Hey Product Hunt! 👋

I'm Sourabh, the creator of QADevBench.

I built QADevBench because I was tired of pasting JWTs, API payloads, and test data into random online tools, not knowing where that data was going or whether it was being stored.

QADevBench brings 47 developer and QA tools together in one place, with privacy at its core. All processing happens directly in your browser. No uploads, no accounts, and API Workbench secrets stay in memory only.

Here's what you'll find across 9 categories:

🧾 JSON & YAML: Format, validate, diff, convert, and generate.

🔐 API & Auth: API Testing Workbench with assertions and cURL import, JWT decoder/generator, Basic/Bearer header builders, and cURL generator.

🧪 Testing: Regex, JSONPath, XPath, and CSS selector testers, plus HTTP status reference.

🎲 Test Data: Realistic JSON/CSV records, random user data, UUIDs, and email generators.

📝 Markdown, Encoding & Text: Markdown editor and preview, TOC and table generators, Base64, URL, HTML and Unicode tools, text diff, and case converter.

⚙️ DevOps: Cron tester and generator, timestamp converter, and Docker/Kubernetes YAML helpers.

And one little productivity feature: press ⌘K / Ctrl+K from anywhere to quickly find and jump to any tool.

I'd genuinely love to hear your feedback!

What's one developer or QA tool you wish you had in your daily workflow that isn't already available in QADevBench?

I'm looking for ideas for the next set of tools to build. 🙏
