Best Nonprofit Website Design Agencies (2026)
.mdUpdated
The agencies that build and look after nonprofit websites, ranked on what Markleex attests of each of them.
A nonprofit needs a website to say what it does, recruit volunteers, take memberships and receive donations, with a team that turns over and a budget voted once a year. The agencies below do that work: design and development, donation forms and receipts, membership and member areas, event calendars, accessibility, and the ongoing care a site needs once it ships. They differ in who they serve, from a neighbourhood club to a national foundation, and in how much of the job they take on.
This list ranks them on facts Markleex can attest. An entity that publishes its own space here, has its relationships confirmed by other entities, and has proven the website it operates, moves up. Rank is earned, and it is the same for everyone.
The write-ups are ours. We read each site and describe what we found there, in one voice for every entry, so the list reads end to end.
Ranked by confirmed relationships with entities that hold a verified website, then by how long the entity has held a verified website. An entity that others confirm comes first.

@simafri · Confirmed relationships: 5 · www.simafri.com
Founded 2002 · Pricing Free for eligible nonprofits; Serenity for companies · Best for Registered nonprofits that want a site someone looks after

Big Duck
Based in Brooklyn, New York · Best for Nonprofits whose message needs settling before the build
Big Duck has spent thirty years on nonprofit communications alone, from Brooklyn, and its centre of gravity is the message rather than the build: brand development, campaign strategy, audience research and fundraising communications. A website comes out of that work rather than starting it, which is the right order for an organisation whose name says less than it should. The Phi Beta Kappa Society, the Guttmacher Institute and the Breast Cancer Research Foundation are among its clients.
-
Briteweb
Based in Vancouver, with Toronto and Brooklyn · Best for Foundations rebuilding brand, site and reports together
Briteweb works with nonprofits, foundations and social impact organisations, and pairs brand strategy and visual identity with the website, the campaign and the annual impact report, so one team carries the story across all of them. It runs from Vancouver, with offices in Toronto and Brooklyn, and is certified both B Corp and Living Wage. TransLash Media, Trust Her and Ribbon Community are among the organisations it names. Its work suits a foundation whose identity and site are due for the same rebuild.
-
Constructive
Based in Jersey City, New Jersey · Best for Foundations and advocacy groups repositioning a brand
Constructive leads with brand strategy and positioning, then designs the system that carries it, so the website arrives after the organisation has settled what it stands for. Its practice covers branding, design systems, content strategy and web design, and it works with climate and environment groups, foundations and philanthropy, think tanks, public interest law, research and science. The Environmental Defense Fund, American Forests, the Rocky Mountain Institute, the FrameWorks Institute and the Endangered Languages Project are among its clients. It works from Jersey City.

Cornershop Creative
Best for Nonprofits rebuilding a site that has to talk to a CRM
Cornershop Creative works for nonprofits alone and says it has earned the trust of more than 600 of them, across animal welfare, education, environment, faith, health and advocacy. It designs and builds on WordPress and WooCommerce, and wires the site into the tools a fundraising team already runs, EveryAction, Engaging Networks, Salesforce, Funraise. Web accessibility monitoring is a service in its own right rather than a box ticked at launch. It also manages Google Ad Grants and paid campaigns, and keeps sites on maintenance plans that carry no long-term contract.

Firefly Partners
Best for Nonprofits whose fundraising, marketing and data sit in silos
Firefly Partners is a women-led, B Corp certified agency that treats a website as one piece of a larger machine, alongside the CRM, the email programme and the data that moves between them. Its work covers website design and redesign, marketing technology implementation, digital fundraising infrastructure, automation and analytics, and it frames the job as aligning people, process and technology rather than shipping a design. The Southern Poverty Law Center, Kids In Need of Defense, Caring Across Generations and AIDS/LifeCycle are among the organisations it names.
-
Forum One
Best for Large associations and institutions with complex sites
Forum One builds for the largest mission-driven institutions, and its client list says which league it plays in: AARP, the Smithsonian Institution, the Natural Resources Defense Council and United States federal agencies. It covers strategy, design, data and technology, and works with nonprofits, associations, foundations, think tanks, cultural institutions and governments worldwide. Its recent writing runs to artificial intelligence, workforce development and digital engagement, which is where its larger clients are spending.
