To fund an open source project in 2026, start with the simplest visible funding surface, then add a second route that matches your project stage. Most projects should begin with GitHub Sponsors, Open Collective, or another donation option. Mature projects can add grants, paid support, Tidelift, bounties, content, or infrastructure support.

Step 1: Choose the problem you are solving

Open source funding is confusing because different models solve different problems.

ProblemBetter funding model
People want to support the maintainerSponsorships and donations
The project has shared expensesOpen Collective or fiscal host
You need to fund a defined piece of workGrants, bounties, or contracts
Companies need assurancePaid support or enterprise maintainer programs
You have teaching demandBooks, courses, workshops, or paid content
You need to reduce costsInfrastructure credits and maintainer tooling

Do not copy another project’s funding setup blindly. Match the funding route to the current bottleneck.

Most projects should add a funding link before doing anything complex.

Minimum setup:

  1. Enable GitHub Sponsors, Open Collective, Ko-fi, Liberapay, or another primary option.
  2. Add .github/FUNDING.yml to the repository.
  3. Add one sentence to the README.
  4. Link the same funding option from the project website.

This does not guarantee income. It removes the first barrier: people cannot fund what they cannot find.

Step 3: Pick the right model for your stage

Project stageRecommended first moveAdd later
New solo projectGitHub Sponsors or Ko-fiContent, consulting
Active solo maintainerGitHub Sponsors plus README askTidelift, grants, support
Team projectOpen CollectiveGrants, company sponsorships
Critical infrastructureGrants, foundations, company sponsorsTidelift, support contracts
Developer tool with business usersPaid support or servicesCommercial access, training
Security-sensitive projectOpenSSF, audits, security bountiesPaid support, grants

Step 4: Make the ask specific

A weak ask says:

Support this project.

A better ask says:

Sponsorship funds issue triage, releases, documentation, dependency updates, and long-term maintenance.

For companies:

If your company depends on this project, sponsorship helps keep the package maintained, documented, and responsive to security issues.

The more specific the ask, the easier it is for people to justify support.

Step 5: Add a higher-value route

After the basic funding link is live, add one higher-value route:

  • Grants for public-good roadmap work.
  • Paid support for production users.
  • Tidelift for widely used packages that qualify.
  • Bounties for specific issues.
  • Training or content if users need education.
  • Infrastructure credits if bills are the bottleneck.

Do not add all of them at once. Add the route that matches the strongest signal from your users.

Step 6: Review quarterly

Every quarter, review:

  • Funding received.
  • Time spent on unpaid maintenance.
  • Company users or dependents.
  • Open issues that could be funded.
  • Infrastructure costs.
  • Grant or support opportunities.

Funding is not a one-time setup task. It is part of project operations.

Common mistakes

  • Waiting for a large audience before adding funding links.
  • Hiding the funding ask at the bottom of the README.
  • Applying to every grant instead of matching mission fit.
  • Using bounties for work that is continuous.
  • Offering paid support without defining scope.
  • Mixing personal and project funds without explaining the difference.

FAQ

What is the best way to fund an open source project?

For many projects, the best first step is a visible sponsorship or donation option. The best long-term setup depends on project stage, users, governance, and whether companies depend on the project.

How do I get companies to sponsor my open source project?

Show how the company benefits. Explain that sponsorship funds maintenance, security, releases, and documentation. Make the sponsorship option easy to approve and easy to explain internally.

Are grants good for open source projects?

Yes, when the project fits the funder’s mission and the work has public-good value. Grants are usually slower than sponsorships or consulting.

Should every project use GitHub Sponsors?

No. GitHub Sponsors is a good default for direct maintainer support. Team projects or projects with shared expenses may need Open Collective or another project-level structure.
