The arsenal

Every optimization, one tool.

No sketchy scripts, no 40-tab tutorials. ONYX stages every change, tags it by risk and keeps a full manifest — so nothing is ever a mystery.

ONE CLICK

Apply Recommended

One button stages every Safe tweak plus the functionality-safe Medium ones and runs them with a live progress bar. 870+ tweaks in a single pass — nothing breaks features.

HOME

Memory cleaner

Native standby-list flush, working-set trim and file-cache cleanup with a live result. No external tools, no drivers.

Latency & network

Nagle, TCP profiles, DNS presets, LSO/RSC, interrupt moderation — tuned for ping, repaired when things go sideways.

GPU · CPU · eGPU

Per-card packs for NVIDIA, AMD and Intel — P-states, MSI mode, HAGS, telemetry — plus Thunderbolt and eGPU presets.

Game profiles

Validated setups for Fortnite, CS2, R6 and more — priorities, driver profiles, configs. Process Lasso walkthroughs included.

Storage hub

Deep cleanup of 120+ targets, duplicate finder, large files, space analyzer, startup control, one-click maintenance.

BIOS adviser

Per-board firmware recommendations with step-by-step guidance. VIP only — the deep-locks page for your motherboard.

Free vs VIP

611 tweaks stay locked until you say so.

The free tier is genuinely useful — debloat, privacy, QoL, junk cleaner, app store and tools. VIP opens the full arsenal:

  • All 611 premium performance tweaks (marked ★)
  • The BIOS adviser — per-board firmware guidance
  • The full Storage hub — deep clean, duplicates, analyzer
  • Premium payloads delivered from the licence server, never shipped in the app

FAQ

Before you ask.

Is this safe? Will it break my PC?

Every tweak is tested and risk-tagged (Safe / Medium / Risky), Apply Recommended only uses functionality-safe items, and every change keeps its own revert. You can create a Windows restore point from inside the app before you touch anything.

How do licence keys work?

Keys lock to the first PC that activates them — ONYX hashes your hardware into an anonymous fingerprint (like ONYX-CC72-B47B-0764) that our server checks. Week/month/year keys hold one device; Lifetime holds five. Deactivate inside the app to free the seat and move to a new machine.

What exactly does VIP unlock?

611 premium tweaks across GPU packs, power, network, memory, input latency, services debloat and privacy — plus the BIOS adviser and the full Storage hub. Premium payloads are fetched from the licence server after activation, so they're never bundled in the download.

Does it work offline?

Activation and refreshes need internet, but ONYX keeps a verified session on your machine — if the server is briefly unreachable, your cached premium session keeps working.

Windows 10 or 11?

Both, x64. Compatibility is tagged per OS and the app skips anything that doesn't apply to your build.

Refunds?

Digital goods are licence-bound, but if something doesn't work on your machine, reach out on Discord and we'll sort it out.

Ready when you are

Make it silky.

Portable, reversible, and free to start. The first optimization lands in about two minutes.
