In their own words
Knockout API
Knockout API provides image and video processing through a browser app and API. Its image tools cover background removal and replacement, batch processing, masking, smart crop, stickers, outlines, shadows, and inpainting; the API also handles upscaling, portrait restoration, colorization, and object removal. Video background removal runs asynchronously, with job polling for progress. The browser Canvas supports layered designs with text and effects, and users can save canvases and cutouts to a free account. Developers can connect through REST, any HTTP client, or official Node, React, Python, and CLI options. The service says it manages GPU processing, endpoint updates, usage records, credentials, teams, and billing. Its privacy policy says uploaded images are processed in GPU worker memory, not retained after the response, and not used to train models. The Free plan is free, with 30 images per month and 60 requests per minute. Pay-as-you-go is $0.02 a month, with metered usage billed monthly; Plus is $10 a month. Paid tiers have no monthly cap and a 600-request-per-minute limit.
unscreen.io
unscreen.io removes video backgrounds with AI, without requiring a green screen. Its web uploader accepts MP4, MOV, WebM, AVI, MKV, and GIF files. The free browser plan offers processing up to 1080p without time limits or an account, but supports WebM only, has no sound or storage, and uses limited bitrate. Premium plans support exports up to 4K with audio, no watermark, API access, and a commercial license; prices start at $2.97 per month. Premium processing offers Portrait Mode at 1 credit per second and Studio Quality at 4 credits per second. Unscreen Studio adds real-time background removal, virtual camera output, live face swap, video file processing, custom backgrounds, and a media downloader. The virtual camera can supply Zoom, OBS, Teams, or any camera-compatible application. Studio processes frames on the user's machine and says footage is not uploaded, streamed, or stored in the cloud. For cloud processing, videos remain available for download for 30 days before automatic deletion. The product also provides a REST API with a Node.js SDK.
