Onyx Pro

Onyx Pro is a lightweight desktop utility built for developers who want to properly evaluate AI-powered IDEs before committing to a subscription. Instead of being limited to a one-time trial or rushed onboarding experience, Onyx Pro lets you reset trial-related state locally so you can re-test tools like Cursor, Windsurf, Warp, and others under real working conditions.

The idea is simple. Choosing an AI IDE is not something you should decide in a single session. You need time to experiment, revisit features, and see how each tool actually fits into your workflow. Onyx Pro gives you that flexibility without sending any of your data off your machine.

What It Does

At its core, Onyx Pro resets the local trial state of supported AI IDEs. That means you can restart onboarding flows, re-run evaluations, and test features again as if you were using the tool for the first time, without manually clearing files or reinstalling anything.

Everything runs locally, so your code, prompts, and project files stay exactly where they belong, on your machine.

Key Features

Local-first and privacy-safe
All reset operations happen on your device. Nothing gets uploaded or processed in the cloud, which makes it safe to use with real projects and sensitive code.

One tool, multiple IDEs
Onyx Pro supports seven AI environments including Cursor, Windsurf, Warp, Kiro, Trae, Antigravity, and Codex, so you can evaluate them all from a single place.

No more manual cleanup
Instead of digging through hidden folders or reinstalling apps, you can reset trial-related state in a few clicks.

Repeatable testing
You can revisit tools multiple times, test new features after updates, or compare IDEs side by side under consistent conditions.

Clear and predictable behavior
When you run a reset, Onyx Pro tells you exactly what will happen, like signing you out or clearing onboarding data, so there are no surprises.

Works on common dev setups
Available for Windows 10 and 11, as well as Debian-based Linux systems.

Simple pricing with no subscriptions
Pay once for a time window or lifetime access and use the tool as needed with no recurring billing.

When You Would Use It

Trying multiple AI IDEs before choosing one
Compare tools like Cursor and Windsurf using your actual projects instead of demos.

Re-testing after updates
AI IDEs evolve quickly. Onyx Pro lets you revisit them when new features are released.

Making a confident purchase decision
Spend more time evaluating instead of rushing before a trial expires.

Avoiding tedious setup work
Skip the manual process of clearing caches or reinstalling apps.

What Makes It Different

It is built for real workflows
Onyx Pro is not about extending trials for the sake of it. It is about giving you enough room to make an informed decision using your actual development setup.

Everything stays local
No accounts, no cloud dependency, and no data leaving your machine. This matters when you are working with private code.

One consistent experience across tools
Instead of figuring out different reset methods for each IDE, you get a single and predictable workflow.

Independent and unbiased
Onyx Pro is not tied to any IDE vendor, so you can evaluate tools on your own terms.

Bottom Line

Onyx Pro helps you slow down the decision-making process in a space that usually pushes you to rush. By letting you reset and re-test AI IDEs locally, it turns a one-time trial into something you can actually learn from, so when you do commit, you know it is the right tool for your workflow.
