Free developer tools

Everyday utilities

TechVentry tools help with small jobs that come up every day in development: formatting payloads, decoding tokens, testing patterns, and converting data types.

Format JSON, decode JWT headers and payloads, test regular expressions with live matches, convert Unix timestamps, and generate UUID v4 identifiers in seconds.

Private in your browser

You can also preview Markdown with styled output, beautify SQL queries, compare two texts line by line, convert colors between HEX and RGB, and build TypeScript interfaces from JSON samples.

All tools run in your browser. Your input stays on your device, which is safer for auth tokens, API keys, and private customer data during debugging sessions.

Guides on each tool

Nothing is uploaded to our servers for these utilities. That design choice matters when you work with production credentials or regulated data on shared machines.

Each tool page includes a short guide with concepts, usage tips, common mistakes, and links to related articles when you want deeper context.

When to use them

Developers use these tools during API integration, incident response, code review, and technical writing when a full IDE setup is overkill.

Open the tool you need from the grid above, or browse the full list from the tools menu anytime you need a quick utility without installing software.
