How to Fund Your Open Source Project in 2026
A step-by-step guide to choosing and setting up funding for your open source project, from first donation to sustainable income.
You maintain an open source project and want to explore funding. Here’s a practical roadmap based on where your project is today.
Step 1: Understand your options
Open source funding falls into three broad categories:
- Donations and sponsorships — Recurring or one-time support from your users and community. Platforms: GitHub Sponsors, Open Collective, Ko-fi, Liberapay.
- Revenue from your project — Paid support, commercial licenses, content, or services built around your work. Platforms: Tidelift, Algora, Gumroad.
- Grants — One-time or recurring funding from foundations and programs. Examples: Sovereign Tech Fund, NLnet, NumFOCUS.
Step 2: Start with the lowest-effort option
For most projects, the right first move is GitHub Sponsors:
- Enable GitHub Sponsors on your profile (takes 10 minutes)
- Add a
FUNDING.ymlfile to your repo (GitHub shows a “Sponsor” button) - Add a one-line mention in your README: “If this project is useful to you, consider sponsoring”
This takes under 30 minutes and creates a permanent funding surface with zero fees.
Step 3: Match your situation to a strategy
| Your situation | Recommended approach |
|---|---|
| Solo maintainer, small project | GitHub Sponsors + Ko-fi |
| Popular library used by companies | GitHub Sponsors + Tidelift |
| Project with a team | Open Collective + GitHub Sponsors |
| Infrastructure / public good | Apply for grants (Sovereign Tech Fund, NLnet) |
| Developer tool with power users | Paid features or support tier (Gumroad, Polar) |
Step 4: Make it easy to give
The biggest barrier to funding is discoverability. Make sure:
- Your repo has a
FUNDING.ymlfile - Your README mentions funding in the first few screens
- Your project website (if any) links to your funding page
- Your release notes thank sponsors
Step 5: Scale when ready
Once you have initial traction (any amount of recurring funding), consider:
- Adding a second platform to reach different donor types
- Applying for grants relevant to your ecosystem
- Offering paid support or consulting through your project
