The record

Purpose: Cobalt helps users save video, audio, photos, and GIFs from websites by pasting a link.
Pricing model: Cobalt describes itself as a service made for public benefit and not for profit, and invites users to support it with donations.
Ads and tracking: Cobalt says it has no ads or trackers and does not store or track information about individual people.
Supported services: The homepage has a supported-services section, but the opened page did not expose the service names.
Local processing: Cobalt says remuxing and transcoding can happen directly on the user's device; its remux page says files stay on the device.
Remux formats: The remux page lists MP4, WebM, MP3, OGG, Opus, WAV, and M4A as supported formats.
Remux behavior: Cobalt says remuxing copies existing codec data into a new container without re-encoding the media.
Privacy: Cobalt says temporary tunnel data is encrypted with AES-256, stored in server RAM for 90 seconds, and then irreversibly purged.
Analytics: Cobalt says it uses self-hosted Plausible for anonymous, aggregated traffic analytics and provides an option to opt out.
Security services: Cobalt says it uses Cloudflare for DDoS and abuse protection, bot protection through Turnstile, and hosting and deployment of the web app.
Self-hosting: Cobalt says it is easily self-hostable and provides instructions for running a processing instance with Docker Compose.
Support: Cobalt directs bug reports and recurring issues to GitHub and other questions to Discord; support is best effort and not guaranteed.
Limits: Cobalt says its downloader can only download free and publicly accessible content.
Community instances: Cobalt warns that it does not control community processing instances and advises users to choose hosts they trust.
