990 Scout is a free, no-login nonprofit lookup built from public IRS Form 990 filings: organization profiles, executive compensation, who-funds-who grant relationships, and a public API, open with no paid tier.
GuideStar, now folded into Candid, is a well-known nonprofit-data directory. Its basic organization profile is free to view; deeper financial detail, downloads, and several search and filter features are part of Candid's paid GuideStar Pro subscription. 990 Scout takes a different approach: every feature in the table below is free, with no account required.
| Feature | 990 Scout | GuideStar |
|---|---|---|
| Look up a nonprofit by name or EIN | Free, no login required | Free (basic profile) |
| Executive & officer compensation | Free, shown on every organization page | Part of the paid GuideStar Pro tier |
| Who funds whom (grant relationships) | Free: the grant graph and per-org “who funds” pages | Limited on the free tier |
| Programmatic / API access | Free, documented public API | Not offered on the free tier |
| Underlying data source | Public IRS Form 990 e-file + Business Master File | Public IRS Form 990 filings |
Figures for GuideStar reflect its publicly stated product tiers, not a claim about its underlying data quality. 990 Scout does not rate, score, or rank organizations; it presents Form 990 figures as filed.
