API & Web Utilities for Developers
Generate UUIDs and hashes, test regular expressions, decode cron schedules, convert timestamps, preview markdown and format SQL — the small jobs you do every day, done instantly and privately.
Developer tools
Pick a tool to open it. Everything runs locally — no servers, no tracking of your input.
About Codeora
A focused lab of API and web utilities, built for working developers.
Built for the daily grind
Codeora covers the in-between jobs of API and web work: minting IDs, hashing payloads, sanity-checking regex before it ships, and reading a cron schedule without a cheat sheet.
Private by design
Every tool runs entirely in your browser using built-in platform APIs like Web Crypto. The text, tokens and queries you paste in are never uploaded, logged or shared.
Fast and free
No accounts, no paywalls, no waiting on a server round-trip. Open a tool, paste your input, get the answer — on desktop or mobile, in light or dark mode.
