The short version

  • Only Obsidian has a free tier, so it costs nothing to try first.
  • Each has a real cost: Obsidian sync is a paid add-on at $4 per month billed annually rather than part of the app; Thermo SampleManager LIMS no pricing is published in any form, and Thermo Fisher routes even basic cost questions through a request for quote, so early stage budget planning is guesswork.
  • They diverge on capability: Obsidian covers Bidirectional linking, Thermo SampleManager LIMS covers Sample lifecycle management.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

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

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

Thermo SampleManager LIMS

  • No pricing is published in any form, and Thermo Fisher routes even basic cost questions through a request for quote, so early stage budget planning is guesswork.
  • Implementation is configuration heavy and normally requires Thermo Fisher professional services or a specialist partner, and services costs routinely exceed the licence cost in the first year.
  • Computer system validation is the customer responsibility on top of implementation, so a GMP laboratory carries a validation programme of its own before go live and repeats a subset of it at every upgrade.
  • Cloud hosting is charged as an annual fee scaled to licence count, so seats drive infrastructure cost as well as licence cost and occasional users are expensive twice.
  • The product carries a long codebase history and its configuration model is specialist, which makes in house administrators hard to recruit and creates a dependency on external consultants for changes that would be self service in a newer LIMS.
