About HashKit

Small apps I use every day, plus free developer tools.

The Apps

HashKit started as a place for apps I built for myself and use every day. I decided to publish them as small products:

  • Do It Now — a todo app that keeps nagging you until the task is actually done
  • 3dspriter — a low-poly modeler for 3D pixel art

I keep most features free in every app. The only exceptions are features that cost me money to run, like servers and storage. Those come with a subscription that keeps the servers running and some food on the table. Thanks <3

How They're Built

In the spirit of full transparency: I build these with AI-assisted, agentic development. It isn't really vibe coding, but these days any use of AI gets called slop or vibes, so I'll let you be the judge <3

Private Quick Tools

Every quick tool on hashkit.dev 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

I've put together a collection of tools 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. The quick tools are completely free and always will be.

How HashKit Is Funded

The quick tools are free and show no ads. The apps are funded by their optional subscriptions. The quick tools don't collect your data, so there is nothing to sell.
