asset-proxy

Sits between Roblox and its CDN as a MITM proxy — its own CA, a leaf cert minted per host — and rewrites asset downloads before they reach the client. Replace any texture, sound or mesh with a local file, all client-side; only you see it. It also rips every original asset a game loads straight to disk, and ships a live web dashboard (browser, not egui): a real-time feed of everything the client fetches, image previews, and click-to-swap. It is not an executor and does no code injection — it's a plain HTTPS proxy, the same class of tool as Burp, so there's no anti-cheat anywhere in the picture.

How it works

On startup it points Roblox's asset hostnames (assetdelivery.roblox.com, fts.rbxcdn.com) at 127.0.0.1 via the hosts file and serves them from a local HTTPS server on :443 — so the client thinks it's talking to Roblox but reaches the proxy, which presents a leaf certificate signed by a CA you install once. Per request it reads the asset id (or CDN hash); if a matching file is in ./swaps it serves that, otherwise it fetches the real asset — resolving Roblox's true IP first so it never loops back through the hijacked name — streams it, and caches the original. Needs root (Linux) or admin (Windows) to edit the hosts file and bind :443. A CONNECT proxy on :8080 is kept as a fallback for proxy-aware clients.

The dashboard

A second server on :8081 serves a hand-built web UI: a live table of every asset the client pulls, with type badges, sizes, image thumbnails straight from the cache, and a one-click swap (pick a local file, it's replaced on the next fetch). No desktop toolkit, no egui — just open it in a browser.

Not an executor

It runs entirely outside Roblox. No injection into RobloxPlayerBeta, no VM hooking, no Hyperion — the client just talks HTTPS through a proxy it trusts. That's the whole reason it's a clean, buildable tool where a real executor isn't.
