Free grant research: how far Grants.gov and the library actually get you

You can run a credible grant research operation for nothing. Most small shops should, at least until application volume makes the convenience worth paying for.
Here is what free actually covers.
Grants.gov — all federal discretionary opportunities
The federal government’s own portal, covering every agency’s discretionary grant programs. Search, filter by eligibility and category, and subscribe to saved-search alerts.
Nothing about federal grant discovery costs money, and no paid tool has better federal coverage than the source itself. What paid tools sometimes add is a friendlier interface.
The real cost of federal grants is not finding them. It is registration — SAM.gov and the associated identifiers — and the compliance burden afterwards. Both take longer than first-time applicants expect, so start registration well before you find an opportunity you want, not after.
Candid’s Foundation Directory — free at the library
This is the one most shops do not know about, and it is the single biggest free resource in the category.
Candid partner libraries in the Funding Information Network offer full on-site access to Foundation Directory at no charge. Hundreds of locations. Not a trial, not a cut-down version — the complete database, at the desk.
For a small shop, two scheduled afternoons before your fall application push covers the diligence on a whole season’s worth of prospects. Find your nearest location on Candid’s site, confirm the hours, and block the time like a meeting.
The catch is real and worth stating: research that has to be scheduled tends not to happen. That inconvenience is the honest argument for a subscription. But paying several hundred dollars a year for search access when the same database is free twenty minutes away rarely survives a finance committee that asks the question.
Raw 990 filings — free everywhere
Every private foundation files a 990-PF including a schedule of grants paid: who got money, how much, often for what. The IRS publishes filings, Candid hosts them, and ProPublica’s Nonprofit Explorer carries them with a decent search.
This is the source that answers the question that actually decides your hit rate — is this funder a fit — and it costs nothing. See reading a 990-PF for the four numbers worth pulling.
What free cannot do
Three things, and they are the same three things you are paying for when you buy a tool.
Search across funders. Free 990s give you one foundation at a time. You cannot ask “which funders in my state gave between $10,000 and $25,000 to youth programs last year.” That question is what a database answers, and it is the difference between researching funders you already knew about and finding ones you did not.
Propose funders you did not think of. A database answers the question you asked. Matching works forward from your program profile. That is worth the most to a shop expanding into new funders and close to nothing to one stewarding twenty existing relationships.
Track deadlines across a portfolio. No free source does this. A shared spreadsheet does, if someone maintains it — and the grant reporting calendar matters more than the research tool, because a missed report costs a renewal.
The cheapest paid step up
If free plus a spreadsheet has stopped working, the next rung is small: GrantStation at about $199 a year through TechSoup, covering private, corporate and government funders with weekly alerts.
That sits inside the band for every shop under $1M — our 2026 survey put mean grant research spend at $250 a year under $250K raised and $746 at $250K–$1M. It buys you cross-funder search. It does not buy matching or a pipeline.
Instrumentl adds both, from $179/mo, which is $2,148 a year and above the band for anyone under $1M. It earns that in one situation: past roughly ten to fifteen live applications, or when more than one person is writing and the spreadsheet has started producing disagreements. Our grant research software guide works through the threshold.
The honest recommendation for a small shop
GrantStation for discovery, the library for diligence on funders that survive the first cut, and a shared calendar for deadlines. About $199 a year.
It costs time instead of money, which is the right trade when you have more of one than the other. Move up when application volume — not ambition — says you should.
Common questions
Is Candid's Foundation Directory really free at libraries?
Yes. Candid partner libraries in the Funding Information Network offer full on-site access at no charge — the complete database at the desk, not a trial or a limited version. There are hundreds of locations across the United States.
Is Grants.gov free?
Yes, entirely. It is the federal government's own portal for discretionary grant opportunities across every agency. The cost of federal grants is not the search, it is the registration and compliance burden.
Can a small nonprofit skip paid grant research software entirely?
Many should. Our 2026 survey put mean annual grant research spend at $250 for shops under $250K raised, with many spending nothing. Free federal search plus library access to Foundation Directory covers discovery and diligence; what you give up is convenience and a pipeline.
What do the paid tools add that free sources don't?
Three things: searching across funders rather than one at a time, matching that proposes funders you would not have thought to search for, and deadline tracking across a portfolio. The data itself is largely the same public 990 information.
