FleasionproxyAbout Fleasion
We're the small team behind Fleasion — the free, open-source app that lets you customize how your Roblox looks and sounds. This page is the straight answer to "who actually makes this?", because we think a tool that touches your system should tell you exactly who's behind it.
Who's behind Fleasion
Fleasion was started by crop (@cro.p), and it's built and maintained by a small group of contributors: @8ar, @yoloblokers, @decooooo and @3tcy, with community support from @jan_darkk, @tm2k and @rang_tanga. We're players ourselves — Fleasion started as something we wanted for our own games, and it grew from there.
We're not anonymous, and we're not a "download site." The code has our names on it, the project lives on GitHub under our own organization, and we're around every day in our Discord.
What we build, and why
We started with cosmetic asset customization for Roblox. The Replacer swaps existing sounds, textures, meshes and skyboxes on your client; it cannot aim, add items or read game memory. The project now also includes custom FastFlags and proxy diagnostics, which carry separate account and privacy warnings. The honest boundaries are on Is Fleasion safe?.
How Fleasion is made
- Open-source, GPL-3.0. Every line is public on GitHub. You can read it, or build it yourself and run your own copy — something we think matters for a tool like this.
- Python + PyQt6, packaged so the standalone build needs no Python install.
- Actively developed. We ship updates often and post changes in Discord, so it's worth checking back.
- Free, with no ads and no paywall. If it earned a spot in your setup, you can tip us on Ko-fi — but you never have to.
Where to find us
The fastest way to reach us, get help, share presets, or check whether Fleasion is up is our community:
- Discord — discord.gg/hXyhKehEZF: support, preset sharing, live up/down status, and update announcements.
- GitHub — github.com/fleasion/Fleasion: the source code, releases, and bug reports.
- Ko-fi — ko-fi.com/fleasion: optional support for the team.
Always download Fleasion from the official Fleasion site first, or our GitHub Releases — never a mirror or "premium" copy.
