The short version

  • Only Zotero has a free tier, so it costs nothing to try first.
  • Each has a real cost: TetraScience pricing is scoped on connected instruments and data engineering effort rather than a published unit, so the cost of adding a new laboratory or an acquired site is impossible to forecast without going back to the vendor.; Zotero free account storage is limited; paid tiers start at $20/year for 2GB and reach $120/year for unlimited storage
  • 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.

TetraScience

  • Pricing is scoped on connected instruments and data engineering effort rather than a published unit, so the cost of adding a new laboratory or an acquired site is impossible to forecast without going back to the vendor.
  • Value depends entirely on connector coverage for your actual instrument estate; an instrument type without an existing productised connector becomes a services engagement with its own timeline and cost.
  • The GxP package is a separate annual subscription rather than an included capability, so a company that starts in research and later needs regulated use faces an additional commercial line and a validation exercise.
  • It is infrastructure with no end-user application of its own, so the business case rests on downstream analytics and AI work that has to be resourced and delivered separately before anyone sees a benefit.
  • Deployment is a multi-year programme touching instruments, networks, validated systems and site IT, and organisations consistently underestimate the internal effort required from people who also have day jobs running the laboratory.

Zotero

  • Free account storage is limited; paid tiers start at $20/year for 2GB and reach $120/year for unlimited storage
  • Sync and web access are optional add-ons layered on the core desktop app rather than included outright

Answered from the vendors’ own pages

TetraScience: What is the pricing unit?

Connected instruments and the scope of data engineering, over a fixed contract term. There is no published per-seat or per-gigabyte rate.

Zotero: How much storage does Zotero's free tier provide?

The free tier includes 300 MB of storage for research materials, citations, and related files. Collaboration features in group libraries are available at no additional cost.

Source
TetraScience: Does it replace my ELN or LIMS?

No. It sits underneath them, harmonising instrument data and making it available to whatever applications you already run.

Zotero: What are the pricing tiers for Zotero paid storage plans?

Zotero offers three paid storage tiers: 2 GB for $20 per year ($1.67 monthly), 6 GB for $60 per year ($5 monthly), and Unlimited storage for $120 per year ($10 monthly).

Source
TetraScience: Is it usable in a GxP environment?

Yes, with the separately subscribed Tetra GxP package. It reduces validation effort substantially but does not eliminate your validation obligation.

Zotero: Do group libraries count against storage limits in Zotero?

Group library file storage draws from the group owner's personal storage account, not a separate quota. Collaboration in group libraries is available at no additional charge.

Source
TetraScience: Can I get the harmonised data out?

Yes. Tetra Data is designed to be accessible to your own analytics tools rather than confined to the platform.
