Best Grant Databases for Finding Funding in 2026

The best grant databases for most organizations are Grants.gov for federal funding (free), Candid for private foundation data, and Instrumentl or GrantStation for matched opportunities and deadline tracking. No single database covers every funder, so the practical answer is a combination: one free federal source, one foundation source, and free IRS Form 990 lookups to check what any funder actually gives.

Below is what each tool does well, what it costs as of October 2026, and where it falls short. Prices change, so confirm on the vendor's page before you buy.

The databases compared

Grants.gov and Simpler.Grants.gov

Grants.gov is the official listing for federal grant opportunities, and every federal agency posts its competitive funding notices there. It is free, it is complete for federal money, and it covers nothing else: no foundations, no corporate funders, and only the state programs that pass through federal notices.

The federal government is also building Simpler.Grants.gov, a newer search interface that uses the same opportunity data. Search there if you find the classic site clunky, but you will still apply through Grants.gov or the agency system the notice names. To apply, you need an active SAM.gov registration, covered in our guide to Grants.gov registration and the Unique Entity Identifier.

One addition worth knowing: Assistance Listings on SAM.gov describe every federal program (formerly the Catalog of Federal Domestic Assistance), including formula programs that never appear as open competitions. They tell you which programs exist even when no notice is currently posted.

Candid

Candid is the organization formed when the Foundation Center and GuideStar merged, and it holds the most complete data on United States grantmakers: who they fund, how much, and where. Its search product has been reorganized into tiered plans. As of October 2026 the free tier gives limited results and one full profile view a month, Premium runs $219 a month or from $1,199 billed annually, and an Ultimate plan starts at $1,699 a year.

If you cannot justify the subscription, there are two free routes. Candid partner locations, usually libraries and nonprofit resource centers, offer free in-person access; find one through Candid's "Candid Near You" locator. Candid also runs a promotion that gives a free year of Premium to nonprofits under $1 million in revenue or expenses that earn its current Gold Seal of Transparency.

Candid's strength is giving history. You can see which organizations a foundation funded last year and at what size, which is the single best predictor of whether it will fund you. Its weakness is that much of that history comes from tax filings that lag a year or two behind.

Instrumentl

Instrumentl matches foundation, corporate, and government opportunities to a project profile you set up, then tracks deadlines, tasks, and funder notes in one workspace. Its Discover plan is $299 a month billed annually ($349 billed monthly), with higher tiers at $499 and $999 a month that add application and post-award management. Every plan has a 14-day free trial with no card required.

It pays off when you apply continuously and the matching saves real staff hours. For an organization submitting four applications a year, it is usually more tool than you need; a free grant deadline tracker and Candid library access do the same job.

GrantStation

GrantStation searches United States charitable, federal, and state government funders, plus Canadian and international charitable funders, and it adds funder profiles, grant calendars, and proposal tools. Its site lists membership at $199 a year. Many nonprofits get it free or discounted through a state nonprofit association, community foundation, or library partner program, so check before buying.

The trade-off is depth. GrantStation profiles are curated rather than built from complete giving records, so for a serious foundation prospect you will still want its 990-PF.

GrantWatch

GrantWatch lists currently open opportunities, sorted by state and category, for nonprofits, small businesses, and individuals. It is useful for browsing what is open right now, and its state pages rank in search results for that reason. It is a listing service, not a research tool: it tells you a grant exists, not who the funder has historically supported. Treat every listing as a lead to verify on the funder's own site.

Research funding: Pivot-RP and GrantForward

University researchers have their own tools. Pivot-RP (from Clarivate) and GrantForward index federal, foundation, and society funding for faculty, and most universities license one of them through the research office. If you are at an institution, ask your sponsored programs office before paying for anything. For agency-specific guidance, see our guides to NIH grants and NSF grants.

The free sources most people skip

Private foundations must file Form 990-PF every year, and those returns are public. Two free tools make them searchable:

• ProPublica Nonprofit Explorer shows filings for tax-exempt organizations, including the grants schedule where a foundation lists each grant, recipient, and amount.
• IRS Tax Exempt Organization Search confirms exempt status and links to e-filed returns.

Reading a funder's 990-PF answers the questions a paid database answers: typical grant size, geographic focus, and whether it funds organizations like yours. It also says whether the foundation accepts unsolicited requests at all, and most private foundations do not, as our guide to foundation grants explains. A database listing a foundation does not mean the foundation will read your proposal.

State grant portals, community foundation websites, and corporate giving pages fill the remaining gaps. Our guide on how to find grants for nonprofits walks through those search tactics in order.

Which combination fits you

• Small nonprofit, a few applications a year: Grants.gov alerts, Candid at a partner library, and 990-PF lookups on ProPublica. Total cost: nothing.
• Active grants team with a full calendar: Candid Premium for depth plus Instrumentl for matching and tracking. The subscriptions are small against the staff time they save.
• Small budget, broad search: GrantStation, ideally through a partner that discounts it, plus free 990 lookups.
• University or research lab: your institution's Pivot-RP or GrantForward license plus agency pages on Grants.gov.

Whatever you choose, the database only produces candidates. Deciding which ones deserve an application is a separate step, explained in our guide to grant prospect research. If searching is eating your team's week, our grant research service runs these tools for you and returns a ranked list.
