oriz·dev
A free developer multitool — JSON, base64, JWT, UUID, cron, hash, diff, regex — that runs 100% in your browser.
What it is
oriz·dev is a keyboard-first terminal for everyday developer chores: ten tools on one page, no servers involved.
Paste something, pick a tool with keys 0–9, get output instantly. This page is the
info / about page — the actual tool lives at dev.oriz.in.
Key features
- JSON — format, validate, minify
- Base64 — UTF-8-safe encode / decode
- JWT — decode header + payload, check expiry (secret never sent)
- URL — encode / decode components
- UUID — crypto v4, bulk generate
- Timestamp — epoch ⇄ ISO ⇄ local, live clock, relative time
- Cron — explain a 5-field schedule in plain English
- Hash — SHA-1/256/384/512 over text or a dropped file
- Diff — line-level LCS diff with +/- stats
- Regex — live tester + AI-generate from a description
How it works
- Client-only Astro — static site, small React 19 islands, Tailwind v4.
- AI via g4f — optional polish through
@chirag127/oz-ai(wraps g4f / gpt4free, multi-provider failover, no API key). - PWA-installable — install it from a supporting browser for app-like, offline-capable use.
- 100% in-browser — no upload, no signup, no key. Native APIs (
crypto.subtle,JSON.parse,Intl,RegExp) do the work locally.
