About HashKit

Our Mission

HashKit provides free, fast, and privacy-focused developer tools. We believe that essential development utilities should be accessible to everyone without requiring signups, subscriptions, or sending your data to third-party servers.

Privacy First

Every tool on HashKit runs entirely in your browser. Your data never leaves your device. Whether you're formatting sensitive JSON, decoding JWTs with authentication tokens, or generating hashes — everything is processed locally on your machine.

Built for Developers

We've curated a collection of tools that developers use daily:

• Encoders & Decoders — Base64, URL encoding, JWT tokens
• Formatters — JSON formatting and validation
• Generators — UUIDs, hashes, placeholder text
• Converters — Colors, timestamps, markdown
• Testing Tools — Regex tester with live matching

No Account Required

Just open the tool you need and start using it. No signup forms, no email verification, no premium tiers. All tools are completely free and always will be.

Open & Transparent

HashKit is supported by non-intrusive advertising. This allows us to keep all tools free while maintaining and improving the platform. We don't sell your data because we don't collect it in the first place.
