Low-barrier platforms suited to single-workspace or internal integrations with minimal review.
4 marketplaces in this directory match this tag.
Simple/internal platforms — Notion, Firefox Browser Add-ons, Setapp, Coda — have the lowest barrier to publish in this directory: little or no formal review, straightforward auth, and a build that can go from prototype to installed in days. They are the best place to start if you are building your first marketplace integration or shipping something for internal/single-workspace use only.
The trade-off for the low barrier is typically a smaller or less monetizable audience than the heavier-review, marketplace-app tier — these platforms optimize for developer velocity over enterprise-grade certification, so match your expectations accordingly.
