How to back a open-source tool dream in Dublin safely

Backing a open-source tool dream means giving to a real person with a real goal. You see the plan before you give, money is held per milestone and you decide when each part is released.

An open-source tool needs more than public code: installation, tests and contributor guidance make it usable. Fund a defined technical scope with visible changes and reproducible examples.

How Backers are protected

14-day review per milestone

When proof is posted, each Backer has 14 days to release their share or ask for more. Money not released in time goes back to the Backer.

15% fee, deducted — never added

Backers pay exactly what they choose. The 15% fee comes out of each backing: €100 gives the Dreamer €85. The fee is kept if money is returned.

Gifts, not shares

Backings are gifts. No shares, equity, interest or repayment, and Dreamers keep full ownership. Nothing on cohero is an investment or a loan.

  1. 01

    Before you back

    Read the story and the milestones. Check that the amounts add up and that each step has something concrete to prove. If anything is unclear, ask in chat first.

  2. 02

    While the dream runs

    Your backing is split across the milestones. When proof is posted you are notified and can release your share or ask for more. You can back anonymously.

  3. 03

    If something goes wrong

    If you do not release a milestone in time, the money still held for it and later steps comes back to you, minus the fee. You can report a dream or block a user at any time.

Example milestone plan

An example plan for a open-source tool dream with a goal of €7,100. Backers fund the whole goal, but each milestone's money stays held until you post the proof and Backers release it.

  1. Milestone 1

    €1,775 · 25%

    Publish the technical scope

    Post a repository link, a design note and a minimal runnable example explaining the problem and the planned interfaces.

  2. Milestone 2

    €2,485 · 35%

    Implement the core tool

    Share tagged source changes, automated test output and a recorded example showing the main function with sample inputs.

  3. Milestone 3

    €1,775 · 25%

    Check compatibility and docs

    Upload a compatibility matrix, fresh installation results and draft documentation tested against the current version.

  4. Milestone 4

    €1,065 · 15%

    Prepare contributor release

    Post release notes, contribution instructions and an issue triage plan with links to the final examples and known limitations.

Risks to plan for

  • R1

    Dependencies break compatibility

    An upstream change can make installation fail even when the tool code is unchanged. Define supported versions early and budget for automated compatibility checks and fixes.

  • R2

    Maintainer workload expands

    Support requests can displace planned development work. Limit the funded feature scope and reserve the final milestone for contribution guidance and a manageable issue triage plan.

  • R3

    Examples hide setup problems

    A tool may run only in its creator’s environment. Include fresh installation tests on the supported setups and fund documentation fixes before presenting the release as complete.

Questions and answers

Can I see how my money was used?

Yes. Each milestone shows the Dreamer's proof, how much is held and how much is released. You only release money for milestones you have reviewed yourself.

Why fund an open-source tool if anyone can use the code?

The dream can fund the engineering, testing and documentation needed to make public code useful. Explain the specific work being supported and provide repository evidence rather than implying Backers buy exclusive access.

What counts as proof when the work is mostly maintenance?

Link to resolved issues, source changes and test results that show the supported versions still work. Include a reproducible example or installation check so Backers can assess maintenance beyond a list of commits.
