Developers, indie SaaS teams, and automations that push a lot of video through a small number of profiles.
Upload-Post is the easy recommendation for developers who care about price first and video handling second. The $16 plan still covers 5 profiles with unlimited uploads, and the server-side FFmpeg layer matters in practice: our 240 MB 4K test clip cleared here without the file-prep work some rivals push back onto you.
Low-cost posting API with unlimited uploads and server-side FFmpeg that does real video work.
