General & Service Capabilities
Q.Is StreamCatch completely free to use?
Yes. StreamCatch is 100% free with no mandatory account creation, subscriptions, or hidden charges. You can resolve and download authorized media streams immediately.
Q.Which platforms and social networks are supported?

Q.Can I download private, friends-only, or paywalled videos?

Security & Anti-SSRF Defense
Q.What is Anti-SSRF defense and why is it necessary?
Server-Side Request Forgery (SSRF) is an attack vector where a server is coerced into querying internal services. StreamCatch implements strict DNS pre-flight verification and socket IP pinning to block private subnets (RFC 1918), loopback addresses (127.0.0.1), and cloud metadata endpoints (169.254.169.254).
Q.Does StreamCatch store my downloaded files on its servers?
No. We operate under a strict Zero Storage policy. Ephemeral 5-minute cryptographic tickets stream bytes directly from upstream CDN clusters to your device. No video files or media recordings persist on our web servers.
Q.How does the 5-minute signed download ticket work?
When you select a format, StreamCatch generates an HMAC-SHA256 signature binding the stream URL, container format, and expiration timestamp. This allows secure, tamper-proof direct streaming.
Formats, Codecs & Quality
Q.What resolutions and video qualities are offered?
StreamCatch offers 4K Ultra HD (VP9/WebM), 1080p Full HD (60fps H.264), 720p HD, and 480p standard definition depending on the source video.
Q.Can I extract audio only in high-fidelity MP3 or FLAC?
Yes. You can extract standalone audio stems in 320 kbps constant bitrate MP3 or 24-bit lossless FLAC from supported music and speech recordings.
