The short version

  • Only Obsidian has a free tier, so it costs nothing to try first.
  • Each has a real cost: Attest pricing is metered by credits, where one credit equals one survey question answered by one person, rather than a flat per seat rate; Obsidian sync is a paid add-on at $4 per month billed annually rather than part of the app

Where each one falls short

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

Attest

  • Pricing is metered by credits, where one credit equals one survey question answered by one person, rather than a flat per seat rate
  • The Basic tier caps usage at 50,000 credits; going beyond it requires upgrading to Standard (100,000), Elite (200,000) or a custom plan above 400,000
  • Additional credits purchased mid year cost 10 percent more per credit than the plan rate

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
