FitFast Downloader
Free open-source Windows app that downloads FitGirl repacks from fuckingfast.co past the Cloudflare block that broke JDownloader 2.
Windows 10 / 11 · MIT license · No admin, no signup, no ads
Blocked by Cloudflare? If you have been trying to download a FitGirl repack from fuckingfast.co and JDownloader 2 keeps saying "Blocked by Cloudflare Site-Pro", "Cloudflare site protection", or the links come up as offline, this is the tool for you. It happens because the host changed how it hands out the real download URL, so plain download managers cannot follow the new flow. FitFast handles the new flow.
What it looks like
How it works
- Paste the FitGirl game page URL, or paste a list of fuckingfast.co links.
- FitFast uses a stealth browser to get past the Cloudflare check and reads the real signed download URL for every part.
- aria2 downloads them all in parallel with 16 connections per file so you saturate your line.
- UnRAR unpacks the whole archive set into one clean folder named after the game. Done.
Why it works when JDownloader 2 does not
fuckingfast.co switched to an HTMX-style flow where the real download URL is delivered through a response header (hx-redirect) after a POST, not a normal HTTP redirect. Vanilla download managers (JDownloader 2, IDM, FDM) only follow the standard redirect chain, so they see nothing. FitFast reads that header the way a real browser would. It also uses Camoufox, a fingerprint-hardened Firefox, so Cloudflare's bot checks pass cleanly.
Features
It scrapes every fuckingfast link from the page and queues them all.
16 connections per file via aria2, resumable, disk-cached.
If a file gets stuck on a slow CDN edge, FitFast gets a fresh signed URL and resumes.
Bundled UnRAR unpacks the whole multi-part rar set when the download finishes.
Every part lands in a subfolder named after the game so your Downloads folder stays clean.
No admin, no Python. Click install, click open, done.
FAQ
Is it free? Is it open source?
Yes and yes. MIT license. Full source is on GitHub. No ads, no signup, no telemetry.
Windows only?
Yes for now. The Cloudflare bypass depends on a bundled Windows Firefox build. Mac / Linux users can run the Python source directly if they set up Camoufox themselves.
My download says "Blocked by Cloudflare Site-Pro". Does this fix it?
Yes. That message is what JDownloader 2 says when it cannot follow the new URL flow. FitFast follows it.
Do I need to change my DNS to 1.1.1.1 or use a VPN?
No. Those workarounds fix a different, ISP-level block. FitFast solves the site-side block directly.
Is it safe to run?
The code is open, you can read every line. Windows SmartScreen may warn the first time because the installer is not code-signed. Click "More info" then "Run anyway".
Does it host any pirated files?
No. FitFast is only a download client. It downloads whatever links you paste. What you download is your responsibility, and this project is not affiliated with FitGirl or any file host.
