Every small dev tool you keep googling, in one app.
Devkito puts 122 everyday tools behind one shortcut: formatters, encoders, converters, generators and network checks. They run on your machine, so they work offline and what you paste stays with you.
Free for 7 days, no account needed.
This is the real list from the app. Press Enter to open a tool.
Why developers keep it open
Your data stays on your machine
Tokens, keys and customer data never go through someone else's website. Network tools only contact the host you point them at.
One shortcut away
Press ⌥⌘K from any app to bring Devkito forward with search open. ⌘↵ runs a tool, ⇧⌘C copies the result.
Picks up where you left off
Inputs, favourites and recent tools are remembered between sessions, and you can export your settings to another machine.

Questions
Does Devkito work without an internet connection?
Yes. Every tool except the network ones (DNS, WHOIS, TLS and HTTP requests) runs entirely on your machine. A licence needs to check in once every 30 days.
What happens after the trial?
After 7 days the tools lock until you enter a licence key. Your saved inputs and settings stay where they are.
What happens when my year of updates ends?
Devkito keeps working with every tool you have. You just stop receiving new versions until you renew.
Can I move my licence to a new computer?
Yes. Deactivate it in Settings on the old computer to free a slot, then activate it on the new one.
What does Devkito send over the network?
Licence checks, update checks and, if you leave them on, anonymous crash reports. Crash reports never include what you type into tools, and you can turn them off in Settings.
Stop pasting secrets into random websites.
