Better Files brings data rooms into your own TypeScript application. Install it, call a factory with your database and storage, and mount it into the framework you already use. It is a library, not a hosted service.
It covers everything a serious data room needs — rooms, folders, versions, granular permissions, guests, NDA gating, watermarking, share links, Q&A, e-signature, legal holds, and a tamper-evident activity log — with files encrypted at rest under a key per room. Identity and authorization come from Better IAM.
