TongFlow vs Wavel AI

TongFlow is an open-source tool for building multimodal AI workflows on a visual canvas. Workflows can add, transform, combine, split and batch text, images, audio, video, 3D and documents, with compatible models switchable without rebuilding the workflow. Listed capabilities include text-to-video, image-to-video and AI avatars, and commercial use is supported. Users can self-host or use TongFlow Cloud through a browser or desktop app for macOS and Windows; the desktop app opens the cloud workspace and requires an internet connection. Running a workflow depends on compatible plugins and credentials for the selected providers. Self-Host is free forever. TongFlow Cloud costs $2.99 a month and includes managed hosting, per-user data isolation and encrypted credentials. New cloud accounts receive seven days without a card; eligible first-time subscribers can then start a separate seven-day trial that requires a card. Model API and GPU compute charges are billed separately by connected providers, and TongFlow does not sell generation credits. Self-hosted workflows and materials are stored locally, with no telemetry to project authors according to the privacy policy.

Wavel AI is a video creation service with text-to-video and image-to-video tools, AI avatars, and API access. It supports output up to 4K resolution and allows commercial use. Its free option provides 15 one-time credits for seven days, and videos carry watermarks; this is trial access rather than an unlimited free plan. Basic costs $25 a month and includes 100 credits per month, 10 voice clones, three AI twins, and up to 20 AI videos. Pro costs $40 a month, with 300 credits, 30 voice clones, three AI twins, and up to 50 AI videos. Scale costs $100 a month and includes 1,000 credits, 100 voice clones, 10 AI twins, and up to 200 AI videos. Wavel AI was founded in 2018 and is headquartered in Singapore. The listed platform is API, so the entry specifies API access rather than desktop or mobile platform availability. The plan limits distinguish the options by monthly credits, voice clones, AI twins, and video capacity.
