Quick answer
Open source marketing is growing adoption of an open-source project, or a product built on one, through the channels open source already has: the README, GitHub activity, contributor communities, package registries and developers writing about what they use.
Open source marketing
DefinitionAn open-source project has no sales motion: adoption is an install, a star, a dependency added. Its marketing is the README that reads like a landing page, the release notes developers actually read, the issues answered quickly, and the contributors who become advocates because they were treated well.
Where does an open-source project get its users?
From the places developers already look: the package registry and GitHub search, the README that a search landed on, a mention in a thread or a newsletter, a dependency another project pulled in, a talk, a "Show HN" or a launch post, and increasingly an AI assistant that cites the project when asked for a tool. None of these is a campaign; all of them reward a project that is easy to find, try and recommend.
The README is the landing page. It should say what the project does in one sentence, show the install and a working example in the first screen, state the licence and the status, and link to the docs. Most projects lose adopters in the first thirty seconds of the README.
What should an open-source launch include?
- A release that is worth a post: a feature, a benchmark, a migration, a milestone.
- The post itself, written by a maintainer, with the problem, the design and the numbers.
- The places it goes: the project's channels, the communities on that stack, link aggregators, the relevant newsletters, and promoted distribution in developer feeds for the tags it covers.
- Somewhere to land: a README and docs ready for a wave of new people, and issues triaged before the wave arrives.
- A reason to come back: a release cadence and a changelog people can follow.
Launches bring waves; retention comes from the cadence between them.
Common mistakes
- A README that explains the architecture before the install command.
- Counting stars and reporting them as users.
- Launching before issues are triaged, then drowning in the wave.
- Moving features from free to paid quietly; the community notices first.
How developers experience it
- They judge a project by its README, its last commit date and its open issues.
- They adopt what their dependencies and their peers already use.
- They forgive a missing feature and never forgive a bait-and-switch.
How do you market the paid product without alienating the community?
Keep the free project complete for its purpose. Say plainly what the paid version adds and for whom (scale, support, hosting, compliance), and never move a feature from free to paid without notice and a reason. Market the project on its own merits and the paid tier on its own, and let the community promote the one it trusts.
The companies that manage this well treat the open-source project as the top of the funnel and the community as the asset, and they report to their board on both: installs and contributors, and the share of paying customers who started with the free project.
Which metrics matter for open-source marketing?
Installs or downloads from the registry (stars are a vanity metric on their own), active instances if the project reports home, contributors and first-time contributors, issue response time, documentation search success, and for commercial projects the conversion from free project to paid customer. Track mentions and citations too: open-source projects are what AI assistants most often recommend for developer questions.

How it works on daily.dev
A release post or a maintainer's 'how we built it' story is the kind of post daily.dev readers upvote. In-Feed Ads put it in front of developers on the project's stack, and a verified company page gives the project a home they follow between releases.
