Where each one falls short

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

Fluxx

  • Configuration flexibility means the system does very little until someone configures it, and foundations without a dedicated systems administrator end up paying the vendor or a partner for every change.
  • Implementation commonly runs four to eight months and is priced separately from the subscription, so first-year cost is far above the annual licence figure.
  • No pricing is published and quotes scale with assets under management, which means two foundations making the same number of grants can be quoted very differently.
  • The card-based interface is unfamiliar to new users and reviewer adoption suffers without training, which matters because trustees use it a few times a year and forget between meetings.
  • Reporting is capable but the report builder is technical, and many foundations end up exporting to a spreadsheet or a BI tool for board-ready output.

GuideStar

  • GuideStar and Foundation Directory are being retired and merged into a single Candid platform, per Candid's own learning.candid.org help pages, with existing subscribers redirected to log in at app.candid.org
  • Candid's own pricing page lists Candid Premium (annual) at $1,199 per year in USD, and $219 per month if billed monthly, with an Ultimate annual tier at $1,699 per year adding compliance monitoring features
  • Candid's free tier limits search results, profile views and dashboards; full grants and profile data downloads are capped even on Premium annual, at 1,000 grants downloads and 5,000 profile downloads per month

Answered from the vendors’ own pages

Fluxx: Is Fluxx Grantseeker really free?

Yes, for applicants. It is the submission portal, and funders pay for Grantmaker.

Fluxx: How is Fluxx priced?

By quote, scaling with assets under management and grant volume. Implementation is a separate professional services fee.

Fluxx: Can we configure Fluxx ourselves?

Yes, that is the point of it. But it requires a trained internal administrator; foundations that do not appoint one become dependent on paid services.

Fluxx: How long does implementation take?

Typically four to eight months for a multi-programme funder, driven mostly by how long the foundation takes to agree its own process.
