A carefully crafted family of developer tools — browser extensions, component libraries, and utilities — built to make your workflow faster, smarter, and more efficient. All free.
From browser extensions that give you superpowers in the DevTools to React component libraries — everything is free and built with quality in mind.
Let your AI agent test in the browser you're already signed into.
An MCP server plus browser extension that lets AI coding agents drive your already-open, already-authenticated browser tab — running real QA flows, assertions, and visual comparisons without ever launching a fresh browser or re-logging in.
Beautiful React components, zero compromise.
A modern React component library built for developers who care about design quality, accessibility, and developer experience. Free to use in any project.
Supercharge your Jira workflow.
A powerful browser extension that extends Jira with worklog management, time tracking, sprint reports, and productivity tools that Jira doesn't provide out of the box.
A fast, tiny batch image studio for your desktop.
Resize, convert, optimize, annotate and compare images in bulk — building a full matrix of sizes × formats from any files or folders. Native Rust speed in an ~8 MB app, fully offline.
Track every source. Know every change.
SourceTraq is your go-to tool for analyzing pull request trends, activities, and commit histories across multiple code repositories.
The developer's browser command center.
Rule-based HTTP request interception, tab control, storage inspection, security analysis, and in-page developer tools — all in one browser extension.
None of our tools collect your data. What stays on your device, stays on your device. Always.
Every product in the utilsware family is free — for personal use, for commercial use, for any use. That's a commitment, not a promotion.
Developer tools should disappear into your workflow. We obsess over performance so our tools never slow you down.
One developer, deliberate choices. Every feature in every product earns its place. No bloat, no filler.
All products are built and maintained by a single developer. If these tools save you time, consider showing some support.
