and from CSV, YAML and XML, JSON to TypeScript interfaces, structural JSON diffing, CSV to SQL inserts and image to Base64. Text and encoding covers JSON formatting and validation, Base64, URL encoding, Markdown to HTML, case conversion, text diffing and SQL formatting. Dev utilities include timestamps, UUIDs, hashes, password generation, JWT decoding, regex testing, cron expressions, number bases and LLM token counting. Design currently holds a colour format converter.

Each page also explains the format it works with, so the tool teaches as well as converts. Every tool exposes itself through WebMCP for AI agents driving the browser, and each page works offline once loaded
