After running it commercially, I open-sourced my entire cloud storage + docs + e-signature platform under (MIT)
I built a self-hosted alternative to Dropbox + Google Docs + DocuSign, and running it as a commercial SaaS. Today the entire codebase is open source under MIT — the platform and the operator console, with no held-back "enterprise edition."
Highlights: per-tenant encryption at rest (the storage provider only sees ciphertext), sharing + file-request portals, in-browser office co-editing (Collabora/WOPI), PDF tools, e-signatures with PKCS#7-sealed documents, and the full business layer (Stripe billing, seats, metering, support desk) if you want to run it for others.
It's built to be readable: one Go binary per service, a React app embedded in the executable, Postgres for everything. Docs, env examples, and a systemd unit are in the repo.

I'm the author — feedback, issues, and PRs (an S3/MinIO storage backend is top of the wishlist) are very welcome.
