The short version

  • Only Zotero has a free tier, so it costs nothing to try first.
  • Each has a real cost: Seven Bridges the parent merged into Velsera in 2023 alongside Pierian and UgenTec, so the platform now competes for roadmap attention with clinical interpretation and diagnostics products inside a private equity owned group.; 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.

Seven Bridges

  • The parent merged into Velsera in 2023 alongside Pierian and UgenTec, so the platform now competes for roadmap attention with clinical interpretation and diagnostics products inside a private equity owned group.
  • Pricing is not published and splits into a platform subscription plus consumption-based cloud compute, so a heavy analysis quarter produces a bill that headcount-based budgeting does not anticipate.
  • The analysis capability itself has credible open source equivalents in Nextflow and Cromwell on raw cloud, so you are principally paying for compliance and governance rather than for the science.
  • Pipelines are built around Common Workflow Language, which is a real learning curve and a portability commitment for teams whose existing work is in other workflow languages.
  • Cloud storage of large genomic datasets accrues continuously whether or not you are analysing, and egress charges apply when moving results out, both of which are outside the subscription line.

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
