I build the toolsyou wish existed.

Hi, I'm Krrish. I make sharp, free, private-by-design developer tools that run entirely in your browser, plus automations that quietly take the boring work off your plate.

About me

Small, fast, honest software, built to be used.

No tracking, no upsells, no accounts. Just the thing you came for, the moment you need it.

The Krrish Army Knife

One pocket-sized toolbox for developers. 20+ utilities, from JWT decoding to cron generation, on the web at tools.krri.sh and in your browser toolbar.

Privacy first

Everything runs client-side. Your data never touches a server.

0+

Tools shipped

And counting. All free.

Automation addict

Agentic workflows, RPA and local LLMs. If a human does it twice, I script it.

Speed obsessed

Instant load, zero bloat, keyboard friendly. Tools should feel like reflexes.

The arsenal

Pick a blade.

Twenty tools, one home. Hover, tilt, open.

Locked-down network? Take the knife with you.

Some companies restrict access to tool websites. The Krrish Developer Tools extension puts the same toolbox inside your browser, so there's no page to unblock.

Don't take my word. Type something.

A mini Army Knife running entirely in your browser. Open the network tab. I'll wait.

Automation

Make the busywork run itself.

Inbox in, documents parsed, apps updated, report out. Hit the button, or poke the bot.

Show me the work

Walk me through the tedious process once. I'll spot what a bot can own.

Connect & think

Robomotion, n8n, local LLMs and agents stitched into one flow.

Ship it

Tested, monitored and handed over, so it keeps working while you don't.

Under the hood

My philosophy, in one terminal.

Got a problem worth automating?

Let's build something sharp together, or grab the toolbox and go.
