132 open-source projects, every one verified live against the GitHub API. What we take, what we copy, and what we only read — to build a creator studio that runs on the creator's own machine with no expiring credits.
The shape of the field: the pipeline is barbell-shaped. The middle — voice, assembly, subtitles, publishing — is extraordinarily well served, with several production-grade options each. Both ends — what to make and getting paid — are close to empty, because they need proprietary data or a two-sided market. That asymmetry is the product opportunity.
What to make. Near-empty in OSS — every serious tool is a SaaS.
