The short version

  • Only Obsidian has a free tier, so it costs nothing to try first.
  • Each has a real cost: Labguru ownership changed twice in short order, to Battery Ventures in 2024 and then into the Cenevo brand with Titian Software in 2025, so the medium-term roadmap is a group strategy decision rather than a product one and buyers should ask directly what happens to the notebook.; Obsidian sync is a paid add-on at $4 per month billed annually rather than part of the app
  • They diverge on capability: Labguru covers Combined ELN and LIMS, Obsidian covers Bidirectional linking.
  • 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.

Labguru

  • Ownership changed twice in short order, to Battery Ventures in 2024 and then into the Cenevo brand with Titian Software in 2025, so the medium-term roadmap is a group strategy decision rather than a product one and buyers should ask directly what happens to the notebook.
  • The validated GxP hosting option is a separate commercial line, not a configuration setting, so a lab that discovers mid-project that it needs a validated instance faces a new contract and a new price rather than an upgrade.
  • Being both an ELN and a LIMS means it is shallower than dedicated tools in each role; high-throughput sample management and deep bioinformatics workflows both hit limits that a specialist would not.
  • No pricing is published at all, and modules such as chemistry, batch records and equipment are quoted on top, so the real annual figure only appears after a sales process.
  • Validation, SOPs and periodic revalidation after vendor releases are the customer obligation on a regulated instance, and cloud release cadence means that revalidation is a recurring internal cost that never appears on the vendor quote.

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

Labguru: Who owns Labguru now?

Battery Ventures acquired it in April 2024. Since July 2025 it operates under the Cenevo brand following a merger with Titian Software.

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
Labguru: Is it an ELN or a LIMS?

Both, in one product. That is the main reason labs choose it, and also why it is shallower than a specialist in each role.

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
Labguru: Does it support GxP work?

Yes, through a separately contracted validated cloud instance. Validation for your intended use remains 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
Labguru: Is pricing published?

No. It is quoted per user per year, with modules and validated hosting priced on top.
