About

Free DevOps tools that run entirely in your browser.

OpsCanopy is a growing collection of focused utilities for platform and DevOps engineers. Each one solves a small, real problem — and each one runs 100% client-side, so the things you paste never leave your device.

Why it exists

Engineers reach for quick tools dozens of times a day: validate a workflow file, decode a token, test a regex against log lines, work out a subnet, convert a suppression file. Too many of those tools ask you to paste sensitive internal data into a website that quietly uploads it to a server.

OpsCanopy takes the opposite approach. The tools are fast, free, and private by construction — nothing you paste is ever transmitted, because there is nowhere for it to go.

That includes AI assistants: a chat box is a third party too, and anything you paste into one is retained on a third party’s servers. A tool that computes locally never puts you in that position.

Principles

Local-only by construction. There is no server that could receive your input — privacy here is architecture, not a policy promise.

Deterministic, not plausible. Tools compute their output with real parsers and exact arithmetic instead of predicting likely-looking text.

Free forever, no accounts. No paywall, no signup, no email capture — open a tool and use it.

Open source, so you can audit it. The full code is public on GitHub, and you can read exactly what each tool computes.

How it works

The whole site is static. Every tool is a self-contained program that runs in your browser using JavaScript and, where it helps, WebAssembly. There is no backend, no API, and no account system. Once a page has loaded, most tools keep working even with the network disconnected.

How it’s built and tested

The engines are pure TypeScript. Where correctness has an authority to answer to, the tests are pinned to it — RFC 3021 /31 subnet behaviour, NIST hash test vectors, and a versioned conformance corpus for the GitHub Actions expression tester.

The engines take text in and return results — no network calls, nothing hidden — so the behaviour a tool claims is reproducible in a test.

Who it is for

It is built for platform engineers, SREs, DevOps practitioners, and anyone who lives close to infrastructure — but the tools are useful to any developer who wants a quick, private answer without installing anything.

Who builds it

OpsCanopy is built and maintained by Pushkar Kumar and Asif Khan — engineers who got tired of pasting sensitive config into random web tools and decided to build fast, private, client-side alternatives instead.

Pushkar Kumar — a software developer and DevOps engineer interested in DevOps. He set out to create a free resource for new developers and DevOps engineers learning this path, so DevOps can be easily guided and learned — since when he started, there wasn't a free resource like this to start with.

Asif Khan — a software developer and DevOps engineer interested in DevOps. He set out to create a free resource for new developers and DevOps engineers learning this path, so DevOps can be easily guided and learned — since when he started, there wasn't a free resource like this to start with.

Development happens in the open on GitHub, so you can audit exactly how each tool behaves, report a bug, or suggest the next utility to add.
