JDownloader is a free, open-source download manager that automates and organizes downloads from file-hosting services. It supports batch downloading, pause/resume, bandwidth control, archive extraction, and proxy rotation.

JDownloader runs on Windows, macOS, Linux, and can be operated remotely using the My.JDownloader web interface.

 It supports a wide range of hosts like Mega, Rapidgator, Uploaded, Nitroflare, Zippyshare, and more. However, support often breaks when hosts update their anti-bot systems or CAPTCHA logic.

Not reliably. It can display CAPTCHA popups for manual solving or use basic plugins (e.g., 2Captcha, 9kw\.eu), but these are often slow, outdated, or inaccurate, especially with reCAPTCHA v2 or image-click CAPTCHAs.

While the project is still available, plugin updates are inconsistent, and many premium or free host integrations frequently break, leading to a 0/5 user rating in some recent feedback.

Most free hosts require CAPTCHA solving, wait times, or session verification. If these aren't handled, JDownloader **pauses or skips the download**, especially when unattended.

CaptchaAI can solve modern CAPTCHAs that JDownloader's default solvers can't, such as reCAPTCHA v2/v3 and image puzzles. This makes it possible to **run downloads 24/7 without human input**.

Yes. CaptchaAI supports the **2Captcha-compatible API**, so you can configure it under JDownloader's **external CAPTCHA solver settings** by entering your CaptchaAI API key in place of 2Captcha.

Only when combined with tools like **CaptchaAI**. On its own, it’s unable to bypass many modern CAPTCHA gates—making automation unreliable without human interaction.

Go to **Settings > CAPTCHA > 2Captcha**, and input your **CaptchaAI key** and endpoint (`https://ocr.captchaai.com/in.php`). This allows JDownloader to send CAPTCHAs to CaptchaAI and retrieve solutions automatically.
