Real-time Roblox asset proxy

Reskin your sounds.

Fleasion sits between Roblox and its servers, intercepting textures, sounds, meshes and animations — and swapping them for yours live, before the game ever loads them.

How it works

A proxy that catches every asset mid-flight.

In the default Env Proxy mode, Fleasion relaunches Roblox Player or Sober through a high localhost port and patches Roblox's own CA bundle so TLS still succeeds. Studio stays untouched; the old hosts-file route remains an optional compatibility mode.

01

Intercept

Every asset Roblox requests by ID is caught by a local proxy before it downloads from the CDN.

02

Swap

Replace by ID, redirect to a URL, serve a local file, or strip it entirely — your rules, from the dashboard.

03

Deliver

The game gets your version over the same handshake. Only you see it — nobody else is affected.

Inside the app

Same weapon. One is a Fleasion swap.

Every rule lives in a real dashboard — build replacement profiles, scrape the assets a game loads, and preview meshes, audio and animations before you commit.

Seven tabs cover the whole flow — the Scraper captures assets, the new Proxy tab inspects live traffic, and portable JSON configs keep local files beside the setup you share.

Supported games

Curated presets for the games people actually play.

What you can change

Sound, texture and sky — three swaps that define your look.

Trust & safety

Cosmetic swaps by design. Open source by principle.

The Replacer swaps or removes existing assets and cannot aim, inject items, or read game memory. v2.4.0 also includes custom FastFlags and live proxy inspection; those are advanced tools with separate account and privacy risks. The full source is public so you can verify every boundary.

FAQ

Straight answers.

The asset Replacer is cosmetic: it cannot aim, inject items, or touch game logic. v2.4.0 also manages custom FastFlags and can inspect live proxy traffic; those advanced features are not covered by the same low-risk claim and must follow Roblox and game rules.
