The short version
- Only Obsidian has a free tier, so it costs nothing to try first.
- Each has a real cost: DNAnexus no pricing is published, so an organisation cannot compare the total cost against running the same pipelines on its own cloud account until it is deep in a sales process.; Obsidian sync is a paid add-on at $4 per month billed annually rather than part of the app
- They diverge on capability: DNAnexus covers Governed data storage, 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.
DNAnexus
- No pricing is published, so an organisation cannot compare the total cost against running the same pipelines on its own cloud account until it is deep in a sales process.
- Compute and storage are billed through the platform rather than at underlying cloud list price, so the compliance envelope carries a persistent margin on every terabyte and core hour, which grows with the science rather than staying fixed.
- Data egress at genomic scale is slow and chargeable, so leaving the platform later is a real project rather than a contract decision, and that gravity weakens negotiating position at renewal.
- The regulated and validated configurations sit in a higher commercial tier than the research configuration, so an organisation that starts in research mode and later needs GxP faces a repricing rather than a setting change.
- Bioinformaticians used to running Nextflow on their own infrastructure find the platform abstractions constraining, and porting an existing pipeline into the app model is engineering work that does not carry over to any other platform.
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

Questions people ask
- Is DNAnexus or Obsidian better?
- Neither clearly leads. DNAnexus starts at On request and Obsidian at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
- Which is cheaper, DNAnexus or Obsidian?
- Obsidian has a free tier; the other does not. Paid plans start at On request for DNAnexus and Free for Obsidian.
- Does DNAnexus or Obsidian run on more platforms?
- DNAnexus runs on Web, Linux. Obsidian runs on Web, Windows, macOS, Linux, iOS, Android.
- Can I use Obsidian for free?
- Yes. Obsidian has a free tier, so you can try it without paying. DNAnexus starts at On request.
- What is DNAnexus best used for?
- DNAnexus is most often used for a clinical diagnostics laboratory that needs a clia and cap aligned environment for production sequencing pipelines without building the compliance evidence itself, a pharma sponsor analysing genomic endpoints in a registrational programme where 21 cfr part 11 records are required, a biobank or consortium giving hundreds of external researchers governed access to a dataset too large to distribute, a diagnostics vendor packaging its pipeline as a versioned app so partner laboratories can run it without receiving the source code. Of those, a clinical diagnostics laboratory that needs a clia and cap aligned environment for production sequencing pipelines without building the compliance evidence itself and a pharma sponsor analysing genomic endpoints in a registrational programme where 21 cfr part 11 records are required are not what Obsidian is typically brought in for.
- What can DNAnexus do that Obsidian cannot?
- DNAnexus covers Governed data storage, Workflow execution, App building, Controlled collaboration. Obsidian covers Bidirectional linking, Graph view visualization, Markdown support, Local file storage.
Answered from the vendors’ own pages
DNAnexus: Why pay for DNAnexus instead of raw AWS?
For the compliance evidence. GxP, FedRAMP, CLIA, CAP and Part 11 coverage removes a validation programme most organisations would otherwise have to build and maintain themselves.
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.
SourceDNAnexus: Is validated use included?
No. Regulated and validated configurations sit in a separate commercial tier from ordinary research use.
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.
SourceDNAnexus: Can I get my data out?
Yes, but egress at genomic scale is chargeable and slow, so plan exit costs at the point of signing.
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.
SourceDNAnexus: Does it host UK Biobank?
Yes, DNAnexus hosts the UK Biobank research analysis platform, which has its own access approval and cost terms.
