Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Florence eBinders

  • Pricing is set against how much your sponsors are expected to reimburse rather than a rate card, so two similar sites can pay materially different amounts and neither has a public benchmark to negotiate against.
  • It is site-side only: it does not do electronic data capture, study budgeting or full trial management, so a research office still runs a CTMS and an EDC alongside it and pays for the interfaces between them.
  • The benefit case depends on sponsors and monitors actually using remote access; if your sponsor mix insists on on-site source data verification, you have digitised the binder without removing the visits that made it expensive.
  • Migrating years of existing paper and scanned regulatory documents into structured, indexed binders is a substantial one-off project that sites routinely underestimate and that is scoped and charged separately.
  • Adoption is heavily United States centred, so a European or Asian site will find fewer sponsors familiar with the platform and less mature alignment with local regulatory expectations than a domestic site enjoys.

Obsidian

  • Sync is a paid add-on at $4 per month billed annually rather than part of the app
  • Publishing to the web is a further $8 per month per site
  • Commercial use asks for a $50 per user per year licence, though the vendor states it is not required
  • Collaboration is limited compared with a hosted notes tool, since the vault is local files first

Answered from the vendors’ own pages

Florence eBinders: Is this an EDC system?

No. It manages the site regulatory binder and source documents. Trial data capture is a separate system such as Medidata, Castor or REDCap.

Obsidian: Is Obsidian free?

Yes. The core Obsidian application is 100% free for personal and commercial use with no limitations. You can use unlimited vaults and every core feature without payment.

Source
Florence eBinders: Who normally pays for it?

The site buys it, but sites commonly recover the cost through per-study sponsor budgets, and Florence prices with that expected reimbursement in mind.

Obsidian: What file format does Obsidian use?

Obsidian stores every note as a plain Markdown file. Because it uses standard Markdown instead of a proprietary format, your notes remain portable and can be edited with many other Markdown editors.

Source
Florence eBinders: Does it support 21 CFR Part 11?

Yes, with electronic signatures, audit trails and access controls. Validation for your intended use is still your responsibility.

Obsidian: Can I collaborate with others in Obsidian?

The core application does not include built-in team collaboration features. However, Obsidian offers optional add-ons and can be used with version control systems or cloud storage for collaboration.

Source
Florence eBinders: Can sponsors see our documents?

Only what you grant through SiteLink. Documents stay under site control rather than in a sponsor-owned repository.
